•White-tailed deer (Odocoileus virginianus) were intramuscularly injected with florfenicol, ceftiofur, tulathromycin, oxytetracycline, and moxidectin.•At day 11, 21, and 31 post injection, only tulathromycin was detected at a level >0.01ppm in the deer liver and muscle samples tested.•Oxytetracycline was only detected in liver at day 11 post injection; no other drugs were detected in either muscle or liver at these time points. Tissue residues were determined after intramuscular injection of florfenicol, ceftiofur, tulathromycin, oxytetracycline, and moxidectin in 102 white-tailed deer (Odocoileus virginianus). At day 11, 21, and 31 post injection, only tulathromycin was detected at a level >0.01ppm in the deer liver and muscle samples tested. Oxytetracycline was only detected in liver at day 11 post injection; no other drugs were detected in either muscle or liver at these time points.
