FDA to revoke pig drug approval over human cancer risk concern

The U.S. Food and Drug Administration on Friday moved to revoke approval of a drug used to treat certain conditions in pigs because it could leave a cancerous residue that may affect human health.

The drug, carbadox, is made by Teaneck, New Jersey-based Phibro Animal Health and is used to control swine dysentery and bacterial enteritis, the agency said. It has also been used to promote weight gain in pigs.

"Potential cancer risks are based on an assumed lifetime of consuming pork liver or other pork products containing carbadox residues," the agency said in a statement, adding that it is not recommending that people change their food choices while it works to remove the drug from the market.

"Pork is a good source of protein," the agency said. "However, protein can also be found in other meat, poultry, seafood, beans and peas, eggs, processed soy products, nuts and seeds."

Pork liver is used to make liverwurst, hot dogs, lunch meat and some types of sausage, the agency said.

Officials for Phibro, which generates annual sales of more than $650 million and employs more than 1,100 people worldwide, according to its website, were not immediately available for comment.

If it does so, the FDA's commissioner, Dr. Robert Califf, will decide whether a hearing is justified. If the company does not request a hearing, the agency can withdraw approvals for carbadox and it would no longer be legal in the United States.[/color][/size][size=10px][/size][/size][size=1.6em][/color][color=rgb(34, 34, 34)]The FDA's actions follow a preliminary risk assessment conducted from 2012 to 2014 which found that the lifetime cancer risk from consuming pork liver containing carbadox residue is higher than allowed under the FDA's framework for regulating carcinogenic animal drugs.[/color][/size][size=10px]

Kwami love Pork Liverwurst 

I man prefer ramgoat liver !

That title alone is enough to really make you shake your head at the pharma industry, but I guess I cannot say that I am really surprised at this point.  I am not really sure what to make of the FDA and the process for drug approval anymore, because there seems to be bad news every other week.  I will be curious to see where this one goes.
