(WASHINGTON) -- The drugmaker Pfizer has stopped selling 3-Nitro, a widely used animal drug, after arsenic was found at elevated levels in livers of chickens treated with the product.
The FDA says it is concerned about "a very low but completely avoidable exposure to a carcinogen" in the drug, which is used "to help control coccidiosis, a parasitic disease that affects the intestinal tracts of animals," according to the Food and Drug Administration (FDA).
The drug "has also been used for weight gain, feed efficiency and improved pigmentation,” the FDA said.
"FDA officials stress that the levels of inorganic arsenic detected were very low and that continuing to eat chicken as 3-Nitro is suspended from the market does not pose a health risk," the agency said.
