What is in your chicken? A new study found that chickens were eating feed containing a banned antibiotic and the active ingredients for pain relievers, antihistamines, and antidepressants. There’s been growing concern over the use antibiotics in animal farming. Close to three-fourths of all antibiotics are used for farm animals and this overuse, according to public health experts, is breeding antibiotic resistant bacteria that are a serious threat to human health. The Food and Drug Administration recently asked the livestock industry, drug companies and veterinarians to voluntarily limit their use of antibiotics in agriculture. But many people say this doesn’t go far enough. We’ll look at antibiotics in farming, the recent “pink slime” controversy and other issues around the way we produce our food with MICHAEL POLLAN, author of “Food Rules” and “The Omnivore’s Dilemma.” We’ll also talk with KEEVE NACHMAN, Director for Farming for the Future at Johns Hopkins Center for a Livable Future and one of the authors of the recent chicken feed additive paper.
