TURKEY
Harmful Ingredient: Arsenic. You may know arsenic as a toxic chemical, but it’s also handy at staving off parasitic infections in poultry. As recently as early 2011, a drug called Roxarsone—which was later found to contain traces of inorganic arsenic—was still being used in chicken feed for this reason, and because it made chicken meat appear pinker and fresher. Since then, the National Chicken Council has said that it is no longer using arsenic-based drugs.
