Antibiotics, that may be found in milk as a result of mastitis therapy or by their direct addition, could control and even cause a decrease in the numbers of bacteria in raw milk. This could result in the acceptance of poor quality milk as an acceptable high grade milk if judged solely by bacteriological standards. Public health officials, veterinarians, milk producers and dealers, and pharmaceutical manufacturers all should be made aware of this serious problem.
