The Denver lab will test for Chloramphenicol, Tetracyclines, Sulfonamides, Beta Lactams, Novobiocin, Ivermectin and Clorsulon.
States are ask to obtain samples from farm tankers for testing prior to unloading.
If a state is unable to collect samples, FDA will assist the state as resources allow. FDA Regional Milk Specialists will notify state regulatory and rating agencies. States will be notified of all their sample test results run at the Denver laboratory. If the state requests assistance in that investigation, FDA is prepared to assist. In addition, FDA will provide assistance to state agencies when it is necessary to preserve a chain of custody of evidence such as investigations of mobile peddlers, mail order drugs, mislabeled drugs from out of state manufacturers, re-packers, or distributors.
