Bacteriophage of Clavibacter Michiganensis Subspecies 
Michiganensis; 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 lytic bacteriophage of Clavibacter 
michiganensis subspecies michiganensis produced in Clavibacter 
michiganensis subspecies michiganensis in or on tomato when applied as 
a bactericide in accordance with good agricultural practices. On behalf 
of OmniLytics, Inc., Interregional Research Project Number 4 (IR-4) 
submitted a petition to EPA under the Federal Food, Drug, and Cosmetic 
Act (FFDCA) requesting an exemption from

[[Page 66188]]

the requirement of a tolerance. This regulation eliminates the need to 
establish a maximum permissible level for residues of lytic 
bacteriophage of Clavibacter michiganensis subspecies michiganensis 
produced in Clavibacter michiganensis subspecies michiganensis under 
the FFDCA.

DATES: This regulation is effective October 26, 2011. Objections and 
requests for hearings must be received on or before December 27, 2011,

II. Background and Statutory Findings

    In the Federal Register of September 23, 2009 (74 FR 48556) (FRL-
8434-7), EPA issued a notice pursuant to section 408(d)(3) of FFDCA, 21 
U.S.C. 346a(d)(3), announcing the filing of a pesticide tolerance 
petition (PP 9E7552) by IR-4, Rutgers University, 500 College Rd. East, 
Suite 201W, Princeton, NJ 08540 (on behalf of OmniLytics, Inc., 9100 
South 500 West, Sandy, UT 84070). The petition requested that 40 CFR 
part 180 be amended by establishing an exemption from the requirement 
of a tolerance for residues of bacteriophage of Clavibacter 
michiganensis subspecies michiganensis. This notice referenced a 
summary of the petition prepared by the petitioner, IR-4, which is 
available in the docket via http://www.regulations.gov. There were no 
comments received in response to the notice of filing.
    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 section 408(c)(2)(B) of FFDCA, in 
establishing or maintaining in effect an exemption from the requirement 
of a tolerance, EPA must take into account the factors set forth in 
section 408(b)(2)(C) of FFDCA, which require EPA to give special 
consideration to exposure of infants and children to the pesticide 
chemical residue in establishing a tolerance exemption and to ``ensure 
that there is a reasonable certainty that no harm will result to 
infants and children from aggregate

[[Page 66189]]

exposure to the pesticide chemical residue. * * *''
    Additionally, section 408(b)(2)(D) of FFDCA 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, EPA determines the 
toxicity of pesticides. Second, EPA examines exposure to the pesticide 
through food, drinking water, and through other exposures that occur as 
a result of pesticide use in residential settings.

III. Toxicological Profile

    Consistent with section 408(b)(2)(D) of FFDCA, EPA has reviewed the 
available scientific data and other relevant information in support of 
this action and considered its validity, completeness, and reliability 
and the relationship of this information to human risk. EPA has also 
considered available information concerning the variability of the 
sensitivities of major identifiable subgroups of consumers, including 
infants and children.

A. Bacteriophage Overview

    Bacteriophage, the most abundant group of biological entities on 
the planet, are naturally occurring viruses that are found in soil and 
water and in association with plants and animals, including humans 
(Refs. 1 through 8). Bacteriophage are obligate parasites of bacteria, 
which means they attach to, infect, and reproduce in bacteria, and are 
host-specific for bacteria, with specific bacteriophage attacking only 
one bacterial species and most frequently only one strain within a 
bacterial species (Refs. 9 through 11). As such, bacteriophage do not 
attack other beneficial bacteria. In addition, there is no evidence for 
bacteriophage infecting any other life form, including humans, except 
bacteria (Refs. 7, 12, and 13). Humans and other animals commonly 
consume bacteriophage as they are abundantly found in water, on plant 
surfaces, and in foods such as ground beef, pork sausage, chicken, 
oysters, cheese, mushrooms, and broccoli (Refs. 3, 4, and 14 through 
19). In addition, bacteriophage are common commensals of the human gut 
and likely play an important role in regulating populations of various 
bacteria in the gastrointestinal tract (Ref. 7). As cited in public 
literature, bacteriophage have been used for more than 80 years as 
therapeutic agents with no ill effects and are active against bacteria 
that cause many infections and human diseases (Refs. 7, 20, and 21).
    Since 2005, bacteriophage have also been used in a pesticide 
product (Agriphage; EPA Reg. No. 67986-1), without reported incidents, 
to control particular bacterial diseases (Xanthomonas campestris pv. 
vesicatoria and Pseduomonas syringae pv. tomato) of tomato and pepper. 
In conjunction with registration of the aforementioned pesticide 
product, EPA established an exemption from the requirement of a 
tolerance for residues of bacteriophage of Xanthomonas campestris pv. 
vesicatoria and Pseud[oacute]monas syringae pv. tomato in or on tomato 
and pepper (see the Federal Register of December 28, 2005 (70 FR 76704) 
(FRL-7753-6)). Much like the previously registered bacteriophage, 
OmniLytics, Inc. is proposing that bacteriophage of Clavibacter 
michiganensis subspecies michiganensis be applied as a pesticide for a 
very limited use-to control bacterial canker disease on tomato.

B. Microbial Pesticide Toxicology Data Requirements

    All mammalian toxicology data requirements supporting the request 
for an exemption from the requirement of a tolerance for residues of 
bacteriophage of Clavibacter michiganensis subspecies michiganensis in 
or on tomato have been fulfilled with submission of valid studies from 
the public literature (Refs. 22 and 23).
    As mentioned in Unit III.A., bacteriophage are viruses that only 
infect specific bacteria, a basic fact supported by both information 
presented in public literature and the absence of reported adverse 
effects to humans even with commonplace exposure to bacteriophage. 
Literature submitted established that bacteriophage have been used 
historically and through modern times in lieu of or to assist the 
action of antibiotics. Clinical uses encompass all manner of 
administration from injection/intravenous and surgical wound 
applications to topical and ingestible preparations. There have been no 
reports of adverse effects from such administrations and in other 
similar cases using controlled scientific studies. Also submitted were 
literature citations showing that bacteriophage are common and abundant 
in soils, are in a wide range of plant materials, and are generally 
present in high numbers in the environment (e.g., up to 1010 plaque-
forming units (PFU) per liter may be found in non-polluted waters). Yet 
again, no adverse effects to humans have been reported with these types 
of potential exposure. Moreover, bacteriophage presence reported in 
foods and feeds ranges from 101 to 105 PFU/100 grams (g) of meat and up 
to 107 PFU/100 g of cheese without any known harmful effects after 
consumption of such materials. Finally, the petitioner noted that, 
during an extensive history of bacteriophage laboratory and pesticidal 
usage, adverse reports in the literature have not been documented and 
episodes of hypersensitivity have not occurred.
    Because bacteriophage are obligate bacterial parasites and are not 
known to infect humans, the only human health risk associated with use 
of bacteriophage of Clavibacter michiganensis subspecies michiganensis 
as a bactericide is potential for acquisition and production of 
microbial toxins. This acquisition occurs through lysogeny, which is 
when bacteriophage integrate into the genome of toxigenic bacterial 
host strains and pick up and transmit those genetic traits to other 
bacteria that otherwise would not produce toxic substances. Therefore, 
bacteriophage of Clavibacter michiganensis subspecies michiganensis 
that meet the following two conditions do not present this risk issue:
    1. Bacteriophage produced in Clavibacter michiganensis subspecies 
michiganensis, which has been sequenced and determined to be an 
atoxigenic host bacteria, and
    2. Bacteriophage possessing the capability to lyse host bacteria, 
i.e., completely destroy host cells during the viral production 
process, which precludes genetic transfer of possible toxins to other 
bacteria (Ref. 22).

IV. Aggregate Exposure

    In examining aggregate exposure, section 408 of FFDCA 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

    1. Food exposure. Published literature submitted by the petitioner, 
as well as other publicly available literature, indicate that 
bacteriophage are commonly associated with food and are therefore 
regularly consumed by humans. According to Ackermann (1997), these 
viruses have been found in association with ``buds, leaves, root 
nodules (leguminous plants), roots,

[[Page 66190]]

rotting fruit, seeds, stems, and straw; crown gall tumors * * * healthy 
or diseased alfalfa, barley, beans, broccoli, Brussels sprouts, 
buckwheat, clover, cotton, cucumber, lucerne, mulberry, oats, peas, 
peach trees, radish, rutabaga, ryegrass, rye, timothy, tobacco, 
tomatoes, [and] wheat'' (Ref. 14). Moreover, bacteriophage have been 
isolated from a wide range of food products, including ground beef, 
pork sausage, chicken, farmed freshwater fish, common carp, marine 
fish, oil sardines, raw skim milk, and cheese (Refs. 15, 16, and 24 
through 27). In fact, several studies have suggested that 100% of the 
ground beef and chicken meat sold at retail stores contain various 
levels of bacteriophage. For instance, bacteriophage were recovered 
from 100% of examined fresh chicken and pork sausage samples and from 
33% of delicatessen meat samples analyzed; the levels ranged from 3.3 x 
1010 to 4.4 x 1010 PFU/100 g of fresh chicken, up to 3.5 x 1010 PFU/100 
g of fresh pork, and up to 2.7 x 1010 PFU/100 g of roast turkey breast 
samples (Ref 16). Other studies similarly showed the widespread 
occurrence of bacteriophage in certain foods:
    a. 38 bacteriophage-host systems were isolated from 22 of 45 
refrigerated products (Ref 27);
    b. Bacteriophage infecting fire blight pathogen (Erwinia amylovora) 
were isolated from apple, pear, and raspberry tissues and from soil 
samples collected at sites displaying fire blight symptoms (Ref 5); and
    c. Shellfish, which filter large quantities of seawater, 
concentrated both bacteria and bacteriophage (Ref 6).
    Because lytic bacteriophage of Clavibacter michiganensis subspecies 
michiganensis produced in Clavibacter michiganensis subspecies 
michiganensis are intended to be applied to tomatoes, it is likely that 
dietary exposure will occur; however, no adverse effects are expected 
to occur. Despite constant and direct food exposure to bacteriophage 
(examples provided in the preceding paragraph and in Unit III.), no 
adverse effects to humans have been reported in publicly available 
literature. Indeed, no such effects are expected given that 
bacteriophage, including the one at issue in this action, are not 
capable of infecting eukaryotic cells and are host specific, attacking 
only bacteria.
    2. Drinking water exposure. Published literature submitted by the 
petitioner, as well as other publicly available literature, indicate 
that, much like food, bacteriophage are commonly associated with water 
and are therefore regularly consumed by humans. According to Demuth et 
al. (1993), ``Bacteriophage * * * have been isolated from all types of 
bacteria and from virtually any aquatic or terrestrial habitat where 
bacteria can exist. However, only in the last few years has it been 
recognized that viruses (phage) are extremely abundant in ocean and 
fresh water and may exceed the concentration of bacteria by up to 100-
fold'' (Ref. 3). Other studies showed that bacteriophage of Erwinia 
carotovora and Erwinia ananas were isolated from certain freshwater 
lakes in Florida and Texas (Ref. 4) and that coliphage were present in 
some samples of drinking water (Ref 28).
    When lytic bacteriophage of Clavibacter michiganensis subspecies 
michiganensis produced in Clavibacter michiganensis subspecies 
michiganensis are applied to tomato as a bactericide in accordance with 
good agricultural practices, exposure of humans to residues of these 
bacteriophage in consumed drinking water may occur. Although lytic 
bacteriophage of Clavibacter michiganensis subspecies michiganensis 
produced in Clavibacter michiganensis subspecies michiganensis are not 
expected to reach surface water because the proposed use patterns do 
not include direct application to aquatic sites, it is possible that 
this microbial pest control agent could make it into ground water. 
Nonetheless, if oral exposure to lytic bacteriophage of Clavibacter 
michiganensis subspecies michiganensis produced in Clavibacter 
michiganensis subspecies michiganensis occurs through consumed drinking 
water (e.g., due to surface water contamination by microbial pesticide 
spray drift or runoff or contact with ground water), for the many 
reasons enumerated in Unit III. and Unit IV.A.1., EPA concludes there 
is reasonable certainty that this type of drinking water exposure, or 
any level of drinking water exposure for that matter, will not result 
in harm to humans.

B. Other Non-Occupational Exposure

    Dermal and inhalation non-occupational exposures to lytic 
bacteriophage of Clavibacter michiganensis subspecies michiganensis 
produced in Clavibacter michiganensis subspecies michiganensis are not 
expected as all proposed pesticide applications will take place in 
distinct agricultural settings. Even if dermal and inhalation non-
occupational exposures were to occur inadvertently (e.g., through spray 
drift) or due to an eventual expansion of use sites, such exposures 
would not be of concern given the information presented in Unit III. 
and Unit IV.A.

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 exemption, 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 has not found lytic bacteriophage of Clavibacter michiganensis 
subspecies michiganensis produced in Clavibacter michiganensis 
subspecies michiganensis to share a common mechanism of toxicity with 
any other substances, and lytic bacteriophage of Clavibacter 
michiganensis subspecies michiganensis produced in Clavibacter 
michiganensis subspecies michiganensis do not appear to produce a toxic 
metabolite against the target pest. For the purposes of this tolerance 
action, therefore, EPA has assumed that lytic bacteriophage of 
Clavibacter michiganensis subspecies michiganensis produced in 
Clavibacter michiganensis subspecies michiganensis do not have a common 
mechanism of toxicity with other substances. Therefore, section 
408(b)(2)(D)(v) of the FFDCA does not apply. For information regarding 
EPA's efforts to determine which chemicals have a common mechanism of 
toxicity and to evaluate the cumulative effects of such chemicals, see 
EPA's Web site at http://www.epa.gov/pesticides/cumulative.

VI. Determination of Safety for United States (U.S.) Population, 
Infants and Children

    FFDCA section 408(b)(2)(C) provides that EPA shall assess the 
available information about consumption patterns among infants and 
children, special susceptibility of infants and children to pesticide 
chemical residues, and the cumulative effects on infants and children 
of the residues and other substances with a common mechanism of 
toxicity. In addition, 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 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

[[Page 66191]]

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 previously discussed in Unit III. and Unit IV., humans, 
including infants and children, have been exposed to bacteriophage 
through food and water, where they are commonly found, and through 
decades of therapeutic use with no known or reported adverse effects. 
Based on this, as well as all the other reasons enumerated repeatedly 
in this unit, 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 the residues of lytic 
bacteriophage of Clavibacter michiganensis subspecies michiganensis 
produced in Clavibacter michiganensis subspecies michiganensis. Such 
exposure includes all anticipated dietary exposures and all other 
exposures for which there is reliable information. EPA has arrived at 
this conclusion because, considered collectively, the public literature 
available on bacteriophage, including the one at issue in this action, 
do not demonstrate toxic, pathogenic, and/or infective potential to 
mammals. Thus, there are no threshold effects of concern and, as a 
result, an additional margin of safety is not necessary.

VII. Other Considerations

A. Analytical Enforcement Methodology

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

B. International Residue Limits

    In making its tolerance decisions, EPA seeks to harmonize U.S. 
tolerances with international standards whenever possible, consistent 
with U.S. food safety standards and agricultural practices. In this 
context, EPA considers the international maximum residue limits (MRLs) 
established by the Codex Alimentarius Commission (Codex), as required 
by FFDCA section 408(b)(4). The Codex Alimentarius is a joint U.N. Food 
and Agriculture Organization/World Health Organization food standards 
program, and it is recognized as an international food safety 
standards-setting organization in trade agreements to which the United 
States is a party. EPA may establish a tolerance that is different from 
a Codex MRL; however, FFDCA section 408(b)(4) requires that EPA explain 
the reasons for departing from the Codex level.
    The Codex has not established a MRL for lytic bacteriophage of 
Clavibacter michiganensis subspecies michiganensis produced in 
Clavibacter michiganensis subspecies michiganensis.

C. Revisions to Requested Exemption

    In its petition, the petitioner requested generally that the Agency 
issue an exemption from the requirement of a tolerance for residues of 
bacteriophage of Clavibacter michiganensis subspecies michiganensis in 
or on tomato. The petitioner's supporting materials indicated that the 
actual pesticide that would be used would be safe because the 
bacteriophage were lytic and produced in Clavibacter michiganensis 
subspecies michiganensis. The Agency believes both that these two 
conditions are necessary to make the safety finding and the petitioner 
was only requesting a narrow exemption; therefore, the Agency is 
modifying the tolerance exemption regulatory text to include such 
criteria.

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 lytic bacteriophage of 
Clavibacter michiganensis subspecies michiganensis produced in 
Clavibacter michiganensis subspecies michiganensis. Therefore, an 
exemption from the requirement of a tolerance is established for 
residues of lytic bacteriophage of Clavibacter michiganensis subspecies 
michiganensis produced in Clavibacter michiganensis subspecies 
michiganensis in or on tomato when applied as a bactericide in 
accordance with good agricultural practices.

X. Statutory and Executive Order Reviews

    This final rule establishes a tolerance exemption under section 
408(d) of FFDCA 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 final rule has been 
exempted from review under Executive Order 12866, this final rule 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 final rule 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 section 408(d) of FFDCA, such as the tolerance 
exemption in this final rule, 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 final rule 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 section 408(n)(4) of FFDCA. 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 final rule. In addition, this final rule 
does not impose any enforceable duty or contain any unfunded mandate as 
described under Title II of the Unfunded Mandates Reform Act of 1995 
(UMRA) (Pub. L. 104-4).
    This action does not involve any technical standards that would 
require EPA consideration of voluntary consensus standards pursuant to 
section 12(d) of the National Technology Transfer and Advancement Act 
of 1995 (NTTAA), Public Law 104-113, section 12(d) (15 U.S.C. 272 
note).

XI. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801 et seq., generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report to each House of the Congress and to 
the Comptroller General of the United States. 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 this final rule in the Federal 
Register. This final rule is not a ``major rule'' as defined by 5 
U.S.C. 804(2).
