Maryland Law Banning Arsenic in Chicken Feed Takes Effect

"With the new year, Maryland becomes the first state to ban the use of additives containing arsenic in chicken feed, a practice already prohibited by Canada and the European Union."

"Last year, Pfizer suspended sales of its drug Roxarsone, an arsenic-based drug used to fight parasites in animals, after a Food and Drug Administration test showed trace amounts of the known carcinogen in the livers of chickens."
