Inhibitors - And the Livestock Medicines Education Program

Last Updated: March 11, 2013

Several tests are used to detect the presence of inhibitors in milk. Inhibitors in milk pose a serious human health hazard and should be avoided. First time offenders cause over 95 per cent of inhibitor violations. Proper treatment protocols, identification of treated animals and accurate record keeping will help to prevent milk from treated cows entering the bulk tank. Adherence to withdrawal times, on-label administration, careful use of medicated feeds and topical treatments as well as inhibitor testing of purchased animals can minimize accidental introduction of inhibitors into milk.
