Food Labeling; Gluten-Free Labeling of Fermented or Hydrolyzed
Foods
AGENCY: Food and Drug Administration, HHS.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA or we) is issuing a
final rule to establish requirements
[[Page 49241]]
concerning ``gluten-free'' labeling for foods that are fermented or
hydrolyzed or that contain fermented or hydrolyzed ingredients. These
requirements f are needed to help ensure that individuals with celiac
disease are not misled and receive truthful and accurate information
with respect to fermented or hydrolyzed foods labeled as ``gluten-
free.'' Currently, FDA knows of no scientifically valid analytical
method effective in detecting and quantifying with precision the gluten
protein content in fermented or hydrolyzed foods in terms of equivalent
amounts of intact gluten proteins. Thus, we plan to evaluate compliance
of such fermented or hydrolyzed foods that bear a ``gluten-free'' claim
based on records that are made and kept by the manufacturer of the food
bearing the ``gluten-free'' claim and made available to us for
inspection and copying. The records need to provide adequate assurance
that the food or ingredients used in the food are ``gluten-free''
before fermentation or hydrolysis. Once we identify that a
scientifically valid method has been developed that can accurately
detect and quantify gluten in fermented or hydrolyzed foods or
ingredients, it would no longer be necessary for the manufacturer of
foods bearing the ``gluten-free'' claim to make and keep these records.
In addition, because currently there is no scientifically valid
analytical method effective in detecting and quantifying the gluten
protein content in fermented or hydrolyzed foods the final rule
requires the manufacturer of these kinds of foods bearing the ``gluten-
free'' claim to document that it has adequately evaluated the potential
for gluten cross-contact and, if identified, that the manufacturer has
implemented measures to prevent the introduction of gluten into the
food during the manufacturing process. Likewise, the final rule
requires manufacturers of foods that contain fermented or hydrolyzed
ingredients and bear the ``gluten-free'' claim to make and keep records
that demonstrate with adequate assurance that the fermented or
hydrolyzed ingredients are ``gluten-free'' in compliance with the 2013
gluten-free food labeling final rule. Finally, this final rule states
that we will evaluate compliance of distilled foods by verifying the
absence of protein using scientifically valid analytical methods that
can reliably detect the presence of protein or protein fragments in the
distilled food.
DATES:
Effective date: This rule is effective October 13, 2020.
Compliance date: The compliance date of this final rule is August
13, 2021.

I. Executive Summary
A. Purpose and Coverage of the Final Rule
Celiac disease, a hereditary, chronic inflammatory disorder of the
small intestine, has no cure, but individuals who have this disease are
advised to avoid all sources of gluten in their diet to protect against
adverse health effects associated with the disease. Relevant
educational materials are available on FDA's website at https://www.fda.gov/food/food-labeling-nutrition/gluten-free-labeling-foods. In
the Federal Register of August 5, 2013 (78 FR 47154), we published a
final rule that defines the term ``gluten-free'' and establishes
requirements for the voluntary use of that term in food labeling (the
2013 gluten-free food labeling final rule). The 2013 gluten-free food
labeling final rule (now codified at Sec. 101.91 (21 CFR 101.91)) is
intended to ensure that individuals with celiac disease are not misled
and are provided with truthful and accurate information with respect to
foods so labeled. The regulation provides that when compliance with the
rule is based on an analysis of the food, we will use a scientifically
valid method that is suitable for the reliable detection of 20 parts
per million (ppm) gluten in the food and has been validated extensively
for the detection of gluten in both raw and cooked or baked products
(Sec. 101.91(c)). In the context of this rule for the Gluten-Free
Labeling of Fermented or Hydrolyzed Foods, the limit for gluten refers
to intact gluten. We established this 20 ppm limit for gluten
considering multiple factors, including currently available analytical
methods and the needs of individuals with celiac disease, as well as
factors such as ease of compliance and enforcement, stakeholder
concerns, economics, trade issues, and legal authorities. Although test
methods for the detection of gluten fragments in fermented or
hydrolyzed foods have advanced, currently, we know of no scientifically
valid analytical method effective in detecting and quantifying with
precision the gluten protein content in fermented or hydrolyzed foods
in terms of equivalent amounts of intact gluten. Thus, alternative
means are necessary to verify compliance with the provisions of the
2013 gluten-free food labeling final rule for fermented or hydrolyzed
foods, such as cheese, yogurt, vinegar, sauerkraut, pickles, green
olives, beers, and wine, or hydrolyzed plant proteins used to improve
flavor or texture in processed foods such as soups, sauces, and
seasonings.
B. Summary of the Major Provisions of the Final Rule
Section 101.91 (21 CFR 101.91) defines the term ``gluten-free'' to
mean that the food bearing the claim does not contain: (1) An
ingredient that is a gluten-containing grain; (2) an ingredient that is
derived from a gluten-containing grain and that has not been processed
to remove gluten; or (3) an ingredient that is derived from a gluten-
containing grain and that has been processed to remove gluten if the
use of that ingredient results in the presence of 20 parts per million
(ppm) or more gluten in the food; or inherently does
[[Page 49242]]
not contain gluten, and that any unavoidable presence of gluten in the
food is below 20 ppm gluten. A food that bears the claim ``no gluten,''
``free of gluten,'' or ``without gluten'' in its labeling and fails to
meet the requirements for the ``gluten-free'' claim will be deemed to
be misbranded. This final rule amends Sec. 101.91(c) to provide
alternative means for FDA to verify compliance based on records that
are maintained by the manufacturer of the fermented or hydrolyzed food
bearing the ``gluten-free'' claim and made available to us for
inspection and copying.
This final rule requires that, for foods that are fermented or
hydrolyzed and bear the ``gluten-free'' claim, the manufacturer must
have records that demonstrate with adequate assurance that the food is
``gluten-free'' in compliance with Sec. 101.91(a)(3) before
fermentation or hydrolysis. Such adequate assurance can include test
results, certificates of analysis (CoAs), or other appropriate
verification documentation for each of the ingredients used in the
food. (A CoA is a document indicating specified test results performed
on product(s) by a qualified laboratory that has certified the test
results.) Alternatively, adequate assurance can include results of
tests on the food itself, rather than the ingredients, before
fermentation or hydrolysis of the food. In addition, the final rule
requires documentation by the manufacturer that any potential for
gluten cross-contact has been adequately assessed, and where such a
potential has been identified, the manufacturer has implemented
measures to prevent the introduction of gluten into the food during the
manufacturing process. Also, for foods containing one or more fermented
or hydrolyzed ingredients and bearing the ``gluten-free'' claim,
manufacturers must make and keep records demonstrating with adequate
assurance that the fermented or hydrolyzed ingredients are ``gluten-
free'' under Sec. 101.91(a)(3) before fermentation or hydrolysis and
the potential for gluten cross-contact has been adequately assessed,
and where such potential has been identified, measures have been
implemented to prevent introduction of gluten during the ingredient
manufacturing process). This includes, but is not limited to, CoAs or
other appropriate verification documentation from the ingredient
suppliers and/or results of testing conducted by the ingredient
suppliers.
The final rule also requires that the manufacturer retain records
for at least 2 years after introduction or delivery for introduction of
the food into interstate commerce. The final rule allows these records
to be kept as original records, as true copies, or as electronic
records, and manufacturers would have to make the records available to
us for inspection and copying, upon request, during an inspection. The
records need to be reasonably accessible to FDA during an inspection at
each manufacturing facility (even if not stored on site) to determine
whether the food has been manufactured and labeled in compliance with
Sec. 101.91. Records that can be immediately retrieved from another
location by electronic means are considered reasonably accessible. The
final rule also provides that we will evaluate compliance of distilled
foods, such as distilled vinegar, by verifying the absence of protein
using scientifically valid analytical methods that can reliably detect
the presence of protein or protein fragments in the food.
C. Legal Authority
Consistent with section 206 of the Food Allergen Labeling and
Consumer Protection Act (FALCPA) and sections 403(a)(1), 201(n), and
701(a) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21
U.S.C. 343(a)(1), 321(n), and 371(a)), we are issuing requirements to
permit the voluntary use of the term ``gluten-free'' in the labeling of
foods that are fermented, hydrolyzed, or distilled, or that contain
fermented, hydrolyzed, or distilled ingredients.
D. Costs and Benefits
Full compliance with this final rule would have annualized costs of
about $7 million to $11 million per year at 3% discount rate and
annualized costs of $7 million to $11 million at 7% discount rate. For
the rule to break-even with costs, the annualized benefits would need
to be at least $8.8 million at a 3% discount rate and a $9.1 million at
a 7% discount rate. Based on our simulation analysis, the rule would
break-even with primary cost estimates discounted at 7% if at least
0.07% of estimated individuals with celiac disease following a gluten-
free diet benefit from the rule each year.

III. Background
A. Need for the Regulation/History of This Rulemaking
Celiac disease is a hereditary, chronic inflammatory disorder of
the small intestine triggered by the ingestion of certain proteins
referred to as gluten, which occur in wheat, rye, barley, and
crossbreeds of these grains. The main protein of wheat gluten is
gliadin; the similar proteins of rye and barley are termed secalin and
hordein, respectively. Both major protein fractions of gluten, gliadins
and glutenins, are active in celiac disease. All the gliadins and
glutenins subunits are reported to be harmful for individuals with
celiac disease (Ref. 1). Celiac disease has no cure, and individuals
who have this disease are advised to avoid all sources of gluten in
their diet to protect against adverse health effects associated with
the disease.
In the Federal Register of August 5, 2013 (78 FR 47154), we
published a final rule that defines the term ``gluten-free'' and
establishes requirements for the voluntary use of that term in food
labeling. The 2013 gluten-free food labeling final rule, which is
codified at Sec. 101.91, is intended to help ensure that individuals
with celiac disease are not misled and receive truthful and accurate
information with respect to foods labeled as ``gluten-free.'' The 2013
gluten-free food labeling final rule does not require manufacturers who
label their foods as ``gluten-free'' to test those foods for the
presence of gluten. However, they may choose to do so to ensure that
the food does not contain 20 ppm or more gluten. The regulation
provides that, when compliance with [the rule] is based on an analysis
of the food, we will use a scientifically valid method that can
reliably detect the presence of 20 ppm gluten in a variety of food
matrices, including both raw and cooked or baked products (Sec.
101.91(c)). We may conduct such testing to verify that foods labeled
``gluten-free'' meet the criteria for ``gluten-free'' labeling,
including the part of the ``gluten-free'' definition that states that
any unavoidable presence of gluten in the food bearing the claim in its
labeling is below 20 ppm gluten (i.e., below 20 mg gluten per kg of
food) (Sec. 101.91(a)(3)(ii)).
Through comments we received in response to the proposed rule for
gluten-free labeling of foods that appeared in the Federal Register of
January 23, 2007 (72 FR 2795) and to a related notice reopening of the
comment period that we published in the Federal Register of August 3,
2011 (76 FR 46671), we
[[Page 49243]]
became aware that fermented or hydrolyzed foods, some of which are
labeled as ``gluten-free,'' cannot be tested for a quantitative measure
of intact gluten using currently available analytical methods. In the
notice that we published in the Federal Register of August 3, 2011 (76
FR 46671 at 46673), we stated that we recognized that, for some food
matrices (e.g., fermented or hydrolyzed foods), there were no currently
available validated methods that could be used to accurately determine
if those foods contained <20 ppm gluten. We also stated that we were
considering whether to require manufacturers of such foods to have a
scientifically valid method that would reliably and consistently detect
gluten at 20 ppm or less before including a ``gluten-free'' claim in
the labeling of their foods. We requested comments on this proposed
approach as well as on whether we also should require these
manufacturers to maintain records on test methods, protocols, and
results and to make these records available to us upon inspection.
The notice explained that we interpret the term ``scientifically
valid method'' to mean a method that is ``accurate, precise, and
specific for its intended purpose and where the results of the method
evaluation are published in the peer-reviewed scientific literature. In
other words, a scientifically valid test is one that consistently and
reliably does what it is intended to do'' (78 FR 47154 at 47165).
Although test methods for the detection of gluten fragments in
fermented or hydrolyzed foods have advanced, as of August 13, 2020, we
know of no scientifically valid analytical method effective in
detecting and quantifying with precision the gluten protein content in
fermented or hydrolyzed foods in terms of equivalent amounts of intact
gluten proteins. Sandwich Enzyme-Linked Immunosorbent Assay (ELISA)-
based methods are not effective in detecting and quantifying gluten
proteins that are no longer intact as a result of fermentation or
hydrolysis since the method requires at least two epitopes to work.
Competitive ELISA-based methods that recognize a single epitope have
been developed and may eventually overcome the detection problems
encountered using current sandwich ELISA-based assays with fermented or
hydrolyzed food. While some studies have validated the reproducibility
of competitive ELISA-based test methods, the lack of appropriate
calibration standards or suitable reference materials make accurate
quantification of gluten content difficult. This uncertainty creates
problems in equating these test results to an equivalent amount of
intact gluten in the fermented or hydrolyzed product. Without reference
standards to gauge the response for detection and quantification of
gluten to produce fermented or hydrolyzed products, such quantification
is uncertain and potentially inaccurate (Ref. 2). Thus, we need other
means to verify compliance for these foods.
B. What did we propose to do?
In the Federal Register of November 18, 2015 (80 FR 71990), we
published a proposed rule to establish requirements concerning
``gluten-free'' labeling for foods that are fermented, hydrolyzed, or
distilled, or that contain fermented, hydrolyzed, or distilled
ingredients. In brief, we proposed to evaluate compliance with the 2013
gluten-free food labeling final rule of such fermented or hydrolyzed
foods that bear a ``gluten-free'' claim based on records that are made
and kept by the manufacturer of the food bearing the ``gluten-free''
claim and made available to us for inspection and copying. The records
would need to provide adequate assurance that food is ``gluten-free''
in compliance with the 2013 gluten-free food labeling final rule before
fermentation or hydrolysis. In addition, we proposed to require the
manufacturer of fermented or hydrolyzed foods bearing the ``gluten-
free'' claim to document that it has adequately evaluated the potential
for gluten cross-contact and, if identified, that the manufacturer has
implemented measures to prevent the introduction of gluten into the
food during the manufacturing process. Likewise, we proposed to require
manufacturers of foods that contain fermented or hydrolyzed ingredients
and bear the ``gluten-free'' claim to make and keep records that
demonstrate with adequate assurance that the fermented or hydrolyzed
ingredients are ``gluten-free'' in compliance with Sec. 101.91.
Finally, we proposed to evaluate compliance of distilled foods by
verifying the absence of protein using scientifically valid analytical
methods that can reliably detect the presence of protein or protein
fragments in the distilled food. We proposed to revise Sec.
101.91(b)(1), (b)(2), and (c) to state that when a scientifically valid
method is not available because the food or ingredient is fermented or
hydrolyzed, the manufacturer of such foods bearing the claim must make
and keep records regarding the fermented or hydrolyzed food that
demonstrate: (1) Adequate assurance that the food is ``gluten-free''
before fermentation or hydrolysis; (2) the manufacturer has adequately
evaluated their processing for any potential for gluten cross-contact;
and (3) where the potential for gluten cross-contact has been
identified, the manufacturer has implemented measures to prevent the
introduction of gluten into the food during the manufacturing process.
For foods for which a scientifically valid method to detect and
quantify gluten is not available because the food is distilled,
compliance would be evaluated by verifying the absence of protein (and
thus gluten) in the distilled component using scientifically valid
analytical methods that can reliably detect the presence or absence of
protein or protein fragments in the food.
IV. Legal Authority
We are issuing this final rule under section 206 of FALCPA which
directs the ``Secretary of Health and Human Services, in consultation
with appropriate experts and stakeholders,'' to ``issue a rule to
define, and permit use of, the term ``gluten-free'' on the labeling of
foods.'' Section 403(a)(1) of the FD&C Act states that a food shall be
deemed to be misbranded if its labeling is false or misleading in any
particular. In determining whether food labeling is misleading, section
201(n) of the FD&C Act explicitly provides for consideration of the
extent to which the labeling fails to reveal facts that are material
with respect to the consequences which may result from the use of the
food to which the labeling relates under conditions of use as are
customary or usual. Section 701(a) of the FD&C Act vests the Secretary
(and by delegation, FDA) with authority to issue regulations for the
efficient enforcement of the FD&C Act. Consistent with section 206 of
FALCPA and sections 403(a)(1), 201(n), and 701(a) of the FD&C Act, we
are establishing requirements for the use of the term ``gluten-free''
for fermented and hydrolyzed foods.
Because there is no scientifically valid analytical method
available that can both reliably detect and accurately quantify the
equivalent of 20 ppm intact gluten in foods that are fermented or
hydrolyzed, or that contain fermented or hydrolyzed ingredients, we are
establishing requirements for manufacturers to make and keep records
containing information that provide adequate assurance that their food
complies with the definition of ``gluten-free,'' including information
that they gather or produce about their ingredients and the details of
their manufacturing practices. These record requirements would help
ensure that the use of the term ``gluten-free'' is
[[Page 49244]]
accurate, truthful, and not misleading based on information known to
the manufacturer that FDA would not otherwise be able to access, and to
facilitate efficient and effective action to enforce the requirements
when necessary. Our authority to establish records requirements has
been upheld under other provisions of the FD&C Act where we have found
such records to be necessary (National Confectioners Assoc. v.
Califano, 569 F.2d 690, 693-694 (D.C. Cir. 1978)).
The final rule requires records only for foods for which an
adequate analytical method is not available. The records will allow us
to verify that the ``gluten-free'' claim on foods that are fermented or
hydrolyzed, or contain fermented or hydrolyzed ingredients, is truthful
and complies with the requirements of the definition. The authority
granted to us under sections 701(a), 403(a)(1), and 201(n) of the FD&C
Act not only includes authority to establish records requirements, but
also includes authority to access to such records. Without such
authority, we would not know whether the use of the term ``gluten-
free'' on the label or in the labeling of these foods is truthful and
not misleading under sections 403(a)(1) and 201(n) of the FD&C Act. The
introduction or delivery for introduction into interstate commerce of a
misbranded food is a prohibited act under section 301(a) of the FD&C
Act (21 U.S.C. 331(a)). Thus, to determine whether the food is
misbranded, and the manufacturer has committed a prohibited act, we
must have access to the manufacturer's records that we are requiring be
made and kept under sections 403(a)(1), 201(n), and 701(a) of the FD&C
Act. Failure to make and keep records, and provide the records to FDA,
as described in Sec. 101.91(c)(4), would result in the food being
misbranded under sections 403(a)(1) and 201(n) of the FD&C Act.
V. Comments on the Proposed Rule and FDA Responses
A. Introduction
We received over 500 comments on the proposed rule. We received
comments from consumers; consumer groups; trade organizations;
industry; public health organizations; public advocacy groups; and
other organizations. We have numbered each comment to help distinguish
among different topics. We have grouped similar comments together under
the same number, and, in some cases, we have separated different issues
discussed in the same comment letter and designated them as distinct
comments for purposes of our responses. The number assigned to each
comment topic is for organizational purposes only and does not signify
the comment's value, importance, or the order in which it was received.
B. Comments and FDA Responses
1. Request for Exemption for Inherently Gluten-Free Ingredients and
Enzymes
(Comment 1) Several comments stated that the rule would have the
unintended consequence of prohibiting certain inherently gluten-free
foods and ingredients from bearing a ``gluten-free'' claim. The
comments said that the added recordkeeping requirements were an
unnecessary burden on manufacturers and that, in other cases, it might
be impossible to request records from remote geographic regions for
commodity items that are fermented immediately after harvest (e.g.,
cocoa beans). The comments pointed out that some ingredients are at low
risk of contact with gluten-containing grains at harvest as well as
across the supply chain. The comments stated that FDA should make clear
in the preamble to the final rule that inherently gluten-free foods,
such as milk and dairy ingredients, vanilla beans, enzymes (grown on
media containing gluten), flavor extracts, and cocoa beans, that have a
low risk of gluten cross-contact are exempt from the final rule. The
comments requested that proposed Sec. 101.91(c)(3) not apply to foods
containing fermented or hydrolyzed ingredients derived from foods that
are inherently ``gluten-free'' and do not have a known or reasonable
probability of gluten cross-contact. Alternatively, some comments
suggested that we revise the rule to apply only to fermented foods
produced from gluten-containing grains or having a known or reasonably
foreseeable risk of cross-contact with a gluten-containing grain (e.g.,
gluten-free beers). The comments suggested that we define ``fermented
food'' for the purposes of this section as ``a food or ingredient
derived from a gluten-containing grain by fermentation.''
The comments also stated that, if we could not create an exemption,
we should clarify that testing is not required for inherently gluten-
free ingredients when there is no cross-contact with gluten-containing
ingredients. Also, if testing is done, it should only be at the
frequency necessary to prove the ``gluten-free'' claim and records
regarding cross-contact should be flexible based on ingredients and
facility. Further, the comments stated that we should clarify whether
documentation providing general information on the commodity and
regional growing practices in countries of origin would be sufficient
to meet the ``gluten-free'' claim requirements.
(Response 1) It is our experience that all foods may, at some point
during manufacture, have a risk of cross-contact with a gluten-
containing grain depending on manufacturer operations, sources of
ingredients, movements through the supply chain and distribution, etc.
There may be inherently gluten-free foods or ingredients that still do
not meet the definition of ``gluten-free'' due to cross-contact with
gluten that leads to gluten content in the food that is at or above 20
ppm. Conversely, there also may be inherently gluten-free foods that
have some cross-contact with gluten-containing products but are still
able to bear the ``gluten-free'' claim because the presence of gluten
in the food due to cross-contact is less than 20 ppm. Just as we
concluded in the preamble to the 2013 gluten-free food labeling final
rule (78 FR 47154 at 47168), all food bearing a ``gluten-free'' claim,
regardless if they are inherently gluten-free or not, must meet the
definition of ``gluten-free.'' In 2015, we stated in the preamble to
the proposed rule for gluten-free labeling of fermented or hydrolyzed
foods that the specific types of records that would provide adequate
assurance that fermented or hydrolyzed ingredients with a high
likelihood of gluten cross-contact, such as grains and legumes, may
differ from the records that would provide adequate assurance for
ingredients with a lower likelihood of gluten cross-contact, such as
dairy (80 FR 71990 at 71996 through 71998). For example, a manufacturer
of fermented or hydrolyzed foods from non-gluten-containing grains,
legumes, or seeds that are susceptible to cross-contact with gluten-
containing grains bearing the ``gluten-free'' claim may choose to
obtain a CoA from the ingredient suppliers or test the ingredients
before fermentation and maintain records of the test results. A
manufacturer of products bearing the ``gluten-free'' claim made from
inherently gluten-free ingredients, such as milk, or fruit, that have
low probability of cross-contact with gluten-containing grains may be
more likely to use other appropriate verification documentation. Thus,
we decline to modify Sec. 101.91(c)(3) to exclude any group of foods
or ingredients because doing so does not consider the possibility of
cross-contact.
We also decline to define the term ``fermented food'' as a food or
ingredient derived only from a gluten-containing
[[Page 49245]]
grain by fermentation. The final rule is intended to cover all foods
that are fermented or contain fermented ingredients and bear the term
``gluten-free,'' not just those from gluten-containing grains.
Regardless of whether the food that is subjected to fermentation
contains gluten, we cannot exclude the possibility that the food could
be exposed to gluten due to cross-contact. It is important that all
manufacturers who choose to use the ``gluten-free'' claim on their
foods that are fermented or contain fermented ingredients evaluate
their process for potential gluten cross-contact.
As requested by a comment, we are clarifying that the final rule
does not require testing of ingredients. The final rule requires
manufacturers to adequately evaluate their processing for any potential
for gluten cross-contact. Such assessment involves evaluation of each
individual manufacturing process to find out if there is a known or
reasonably foreseeable risk of cross-contact with gluten-containing
grains and maintenance of records to indicate that measures have been
implemented to prevent the introduction of gluten into the food during
the manufacturing process. As noted in the preamble to the 2015
proposed rule, we are aware that some foods and ingredients are more at
risk than others (80 FR 71990 at 71996 through 71998). The manufacturer
is best suited to decide how to adequately evaluate any potential for
gluten cross-contact during its manufacturing process as well as the
measures that should be taken to prevent the introduction of gluten
into the food during that manufacturing process. The final rule
requires that manufacturers of food products covered by the rule make
and keep records providing adequate assurance that: (1) The food is
``gluten-free'' before fermentation or hydrolysis; (2) the manufacturer
has adequately evaluated the potential for cross-contact with gluten
during the manufacturing process; and (3) if necessary, measures are in
place to prevent the introduction of gluten into the food during the
manufacturing process. In some cases, adequate assurance may be
provided through testing the ingredients when there is a scientifically
valid method that can reliably detect the presence of 20 ppm gluten.
Testing should indicate that foods or ingredients contain less than 20
ppm gluten before fermentation or hydrolysis. To help address potential
gluten cross-contact during the manufacturing process, the final rule,
at Sec. 101.91(c)(2) and (3), requires that manufacturers of a
fermented or hydrolyzed product who wish to use a ``gluten-free'' claim
make and keep records that provide adequate assurance that they have
carefully evaluated their processing for any potential for gluten
cross-contact, and where the potential exists, manufacturers have
implemented measures to prevent the introduction of gluten into the
food. Through this process, a manufacturer can assure that the food or
its ingredients comply with Sec. 101.91(a)(3) before fermentation or
hydrolysis. As specified in the preamble to the 2015 proposed rule (80
FR 71990 at 71996 through 71998), the records providing adequate
assurance that the food is ``gluten-free'' before fermentation or
hydrolysis could include records of test results conducted by the
manufacturer or an ingredient supplier, CoA, or other appropriate
verification documentation for the food itself or each of the
ingredients used in the food. We would expect manufacturers of
fermented or hydrolyzed foods that bear the ``gluten-free'' claim, as
part of their routine operations, to test their food or ingredients
with the sufficient frequency to ensure that the gluten level in the
food or in each ingredient is below 20 ppm before fermentation or
hydrolysis. Alternatively, as we noted in the preamble to the 2013
gluten-free food labeling final rule (78 FR 47154 at 47167),
manufacturers, as part of routine operations, may rely on records, such
as CoAs, from their suppliers to determine that each ingredient is
below 20 ppm gluten. Similarly, for ingredients received from outside
suppliers, manufacturers may document a visit to a supplier's facility,
a review of supplier's records, or a review of written documentation
from a supplier to verify the compliance with Sec. 101.91(a)(3) for
these ingredients. We find it is appropriate to allow a manufacturer to
use any means of verification they develop, if the manufacturer can
document that such verification provides adequate assurance that the
ingredients comply with Sec. 101.91(a)(3). We do not specify the types
of records to be kept, so the manufacturer could, for example, create
records regarding the ingredients used or maintain records or CoAs
obtained from a supplier.
As we discussed in the preamble to the 2013 gluten-free food
labeling final rule (78 FR 47154 at 47173), we expect foods bearing the
``gluten-free'' claim to be manufactured using the controls necessary
to minimize cross-contact with all gluten sources to ensure that any
amount of gluten in the food from gluten cross-contact is as low as
possible and that the food has less than 20 ppm gluten. Also, we would
accept information on growing practices and product segregation as
records to meet the requirements of this final rule.
(Comment 2) Several comments expressed concerns regarding some
aspects of the proposed rule as it could relate to enzymes. For
example, some comments stated that commercial enzymes are often
produced by microbes grown on media containing wheat and that these
enzymes are considered to be processing aids when used in other foods
produced by fermentation. The comments said that very little gluten
protein (if transferred to the food by the enzyme) may survive the
fermentation process. Therefore, the comments said these enzymes should
not be covered under the rule. The comments stated that the production
of enzymes includes a bacterial fermentation step, but the enzymes
themselves are not fermented or hydrolyzed. The comments noted that the
final product is purified to remove extraneous materials and claimed
that very small amounts of their enzyme products are used in food
processing and, therefore, would not present a health risk to patients
with celiac disease. Finally, the comments explained that wheat is not
used by the enzymes that form the final product and the enzymes do not
contain gluten; thus, according to the comments, the enzymes should not
be classified as fermented or hydrolyzed, and we should exempt the
enzymes from the rule and allow foods produced with the use of such
enzymes to bear a ``gluten-free'' claim if the foods meet the ``gluten-
free'' definition under Sec. 101.91(a)(3).
(Response 2) The issue of purity and potential carry-over of growth
media containing gluten is a valid concern for both the manufacturers
and consumers with celiac disease. Wheat may be present in any carried-
over nutrient media used to grow the microbes, and the gluten in the
media may be subjected to proteolytic digestion (hydrolysis) making its
quantity and biological activity hard to confirm using currently
available technology. Further, it is likely that these properties will
vary with the specific production process (e.g., type of microbe grown,
temperature, incubation period, etc.). We agree that the enzymes
produced in this manner are not themselves fermented; however, the
gluten that may possibly be present in the enzyme may be hydrolyzed due
to fermentation. An important consideration is the amount of potential
carryover and how much of the enzyme ingredient is used in the
production of the final food product. Because these factors may vary
[[Page 49246]]
considerably, we decline to exempt enzymes from the rule.
Finally, we disagree with the comments' assertions that, because
wheat is not used by the enzymes that form the final product, the
enzymes do not contain gluten. Section 101.91(a)(3) requires some means
of demonstrating that the final product has been processed to remove
gluten to a level below 20 ppm. During the enzyme production process,
the microbes make use of wheat in the nutrient medium, and any gluten
present, because of the carry-over described in the preceding
paragraph, may have undergone alterations, such as protein
fragmentation and deamidation, during the bacterial fermentation step.
We do not know how these changes affect the immunopathogenicity and
other properties of gluten, and it is not clear whether the means of
measuring compliance with the 2013 gluten-free food labeling final rule
for intact gluten would be sufficient to safeguard consumers with
celiac disease. Thus, until this is known, the final rule is needed to
help ensure that individuals with celiac disease are not misled and
receive truthful and accurate information with respect to fermented or
hydrolyzed foods labeled as ``gluten-free.''
(Comment 3) One comment regarding the effects of various processing
and treatment technologies noted that it was important to distinguish
between those that actually remove gluten and those that modify or
cleave the protein molecules without actually removing anything from
the food or ingredient. The comment provided an example of production
of wheat starch that involves a step in which a protein (gluten)-
enriched fraction is physically separated from a protein depleted
(potentially gluten-free) starch fraction. In this case, gluten has
been removed. When a food or ingredient is treated by fermentation or
hydrolysis, it is only possible to state that the gluten has been
modified, not removed.
(Response 3) We agree that there is a difference between physical
removal and modification (processing) of gluten to generate a product
that does not contain any immunopathogenic elements of concern to
consumers with celiac disease. When physically removing the gluten, the
question is whether all of the gluten has been removed so that there is
no trace left that might cause an adverse health event. Modification of
the gluten is not definitive unless it is possible to demonstrate that
all of the modified gluten or its protein components are no longer
harmful for individuals with celiac disease.
2. Innovation in Developing Methods for Fermented, Hydrolyzed, or
Distilled Foods
(Comment 4) A few comments stated that a valid method exists to
quantify gluten in a product that has been fermented or hydrolyzed,
like beer, and pointed to the R5 Competitive ELISA test with
inactivated protease enzyme.
(Response 4) When compliance with Sec. 101.91(b) is based on an
analysis of the food, FDA will use a scientifically valid method that
can reliably detect the presence of 20 ppm gluten in a variety of food
matrices, including both raw, cooked, or baked products (Sec.
101.191(c)). As stated in the 2011 notice and the 2013 gluten-free food
labeling final rule, a scientifically valid method for purposes of
substantiating a ``gluten-free'' claim for food matrices where formally
validated methods (e.g., that underwent a multi-laboratory performance
evaluation) do not exist is one that is accurate, precise, and specific
for its intended purpose and where the results of the method evaluation
are published in the peer-reviewed scientific literature. In other
words, a scientifically valid test is one that consistently and
reliably does what it is intended to do (76 FR 46671 at 46673; 78 FR
47154 at 47165). The R5 Competitive ELISA test has potential as a
quantitative method, and we acknowledge that, under the appropriate
test conditions, the R5 Competitive ELISA can generate reproducible
results. The commercial R5 Competitive ELISA marketed for the detection
of hydrolyzed (or fermented) gluten has, by design, an advantage over
sandwich ELISA-based methods by not requiring the presence of two
antigenic epitopes (antibody binding sites) to detect the presence of
gluten peptides. Further, because the immunopathogenesis associated
with celiac disease only requires a single immunopathogenic element,
the R5 Competitive ELISA is theoretically more appropriate as an assay.
However, as currently designed, the R5 Competitive ELISA method is
not suitable for the detection and quantification of gluten in any
fermented or hydrolyzed food (e.g., beer, yogurt). The lack of
appropriate reference standards for the detection and quantification of
gluten subjected to fermentation or proteolysis (hydrolysis) makes the
results generated by the R5 Competitive ELISA difficult, if not
impossible, to interpret. As currently supplied, the calibration
standard in the R5 Competitive ELISA is allowed to proceed for a
specified amount of time at a specific temperature. If the hydrolytic
conditions (time, temperature, or composition under which the
hydrolysis is occurring) associated with the production of the sample
being analyzed were different from those used to make the calibration
standards, the peptide profile is likely to be different, and the assay
is unlikely to generate accurate results. The Association of Official
Analytic Chemists Official Methods of Analysis (AOAC OMA) First Action
award to the R5 Competitive ELISA stated that the hydrolyzed gluten
being used as a calibration standard may not be suitable, and users
should establish their own standards before relying on the calibration
standard (Ref. 3). Specifically, minor fluctuations in temperature and
time, as well as the specifics of the proteolysis, could result in a
different range of peptides, making the calibration standards not
suitable.
Further, it is not known how to interpret the immunopathogenicity
based on the amount and profile of gluten peptides detected. The
threshold of 20 ppm gluten was based on studies examining the
immunopathogenicity of intact gluten. Whether the biological activity
on a per mg basis is the same for gluten peptides, as was measured with
intact proteins, is unknown; the answer may depend on the peptide
profile.
Thus, we have concerns regarding the use of the R5 Competitive
ELISA in the detection of gluten in fermented or hydrolyzed foods or
ingredients because of the challenge in demonstrating that it is
suitable for the intended purpose of interpreting the
immunopathogenicity based on the amount and profile of gluten peptides
detected and whether the method performs reliably (i.e., is a
scientifically valid method). While the method may perform reproducibly
as indicated by the American Association of Cereal Chemist
International (AACCI) validation (Ref. 4), it does not mean that the
method is suitable for the intended purpose of detecting and
quantifying, with sufficient accuracy, the gluten protein content in
fermented and hydrolyzed foods, or assessing the immunopahogenicity or
equivalent amount of intact gluten proteins.
Finally, the procedure of adding a controlled amount of an
artificially prepared hydrolysate to food as required by the testing
protocol (a process called ``spiking'') may give an inaccurate reading
because it does not reflect the assay's ability to detect gluten that
has been added to the food before processing and hydrolyzed during
production. For this reason, it is
[[Page 49247]]
important that, whenever possible, methods be validated using gluten
that is added to the food before processing. The inability to detect
any gluten using the R5 Competitive ELISA (below the limit of
detection) is not an indication of complete elimination or even a
reduction of gluten. Another complexity is that not all the
immunopathogenic sequences of gluten have been identified. Further, the
R5 antibody does not recognize all immunopathogenic sequences (e.g.,
glutenin-derived) and, therefore, gluten could be present in a form
that is not detectable (Ref. 5).
(Comment 5) One comment stated that the proposed rule would require
gluten to be measured using scientifically valid methods. The comment
would have us revise the rule to address the fact that there are many
different test methods and that they vary in their ability to provide
accurate and precise data. The comment suggested that, instead of
requiring that testing labs merely use ``scientifically valid'' test
methods, we require that the methods are fully validated, thereby
establishing performance reliability (the consistency or
reproducibility of the test).
(Response 5) The ideal test method for detecting and quantifying
the gluten content of feremented or hydrolyzed foods is a
scientifically valid method that is suitable for the intended purpose
and has been extensively, preferably multi-laboratory validated.
However, multi-laboratory validation is sometimes conducted for
conditions that are not suitable for the intended purpose (not
scientifically valid). For example, in the R5 Competitive ELISA, which
has undergone multi-laboratory validation for use in the quantitative
analysis of fermented or hydrolyzed gluten, the calibration standard
often does not represent the peptide repertoire being measured and,
thereby, is not suitable for fermented or hydrolyzed foods or
ingredients. Further, validation should focus on realistic samples.
Instead, the R5 Competitive ELISA validation employed a calibration
standard to which a controlled amount of substance, as required by
protocol, was added into several samples; as such, the recoveries and
performance of the assay were not reflective of the analysis of
realistic samples. The R5 Competitive ELISA is not the only example of
a method that has been promoted for use in an analysis of gluten in
fermented or hydrolyzed foods, but it is mentioned here because it has
been promoted for use in the quantitative analysis of fermented or
hydrolyzed gluten. Although an AOAC Official Method is often a good
indicator of reliability (not necessarily `suitability for purpose'
beyond the specifics described in the validation report), there are
other organizations, such as the American Society for Testing and
Materials (ASTM), that may develop methods that perform reliably and
may be appropriate for testing gluten in fermented or hydrolyzed foods.
Other governmental agencies and industry may adopt their own
procedures for testing gluten in hydrolyzed and fermented foods as
well. The focus should be on using the most appropriate, scientifically
valid method that meets the manufacturer's needs. Realizing
insufficiencies of existing validation methods, we established our own
validation protocols. Our validation protocols focus on the detection
and quantification of analytes under realistic conditions (such as
using a standard that has been spiked before any food processing
instead of simply spiking the standard into the final food product).
Once a method has been validated, the method can only be used for a
novel food following evaluation and validation of the method
performance with the specific food matrix.
(Comment 6) Several comments stated that the proposed rule does not
offer flexibility for scientific innovation and, therefore,
unintentionally prevents fermented and hydrolyzed foods from benefiting
from scientific advancements that are very likely to be achieved. One
comment stated that the proposed rule is overly restrictive, shows
disregard to competition and innovation, and threatens to stifle the
marketplace because it fails to account for new and emerging
technologies and scientific developments in this area. Other comments
asserted that the rule will limit options for those suffering from
gluten-related disorders.
(Response 6) As with all detection methodology, we support efforts
to resolve the uncertainty issues associated with quantifying gluten
fragments and interpreting results in terms of intact gluten. The
preamble to the 2013 gluten-free food labeling final rule (78 FR 47154
at 47169) and this final rule reflect our support in encouraging
innovation in how gluten-free products are produced and the development
of new analytical methods for detecting the gluten content of foods.
Other than our discussion of distillation, where testing for the
absence of protein indicates compliance with the use of the term
``gluten-free,'' we deliberately did not specify analytical methods
that should be used. We did this because we believe that specifying
analytical methods would unnecessarily limit flexibility and possibly
deter the development of new and better analytical methods as well as
methods for gluten removal. In the preamble to the 2013 gluten-free
food labeling final rule (78 FR 47154 at 47169), we stated that we were
not specifying analytical methods in the final rule even though we had
included a description of two analytical methods that met our needs for
the analysis of intact gluten in the 2011 notice that reopened the
comment period for the proposed rule for gluten-free food labeling of
foods (76 FR 46671 at 46672). In the 2011 notice, we described the
methods along with references explaining how the two methods were
suitable-for-purpose and were validated. The information in the
preamble to the 2013 gluten-free food labeling final rule provided
extensive discussion about why we were not specifying analytical
methods in order to support the development of new and better
technologies and also demonstrate flexibility for foods that are not
fermented or hydrolyzed by allowing stakeholders to use the methods
most appropriate to fit their needs (78 FR 47154 at 47169).
More importantly, we have written the final rule in a manner that,
once we identify that a scientifically valid method, pursuant to Sec.
101.91(c)(1), has been developed that can accurately detect and
quantify gluten in some or all fermented or hydrolyzed foods or
ingredients, Sec. 101.91(c)(2)-(c)(4) would no longer be applicable
for those foods, and it would no longer be necessary for the
manufacturer of foods bearing the ``gluten-free'' claim to make and
keep the records required under Sec. 101.91(c)(2)-(c)(4) demonstrating
adequate assurance that the food meets the ``gluten-free'' definition
before fermentation or hydrolysis. Should any new scientifically valid
methods be developed that can accurately detect and quantify gluten in
fermented and hydrolyzed foods, FDA would determine compliance in
accordance with Sec. 101.91(c)(1). (On our own initiative, we have
revised Sec. 101.91(c)(1) to state that the scientifically valid
method is one that can ``reliably detect and quantify'' the presence of
20 ppm gluten. We added the words ``and quantify'' to clarify that the
scientifically valid method needs to do more than detect the presence
of gluten.) In addition, should any new scientifically valid methods be
developed for fermented or hydrolyzed foods, we expect that we would
identify the existence of such methods through guidance or other
appropriate means.
[[Page 49248]]
Therefore, we disagree with the assertion that the final rule is overly
restrictive, adversely affects competition or innovation, or fails to
account for emerging technologies.
(Comment 7) One comment asked us to give insight regarding which
analytical methods might be of greater utility for verifying absence of
protein in distilled foods and ingredients.
(Response 7) We decline to discuss in detail the pros and cons of
the various analytical methods available for verifying the absence of
protein in distilled food and ingredients because the best method may
depend on factors such as food matrix, the experience of the analyst,
the business decision of the company, etc. Additionally, a list of
methods may be misinterpreted as indicating that we consider other
approaches that are not included on the list to be unacceptable or of
comparatively less value or usefulness.
3. Distilled Food
(Comment 8) One comment stated that FDA claimed that there is no
proof that gluten does not volatilize during the distillation process
because the temperatures are not high enough to allow gluten to pass
through a still. The comment went on to state that, rather than banning
a ``gluten-free'' claim on any product that had not been tested for
gluten, FDA should rely on existing science that proves that gluten
does not pass through a distillation still and, therefore, would not
end up in a distilled product. The comment said that testing every
batch is a hardship on small craft and farm distillers and prevents
marketing of these kind of products to those with gluten intolerance.
The comment also said that we should commission a scientific study to
confirm that gluten may be present in distilled spirits or that gluten
does not pass through a still and, therefore, all distilled spirits do
not contain gluten.
(Response 8) The comment may have misunderstood our position. We
did not claim that there is no proof that gluten does not volatilize
during the distillation process because the temperatures are not high
enough to allow gluten to pass through a still. If good manufacturing
practices are followed, the process of distillation must remove all
protein (and thus gluten), regardless if the product has been distilled
from gluten-containing grains. As discussed further in Response 9,
distillation is considered a process to remove gluten and it is
unlikely that residual gluten may be present in the final distilled
products. Transfer of gluten into the distillate would only be expected
to occur under poor manufacturing practices in which the initial
material is splashing into the distillate due to poor design of the
still. Protein testing can be done to confirm that protein (and thus
gluten) is absent in the distilled product. We note that testing of
each batch is not required under existing regulations, and this rule
specifies the methods we will use to verify compliance for distilled
foods in Sec. 101.91(c)(5). In addition, we note that any ingredients
(such as flavors) added to the distilled product would need to comply
with our regulations defining ``gluten-free'' in Sec. 101.91(a) for
the finished product labeling to bear the gluten-free claim.
(Comment 9) A few comments opposed different requirements for
distilled foods because, according to the comments, distilled foods
have caused reactions in some people and, therefore, are not safe. The
comments stated that the exception for distilled foods is in direct
conflict with the gluten-free food labeling rule and creates an uneven
playing field within the overall alcoholic beverages category. The
comments pointed out that malt beverages or other products that have
undergone a process to remove or reduce gluten content are not treated
the same as distilled spirits.
One comment suggested a tiered labeling system for distilled foods
with varying labels (``Gluten-free,'' ``gluten-free'' with a
disclaimer, ``gluten-reduced,'' no gluten claim allowed) that allows
``gluten-free'' labeling when testing is possible with the caveat that
if the starting material was a gluten-containing grain, a disclaimer is
used to disclose this fact. The comment claimed that this tiered
labeling standard would provide full disclosure to the consumer, place
the burden on industry to provide accurate labeling, and be
transparent.
(Response 9) As we explained in the preamble to the proposed rule
(80 FR 71990 at 71995, 71999), while creating distilled vinegar does
involve fermentation, the process of distillation heats a liquid, which
vaporizes components with lower boiling points and separates them from
components with higher boiling points. The remaining compounds, whose
boiling points are too high to undergo vaporization, are left behind.
If distillation is done properly, the process removes gluten because
gluten does not vaporize. Therefore, there should not be any gluten
remaining in the final distilled product. For this reason, a distilled
product labeling may bear a ``gluten-free'' claim and should be safe
for people with celiac disease to consume.
We also disagree that the regulations for distilled foods or
ingredients is in direct conflict with our regulations defining
``gluten-free.'' Our regulations permit ingredients derived from a
gluten-containing grain that has been processed to remove gluten if the
use of that ingredient does not result in the presence of 20 ppm or
more gluten in the food (Sec. 101.91(a)(3)(i)(A)(3)).
We are aware that the process of distillation is capable of
separating gluten and other proteins from the remaining compounds and,
therefore, we make this distinction for foods or ingredients that are
distilled. Scientifically valid methods for protein testing can
determine if a product is free of protein and, therefore, also free of
gluten. Thus, we will evaluate compliance by verifying the absence of
protein in the distilled component using scientifically valid
analytical methods that can reliably detect the presence or absence of
protein or protein fragments in the food. Furthermore, we note that
malt beverages, as defined under the Federal Alcohol Administration Act
(FAA Act) (27 U.S.C. 211(a)(7)), do not undergo distillation and,
therefore, would not be subject to Sec. 101.91(c)(5).
As for the comment regarding a tiered labeling system, to be
consistent with Sec. 101.91, which defines the term ``gluten-free,''
we decline to introduce a tiered labeling system along with a
disclaimer because Sec. 101.91(b)(2) provides for the use of the label
claims ``gluten-free,'' ``no gluten,'' ``free of gluten,'' or ``without
gluten'' if the product meets the definition under Sec. 101.91(a)(3).
Use of any of these terms on products that were made from gluten-
containing grains would not meet the definition of ``gluten-free'' in
Sec. 101.91(a)(3) and would, therefore, misbrand the products unless
the ingredients used to formulate the food have been processed to
remove gluten and the final food product contains less than 20 ppm of
gluten. We note that this rule does not prohibit other truthful and not
misleading labeling statements about the presence or absence of gluten
in food products that do not meet a ``gluten-free'' definition,
provided the statements do not expressly or implicitly suggest that the
food meets FDA's ``gluten-free'' definition.
(Comment 10) One comment stated that we should revise the rule to
distinguish between distilled vinegar made from raw material naturally
free from gluten and vinegar made from raw material containing gluten.
The comment recommended that if the original feedstock is ``gluten-
free,'' then no further testing is needed. The comment pointed out that
distilled
[[Page 49249]]
vinegar is made from distilled ethanol which is further fermented into
vinegar by bacteria. Distilled ethanol is generally produced from non-
gluten-containing raw material such as corn, beet or sugar cane but in
some cases, also gluten-containing cereals. Vinegar itself is not
distilled; only the main raw material to make the vinegar is distilled.
Therefore, according to the comment, proteins and/or protein fragments
may be present due to the use of yeast or yeast extract in the
fermentation of distilled vinegar.
Other comments asked us how we plan to distinguish proteins or
protein fragments that may originate from the ethanol feedstock from
those proteins and protein fragments that may originate from the
ethanol fermentation process. The comments stated that such a
distinction for any protein detected is important.
(Response 10) As we explained previously in the preamble to the
proposed rule (80 FR 71990 at 71995, 71999), distillation is a process
capable of separating gluten and other proteins from the remaining
compounds and, therefore, we make this distinction for foods or
ingredients that are distilled. Due to the distillation process, no
protein fragments should be in the ethanol feedstock. Scientifically
valid methods for protein testing can determine if a product is free of
protein and, therefore, also free of gluten. Only those vinegars made
from distilled ethanol that are further processed in a manner to avoid
the introduction of gluten can be considered ``gluten-free.'' As for
the possible introduction of gluten from those proteins and protein
fragments that may originate from the ethanol fermentation process, as
with any product, it is the manufacturer's responsibility to implement
measures preventing the introduction of gluten into the food elsewhere
in the manufacturing process for an ingredient made ``gluten-free'' by
distillation. Further, the manufacturer could request from their
supplier that the raw materials, such as bacteria or yeast used in the
fermentation of distilled vinegar, be ``gluten-free.'' One way this can
be accomplished is by avoiding the use of bacteria grown on any gluten-
containing source material or by using appropriate testing to confirm
that the material (bacteria) are ``gluten-free.'' Thus, the vinegar
manufacturer would have assurance that the distilled ethanol was used
in a manner that prevented the introduction of gluten into the food
during the manufacturing process.
Scientifically valid analytical methods are readily available to
detect the presence or absence of protein and protein fragments (and
thus gluten) in distilled foods. Therefore, as indicated in Sec.
101.91(c)(5) of this final rule, we will evaluate compliance with Sec.
101.91(b) by verifying the absence of protein in the distilled
component using scientifically valid analytical methods that can
reliably detect the presence or absence of protein or protein fragments
in the food.
4. Different Compliance Standard
(Comment 11) Some comments stated that the rule concludes that
fermented or hydrolyzed foods should be subject to a different labeling
compliance standard than other foods bearing a ``gluten-free'' claim
based upon the assumption that no scientifically valid method will be
developed to accurately detect the presence of gluten in these food
products.
(Response 11) There is research underway within FDA and elsewhere
to develop methods to accurately detect and quantify the presence of
gluten in fermented or hydrolyzed foods. However, as we noted in the
proposed rule (80 FR 71990 at 71991), although test methods for the
detection of gluten fragments in fermented or hydrolyzed foods have
advanced, there is still uncertainty in interpreting the results. The
currently available test methods are not capable of producing results
on a quantitative basis that equate to an equivalent amount of intact
gluten, and thus, we are making available alternate means by which
these kinds of foods can comply with Sec. 101.91. Once we have
identified a scientifically valid method, it would no longer be
necessary for the manufacturer of foods bearing the ``gluten-free''
claim to make and keep the records required under Sec. 101.91(c)(2)-
(c)(4), and FDA would determine compliance in accordance with Sec.
101.91(c)(1). If or when a scientifically valid method to detect and
quantify the presence of gluten in fermented or hydrolyzed foods become
available, we will identify this change through a guidance document or
other appropriate means. In addition, FDA may consider changing our
regulations if warranted.
(Comment 12) Several comments questioned whether fermented or
hydrolyzed foods should be subject to a different compliance standard
than other foods bearing a ``gluten-free'' claim when there is a high
probability that a scientifically valid method will be developed in the
very near future to accurately detect the presence of gluten in such
foods. The comments suggested that we remove the reference to any
particular food that is distilled, fermented, or hydrolyzed in the
wording of proposed Sec. 101.91(c)(2) through (c)(5). This would mean
that the labeling requirements would apply equally to all food
categories for which a scientifically valid method is not available to
confirm compliance with the 20 ppm gluten threshold. The comments said
this would provide FDA with the necessary compliance authority to
impose a higher standard on certain foods where we determine that a
valid scientific method does not currently exist. Later, when a
scientifically valid analytical method is established, no regulatory
amendment process would be required. The comments further explained
that the proposed language does not offer any flexibility for
scientific innovation in this area and unintentionally prevents this
group of foods from ever benefiting from scientific advancements that
are likely to be achieved.
(Response 12) When we developed the proposed rule, there were no
scientifically valid methods for the purposes of analyzing fermented or
hydrolyzed foods to determine compliance with Sec. 101.91. Because,
currently, there are no analytical methods to reliably detect and
quantify gluten in fermented or hydrolyzed food nor methods to equate
test results in terms of intact gluten, we will evaluate compliance of
these foods that bear a ``gluten-free'' labeling claim with the 2013
gluten-free food labeling final rule based on records that provide
adequate assurance that the foods are ``gluten-free'' before
fermentation or hydrolysis. Fermented or hydrolyzed foods are subject
to the same labeling compliance standards as any other food that would
bear a ``gluten-free'' claim. This final rule describes how
manufacturers of fermented or hydrolyzed foods or distilled foods would
be able to demonstrate compliance and how FDA will evaluate compliance.
For this reason, we decline to remove reference to distilled foods and
fermented or hydrolyzed foods from Sec. 101.91(c)(2) through (c)(5).
Further, as we noted in Response 6, if or when a scientifically valid
method for fermented or hydrolyzed foods becomes available, FDA will
identify such a method through a guidance document or other appropriate
means. Once FDA identifies such a method, it would no longer be
necessary for the manufacturer of foods bearing the ``gluten-free''
claim to make and keep the records required under Sec. 101.91(c)(2)
though (c)(4), and FDA would determine compliance with the ``gluten
free'' labeling requirements under Sec. 101.91(c)(1).
(Comment 13) One comment stated that the proposed rule appears to
[[Page 49250]]
impose a stricter requirement on electronic records related to the
gluten-free voluntary labeling standard than the requirements for other
food safety records under other regualtions. For example, the comment
states that section II.C. of the proposed rule (80 FR 71990 at 71998
through 71999) indicates that electronic records, including electronic
signatures, established or maintained to meet the requirements of this
rule would be subject to the electronic records and electronic
signatures requirements in part 11 (21 CFR part 11). However, the
comment states that Sec. 117.305(g), FDA's regulation concerning
Current Good Manufacturing Practice, Hazard Analysis, and Risk-Based
Preventive Controls for Human Food, establishes that electronic records
established or maintained to meet the requirements of part 117 and that
meet the definition of electronic records in Sec. 11.3(b)(6), are
exempt from the requirements of part 11.
(Response 13) Although the proposed rule indicated that electronic
records would need to comply with part 11, we also note that the use of
electronic records is voluntary and thus, a paper record system could
be used to comply with the proposed recordkeeping requirements. This
would give manufacturers the maximum flexibility to use whatever
recordkeeping system they find most appropriate (80 FR 71999).
The final rule would allow these records to be kept as original
records, as true copies or as electronic records, and manufacturers
would have to make the records available to us for inspection and
copying, upon request, during an inspection. Records that can be
immediately retrieved from another location by electronic means are
considered reasonably accessible. Compliance with FDA's regulation
concerning Current Good Manufacturing Practice, Hazard Analysis, and
Risk-Based Preventive Controls for Human Food in 21 CFR part 117 has no
bearing on this rule.
(Comment 14) One comment said that, in the preamble to the proposed
rule, but not in the proposed codified language, FDA recognizes that
there is a significant difference between fermented or hydrolyzed foods
produced from gluten-containing grains and those that are not.
According to the comment, proposed Sec. 101.91(c)(2) would require the
manufacturer of such foods bearing the claim to make and keep records
demonstrating adequate assurance that the fermented or hydrolyzed
ingredients are ``gluten-free.'' The comment said that the preamble to
the proposed rule stated that ``the types of records that would provide
adequate assurance for ingredients with a high likelihood of gluten
cross-contact, such as grains and legumes, may vary from those expected
for ingredients with a lower likelihood of gluten cross-contact, such
as dairy.'' The comment suggested that this can be interpreted as
imposing a greater recordkeeping requirement on the ``low likelihood''
foods than is required in part 117, ``Current Good Manufacturing
Practice, Hazard Analysis, and Risk-Based Preventive Controls for Human
Food'' (21 CFR part 117) for food safety hazard analysis. In
particular, the comment said that, in Sec. 117.130(b)(1),
manufacturers only must address hazards that are ``known or reasonably
likely.'' The comment said that it would be appropriate to only require
records in cases where the potential presence of gluten or gluten-
containing grains is ``known or reasonably likely.'' The comment stated
that manufacturers should be required to document the information and
process used to reach this conclusion but should not be subject to
further recordkeeping requirements.
(Response 14) The comment asked that we only require records in
cases where the potential presence of gluten or gluten-containing
grains is ``known or reasonably likely.'' While the ``known or
reasonably likely'' standard is established in part 117 for food safety
hazard analysis, this final rule was specifically developed to
establish the requirements for the voluntary use of the ``gluten-free''
claim that allows consumers to practice dietary avoidance and benefits
individuals suffering from celiac disease. Although we acknowledge that
there is a difference in the likelihood of gluten cross-contact in some
fermented or hydrolyzed foods, because there is no scientifically valid
method to quantify the gluten protein content in fermented or
hydrolyzed foods, manufacturers who wish to produce and label such
foods as ``gluten-free'' still need to make and keep records, as
described in the new requirements of Sec. 101.91(c), to provide
adequate assurance of the type of ingredient used is ``gluten-free''
before fermentation or hydrolysis and to address the potential for
cross-contact with gluten-containing grains or ingredients. The records
for different foods can have different levels of detail needed to
demonstrate compliance. As we have noted in section III.A. and
elsewhere in this document, the results of current gluten test methods
for fermented and hydrolyzed foods do not provide accurate quantitive
results sufficient to be suitable for use with fermented or hydrolyzed
foods. Thus, to evaluate compliance of such fermented and hydrolyzed
foods that bear a ``gluten-free'' claim, we need to rely on records
made and kept by the manufacturer providing adequate assurance that the
food is ``gluten-free'' in compliance with Sec. 101.91(a)(3) before
fermentation or hydrolysis. In addition, this rule requires the
manufacturer of fermented or hydrolyzed foods bearing the ``gluten-
free'' claim to document that it has adequately evaluated the potential
for gluten cross-contact and, if identified, implemented measures to
prevent the introduction of gluten into the food during the
manufacturing process.
It is, therefore, appropriate and reasonable to impose the
recordkeeping requirement established under Sec. 101.91(c)(4) in this
final rule for fermented or hydrolyzed foods bearing a ``gluten-free''
claim to substantiate a firm's compliance with Sec. 101.91(a).
Therefore, we decline to change the rule as suggested by the comment
and have finalized Sec. 101.91(c)(4) without change.
5. ``Gluten-Free'' Labeling of Beer
The Treasury Department's Alcohol and Tobacco Tax and Trade Bureau
(TTB) is responsible for the issuance and enforcement of regulations
with respect to the labeling of beers that are malt beverages under the
FAA Act. Certain other beers that do not meet the definition of a malt
beverage under the FAA Act (27 U.S.C. 211(a)(7)) are subject to FDA's
labeling requirements. Beer manufacturers whose beers are subject to
FDA's labeling requirements and do not meet the ``gluten-free''
definition are not precluded from using other statements on the label,
such as a gluten statement consistent with the TTB Revised Interim
Policy on Gluten Content Statements in the Labeling and Advertising of
Wine, Distilled Spirits, and Malt Beverages, about processing of beers
to reduce gluten (Ref. 6). However, such statements must be truthful
and not misleading in accordance with our general labeling provisions
in sections 403(a)(1) and 201(n) of the FD&C Act.
In the preamble to the 2013 gluten-free food labeling final rule
(78 FR 47154 at 47166), we said that, under limited circumstances, we
would exercise enforcement discretion with respect to the requirements
for ``gluten-free'' labeling for FDA-regulated beers that already made
a ``gluten-free'' claim before the rule was published and that were:
(1) Made from a non-gluten-containing grain; or (2) made from a gluten-
containing grain, where the beer
[[Page 49251]]
had been subject to processing that the manufacturer had determined
would remove gluten. We said that the enforcement discretion pertained
only to those beers subject to FDA's labeling requirements that made a
``gluten-free'' claim as of August 5, 2013, pending completion of the
rulemaking process with respect to fermented or hydrolyzed products. We
also said that any beer manufacturer that wanted to make a new
``gluten-free'' claims should contact FDA regarding the possible
expansion of our consideration for the exercise of enforcement
discretion related to such labeling. With the publication of this final
rule, we complete the gluten-free labeling rulemaking and the
enforcement discretion described in the preamble to the 2013 gluten-
free food labeling final rule (78 FR 47154 at 47166) is no longer
valid.
On February 11, 2014, TTB issued a revised interim policy on gluten
content statements in the labeling and advertising of beverages or
beers it regulates. The ``Revised Interim Policy on Gluten Content
Statements in the Labeling and Advertising of Wines, Distilled Spirits,
and Malt Beverages'' allows the use of the following qualifying
statement to inform consumers: ``Product fermented from grains
containing gluten and [processed or treated or crafted] to remove
gluten. The gluten content of this product cannot be verified, and this
product may contain gluten,'' or ``This product was distilled from
grains containing gluten, which removed some or all of the gluten. The
gluten content of this product cannot be verified, and this product may
contain gluten.'' (Ref. 6).
We stated in the preamble to the proposed rule (80 FR 71990 at
71994) that, as with other foods, beers made using a gluten-containing
grain do not meet the ``gluten-free'' definition. Thus, beers made from
gluten-containing grains cannot bear a ``gluten-free'' claim. However,
as with other foods, if the gluten-containing grain has been processed
to remove gluten (e.g., wheat starch) in accordance with the provisions
in the ``gluten-free'' definition before making beer, the beer may be
eligible to make the claim.
As far as the claims that beer made from gluten-containing grains
can be processed to remove gluten, we are not aware of any
scientifically valid way to evaluate such a claim, and there is
inadequate evidence concerning the effectiveness of gluten removal
processes. We acknowledge that gluten can be at least partially broken
down by several processes, including fermentation. However, as we
explain in section III.A. of this rule, the presence or absence of
gluten broken down in this way cannot be reliably detected with
sandwich ELISA-based methods.
In the preamble to the proposed rule (80 FR 71990 at 71994), we
requested comments to learn more about the efficacy of competitive
ELISA-based methods, given the beer industry's practice of adding
enzymes to the beer to prevent the problem of cloudiness or ``haze.''
The enzyme hydrolyzes or breaks down gluten proteins at proline
residues. Thus, using these haze control enzymes may generate peptides
that are not detectable using the commercially available competitive
ELISA-based methods that rely on the presence of proline in the
epitopes. As we noted in the preamble to the proposed rule (80 FR 71990
at 71995), it is uncertain that cleavage at proline residues eliminates
the concern for people with celiac disease because there may be
immunopathogenic protein fragments still present. In other words, we do
not know whether the protein fragments can trigger a reaction in people
with celiac disease.
In the preamble to the proposed rule, we requested comment,
including scientific research, regarding whether beer derived from
gluten-containing grains that may still contain protein fragments from
gluten can be shown by scientifically valid analytic methods to equate
to intact gluten on a quantitative basis (80 FR 71990 at 71995). We
also were interested in scientific research regarding how we can use
such test methods to determine whether beer derived from gluten-
containing grains contains the equivalent of less than 20 ppm intact
gluten proteins, including any data and information regarding
quantification of gluten fragments and determining appropriate
calibration or reference standards. We also invited comment, including
data and any information on scientific research and methods, to
determine if a specific enzymatic treatment of beer derived from
gluten-containing grains can modify proteins or protein fragments such
that they are present at levels equivalent to less than 20 ppm intact
gluten proteins (80 FR 71990 at 71995).
We received several comments related to these specific questions as
well as some other beer-related topics.
(Comment 15) Many comments opposed the use of the terms ``made to
remove gluten,'' ``crafted to remove gluten,'' and other similar such
terms on beer labels. The comments stated that such terms are not the
same as ``gluten-free'' and that consumers may think they are the same,
especially because these products are often marketed as ``gluten-
free.'' Other comments stated that ``gluten-free'' was not the same as
``gluten-reduced,'' and that products treated to remove gluten should
be clearly differentiated from those that are inherently gluten-free.
(Response 15) Our regulations at Sec. 101.91 seek to eliminate
confusing and potentially misleading language that might hinder people
with celiac disease from properly identifying food safe for
consumption. In the preamble to the 2013 gluten-free food labeling
final rule (78 FR 47154 at 47164), we explained that, under Sec.
101.91(b)(2), a food that bears the claim ``no gluten,'' ``free of
gluten,'' or ``without gluten'' in its labeling and fails to meet the
requirements for a ``gluten-free'' claim will be deemed to be
misbranded.
Based upon comments that we received during a public meeting on
August 19, 2005, to discuss the topic of gluten-free food labeling and
comments that were submitted in writing to the related FDA Docket No.
FDA-2005-N-0404 (formerly 2005N-0279), we believe that a uniform
definition of the term ``gluten-free'' prevents confusion and
uncertainty among both consumers and food manufacturers about what this
food labeling claim means. Therefore, we have not defined the terms
``gluten-reduced,'' ``crafted to remove gluten,'' or ``made to remove
gluten,'' and we do not consider those terms to be equivalent to
``gluten-free.'' Although some products may be labeled with these terms
as long as the label is truthful and not misleading (e.g., so as to not
imply that they are gluten-free), we reiterate that consumers with
celiac disease should rely only on the terms specified in Sec.
101.91(b)(2) to indicate that a food is ``gluten-free'' or safe for
them to consume.
This final rule does not change the definition of ``gluten-free,''
but only adds compliance requirements for hydrolyzed, fermented, or
distilled foods.
(Comment 16) Several comments stated that it would be appropriate
for beers made with gluten-containing grains to be labeled as ``crafted
to remove gluten,'' along with a statement that ``the beer is fermented
from grains containing gluten and crafted to remove gluten.'' The
comments stated that the gluten content of the beer cannot be verified
and that a statement that the beer may contain gluten is truthful,
accurate, and not misleading and provides the consumer with adequate
information to make a purchase decision. The comments said that our
proposed rule is too narrow in focus and that TTB's Policy authorizing
qualified ``crafted to remove gluten'' claims for fermented alcohol
beverages made with
[[Page 49252]]
gluten-containing grain ingredients is appropriate. The comments said
that our proposal fails to incorporate TTB's Policy requirements or
distinguish between the claims that are subject to FDA's gluten-free
requirements from TTB's qualified ``crafted to remove gluten'' claim.
The comments strongly urged FDA to adopt the TTB Policy authorizing
qualified ``crafted to remove gluten'' claims.
(Response 16) As we have noted previously, the statutory directive
for this rule was to define the term ``gluten-free,'' and this
rulemaking, like the 2013 gluten-free food labeling final rule, is
intended to implement that statutory directive. The intent in this
rulemaking is to provide an alternative for showing compliance with the
``gluten free'' definition in Sec. 101.91(a)(3) because current
analytical methods are not suitable for the quantification of gluten in
fermented or hydrolyzed foods (like beer). Thus, beers under our
jurisdiction that are made from gluten-containing grains cannot bear a
``gluten-free'' claim. However, as with other foods, if the gluten-
containing grain has been processed to remove gluten in accordance with
the provisions in the ``gluten-free'' definition before the
fermentation process to make beer, the beer may be eligible to make the
claim under the final rule.
We do not agree with the comments stating we should adopt TTB's
Policy. In the preamble to the proposed rule, we noted that the
labeling of beer is subject to oversight by two separate federal
agencies (80 FR 71990 at 71995). In addition, we stated that we are
working with TTB on the issues associated with ``gluten-free'' labeling
of beer to promote consistency in our approach, while taking into
consideration the differences in the statutes administered by FDA and
TTB, respectively (80 FR 71990 at 71995).
We appreciate the efforts of TTB to provide terminology for
products they regulate that do not meet the definition of ``gluten-
free,'' and as the proposed rule for gluten-free labeling of fermented
or hydrolyzed foods clearly states, and we are reiterating here, FDA-
regulated beers are not precluded from using other statements on the
label, such as a gluten statement consistent with the TTB Policy (80 FR
71990 at 71995). Such statements must be truthful and not misleading.
Beers that do not meet the definition of malt beverage are not subject
to the labeling provisions of the FAA Act, but can be subject to the
food labeling provisions of the FD&C Act and implementing regulations.
This includes the provisions concerning the use of ``gluten-free''
claims, and such statements may not expressly or implicitly suggest to
the consumer that the product is ``gluten-free'' when it does not meet
the requirements of Sec. 101.91.
(Comment 17) A few comments pointed out that fermented beverages
are different from other foods. One comment further stated that
prohibiting ``gluten-free'' claims for fermented products that are made
with gluten-containing grains, without regard for whether gluten is
present in the finished product, would conflict with the policy of the
Codex Alimentarius \1\ (Codex) on gluten claims. The comment stated
that the rule does not provide clarity that fermented alcoholic
beverages currently labeled as processed/treated to remove gluten in
accordance with the TTB Policy will be permitted to continue being so
labeled. Without clear guidance from FDA with respect to the
permissibility and standards of such labeling, the comment said that
the conditions may exist for potential disparate ``crafted to remove
gluten'' standards to arise.
---------------------------------------------------------------------------
\1\ The Codex Alimentarius is a collection of internationally
recognized standards, codes of practice, guidelines, and other
recommendations relating to foods, food production, and food safety.
http://siweb.dss.go.th/standard/Fulltext/codex/CXS_118E.pdf.
---------------------------------------------------------------------------
(Response 17) The Codex Standards for ``gluten-free'' labeling (see
Codex Standard 118-1979, section 2.1.1b) require that foods labeled as
``gluten-free'' not contain gluten-containing grains unless they have
been processed to remove gluten and the end product has less than 20
ppm gluten. Thus, contrary to the comment's assertion, our requirements
are aligned with the policy of Codex on gluten claims.
As for fermented or hydrolyzed products, the final rule applies to
FDA-regulated foods, including certain beers, and, as we stated in the
preamble to the proposed rule, we will work with TTB on the issues
associated with the ``gluten-free'' labeling of beer to promote
consistency in our approach, while taking into consideration the
differences in the statutes administered by FDA and TTB, respectively
(80 FR 71990 at 71995). The final rule does not redefine the term
``gluten-free'' or provide for the use of other statements, but rather
the rule provides how manufacturers of foods that are fermented or
hydrolyzed can comply with Sec. 101.91.
(Comment 18) Some comments stated that the TTB Policy does not
protect those with celiac disease and creates a competitive
disadvantage for beers that are truly free of gluten (as opposed to
having been processed in some manner to reduce gluten). According to
the comments, the TTB Policy allows products made from gluten-
containing grains to be labeled as being ``processed,'' ``treated,'' or
``crafted'' to remove gluten, along with a qualifying statement
indicating that the product's gluten content cannot be determined, and
that the product may contain gluten. The comments stated that certain
companies are displaying meaningless gluten test results to their
consumers. In addition, the comments expressed concern that, if TTB
adopted the same approach as our rule, manufacturers will sell low
gluten beers as ``gluten-free,'' and consumers will not be able to
differentiate between ``gluten-free'' and ``low-gluten'' products.
(Response 18) Although TTB consults with FDA about the issuance of
regulations regarding the labeling of ingredients and substances
contained in alcohol beverages, as we noted in the preamble to the 2013
gluten-free food labeling final rule (78 FR 47154 at 47165), TTB, and
not FDA, is responsible for the issuance and enforcement of regulations
with respect to the labeling of beers that are malt beverages under the
FAA Act. TTB's Policy states that, ``the term `gluten-free' may be used
on labels and in advertisements if the product would be entitled to
make a gluten-free label claim under the standards set forth in the new
FDA regulations at 21 CFR 101.91'' (Ref. 6).
We will continue to work with TTB on the issues associated with
``gluten-free'' labeling of beer to promote consistency in terminology
to avoid label statements that are either not truthful or are
misleading.
(Comment 19) One comment pointed out that proline endopeptidase
(PEP) (a yeast derived enzyme used by some manufacturers to selectively
degrade the haze-forming peptides and proteins present in beer)
provides a suitable and convenient processing aid for preparing
``gluten-free'' barley-based beverages. The comment mentioned research
done by Osman et al. 2003 (Ref. 7), which described the gradual
degradation of barley proteins during the malting stage where barley
glutens were likely to be digested to peptides. The comment also stated
that, according to Akeroyd et al. and Panda et al. (Refs. 7 and 8),
adding the enzyme during the beer fermentation phase helps to further
reduce the modest gluten concentrations present in conventionally
brewed beers. More specifically, the enzyme helps in destroying the
minimal core sequence required for T-cell recognition. The comment also
stated that if a beer shows an ELISA response below the detection
level, then the absence of peptides with
[[Page 49253]]
T-cell recognition sites is almost guaranteed. The comment said that,
after using the PEP in the brewing of beer, no known immunopathogenic
sequence is detected by mass spectrometry and the R5 Competitive ELISA
analysis fails to detect any gluten. The comment did, however,
acknowledge that a final verification on the absolute quantities of
gluten present in the end product remains necessary.
(Response 19) It has been well established that barley glutens are
not completely digested to amino acids during the malting and
fermentation stage and that the gluten fragments are present in the
final beer product (Ref. 8, Ref. 10, Ref. 11). Using mass spectrometry,
multiple research groups have detected gluten peptides in
conventionally brewed beer and beer brewed in the presence of PEP that
has tested negative for an ELISA response because the level of gluten
was below the limit of detection of ELISA test kits (Ref. 8, Ref. 9,
Ref. 10, Ref. 11). The inability to detect certain known protein
fragments in gluten that elicit a response in people with celiac
disease does not mean that all possible fragments related to celiac
disease are absent because the identities of all possible T-cell
epitopes have not been established (Ref. 12). Additionally, Fiedler et
al., were able to demonstrate that gluten peptides that contained
immunogenic sequences knowns to be associated with celiac disease were
detected in PEP-containing beer (Ref. 13). Though it is likely that PEP
breaks down gluten, that is not the goal for the use of PEP. Also, the
comments acknowledge, there is no scientifically valid analytical
method able to quantify the gluten content in terms of equivalent
amounts of intact gluten proteins.
We established the use of a 20 ppm limit as one criterion in the
definition of ``gluten-free'' because 20 ppm is currently the lowest
level at which analytical methods have been scientifically validated to
reliably and consistently detect gluten across a range of food
matrices, providing a limit for any inadvertent cross-contact with
gluten during the manufacturing process. Allowing the ``gluten-free''
label claim on food whose ingredients are derived from a gluten-
containing grain and have been processed to remove gluten, but not on
food containing such ingredients that have not been processed to remove
gluten, helps to ensure that the finished product meets the requirement
that the food contain less than 20 ppm. Further, under Sec. 101.91,
gluten-containing grains (e.g., wheat, rye, barley) are not to be used
in the production of ``gluten[hyphen]free'' products even if the
concentration of gluten in the final product was less than 20 ppm.
6. Issues Outside the Scope of This Rule
Some comments pertained to matters that were outside the scope of
this rule. However, we address several of these comments here.
Several comments stated that the term ``gluten-free'' should be
reserved only for foods that are inherently ``gluten-free.''
We addressed this issue in the 2013 gluten-free food labeling final
rule (78 FR 47154). There may be inherently gluten-free foods or
ingredients that still do not meet the definition of ``gluten-free''
due to cross-contact with gluten that leads to gluten content in the
food that is at or above 20 ppm. The rule defines ``gluten-free'' to
mean the product does not contain a gluten-containing grain or an
ingredient derived from a gluten-containing grain unless that
ingredient has been processed to remove gluten and the use of that
ingredient does not result in the presence of 20 ppm or more gluten in
the food. Also, any unavoidable presence of gluten in a product labeled
as ``gluten-free'' must be less than 20 ppm. We concluded in the
preamble to the 2013 gluten-free food labeling final rule (78 FR 47154
at 47168), that all foods bearing a ``gluten-free'' claim, regardless
if they are inherently gluten-free or not, must meet the definition of
``gluten-free.'' We chose not to limit the use of the term to only
foods that were inherently gluten-free because such an approach could
have the unintended effect of reducing the food choices available for
individuals who have celiac disease, thereby reducing the variety of
foods needed to meet their nutrient needs.
Other comments asked us to clarify our position on the use of
barley malt and barley malt extract in foods bearing a ``gluten-free''
claim.
We note that malt syrup and malt extract are interchangeable terms
for a viscous concentrate of a water extract of germinated barley, with
or without a preservative. The terms barley malt or barley malt extract
are used also. Malt syrup is usually a brown and viscous liquid
containing varying amounts of amylolytic enzymes with plant
constituents. Malt extract and malt syrup are ingredients derived from
a gluten-containing grain, barley, that have not been processed to
remove gluten. Food and ingredient manufacturers should be aware that
malt extract and other similar malt-derived ingredients are ingredients
derived from gluten-containing grains that have not been processed to
remove gluten and, therefore, cannot be used in foods that bear
``gluten-free'' labeling.
One comment said that some wheat starch contains small levels of
both intact and hydrolyzed gluten and asked us to clarify which methods
should be used to test such products because we consider wheat starch
to be ``processed to remove gluten.''
We note that wheat starch, when properly manufactured, does not
involve hydrolysis of the gluten and can be protein-free. However, as
we explain in the preamble to the 2007 proposed rule for gluten-free
food labeling, we recognize that there may be different methods of
deriving wheat starch, and that some methods may remove less gluten
than others (72 FR 2795 at 2802). Therefore, Sec.
101.91(a)(3)(i)(A)(3) prohibits a food that contains an ingredient that
is derived from a gluten-containing grain and that has been processed
to remove gluten (e.g., wheat starch) if the use of that ingredient
results in the presence of 20 ppm or more gluten in the food.
Manufacturers who label their food as ``gluten-free'' should make
certain that the food does not contain 20 ppm or more gluten,
regardless of whether or not those foods contain an ingredient that is
derived from a gluten containing grain that has been processed to
remove gluten. We would expect manufacturers of products that they wish
to label as ``gluten-free'' to use good manufacturing practices and be
aware of the practices used in production of the ingredients they use
in their products. Also, if the processing does involve hydrolysis
resulting in hydrolyzed gluten, then the product would be subject to
the requirements of this rule.
Finally, one comment asked us to clarify what government entities
regulate ``gluten-free'' claim for gluten-reduced beer on restaurant
menus and store shelves. We note that TTB is responsible for the
labeling requirements for beers, including gluten-reduced beers, that
meet the definition of malt beverage in the FAA Act (27 U.S.C.
211(a)(7)). Beers that do not meet the definition of malt beverage are
not subject to the labeling provisions of the FAA Act, but are subject
to the food labeling provisions of the FD&C Act and implementing
regulations, including the provisions concerning the use of ``gluten-
free'' or other type of gluten claims. Regarding restaurant menus that
bear a ``gluten-free'' claim, we recommend that, for beers subject to
the food labeling provisions of the FD&C Act and implementing
regulations, restaurants use the defined food labeling
[[Page 49254]]
claim ``gluten-free'' to be consistent with our ``gluten-free''
definition.
VI. Effective and Compliance Dates
This rule is effective September 14, 2020. We recognize that
manufacturers of fermented or hydrolyzed foods, or foods containing
fermented or hydrolyzed ingredients, currently bearing a ``gluten-
free'' claim may need time to review their products to ensure that
these foods comply with this final rule, or to remove ``gluten- free''
or similar claims from the label if their foods do not comply.
Compliance date: Consequently, the compliance date of this final
rule is August 13, 2021.
Although we are issuing the final rule after January 1, 2019, there
is sufficient justification for establishing the compliance date of
August 13, 2021, to enforce the provisions of this final rule, rather
than January 1, 2022, which FDA established as the next uniform
compliance date for other food labeling changes for food labeling
regulations issued between January 1, 2019, and December 31, 2020 (83
FR 65294; December 20, 2018).
We believe that 12 months from the date of publication is
sufficient time for manufacturers to review their products to ensure
that these foods comply with this final rule, or to remove ``gluten-
free'' or similar claims from the label if their foods do not comply.
This period of 12 months is consistent with what FDA has used in the
past for compliance with the requirements of voluntary food labeling
claims. We believe that waiting until FDA's next uniform compliance
date of January 1, 2022, would create an unnecessary delay in the
enforcement of this final rule, as foods bearing the voluntary labeling
``gluten-free'' that do not comply with FDA's regulatory definition of
``gluten-free'' could have an adverse public health impact on persons
with celiac disease who may be consuming those foods.
Therefore, we are establishing the compliance date to enforce the
provisions of this final rule at August 13, 2021.
VII. Economic Analysis of Impacts
We have examined the impacts of the final rule under Executive
Order 12866, Executive Order 13563, Executive Order 13771, the
Regulatory Flexibility Act (5 U.S.C. 601-612), and the Unfunded
Mandates Reform Act of 1995 (Pub. L. 104-4). Executive Orders 12866 and
13563 direct us to assess all costs and benefits of available
regulatory alternatives and, when regulation is necessary, to select
regulatory approaches that maximize net benefits (including potential
economic, environmental, public health and safety, and other
advantages; distributive impacts; and equity). Executive Order 13771
requires that the costs associated with significant new regulations
``shall, to the extent permitted by law, be offset by the elimination
of existing costs associated with at least two prior regulations.''
This final rule is not an economically significant regulatory action as
defined by Executive Order 12866.
The Regulatory Flexibility Act requires us to analyze regulatory
options that would minimize any significant impact of a rule on small
entities. Because small firms may have annualized costs that do not
exceed one percent of their annual revenue, we certify that the
proposed rule will not have a significant economic impact on a
substantial number of small entities.
The Unfunded Mandates Reform Act of 1995 (section 202(a)) requires
us to prepare a written statement, which includes an assessment of
anticipated costs and benefits, before issuing ``any rule that includes
any Federal mandate that may result in the expenditure by State, local,
and tribal governments, in the aggregate, or by the private sector, of
$100,000,000 or more (adjusted annually for inflation) in any one
year.'' The current threshold after adjustment for inflation is $156
million, using the most current (2019) Implicit Price Deflator for the
Gross Domestic Product. This final rule would not result in an
expenditure that meets or exceeds this amount in any year.
The costs of this rule are the costs to manufacturers of covered
foods of testing ingredients for gluten, evaluating potential for
cross-contact, if necessary developing and carrying out written
standard operating procedures (SOPs) for preventing gluten cross-
contact, relabeling products that cannot be brought into compliance,
and maintaining records of these activities for FDA inspection. We
estimate total annualized costs of $7 million to $11 million for the 3%
discount rate and annualized costs ranging from $7 million to $11
million at 7% discount rate. All costs are computed in 2018-dollar
values.
The benefits of this rule are health gains for people with celiac
disease using ``gluten-free'' labeled foods while maintaining a gluten-
free diet. To examine the potential scope of these benefits, we
simulate the harm done by dietary gluten intake from a gluten-free diet
before and after the rule. Due to uncertainty in this simulation
analysis, we describe benefits qualitatively. For the rule to break-
even with costs, the annualized benefits would need to be at least $8.8
million at a 3% discount rate and a $9.1 million at a 7% discount rate.
Based on our simulation analysis, the rule would break-even with
primary cost estimates discounted at 7% if at least 0.07% of estimated
individuals with celiac disease following a gluten-free diet benefit
from the rule each year.

VIII. Analysis of Environmental Impact
We have determined under 21 CFR 25.30(k) that this action is of a
type that does not individually or cumulatively have a significant
effect on the human environment. Therefore, neither an environmental
assessment nor an environmental impact statement is required.
IX. Paperwork Reduction Act of 1995
This final rule contains information collection provisions that are
subject to review by OMB under the Paperwork Reduction Act of 1995 (44
U.S.C. 3501-3521). A description of these provisions is given in this
section of the document with an estimate of the annual recordkeeping
burden. Included in the burden estimate is the time for reviewing
instructions, searching existing data sources, gathering and
maintaining the data needed, and completing and reviewing each
collection of information.
[[Page 49256]]
Recordkeeping Requirements for Gluten-Free Labeling of Fermented or
Hydrolyzed Foods
1. Description of Respondents
Manufacturers of foods that are fermented, hydrolyzed, or contain
fermented or hydrolyzed ingredients and bear the claim ``gluten-free,''
``no gluten,'' ``free of gluten,'' or ``without gluten.''
2. Description
In this final rule, we require manufacturers of certain food
products covered by the rule to make and keep records providing
adequate assurance that: (1) The food is ``gluten-free'' before
fermentation or hydrolysis; (2) the manufacturer has evaluated the
potential for cross-contact with gluten during the manufacturing
process; and (3) if necessary, measures are in place to prevent the
introduction of gluten into the food during the manufacturing process.
Manufacturers using an ingredient that is a fermented or hydrolyzed
food are only required to make and keep these records for the fermented
or hydrolyzed ingredient. We estimate that the manufacturers can
satisfy the recordkeeping requirements of this rule by maintaining
records of their tests or other appropriate verification procedures,
their evaluation of the potential for gluten cross-contact, and their
standard operating procedures (SOPs) for preventing gluten cross-
contact. It is also possible that manufacturers can instead comply with
this rule by obtaining and maintaining records of Certificates of
Analysis (CoA), test results, or other appropriate verification
procedures from their suppliers.
Written SOPs and records of testing and other activities are
essential for FDA to be able to determine compliance with Sec. 101.91
for these products. Records need to be reasonably accessible at each
manufacturing facility and could be examined periodically by FDA
inspectors during an inspection to determine whether the food has been
manufactured and labeled in compliance with Sec. 101.91. Records that
can be immediately retrieved from another location by electronic means
are considered reasonably accessible.
We estimate the burden of this collection of information as
follows: We base our estimates of the average burden per recordkeeping
on our experience with good manufacturing practices used to control the
identity and composition of food and to limit contaminants and prevent
adulteration. The hour estimates for the recordkeeping burdens
presented here are averages. We anticipate that the records kept would
vary based on the type of ingredients used. Some manufacturers, such as
those producing fermented dairy products, would likely maintain fewer
records overall. Other manufacturers, such as those producing foods
with fermented or hydrolyzed grains, legumes, or seeds, would likely
maintain more extensive records.
Our estimates of the numbers of manufacturers/recordkeepers
reported in column 2 of tables 3 and 4 are based on the number of food
products that are covered by the rule. Our search of FoodEssentials
database was completed in November of 2017 (Ref. 15) for foods that are
hydrolyzed, fermented, or contain fermented or hydrolyzed ingredients
and bear the labeling claim ``gluten-free,'' ``no gluten,'' ``free of
gluten,'' or ``without gluten,'' and found about 2,500 products that
are affected by the rule. Based on our understanding of the market and
experience with the percentage of the food market covered by this
database, we estimate that this database has at least half of all
products that are covered by the rule, so that there are likely, at
most, 5,000 products affected by the rule.
We do not have any data about how many products are produced in
each facility, so we assume that each product and its production line
would be tested separately and would require a separate evaluation and
SOP. Thus, we estimate the number of food production facilities and,
accordingly, the number of manufacturers/recordkeepers to be 5,000. If
multiple products are produced in the same facility and can share
testing, evaluation, and SOPs, then the recordkeeping burden would be
less than these estimates.
We do not know how many products are already being manufactured
using gluten-free ingredients and/or with a process designed to prevent
gluten introduction. A survey of food industry practices (Ref. 16)
shows that about 45 percent of all food production facilities have a
written allergen control plan, and about 39 percent require
certificates of analysis for ingredients. Given that manufacturers of
foods labeled ``gluten-free'' are marketing to customers who care more
about gluten cross-contact, we estimate that about 75 percent of the
5,000 foods with a ``gluten-free'' labeling claim already have a
written plan for preventing the introduction of gluten into the food
product that includes the testing of ingredients and procedures for
evaluating and preventing gluten cross-contact. Therefore, we estimate
that 1,250 facilities would incur new SOP development and ingredient
testing burdens, and all 5,000 facilities would incur certain new
recordkeeping burdens.
3. Recordkeeping Burden Related to Standard Operating Procedures
We estimate that 1,250 facilities do not have a written SOP for
preventing the introduction of gluten into the food product. For these
facilities, developing an SOP is a first year burden of the rule. We
estimate that it takes a facility an average of seven hours to develop
an SOP for gluten control. Thus, we estimate that in the first year of
compliance with this final rule, 1,250 facilities would develop an SOP
for a burden of 8,750 hours (1,250 facilities x 7 hours per facility =
8,750 hours), as reported in Table 3, row 1.
Updating the facility's SOP for gluten control would be a recurring
burden of the rule for the 1,250 facilities that do not currently have
an SOP. We estimate that it takes a facility about 0.7 hours (42
minutes) annually to update its SOP for gluten control, for a burden of
875 hours (1,250 facilities x 0.7 hours per facility = 875 hours), as
reported in table 4, row 1.
We estimate that maintaining records of their updated SOPs would be
a recurring burden of this rule for all 5,000 facilities. We estimate
that it takes each facility one hour annually to maintain records of
its updated SOPs for gluten control, for a burden of 5,000 hours (5,000
facilities x 1 hour per facility = 5,000 hours), as reported in table
4, row 2.
4. Recordkeeping Burden Related to Testing
To demonstrate that a food is ``gluten-free'' before fermentation
or hydrolysis, we expect that most manufacturers would test their
incoming ingredients or obtain Certificates of Analysis from their
ingredient suppliers. A manufacturer may test ingredients for gluten by
sending ingredient samples to a testing company or by using test kits
to test ingredient samples on site at their facility. Test kits would
first undergo method validation for the testing situation in which they
are to be used (Ref. 17). We assume that a manufacturer that begins a
program of testing the gluten content of an ingredient will start by
sending several samples to a lab and obtaining method extension for a
test kit for the ingredient. Obtaining a validation for a test kit is a
first-year burden only for existing products.
After the first year of testing, we assume the manufacturers would
then use test kits to test the ingredient on a
[[Page 49257]]
regular basis, and may also send one or two samples a year to an
outside lab for testing. These are recurring testing burdens. Based on
the variety of products under FDA's jurisdiction that are fermented or
hydrolyzed, we estimate that an average of two ingredients per product
would be tested in this manner. Most foods affected by this rule are
those that contain a single fermented or hydrolyzed ingredient. As
explained earlier, adequate assurance that these fermented or
hydrolyzed ingredient(s) were gluten-free before that supplier
performed hydrolysis or fermentation can include test results, CoAs, or
other appropriate verification documentation for each of the
ingredients. Other products contain multiple ingredients that would be
tested before fermentation or hydrolysis.
As described above, we estimate that most manufacturers (75
percent) already have a gluten control SOP that includes testing, so
they will not undertake any additional testing as a result of this
rule. In the first year of compliance, we estimate that the 1,250
manufacturers not currently testing their ingredients and production
facilities for gluten would incur additional testing burdens as a
result of this rule. For these manufacturers, obtaining a method
extension for a test kit would be a first year burden of this rule. We
estimate that 1,250 manufacturers would conduct seven tests for method
extension, for each of two ingredients, for a total of 14 samples. We
estimate that it would take a manufacturer 5 minutes to collect each
sample, for a total of 1,458 hours (1,250 manufacturers x 14 samples
per manufacturer x (5 minutes / 60 minutes per hour) = 1,458 hours) as
reported in Table 3, row 2. We estimate that this rule results in
manufacturers conducting 17,500 laboratory tests in the first year
(1,250 manufacturers x 14 samples to be tested per manufacturer =
17,500 samples to be tested). These tests have an average cost of
$84.33, which means that the estimated capital costs related to this
first year paperwork burden is about $1.5 million (17,500 tests x
$84.33 per test = $1,475,833) as reported in table 3, row 2.
We estimate that, as a first year burden of this rule, all 5,000
manufacturers would begin retaining records of the method extension
tests. We estimate that it takes a manufacturer 30 minutes per record,
for a total of 35,000 hours (5,000 manufacturers x 14 sample records
per manufacturer x 0.5 hours per sample record = 35,000 hours), as
reported in table 3, row 3.
We estimate that testing ingredients on a regular basis would be a
recurring burden of the rule, for the 1,250 manufacturers not currently
testing their ingredients and production facilities for gluten. We
estimate that 1,250 manufacturers will use 21 test kits annually on
average per ingredient, for a total of 42 kits, and that each test will
require 5 minutes to collect a sample and 30 minutes to process and
file the test results. We estimate that the burden of collecting
samples for these tests is 4,375 hours (1,250 manufacturers x 42 test
kits per manufacturer x (5 minutes per test kit / 60 minutes per hour)
= 4,375 hours), as reported in table 4, row 3. We estimate that this
rule, results in manufacturers using 52,500 test kits each year (1,250
manufacturers x 42 test kits per manufacturer = 52,500 test kits).
These test kits have an average cost of $11, which means that the
estimated capital costs related to this recurring paperwork burden is
about $0.6 million (52,500 test kits x $11 per kit = $577,500), as
reported in Table 4, row 3. We estimate the burden to process and
maintain records of the test results would be 105,000 hours (5,000
manufacturers x 42 test kits per manufacturer x 0.5 hours per test kit
= 105,000 hours), as reported in table 4, row 4.
We estimate that a recurring burden of this rule, for all 5,000
manufacturers, is to send one or two samples a year to an outside lab
for testing. We estimate that 5,000 manufacturers will conduct one
outside test annually on average per ingredient, for a total of 2
tests, and that each test will require 5 minutes to collect a sample
and 30 minutes to process and file the test results. We estimate that
the burden of collecting samples for these tests is 208 hours (1,250
manufacturers x 2 tests per manufacturer x (5 minutes / 60 minutes per
hour) = 208 hours), as reported in table 4, row 5. We estimate that
this rule results in manufacturers conducting 2,500 laboratory tests in
the first year (1,250 manufacturers x 2 tests per manufacturer = 2,500
tests). These tests have an average cost of $84.33, which means that
the estimated capital costs related to this recurring paperwork burden
is about $0.2 million (2,500 tests x $84.33 per test = $210,833), as
reported in table 4, row 5. We estimate the burden to process and
maintain records of the test results is 5,000 hours (5,000
manufacturers x 2 tests per manufacturer x 0.5 hours per test = 5,000
hours), as reported in table 4, row 6.

The information collection provisions in this final rule have been
submitted to OMB for review as required by section 3507(d) of the
Paperwork Reduction Act of 1995.
Before the effective date of this final rule, FDA will publish a
notice in the Federal Register announcing OMB's decision to approve,
modify, or disapprove the information collection provisions in this
final rule. An Agency may not conduct or sponsor, and a person is not
required to respond to, a collection of information unless it displays
a currently valid OMB control number.
X. Federalism
We have analyzed this final rule in accordance with the principles
set forth in Executive Order 13132. Section 4(a) of Executive Order
13132 requires Agencies to ``construe . . . a Federal statute to
preempt State law only where the statute contains an express preemption
provision or there is some other clear evidence that the Congress
intended preemption of State law, or where the exercise of State
authority conflicts with the exercise of Federal authority under the
Federal statute.'' Here, as in the 2013 gluten-free food labeling final
rule published in the August 5, 2013, issue of the Federal Register (78
FR 47154 at 47175), we have determined that certain narrow exercises of
State authority would conflict with the exercise of Federal authority
under the FD&C Act.
In section 206 of FALCPA, Congress directed us to issue a proposed
rule to define and permit use of the term ``gluten-free'' on the
labeling of foods, in consultation with appropriate experts and
stakeholders, to be followed by a proposed rule for the use of such
term in labeling. In the preamble to the 2007 gluten-free food labeling
proposed rule (72 FR 2795 at 2813 through 2814), we indicated that we
had consulted with numerous experts and stakeholders in proposed rule's
development and determined that certain narrow exercises of State
authority would conflict with the exercise of Federal authority under
the FD&C Act. Different and inconsistent amounts of gluten in foods
with ``gluten-free'' labeling result in the inability of those
individuals with celiac disease who adhere to a gluten-free diet to
avoid exposure to gluten at levels that may result in adverse health
effects. ``Gluten-free'' labeling, for purposes of this discussion,
also includes the use of the terms ``no gluten,'' ``free of gluten,''
and without gluten,'' as indicated in Sec. 101.91(b)(2). There is a
need for national uniformity in the meaning of the term ``gluten-
free,'' which includes the manner in which the definition is enforced,
so that most individuals with celiac disease can make informed
purchasing decisions that will enable them to adhere to a diet they can
tolerate without causing adverse health effects and can select from a
variety of available gluten-free foods.
This final rule establishes additional requirements for
manufacturers of fermented and hydrolyzed foods or foods that contain
fermented and hydrolyzed ingredients wishing to use the terms ``gluten-
free,'' ``no gluten,'' ``free of gluten,'' or ``without gluten'' on
their products, thus these requirements are a component of how we
permit the use of the ``gluten-free'' labeling claim. If States were
able to establish different requirements regarding what manufacturers
of fermented or hydrolyzed foods would need to demonstrate in order to
use the term ``gluten-free,'' then individuals with celiac disease
would not be able to rely on a consistent meaning for that term and
thereby use the term to identify appropriate dietary selections. As a
result, individuals with celiac disease may unnecessarily limit their
food choices, or conversely, select foods with levels of gluten that
are not tolerated and that may cause adverse health effects. Food
manufacturers, if confronted by a State or various State requirements
that adopted different requirements for fermented or hydrolyzed foods
than this rule, might decide to remove the ``gluten-free'' label, and
such a result would make it more difficult for individuals with celiac
disease to identify foods that they can tolerate and achieve a dietary
intake from a variety of foods to meet an individual's nutrient needs.
Moreover, consistent requirements regarding the way compliance with the
final rule is determined, including the records that would need to be
maintained in order for a fermented or hydrolyzed food manufacturer to
use the ``gluten-free'' claim and the use of a scientifically valid
method to detect the absence of protein to determine compliance for
distilled products, enables us to more efficiently enforce the use of
the ``gluten-free'' claim across all fermented and hydrolyzed foods to
ensure labels bearing a ``gluten-free'' claim are truthful and not
misleading.
Therefore, the final rule's objective is standardizing use of the
term ``gluten-free'' in the labeling of fermented and hydrolyzed foods
so that foods with this claim in labeling, and foods with a
[[Page 49259]]
claim of ``no,'' ``free of,'' and ``without'' gluten, which connote a
similar meaning to that of ``gluten-free,'' are used in a consistent
way and will prevent consumer confusion and help individuals with
celiac disease make purchasing decisions.
Section 4(c) of Executive Order 13132 instructs us to restrict any
Federal preemption of State law to the ``minimum level necessary to
achieve the objectives of the statute pursuant to which the regulations
are promulgated.'' The final rule meets the preceding requirement
because it would preempt State law narrowly, only to the extent
required to achieve uniform national labeling with respect to the
requirements related to the use of the term ``gluten-free,'' as well as
the terms ``no gluten,'' ``free of gluten,'' or ``without gluten,'' on
fermented and hydrolyzed foods. We intend to preempt State or local
requirements only to the extent that the State or local requirements
are different from the labeling requirements in this section related to
the use of the terms ``gluten-free,'' ``no gluten,'' ``free of
gluten,'' or ``without gluten'' for fermented and hydrolyzed foods. In
addition, we cannot foresee every potential State requirement and
preemption that may arise if a State requirement is found to obstruct
the federal purpose articulated in this rule. This rule, like the rule
codified at Sec. 101.91, is not intended to preempt other State or
local labeling requirements with respect to other statements or
warnings about gluten. For example, a State is not preempted from
requiring a labeling statement about the health effects of gluten
consumption from fermented or hydrolyzed foods on persons with celiac
disease or information about how the food was processed.
In 2009, the President issued a memorandum entitled ``Preemption''
(74 FR 24693, May 22, 2009). The memorandum, among other things,
instructs Agencies to ``not include in regulatory preambles statements
that the department or agency intends to preempt State law through the
regulation except where preemption provisions are also included in the
codified regulation'' and ``not include preemption provisions in
codified regulations except where such provisions would be justified
under legal principles governing preemption, including the principles
outlined in Executive Order 13132.'' Because of the May 22, 2009,
memorandum we explain in detail the principles underlying our
conclusion that this final rule may result in preemption of State and
local laws under a narrow set of circumstances and describe how the
final rule's codified provision regarding preemption, which is now
Sec. 101.91(d), would apply to fermented or hydrolyzed foods.
Under the Supremacy Clause of the Constitution (U.S. Constitution;
Art. VI, clause 2), State laws that interfere with or are contrary to
Federal law are invalid. (See Gibbons v. Ogden, 22 U.S. (9 Wheat.) 1,
211 (1824)). Federal preemption can be express (stated by Congress in
the statute) or implied. Implied preemption can occur in several ways.
For example, Federal preemption may be found where Federal law
conflicts with State law. Such conflict may be demonstrated either when
``compliance with both federal and state [law] is a physical
impossibility'' (Florida Lime and Avocado Growers, Inc. v. Paul, 373
U.S. 132, 142-143 (1963)), or when State law ``stands as an obstacle to
the accomplishment and execution of the full purposes and objectives of
Congress'' (Crosby v. Nat'l Foreign Trade Council, 530 U.S. 363, 372-74
(2000) (citing Hines v. Davidowitz, 312 U.S. 52, 67 (1941))). State law
is also preempted if it interferes with the methods by which a Federal
law is designed to reach its goals. (See Int'l Paper Co. v. Ouellette,
479 U.S. 481, 494 (1987); Michigan Canners & Freezers Ass'n v.
Agricultural Marketing & Bargaining Bd., 467 U.S. 461, 477-478 (1984)).
Additionally, `` `a federal agency acting within the scope of its
congressionally delegated authority may preempt state regulation' and
hence render unenforceable state or local laws that are otherwise not
inconsistent with federal law'' (City of New York v. FCC, 486 U.S. 57,
63-64 (1988) (quoting Louisiana Public Service Comm'n v. FCC, 476 U.S.
355, 369 (1986)). ``Federal regulations have no less preemptive effect
than federal statutes'' (Fidelity Federal Savings and Loan Ass'n v. de
la Cuesta, 458 U.S. 141, 153 (1982)).
When an Agency's intent to preempt is clearly and unambiguously
stated, a court's inquiry will be whether the preemptive action is
within the scope of that Agency's delegated authority (Capital Cities
Cable, Inc. v. Crisp, 467 U.S. 691, 700 (1984); Fidelity Federal
Savings, 458 U.S. at 154). If the Agency's choice to preempt
``represents a reasonable accommodation of conflicting policies that
were committed to the agency's care by the statute [the regulation will
stand] unless it appears from the statute or its legislative history
that the accommodation is not one that Congress would have sanctioned''
(United States v. Shimer, 367 U.S. 374, 383 (1961)). In Hillsborough
County, the Supreme Court stated that FDA possessed the authority to
issue regulations preempting local laws that compromise the supply of
plasma and could do so (Hillsborough County, Fla. v. Automated Medical
Laboratories, Inc., 471 U.S. 707, 721 (1985)). We believe we have
similar authority to preempt State and local laws and regulations to
the limited extent that they permit use of ``gluten-free,'' ``no
gluten,'' ``free of gluten,'' or ``without gluten'' for fermented or
hydrolyzed foods differently from our rule because different State or
local labeling requirements would be contrary to the Congressional
directive for us to define and permit use of the term ``gluten-free.''
State or local laws or regulations that permit use of ``gluten-
free,'' ``no gluten,'' ``free of gluten,'' or ``without gluten''
differently from our rule could frustrate the ability of most consumers
to identify gluten-free foods and avoid adverse health effects and
deter manufacturers from applying a ``gluten-free'' label to their
foods. With this final rule, consumers throughout the United States can
understand what is required to use the term ``gluten-free'' on the
labeling of a fermented or hydrolyzed packaged food. This final rule
will also allow us to enforce more efficiently the definition on
product labels of fermented or hydrolyzed foods, and manufacturers will
be able to comply with a single set of requirements, which may lead to
greater use of this voluntary labeling.
Therefore, we intend to preempt State or local requirements only to
the extent that they are different from these final requirements
related to the use of the terms ``gluten-free,'' ``no gluten,'' ``free
of gluten,'' or ``without gluten'' on the labeling of fermented or
hydrolyzed foods, including the requirement to make and keep certain
records and the use of a scientifically valid method to detect the
absence of protein for distilled foods. There is no change to Sec.
101.91(d) regarding preemption, but the new requirements in Sec.
101.91(c) are part of the requirements covered by Sec. 101.91(d).

List of Subjects in 21 CFR Part 101
Food labeling, Nutrition, Reporting and recordkeeping requirements.
Therefore, under the Federal Food, Drug, and Cosmetic Act and under
authority delegated to the Commissioner of Food and Drugs, 21 CFR part
101 is amended as follows:
PART 101--FOOD LABELING
0
1. The authority citation for 21 CFR part 101 continues to read as
follows:
Authority: 15 U.S.C. 1453, 1454, 1455; 21 U.S.C. 321, 331, 342,
343, 348, 371; 42 U.S.C. 243, 264, 271.

2. In Sec. 101.91, revise paragraphs (b)(1), (b)(2), and (c) to read
as follows:
Sec. 101.91 Gluten-free labeling of food.
* * * * *
(b) Requirements. (1) A food that bears the claim ``gluten-free''
in its labeling and fails to meet the requirements of paragraph (a)(3)
of this section and, if applicable, paragraphs (c)(2) through (4) of
this section will be deemed misbranded.
(2) A food that bears the claim ``no gluten,'' ``free of gluten,''
or ``without gluten'' in its labeling and fails to meet the
requirements of paragraph (a)(3) of this section and, if applicable,
paragraphs (c)(2) through (4) of this section will be deemed
misbranded.
* * * * *
(c) Compliance. (1) When compliance with paragraph (b) of this
section is based on an analysis of the food, FDA will use a
scientifically valid method that can reliably detect and quantify the
presence of 20 ppm gluten in a variety of food matrices, including both
raw and cooked or baked products.
(2) When a scientifically valid method pursuant to paragraph (c)(1)
of this section is not available because the food is fermented or
hydrolyzed, the manufacturer of such foods bearing the claim must make
and keep records regarding the fermented or hydrolyzed food
demonstrating adequate assurance that:
(i) The food is ``gluten-free'' in compliance with paragraph (a)(3)
of this section before fermentation or hydrolysis;
(ii) The manufacturer has adequately evaluated their processing for
any potential for gluten cross-contact; and
(iii) Where a potential for gluten cross-contact has been
identified, the manufacturer has implemented measures to prevent the
introduction of gluten into the food during the manufacturing process.
(3) When a scientifically valid method pursuant to paragraph (c)(1)
of this section is not available because the food contains one or more
ingredients that are fermented or hydrolyzed, the manufacturer of such
foods bearing the claim must make and keep records demonstrating
adequate assurance that the fermented or hydrolyzed ingredients are
``gluten-free'' as described in paragraph (c)(2) of this section.
(4) Records necessary to verify compliance with paragraphs (c)(2)
and (3) of this section must be retained for at least 2 years after
introduction or delivery for introduction of the food
[[Page 49261]]
into interstate commerce and may be kept as original records, as true
copies, or as electronic records. Manufacturers must provide those
records to us for examination and copying during an inspection upon
request.
(5) When a scientifically valid method pursuant to paragraph (c)(1)
of this section is not available because the food is distilled, FDA
will evaluate compliance with paragraph (b) of this section by
verifying the absence of protein in the distilled component using
scientifically valid analytical methods that can reliably detect the
presence or absence of protein or protein fragments in the food.
