The USDA’s Foreign Agriculture Service (FAS) has compiled a database of international maximum residue levels (MRLs) for products currently approved for use in the U.S.
This database allows the user to obtain a pharmaceutical or pesticide MRL in a specific country for a variety of commodities. The database will notify the user if the MRL of the importing country is more restrictive than that of the U.S. Unfortunately, the database does not provide a recommended withdrawal period to ensure compliance with the importing country’s MRL. It is left up to the veterinarian to establish an appropriate withdrawal period.
The National Pork Board maintains a similar database for Japanese MRLs which contains recommended withdrawal periods provided by the drug manufacturer to avoid a violative residue in products exported to Japan.
