AASV Recommendations to Meet MRL Requirements of U.S. Pork
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 AASV product withdrawal database contains only products for which the manufacturer has supplied specific MRL withdrawal information. Products without specific MRL withdrawal information are not listed.
- 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 than its proprietary equivalent. Follow the specific product withdrawal recommendation.
- Follow the recommended product withdrawal to meet the 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
