Administer all drugs properly and identify all treated animals. Maintain and use proper treatment records on all treated animals. Use drug residue screening tests. On-farm tests are powerful tools, telling farmers when it is safe to market milk and meat from treated animals. Dairy farmers are encouraged in their use, although it must be recognized that all tests have certain limitations and the observing of proper withdrawal times is imperative to avoid useless testing.
Different tests apply to different drugs.
It is important to know the sensitivity of the test relative to the maximum legal level of drug residue allowed. No one test will detect all drugs. Complete the milk and dairy beef residue prevention protocol annually, and review and refine its effectiveness with the veterinarian on your farm annually. Quality is a quest, not a destination. A farm plan of action is in the producers manual.
