The FDA announced that a drug fed to chickens will no longer be sold in the U.S. Pfizer subsidiary, Alpharma will discontinue sales of 3-Nitro. Chickens are fed this drug to increase their appetites. The FDA found that chickens fed arsenic had traces of the drug in their meat, primarily their liver. Pfizer will stop selling the drug in 30 days, after animal producers have had time to find new medications. 3-Nitro, a.k.a. roxarsone is the most common arsenic based animal drug, but similar drugs have been approved for poultry and pig feed.
