Research has shown the proper use of antibiotics can keep food animals healthy and reduce the potential for harmful bacterial contamination of finished meat products. Medically, important antibiotics added to feed or water are only used in animal food when it is necessary to treat, control, or prevent disease and illness, and exclusively under the supervision and prescription of a licensed veterinarian.
