Duddingtonia flagrans strain IAH 1297; Exemption from the 
Requirement of a Tolerance

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This regulation establishes an exemption from the requirement 
of a tolerance for residues of Duddingtonia flagrans strain IAH 1297 in 
or on all food commodities when used in accordance with label 
directions and good agricultural practices. International Animal Health 
Products Pty. Ltd. submitted a petition to EPA under the Federal Food, 
Drug, and Cosmetic Act (FFDCA), requesting an exemption from the 
requirement of a tolerance. This regulation eliminates the need to 
establish a maximum permissible level for residues of Duddingtonia 
flagrans strain IAH 1297 under FFDCA.

DATES: This regulation is effective May 7, 2018. Objections and 
requests for hearings must be received on or before July 6, 2018, and 
must be filed in accordance with the instructions provided in 40 CFR 
part 178 (see also Unit I.C. of the SUPPLEMENTARY INFORMATION).

II. Background and Statutory Findings

    In the Federal Register of October 23, 2017 (82 FR 49022) (FRL-
9967-37), EPA issued a document pursuant to FFDCA section 408(d)(3), 21 
U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance 
petition (PP 6F8531) by International Animal Health Products Pty. Ltd., 
18 Healey Circuit, Huntingwood, New South Wales 2148, Australia (in 
care of SciReg. Inc., 12733 Director's Loop, Woodbridge, VA 22192). The 
petition requested that 40 CFR part 180 be amended by establishing an 
exemption from the requirement of a tolerance for residues of 
Duddingtonia flagrans strain IAH 1297 in or on all raw and processed 
agricultural commodities. That document referenced a summary of the 
petition prepared by the petitioner International Animal Health 
Products Pty. Ltd., which is available in the docket via http://www.regulations.gov.

[[Page 19969]]

There were no comments received in response to the notice of filing.
    EPA changed the commodity to be reflected in the tolerance 
expression from ``in or on all raw and processed agricultural 
commodities'' to ``in or on all food commodities.'' The reason for this 
change is explained in Unit VII.B.
    Section 408(c)(2)(A)(i) of FFDCA allows EPA to establish an 
exemption from the requirement for a tolerance (the legal limit for a 
pesticide chemical residue in or on a food) only if EPA determines that 
the exemption is ``safe.'' Section 408(c)(2)(A)(ii) of FFDCA defines 
``safe'' to mean that ``there is a reasonable certainty that no harm 
will result from aggregate exposure to the pesticide chemical residue, 
including all anticipated dietary exposures and all other exposures for 
which there is reliable information.'' This includes exposure through 
drinking water and in residential settings but does not include 
occupational exposure. Pursuant to FFDCA section 408(c)(2)(B), in 
establishing or maintaining in effect an exemption from the requirement 
of a tolerance, EPA must take into account the factors set forth in 
FFDCA section 408(b)(2)(C), which require EPA to give special 
consideration to exposure of infants and children to the pesticide 
chemical residue in establishing a tolerance or tolerance exemption and 
to ``ensure that there is a reasonable certainty that no harm will 
result to infants and children from aggregate exposure to the pesticide 
chemical residue . . . .'' Additionally, FFDCA section 408(b)(2)(D) 
requires that EPA consider ``available information concerning the 
cumulative effects of [a particular pesticide's] . . . residues and 
other substances that have a common mechanism of toxicity.''
    EPA performs a number of analyses to determine the risks from 
aggregate exposure to pesticide residues. First, for microbial 
pesticides, EPA determines the pathogenicity and toxicity of the 
pesticide. Second, EPA examines exposure to the pesticide through food, 
drinking water, and other exposures that occur as a result of pesticide 
use in residential settings, as well as other non-occupational exposure 
to the substance.

III. Toxicological Profile

    Consistent with FFDCA section 408(b)(2)(D), EPA reviewed the 
available scientific data and other relevant information on 
Duddingtonia flagrans strain IAH 1297 and considered their validity, 
completeness, and reliability, as well as the relationship of this 
information to human risk. EPA also considered available information 
concerning the variability of the sensitivities of major identifiable 
subgroups of consumers, including infants and children.

A. Overview of Duddingtonia flagrans Strain IAH 1297 (Refs. 1 and 2)

    Duddingtonia flagrans is a fungus commonly found worldwide in 
soils, various plant materials, and animal feces that, in the presence 
of nematodes, forms looped adhesive network traps in animal feces in 
pasture when the diet of grazing animals is supplemented with the 
fungus' chlamydospores or the chlamydospores are acquired naturally 
from soil or plant material while the animals graze. Duddingtonia 
flagrans strain IAH 1297 chlamydospores can survive passage through the 
rumen and gastrointestinal tract after ingestion by grazing animals and 
then germinate on pasture (i.e., the chlamydospores do not germinate in 
animals and cannot grow at normal body temperature or under anaerobic 
conditions). Nematode eggs excreted by pastured or wild animals hatch 
in the presence of Duddingtonia flagrans strain IAH 1297. Thereafter, 
Duddingtonia flagrans strain IAH 1297 passively traps nematodes, 
penetrates the nematode cuticle and kills them within 4-8 hours, 
occupies the nematode body with hyphae within 20-36 hours, and consumes 
nematodes within 48 hours, thus breaking the infection excretion and 
reinfection cycle of nematodes. Duddingtonia flagrans strain IAH 1297's 
use as a feed-through nematicide comes as growing anthelmintic 
(antiparasitic drug) resistance and general lack of new drug options to 
treat affected animals is becoming a concern.

B. Microbial Pesticide Toxicology Data Requirements

    All applicable mammalian toxicology data requirements supporting 
the request for an exemption from the requirement of a tolerance for 
residues of Duddingtonia flagrans strain IAH 1297 in or on all food 
commodities have been fulfilled with data submitted by the petitioner 
or data waiver requests that have been granted by EPA. The toxicity 
tests (acute oral and dermal) and the primary dermal irritation test 
that address potential routes of exposure to the active ingredient are 
all classified in Toxicity Category IV (see section II of Ref. 3) and 
reveal no toxicity or irritation attributed to Duddingtonia flagrans 
strain IAH 1297. Moreover, during typical toxicity/pathogenicity 
testing done with microbial pesticides, Duddingtonia flagrans strain 
IAH 1297 showed no toxicity, pathogenicity, or infectivity via the 
pulmonary route of exposure. The conclusions and classifications from 
all toxicological information associated with the active ingredient and 
submitted by the petitioner are briefly described below.
    1. Acute oral toxicity--rat (Harmonized Guideline 870.1100; Master 
Record Identification Number (MRID) No. 503887-01). An acceptable acute 
oral toxicity study demonstrated that Duddingtonia flagrans strain IAH 
1297 is not toxic to female rats when dosed via the oral route at 5,000 
milligrams per kilogram (mg/kg) of bodyweight. The oral median lethal 
dose (LD50), which is a statistically derived single dose 
that can be expected to cause death in 50% of test animals, was greater 
than 5,000 mg/kg of bodyweight for female rats (Toxicity Category IV). 
(Refs. 1 and 2).
    2. Acute oral toxicity/pathogenicity (Harmonized Guideline 
885.3050; MRID Nos. 501117-14 and 501117-27). An acceptable scientific 
rationale was submitted by the petitioner; therefore, EPA waived acute 
oral toxicity/pathogenicity testing for Duddingtonia flagrans strain 
IAH 1297. An acute oral toxicity study conducted on female rats (MRID 
No. 503887-01) demonstrated that Duddingtonia flagrans strain IAH 1297 
was not toxic (LD50 greater than 5,000 mg/kg; Toxicity 
Category IV). Further, field studies were conducted on animal groups in 
Australia under direction of veterinarians. A 56-day study using young 
cattle demonstrated that a test substance containing Duddingtonia 
flagrans strain IAH 1297 had no discernible health effects when given 
with feed at 125 grams per 100 kilograms of bodyweight per day 
(representing 10X the label use rate). A 42-day study using Merino ewes 
had no findings attributable to treatment with a test substance 
containing Duddingtonia flagrans strain IAH 1297, and both groups had 
statistically similar weight gains throughout at 1 kilogram per group 
per day (representing 5X the label use rate). A 56-day study using 
horses demonstrated that a test substance containing Duddingtonia 
flagrans strain IAH 1297 had no discernible health effects when given 
with feed at 1 gram per kilogram bodyweight per day (representing 10X 
the label use rate). No signs of any infection were observed during 
these lengthy studies. EPA believes these data, when taken together, 
indicate that this fungus would not be toxic, infective, and/or 
pathogenic through the oral route of exposure and that further testing 
is not necessary. (Refs. 1 and 2).
    3. Acute pulmonary toxicity/pathogenicity--rat (Harmonized 
Guideline 885.3150; MRID Nos. 501117-

[[Page 19970]]

15, 501117-16, 505317-00, and 505318-00). An acceptable acute pulmonary 
toxicity/pathogenicity study performed with Duddingtonia flagrans 
strain IAH 1297 did not induce signs of toxicity, infectivity, or 
pathogenicity when administered to rats as a single, intratracheal dose 
of 5.8 x 10\4\ spores per animal. Additionally, clearance was 
established by day 42 of the test. (Refs. 1, 2, and 4).
    4. Acute injection toxicity/pathogenicity (Harmonized Guideline 
885.3200; MRID No. 501117-17). An acceptable scientific rationale was 
submitted by the petitioner; therefore, EPA waived acute injection 
toxicity/pathogenicity testing for Duddingtonia flagrans strain IAH 
1297. Intratracheal pulmonary administration of the highest possible 
dose of Duddingtonia flagrans strain IAH 1297 did not show any sign of 
infection or pathogenicity (MRID No. 501117-16). Lengthy oral dosing of 
cattle, sheep, and horses demonstrated no effects at doses of 5-10X the 
label use rates (MRID No. 501117-27), and an oral dose of 5,000 mg/kg 
of bodyweight to female rats also demonstrated no effects (MRID No. 
503887-01). Further, injection is expected to result in minimal 
breakdown of spores, and the relatively large size of the spores makes 
injection testing impractical. The lack of growth when Duddingtonia 
flagrans strain IAH 1297 was tested at 37[deg]C (oral dosing) also 
allays the need to test infectivity and pathogenicity by the injection 
route. Duddingtonia flagrans strain IAH 1297 has not shown any ability 
to germinate or grow when mammals were exposed by various other routes, 
and injection of these large spores is not expected to result in 
infection even if possible to perform the test. Thus, EPA believes 
these data and information, when taken together, indicate that this 
fungus would not be toxic, infective, and/or pathogenic through the 
injection route of exposure and that further testing is not necessary. 
(Refs. 1 and 2).
    5. Acute dermal toxicity--rat (Harmonized Guideline 870.1200; MRID 
No. 501113-05). An acceptable acute dermal toxicity study conducted 
using a test substance containing Duddingtonia flagrans strain IAH 1297 
demonstrated that the fungus was not toxic to rats when dosed at 5,000 
mg/kg of bodyweight for 24 hours to a body surface area of 
approximately 10 percent. Following exposure, animals were observed for 
14 days. All animals survived, gained weight, appeared active and 
healthy, and had no signs of dermal irritation throughout the study. No 
observable abnormalities were found in any animal at necropsy. The 
dermal LD50 for male and female rats combined was greater 
than 5,000 mg/kg of bodyweight (Toxicity Category IV). (Refs. 1 and 2).
    6. Primary dermal irritation--rabbit (Harmonized Guideline 
870.2500; MRID No. 501113-07). An acceptable primary dermal irritation 
study conducted using a test substance containing Duddingtonia flagrans 
strain IAH 1297 demonstrated that the fungus was non-irritating to the 
skin of rabbits. No dermal erythema, edema, or irritation was noted on 
any animal during the study. The primary irritation index was 0.0, and 
all animals gained weight normally during the study (Toxicity Category 
IV). (Refs. 1 and 2).

IV. Aggregate Exposure

    In examining aggregate exposure, FFDCA section 408 directs EPA to 
consider available information concerning exposures from the pesticide 
residue in food and all other non-occupational exposures, including 
drinking water from ground water or surface water and exposure through 
pesticide use in gardens, lawns, or buildings (residential and other 
indoor uses).

A. Dietary Exposure (Refs. 1 and 2)

    1. Food exposure. The proposed use of Duddingtonia flagrans strain 
IAH 1297 is as a feed-through product for grazing animals such as 
sheep, goats, cattle, horses, deer, alpacas and zoo animals. As 
Duddingtonia flagrans is naturally present in soils and commonly found 
in various plant materials, it is likely that grazing animals have 
natural background exposure to the fungus. No adverse effects have been 
reported as a result of these types of exposures. Studies performed 
with Duddingtonia flagrans strain IAH 1297 have not shown that this 
strain has the ability to germinate or grow when mammals are exposed by 
various routes, including the oral route. Further, no foodborne disease 
outbreaks or cases of mammalian toxin production from Duddingtonia 
flagrans have been reported. As a result, dietary exposure to 
Duddingtonia flagrans strain IAH 1297 through agricultural commodities 
is not anticipated from use of the pesticide products as the spores 
and/or components of the spores are unlikely to remain in the treated 
animals. Should Duddingtonia flagrans strain IAH 1297 be present in 
food, however, supporting toxicological data and information indicate 
that no toxicity, pathogenicity, or infectivity is likely to occur with 
this type of exposure resulting from the use of this microbial 
pesticide when applied in accordance with label directions and good 
agricultural practices.
    2. Drinking water exposure. Since Duddingtonia flagrans is 
naturally present in the environment and Duddingtonia flagrans strain 
IAH 1297 will be present in the feces of treated animals, exposure to 
surface and possibly groundwater can be expected. Water treatment 
processes should remove any Duddingtonia flagrans or Duddingtonia 
flagrans strain IAH 1297 present in these water sources, and no adverse 
effects have been reported from exposure to Duddingtonia flagrans 
through drinking water. As a result, dietary exposure to Duddingtonia 
flagrans strain IAH 1297 through drinking water is not anticipated from 
use of the pesticide products as the spores and/or components of the 
spores are unlikely to survive the water treatment process. Should 
Duddingtonia flagrans strain IAH 1297 be present in water, however, 
supporting toxicological data and information indicate that no 
toxicity, pathogenicity, or infectivity is likely to occur with this 
type of exposure resulting from the use of this microbial pesticide 
when applied in accordance with label directions and good agricultural 
practices.

B. Other Non-Occupational Exposure

    The pesticide products containing Duddingtonia flagrans strain IAH 
1297 are proposed for agricultural use sites and zoos. As a result, 
residential exposures resulting from use of these products are not 
anticipated. Nevertheless, Duddingtonia flagrans strain IAH 1297 was 
not toxic or irritating by dermal exposure and was not toxic, 
infective, or pathogenic by pulmonary exposure. Further, the products 
are mixed into feed ingredients at 2-34.6% so it is not in pure form, 
and the spore size is at the upper end of the respirable range so human 
exposures to Duddingtonia flagrans strain IAH 1297 by inhalation from 
contact with animal feed supplements is unlikely.

V. Cumulative Effects From Substances With a Common Mechanism of 
Toxicity

    Section 408(b)(2)(D)(v) of FFDCA requires that, when considering 
whether to establish, modify, or revoke a tolerance, EPA consider 
``available information concerning the cumulative effects of [a 
particular pesticide's] . . . residues and other substances that have a 
common mechanism of toxicity.''
    Duddingtonia flagrans strain IAH 1297 is not toxic and does not 
have a common mechanism of toxicity with other substances. 
Consequently, FFDCA section 408(b)(2)(D)(v) does not apply.

[[Page 19971]]

VI. Determination of Safety for U.S. Population, Infants and Children

A. U.S. Population

    For all of the reasons discussed previously, EPA concludes that 
there is reasonable certainty that no harm will result to the U.S. 
population, including infants and children, from aggregate exposure to 
residues of Duddingtonia flagrans strain IAH 1297. This includes all 
anticipated dietary exposures and all other exposures for which there 
is reliable information.

B. Infants and Children

    FFDCA section 408(b)(2)(C) provides that EPA shall apply an 
additional tenfold (10X) margin of safety for infants and children in 
the case of threshold effects to account for prenatal and postnatal 
toxicity and the completeness of the database on toxicity and exposure, 
unless EPA determines based on reliable data that a different margin of 
safety will be safe for infants and children. This additional margin of 
safety is commonly referred to as the Food Quality Protection Act 
Safety Factor. In applying this provision, EPA either retains the 
default value of 10X or uses a different additional safety factor when 
reliable data available to EPA support the choice of a different 
factor. As discussed above, EPA has concluded that Duddingtonia 
flagrans strain IAH 1297 is not toxic, pathogenic, or infective to 
mammals, including infants and children. Because there are no threshold 
levels of concern to infants, children, and adults when Duddingtonia 
flagrans strain IAH 1297 is used in accordance with label directions 
and good agricultural practices, EPA concludes that no additional 
margin of safety is necessary to protect infants and children.

VII. Other Considerations

A. Analytical Enforcement Methodology

    An analytical method is not required for enforcement purposes 
because EPA is establishing an exemption from the requirement of a 
tolerance without any numerical limitation.

B. Revisions to Requested Tolerance Exemption

    One modification has been made to the requested tolerance 
exemption. EPA is changing ``in or on all raw and processed 
agricultural commodities'' to ``in or on all food commodities'' to 
align with the terminology the Agency currently uses when establishing 
tolerance exemptions for residues of other like active ingredients.

VIII. Conclusions

    EPA concludes that there is a reasonable certainty that no harm 
will result to the U.S. population, including infants and children, 
from aggregate exposure to residues of Duddingtonia flagrans strain IAH 
1297. Therefore, an exemption from the requirement of a tolerance is 
established for residues of Duddingtonia flagrans strain IAH 1297 in or 
on all food commodities when used in accordance with label directions 
and good agricultural practices.

X. Statutory and Executive Order Reviews

    This action establishes a tolerance exemption under FFDCA section 
408(d) in response to a petition submitted to EPA. The Office of 
Management and Budget (OMB) has exempted these types of actions from 
review under Executive Order 12866, entitled ``Regulatory Planning and 
Review'' (58 FR 51735, October 4, 1993). Because this action has been 
exempted from review under Executive Order 12866, this action is not 
subject to Executive Order 13211, entitled ``Actions Concerning 
Regulations That Significantly Affect Energy Supply, Distribution, or 
Use'' (66 FR 28355, May 22, 2001), or Executive Order 13045, entitled 
``Protection of Children from Environmental Health Risks and Safety 
Risks'' (62 FR 19885, April 23, 1997). This action does not contain any 
information collections subject to OMB approval under the Paperwork 
Reduction Act (PRA), 44 U.S.C. 3501 et seq., nor does it require any 
special considerations under Executive Order 12898, entitled ``Federal 
Actions to Address Environmental Justice in Minority Populations and 
Low-Income Populations'' (59 FR 7629, February 16, 1994).
    Since tolerances and exemptions that are established on the basis 
of a petition under FFDCA section 408(d), such as the tolerance 
exemption in this action, do not require the issuance of a proposed 
rule, the requirements of the Regulatory Flexibility Act (RFA) (5 
U.S.C. 601 et seq.) do not apply.
    This action directly regulates growers, food processors, food 
handlers, and food retailers, not States or tribes. As a result, this 
action does not alter the relationships or distribution of power and 
responsibilities established by Congress in the preemption provisions 
of FFDCA section 408(n)(4). As such, EPA has determined that this 
action will not have a substantial direct effect on States or tribal 
governments, on the relationship between the national government and 
the States or tribal governments, or on the distribution of power and 
responsibilities among the various levels of government or between the 
Federal Government and Indian tribes. Thus, EPA has determined that 
Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 10, 
1999), and Executive Order 13175, entitled ``Consultation and 
Coordination with Indian Tribal Governments'' (65 FR 67249, November 9, 
2000), do not apply to this action. In addition, this action does not 
impose any enforceable duty or contain any unfunded mandate as 
described under Title II of the Unfunded Mandates Reform Act (UMRA) (2 
U.S.C. 1501 et seq.).
    This action does not involve any technical standards that would 
require EPA's consideration of voluntary consensus standards pursuant 
to section 12(d) of the National Technology Transfer and Advancement 
Act (NTTAA) (15 U.S.C. 272 note).

XI. Congressional Review Act

    Pursuant to the Congressional Review Act (5 U.S.C. 801 et seq.), 
EPA will submit a report containing this rule and other required 
information to the U.S. Senate, the U.S. House of Representatives, and 
the Comptroller General of the United States prior to publication of 
the rule in the Federal Register. This action is not a ``major rule'' 
as defined by 5 U.S.C. 804(2).
