Current Recommended Antimicrobial Products Withdrawal Times for U.S. Pork Intended for International Markets
Updated Withdrawal Times for Tetracycline (Feed-Grade/Water-Soluble) Products
A new pork trade certificate with Russia has been negotiated. This certificate sets guidelines for packers that are exporting to Russia. The Russian Product Verification Program (PVP) is a program to verify compliance with the Russian tetracycline standard. The purpose of the PVP program is to provide specific product requirements for marketing U.S. Pork and pork products to the Russian Federation under the USDA Export Verification Program. One of the product requirements is a 14-day withdrawal period for all soluble and feed-grade tetracycline products to satisfy Russia’s tetracycline maximum residue limit (MRL). Your packer may require some type of verification to show this withdrawal period is being met.
Important Note: Although the 14-day withdrawal period for tetracycline products (soluble and feed-grade) is to meet Russian import requirements, it is also the recommended guideline for all U.S. Pork exports. For more information, view the USDA’s Product Verification Program on Tetracycline Withdrawal.

Export Success Begins at Farm Level: Important Facts to Know
International markets around the world continue to provide a valuable outlet for U.S. Pork and pork products. For this reason, the federal government, along with the U.S. Meat Export Federation, National Pork Producers Council, the American Pork Export Trading Company and others, work to ensure export customers get a continuous supply of high-quality, safe pork.
The export chain, however, begins at the farm level—meaning every American producer plays an important role in producing this safe, nutritious, high-quality pork for the world’s growing population.
As part of the ongoing example of how U.S. producers show they care for their animals and the food they produce, they work with their veterinarians to follow the key guidelines associated with the proper use of animal health products.
This close working relationship, typically cited at the Veterinary-Client-Patient Relationship (VCPR) is critical to the ongoing success of U.S. pork exports. This is especially true as international markets evolve over time and may result in trading partners making changes in their requirements of purchasing U.S. Pork. Often, these changes are related to residue levels in meat or meat products, typically called Maximum Residue Levels (MRLs).
AASV Recommendations to Meet Export MRL of All Antimicrobials for U.S. Pork Exports
Background and Goals:
- Protection of export markets and consumer confidence is of critical importance to the pork industry
- Highest risk to these markets is from mass medication during the finishing period and in the breeding herd.
- Animal care and production may require administering products during the finishing phase or in the breeding herd.
- The National Pork Board’s product withdrawal database contains only products for which the manufacturer has supplied specific export MRL withdrawal information. Products without specific export MRL withdrawal information are not listed.
Recommendations:
- Use the best science available to ensure compliance with market specifications.
- If specific withdrawal times for a product have not been supplied by the manufacturer, the product will not be listed in the product/withdrawal database. If a product is not listed in the database, the AASV recommends not using that product during the finisher phase or in breeding animals. This includes proprietary and generic products.
- A generic product may have a different withdrawal time from its proprietary equivalent. Follow the specific product withdrawal recommendation.
- Follow the recommended product withdrawal to meet the export MRL requirements. Product withdrawal time is based on applying the product at the labeled dosage and route and duration of administration.
- If a compound is given by multiple routes of administration (example - given in the water, in the feed and/or by injection) simultaneously, withdrawal time may need to be extended. Contacting the product manufacturer(s) about appropriate withdrawal time to meet market expectations is recommended.
- Follow appropriate administration techniques.
- Includes location of injection site
- Includes volume of product within one injection site
- Any change in location, administration, volume or labeled directions constitutes extralabel use. There may not be specific withdrawal data available for extralabel use of specific products.
- Follow quality assurance procedures to prevent mistakes. Follow appropriate administration techniques.
