The U.S. FDA has announced that Pfizer will stop the sale of the animal drug 3-Nitro. The drug is used in chicken feed, but an agency analysis detected inorganic arsenic in the livers of chickens treated with the drug.
3-Nitro is used to help control coccidiosis, a parasitic disease that affects the intestinal tracts of animals, and also so that the chickens will gain more weight.
The Wall Street Journal reports:
"The agency said it recently conducted a study of 100 broiler chickens that detected inorganic arsenic at higher levels in the livers of chickens treated with 3-Nitro compared with untreated chickens ... Pfizer said sale of 3-Nitro would be stopped by early July in order to allow animal producers to transition to other treatments."
