## Abstract

The Food and Drug Administration (FDA, the Agency) is issuing an order prohibiting certain extralabel uses of cephalosporin antimicrobial drugs in certain food-producing animals. We are issuing this order based on evidence that certain extralabel uses of these drugs in these animals will likely cause an adverse event in humans and, therefore, present a risk to the public health.
