If you saw “Arsenic in Our Chicken?,” Nick Kristof’s much-read New York Times column from earlier this month, you’ve heard about the widespread use of some unexpected additives in chicken farming.
Studies released this year detected caffeine, acetaminophen (the active ingredient in Tylenol), fluoxetine (the active ingredient in Prozac), various antibiotics, arsenic, and more in feather meal, a substance made from ground poultry feathers and used in animal feed. The findings were the results of studies by the Johns Hopkins Center for a Livable Future and Arizona State University.

Last year, the Food and Drug Administration (FDA) tested 100 chickens that had been raised on a popular arsenic-based additive called Roxarsone, and found that half the chickens had inorganic arsenic in their livers — a known carcinogen that can cause cancer even at the low levels found naturally in our environment.
