## Abstract

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect the revocation of tolerances for residues of various substances in food because approval has been withdrawn for the underlying food additive petitions (FAPs) or new animal drug applications (NADAs). This action is being taken to improve the accuracy of the regulations.
