Federal Register Final rule: FDA is amending the animal drug regulations to reflect the limitations to conditions of use for products approved under 22 NADAs and five ANADAs. A label statement warning against the use of these products in calves to be processed for veal was not codified at the time supplemental NADAs or ANADAs were approved. FDA is also amending the animal drug regulations to reflect the approved preslaughter withdrawal periods and milk withholding period in cattle following use of penicillin G procaine aqueous suspension.
