NOTE:
The U.S. Food and Drug Administration (FDA) issued a final rule on July 3, 2008 prohibiting the extra-label use of cephalosporins (including ceftiofur in swine) in food-producing animals. The agency is issuing this order based on evidence that extra-label use of these drugs in food-producing animals will likely cause an adverse event in humans and, as such, presents a risk to the public health. Public comment regarding the rule will be accepted until September 2, 2008 and the rule will go into effect on October 1, 2008.
