Every tanker of milk is tested for beta lactam/cephalosporin antibiotics using FDA/NCIMS approved tests.

• A. True
• B. False
• C. Only if requested
• D. All shipments

Answer: (A)

Testing every tanker for antibiotic residues is a key safety step in the dairy supply. Beta-lactam antibiotics, including penicillins and cephalosporins, are commonly used in dairy cattle, and even small residues can cause allergic reactions or interfere with dairy processing like cheese fermentation. FDA/NCIMS-approved screening tests are used on each bulk milk load to detect these residues before the milk enters the system. If the screening is negative, the milk is released; if positive, confirmatory testing is done and the load may be diverted or rejected. This ensures withdrawal times are respected and that only milk free of detectable antibiotic residues reaches consumers.
