SUPPLEMENTARY INFORMATION: FDA has had inquiries concerning whether the
DSHEA applies to products intended for use in animals. After examining
the statutory language, intent, and legislative history, the agency has
determined that the DSHEA does not apply to animal products.
On October 25, 1994, the DSHEA (Pub. L. 103-417) was signed into
law. The DSHEA amends the Federal Food, Drug, and Cosmetic Act (the
act) to create a new regulatory scheme for ``dietary supplements.'' The
DSHEA, among other things, amended the act by adding section 201(ff)
(21 U.S.C. 321(ff)), which defines a ``dietary supplement,'' in part,
as a product, other than tobacco, intended to supplement the diet that
contains at least one or more of the following ingredients: A vitamin;
a mineral; an herb or other botanical; an amino acid; a dietary
substance for use to supplement the diet by increasing the total
dietary intake; or a concentrate, metabolite, constituent, extract, or
combination of any of the previously
[[Page 17707]]
mentioned ingredients (section 201(ff)(1) of the act). The DSHEA's main
effect on the act was the removal of certain dietary supplement
ingredients from regulation under 21 U.S.C. 321(s) and 348, two
provisions of the act regulating the safety of food ingredients. In
addition, the DSHEA permits certain limited claims to be made about
dietary supplements without resulting in the supplement becoming a drug
under 21 U.S.C. 321(g).
The definition of ``dietary supplement'' in the DSHEA does not
explicitly state whether it includes or excludes products intended for
use in animals other than man. The legislative record, which is
extremely brief, is likewise silent about this issue. FDA has carefully
examined the new law to determine if it should be applied to animal
products, and believes that it should not. When the DSHEA is read as a
whole, FDA believes it is evident that Congress was concerned only with
human products and did not consider animal products. For this reason,
the agency concludes that Congress did not intend the law to apply to
animal products. Equally important, there are some critical differences
between products intended for human use and products intended for
animal use that strongly favor maintaining the status quo for animal
products. Accordingly, FDA does not intend to apply the DSHEA to animal
products.
There is much evidence in the DSHEA that Congress did not intend to
apply the amendments to animal products. First, the extensive
congressional findings in section 2 of the DSHEA focus strictly on the
use of dietary supplements by humans. These findings begin by stating
that ``improving the health status of United States citizens ranks at
the top of the national priorities * * *,'' id., section 2(l) of the
DSHEA (emphasis added); see also id., section 2(3)(A) and (2)(4) of the
DSHEA (discussing the effect of supplements on human health conditions,
such as ``cancer, heart disease, and osteoporosis'' and ``medical
procedures, such as coronary bypass surgery or angioplasty.'') This
strict focus on humans in the congressional findings reflects Congress'
intent that the law apply only to humans. See United States v. Solid
Gold Holistic Animal Equine Nutrition Center et al., No. CV 88-0473-GT,
slip op. at 7-8 (S.D. Cal. March 2, 1995) (Ref. 1).
Next, although the definition of ``dietary supplement'' contains no
explicit reference to products intended for use by animals, part of the
definition does contain an explicit reference to products intended for
use by humans (section 3 of the DSHEA (creating 21 U.S.C.
321(ff)(1)(E))). This is further evidence that Congress intended the
law to apply to supplements used by humans, not supplements for other
animals.
Furthermore, many of the changes made by the DSHEA apply only to
supplements intended for human use because the sections of the act that
were amended by the DSHEA apply only to human products--yet another
strong signal that Congress was only concerned with human supplements.
For example, when the DSHEA sets out the standards for determining
whether a product that has been approved or investigated as a drug can
also be sold as a dietary supplement, it cites only to the human drug
provisions of the act, but not to any of the animal drug provisions.
See 21 U.S.C. 321(ff)(3). Likewise, the changes to food labeling made
by the DSHEA apply only to human food because the sections in the act
that are amended are in 21 U.S.C. 343(r), which applies only to ``food
for human consumption.''
Moreover, FDA believes the public health will be better protected
if ingredients in animal dietary supplements are not subject to the
special treatment provided for ingredients of human supplements by the
DSHEA. Under the act's food additive provisions, 21 U.S.C. 321(s) and
348, before FDA can approve a product for use in a food producing
animal, FDA must determine that the product will not leave harmful
residues in food (21 U.S.C. 348(b)(2) and (c)(5), and 21 CFR part 570).
If the compound or any of its metabolites induces cancer, the act
imposes additional requirements on the approval of the compound (21
U.S.C. 348(c)(3)(A) and 21 CFR part 500, subpart E). However, nowhere
in its revision of the regulation of ingredients in dietary supplements
does the DSHEA address how the effect of supplements on food producing
animals and human food safety is to be assessed. It seems unlikely that
Congress would so alter the regulation of animal foods with no
consideration--indeed, no mention--of the impact of the alteration on
the safety of the nation's food supply.\1\
---------------------------------------------------------------------------
The findings make clear that one underpinning of the new
legislation was Congressional concern that consumers should have the
freedom to make their own choices about whether to take dietary
supplements. However, that critical element of consumer choice is
lacking when the supplement (or its metabolite) ends up in the diet
as an unidentified residue in meat, milk, or eggs.
---------------------------------------------------------------------------
Not only are there human food safety concerns, but when compared
with human use of supplements, there is less information on the safe
use of dietary supplements in animals. Many substances that fall under
the definition of dietary supplements for human consumption, such as
herbs and other botanicals, have a history of use in humans that can be
used to establish reasonably safe levels. However, the same is not true
for use of many of these same ingredients in animals. As far as FDA is
aware, very few substances that meet the criteria of 21 U.S.C.
321(ff)(1) and (ff)(2) have any established history of safe use in any
animal. Moreover, each animal species requires different nutrients,
absorbs and metabolizes nutrients differently, and can exhibit
different toxic reactions to food and its components. The lack of
information on the safe use of these kinds of substances in animals,
and the fact that the animal population is not as homogenous as the
human population are two more reasons why FDA has determined that the
DSHEA should not apply to animal products.\2\
---------------------------------------------------------------------------
\2\The law devotes no resources to the human and animal health
issues raised by the use of supplements in animals. The DSHEA does
mandate the establishment of an office within the National
Institutes of Health to oversee scientific study of dietary
supplements, as well as a seven-member commission to provide
recommendations for the regulation of label claims for supplements.
However, nothing in the law directs either new group to address the
use of dietary supplements in animals. Thus, there will not be any
independent resource from which the Center for Veterinary Medicine
(CVM) can obtain unbiased information on benefits to animal health
and production, safety to animals and humans consuming edible
byproducts from treated animals, or the validity of claims for
animal supplements. Lacking such a resource, FDA believes it is
prudent for the burden to remain, as it is now, on the manufacturer
to generate safety and effectiveness data and provide it to FDA for
review in feed additive petitions and new animal drug applications.
---------------------------------------------------------------------------
Finally, many drugs intended to increase the production of meat,
milk, egg, or fiber (so-called production drugs) or otherwise affect
animal performance could arguably be covered as dietary supplements
under the DSHEA. Currently, products bearing such production claims are
animal drugs under the act, and as such, can only be marketed after
approval by FDA after the manufacturer conducts extensive scientific
studies to show that the drug is both safe (in animals and humans) and
effective (21 U.S.C. 360b). To allow new production drugs to be
marketed under the provisions of the DSHEA not only raises exactly the
same food safety concerns previously discussed about food additives,
but would also be unfair to existing approved products, and would serve
as a disincentive to develop and use legitimate drugs in the future.
In sum, although the DSHEA does not speak directly to the question,
we think that the DSHEA was not intended to apply to animal products.
Moreover, we
[[Page 17708]]
believe that there are significant, complex scientific and regulatory
issues relating to human and animal safety that would need to be
resolved by Congress before a similar scheme for animal supplements
could be put into place. Accordingly, FDA has concluded that animal
dietary supplements are not covered by the DSHEA.
