This feels appropriate, considering the recent research about all the creepy chemicals our chickens are eating: Maryland is just about to become the first state in the U.S. to ban arsenic in chicken feed.
You may be wondering why anyone would feed a chicken arsenic in the first place. (Unless, say, the chicken was in an Agatha Christie novel, and had just come into a large inheritance.) But while arsenic is certainly a poison — and has been shown to contribute to diabetes and heart disease — it’s also used to fight parasites in animals. The arsenic-containing drug roxarsone, manufactured by Pfizer, also promotes blood vessel growth, which can make meat appear pinker and plumper. Purdue and McDonald’s both refuse to feed it to their chickens. Canada and the European Union prohibit it as well.
