Arsenic_in_Chicken What Was Arsenic Doing in Our Chicken, Anyway? - It might seem like cause for cheer that the U.S. Food and Drug Administration has ordered (September 2013) the withdrawal of most drugs containing arsenic fed to chickens, turkeys and hogs. - one of the four drugs banned will stay on the market and continue to be fed to turkeys - Why arsenic was even in animal feed in the first place is fairly shocking, though perhaps not so much given how industrial farms raise much of the food we eat. Since the 1940s, farmers have fed arsenic to animals as a way to promote growth and weight gain with less feed. - Just as troubling as evidence that trace arsenic might be in the meat we eat is what happens to the toxin once it is passed through as animal waste. Some of the waste is used as fertilizer, or isn't properly disposed of, leading to arsenic in soil, water and crops. - Even though the producer now has agreed to pull this toxic  feed chemical off the shelves in the United States, it says it won’t necessarily remove it from feed  products  in other countries unless it is forced by regulators to do so.
