A warning letter was sent to Dr. Douglas A. Tuthill, Noah's Ark Animal Hospital, Goshen, NY, for prescribing and dispensing gentamicin sulfate for the treatment of cows that were later offered for sale for human food with illegal residues of gentamicin. There is no permitted level for residues of gentamicin in edible tissue of cattle. Veterinarians who prescribe drugs for extra-label use in the treatment of disease conditions in food-producing animals assume added responsibility. The warning letter said that veterinarians who prescribe drugs for these types of uses must establish a substantially extended withholding period supported by appropriate scientific information. It also said that veterinarians must assure the identity of a treated animal is carefully maintained, and they must take appropriate measures to assure that assigned timeframes for withdrawal are met and no illegal residues occur.

A warning letter was sent to Dr. Howard F. Terrill, Manchester Veterinary Clinic and Supply, P.C., North Manchester, IN, for prescribing veterinary drugs for veal farms in Pennsylvania without a valid veterinarian/client/patient relationship. The warning letter stated that Dr. Terrill was selling drugs for extra-label use which do not meet the conditions of the Animal Medicinal Drug Use Clarification Act for legal extra-label use.
