FDA WARNING_LETTER - Rupert Veterinary Clinic - May 29, 2015

Dr. Robert Ceglowski, DVM, caused the new animal drug sulfadimethoxine (ANADA (b)(4)) to be unsafe and adulterated under sections 512(a)(1) and 501(a)(5) of the FD&C Act, respectively, by failing to comply with 21 CFR Part 530, Extralabel Drug Use in Animals.

Specifically, Dr. Ceglowski prescribed sulfadimethoxine to calves for pneumonia at (b)(4) without ensuring the drug's extralabel use would not result in violative drug residues. This violated 21 CFR 530.20(a)(2)(iv), as a bob veal calf from (b)(4) was later found to contain illegal residues after slaughter.

Furthermore, adding sulfadimethoxine to wasted milk for calves caused the animal feed to be unsafe and adulterated under sections 512(a)(2) and 501(a)(6) of the FD&C Act, respectively. This constituted extralabel use of a medicated feed, which is prohibited by 21 CFR 530.11(b).
