Abstract

Responses of three on-site slaughterhouse screening tests, along with the FSIS - USDA Post-Screening Multiple Bioassay, are described. On-site tests include the CAST, STOP and FAST.

Kidney, liver and muscle were obtained from lactating dairy cattle after the last of five intramuscular injections of ceftiofur sodium* administered at 24-hour intervals at a dose of 2.2 mg or 1.1 ceftiofur equivalents (CE) per kg of bodyweight (0.5-1.0 mg/lb). Animals were slaughtered at 12 hours or five or 10 days.
