2022-09939. Practices To Prevent Unsafe Contamination of Animal Feed From Drug Carryover; Draft Guidance for Industry; Availability

AGENCY:

Food and Drug Administration, HHS.

ACTION:

Notice of availability.

SUMMARY:

The Food and Drug Administration (FDA, Agency, or we) is announcing the availability of a draft guidance for industry #272 entitled “Practices to Prevent Unsafe Contamination of Animal Feed from Drug Carryover.” We are issuing this draft guidance to describe practices that medicated feed manufacturers can use to prevent unsafe contamination from drug carryover into a non-medicated animal feed or an animal feed containing a different approved new animal drug. Unsafe contamination of animal feed from drug carryover can pose a risk to human and animal health. When finalized, this guidance will replace Compliance Policy Guides (CPGs) Sec. 680.500 and 680.600.

DATES:

Submit either electronic or written comments on the draft guidance by August 8, 2022 to ensure that the Agency considers your comment on this draft guidance before it begins work on the final version of the guidance.

ADDRESSES:

You may submit comments on any guidance at any time as follows:

SUPPLEMENTARY INFORMATION:

I. Background

FDA is announcing the availability of a draft guidance for industry #272 entitled “Practices to Prevent Unsafe Contamination of Animal Feed from Drug Carryover.” This draft guidance contains much of the information found in the CPGs Sec. 680.500 “Unsafe Contamination of Animal Feed from Drug Carryover” and 680.600 “Sequencing as a Means to Prevent Unsafe Drug Contamination in the Production, Storage, and Distribution of Feeds” but includes updates and additional information. We intend to withdraw the CPGs after this guidance is finalized. Drug carryover generally occurs when a drug used in the manufacture of a batch of medicated feed, for which the drug is approved, gets inadvertently included in a subsequent batch of: (1) A non-medicated feed, (2) a different medicated feed for which the drug is not approved ( e.g., medicated feed for another species), or (3) a medicated feed that contains the same drug that can result in a higher drug level than is stated on the labeling. This carryover can occur for multiple reasons, including the use of the same equipment to manufacture both medicated and non-medicated feed, inadequate cleanout practices for manufacturing and distribution equipment between sequential batches, or human error.

We understand that an absolute avoidance of all batch-to-batch drug carryover may not be possible. However, measures can be implemented to avoid unsafe contamination of animal feed from drug carryover. In this draft guidance, unsafe contamination of an animal feed refers to a degree of contamination, by a drug approved for a medicated feed use, that poses an unacceptable risk to human or animal health. Human health may be at risk if humans consume a product derived from animals that have consumed animal feed contaminated from drug carryover and there is drug residue in the edible tissues of that animal ( e.g., milk, meat, or eggs). Unsafe contamination from drug carryover in animal feed can impact animal health when an animal consumes the contaminated feed, e.g., horses consuming feed contaminated with the drug monensin. Horses are sensitive to ionophore drugs like monensin, and ingestion can result in severe illness or death.

Our regulation “Current Good Manufacturing Practice for Medicated Feeds,” 21 CFR part 225, contains requirements for equipment cleanout procedures to avoid unsafe contamination of feeds with drugs (see 21 CFR 225.65 and 225.165). In this guidance, we provide information on some ways to comply with these requirements to help prevent unsafe contamination of animal feed from drug carryover.

This level 1 draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the current thinking of FDA on some practices that can be used in feed mills manufacturing medicated feed to prevent unsafe contamination of animal feed from drug carryover. It does not establish any rights for any person and is not binding on FDA or the public. You can use an alternative approach if it satisfies the requirements of the applicable statutes and regulations.

II. Paperwork Reduction Act of 1995

FDA tentatively concludes that this draft guidance contains no collection of information. Therefore, clearance by the Office of Management and Budget under the Paperwork Reduction Act of 1995 is not required.
