Prior to passage of the Food Quality Protection Act (FQPA) of 1996, the division of jurisdiction over antimicrobials used in food-related applications between the Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA), was governed by the provisions of the Federal Food, Drug and Cosmetic Act (FFDCA). FQPA modified FFDCA, and in the process transferred to EPA regulatory jurisdiction over several antimicrobial substances that had once been under FDA jurisdiction and made compliance with the new food safety criteria a requirement for pesticide registration.
In the two years after FQPA enactment, EPA and FDA held extensive discussions on their respective legal authorities pre- and post-FQPA. As a result, on October 9, 1998, the two agencies issued a joint notice of policy interpretation announcing their plans for implementing the jurisdictional shifts enacted two years before. See 63 Fed. Reg. 54532 (1998). The joint notice also outlined planned changes to the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) definition of "pest" to exclude more microorganisms as well as additional transfers of jurisdiction back to FDA under FFDCA section 201 (q) (3).
Subsequently, however, the agencies have decided that much of their transition plans have been rendered unnecessary by the Antimicrobial Regulation Technical Corrections Act (ARTCA), which President Clinton signed into law on October 30, 1998. See Antimicrobial Regulation Technical Corrections Act of 1998, Pub. L. No. 105-324, 112 Stat. 3035; see also Antimicrobial Regulation Technical Corrections Act Becomes Law; Jurisdictional Chaos Created by FQPA. ARTCA amended the FFDCA section 201 (q) (1) definition of "pesticide chemical." According to an EPA draft Federal Register notice dated December, 1998, ARTCA essentially accomplished EPA's and FDA's planned regulatory approach as set forth in the October 9, 1998 Federal Register notice, and the joint notice will be abandoned.
This position was confirmed on July 27, 1999, when FDA announced the availability of a guidance document intended to clarify FDAs jurisdiction over antimicrobials used in food or that may become a component of food as a result of their intended use. The document, Antimicrobial Food Additives Guidance, also discusses the food-related uses of antimicrobial products that ARTCA excluded from FDAs regulatory authority. It describes, consistent with the interpretation set forth in the October 9, 1998 Federal Register Notice, EPAs jurisdiction over certain pesticide inert ingredients, and EPAs intent to transfer responsibility to FDA for certain inerts used as food-contact articles.
The guidance also defines certain terms, such as "processed food" and "food processing facility," that are important to the delineation of FDAs and EPAs regulatory authority. Briefly, processing alters the general state of a raw agricultural commodity (RAC), defined in FFDCA as "any food in its raw or natural state, including all fruits that are washed, colored, or otherwise treated in their unpeeled natural form prior to marketing," while non-processing operations merely isolate or separate the RAC from foreign objects or other parts of the plant. Therefore, RACs that have been canned, frozen, cooked, dried (unless the purpose for drying is to facilitate transportation or storage of the RAC prior to processing) pasteurized, homogenized, irradiated, milled, ground, chopped, sliced, cut, peeled, skinned, eviscerated, quartered, or harvested (e.g., seafood) are considered processed food. RACs that simply have been washed, colored, waxed, hydro-cooled, refrigerated, shelled (e.g., nuts), ginned (e.g., cotton), or have had their leaves, stems, or husks removed maintain their status as RACs.
A "food processing facility" is simply a facility where food is subject to activities that constitute processing. Included within this meaning are facilities where meat and poultry are slaughtered, where eggs are washed and treated such that they are changed from RACs to processed food, and where post-harvest activities are conducted on sea food. The term also includes commercial fishing vessels and retail food establishments.
An understanding of these definitions is important in determining whether EPA or FDA possesses regulatory jurisdiction over pesticides and their residues on food. The bottom line is that, for the foreseeable future, residues on food of antimicrobial products which require registration as pesticides will adulterate food unless: (1) an appropriate FDA status is established for the residue when the antimicrobial is used on a RAC in a food processing facility (defined at 3 in Table); or (2) an appropriate tolerance or exemption from tolerance is in place for a pesticide chemical in other uses. Microorganisms on processed foods continue to be exempt from the definition of "pest;" antimicrobials intended to affect such "non-pests" are not pesticides and still will only require FDA clearance.
The following table provides a summary of post-ARTCA EPA and FDA jurisdiction over pesticide products and their residue on food, as compared to the pre-FQPA jurisdictional allocation. Note that some products which have not previously required pesticide registration will now apparently be required to obtain registrations. This appears to be a consequence of EPA rethinking prior positions, since FQPA, per se, did not amend the definition of "pest" other than with respect to the use of liquid chemical sterilants on certain medical devices. The table is set up so that each cell contains two entries. The entry to the left of the "/" identifies the agency with jurisdiction for the antimicrobial product which moves in commerce. The entry to the right of the "/" identifies the agency with jurisdiction of any required pre-clearance of residues. If EPA has jurisdiction over the product, then the product is a pesticide and registration is required. If FDA has product jurisdiction, no preclearance of the specific product is required; any product which complies with applicable regulations such that its use will not cause food to be adulterated may be sold for such use in or on food as long as the product itself is not adulterated or misbranded.

Shaded boxes indicate that different agencies would be responsible for product registration and food safety. However, EPA may still be required to apply FQPA safety criteria before registering products (even though FDA has cleared the safety of potential residues under section 409 of the Federal Food Drug and Cosmetic Act (21 U.S.C. § 348)). Section 2(bb) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) provides that "[t]he term "unreasonable adverse effects on the environment" means . . . (2) a human dietary risk from residues that result from a use of a pesticide in or on any food inconsistent with the standard under section 408 of the Federal Food, Drug, and Cosmetic Act (21 U.S.C. 346a) . . ." 7 U.S.C. § 136(bb). EPA cannot register a product that poses an unreasonable adverse effect on the environment. On October 9, 1998, EPA published a Federal Register Notice which would eliminate the need to apply the 408 criteria to residues already found to be safe under section 409 by expanding the circumstances under which microorganisms would be excluded from the definition of "pest." See 63 Fed. Reg. 54,532 (1998). Current indications are that this approach has been abandoned and the allocation of jurisdiction created by ARTCA will remain the law for the foreseeable future.
! All changes in jurisdiction that EPA attributes to FQPA arguably result from EPA's non-codified decision to interpret the definition of the term "processed food" for purposes of its regulatory definition of the term "pest" more narrowly than the statutory definition of "processed food" contained in FQPA; presumably enforcement discretion will permit unregistered products to remain on the market in those situations where this interpretation requires registration of previously unregistered products. EPA has not spoken on this issue, nor has it initiated any enforcement actions against historical FDA regulated products that are now unregistered pesticides.
* Most products used for this purpose already have EPA registrations because they typically have uses that do not involve food contact.
