The U.S. Food and Drug Administration’s Center for Veterinary Medicine (CVM) took the first step toward rescinding its approval of the use of carbadox to treat swine because the drug may leave trace amounts of a carcinogenic residue.
CVM’s action comes after the center recently reexamined the safety profile of the drug and conducted a preliminary risk characterization that indicated there could be potential risk to human health from ingesting pork, especially pork liver, derived from carbadox-treated pigs.
