The US Food and Drug Administration (FDA) has moved to protect the effectiveness of cephalosporins in humans by issuing an order to prohibit certain uses of the drugs in major food-producing animal species. The order becomes effective on April 5.
The FDA's order bans “extralabel,” or unapproved, uses of the cephalosporin class of antimicrobial drugs in cattle, swine, chickens, and turkeys. Prohibited uses include administering the drugs for disease prevention and using unapproved dose levels, frequencies, durations, or routes of administration.
