The Food Safety and Inspection Service has a new system for testing meat carcasses for violative new animal drug residues and disposing of affected tissues. The measure will take affect on June 7.
In Aug. 2001, FSIS announced the agency's intention to make its procedures consistent with those of the Food and Drug Administration with respect to applying FDA's target tissue/marker residue policy.
Under the new system, if FDA has established a marker residue tolerance in a specific target tissue for a new animal drug but has not established a tolerance for muscle tissue, FSIS will only test the target tissue identified in FDA's regulations.
If the target tissue residue exceeds FDA's tolerance, FSIS will consider the entire carcass to be adulterated, and will condemn it.
However, if FDA has established an animal drug residue tolerance for muscle tissue and an official analytical method for detecting muscle residues, FSIS will test the muscle tissue using FDA's method to determine whether the concentration of residue is at or below acceptable levels. If the residue concentration in the muscle is at or below FDA's tolerance, FSIS will release the muscle tissue and allow its use for human consumption.
For new animal drugs for which tolerances are established for all edible tissues, but for which a target tissue isn’t identified, the agency will continue to collect multiple edible tissue samples and allow those with residue levels at or below the established tolerances to be used for human food.
