Following the lead of fast-food giant McDonald's ($MCD), Tyson Foods ($TSN) said it would eliminate the use of human antibiotics in its chicken flocks by September 2017. It's an ambitious timeline, but one that will help it meet a deadline set by McDonald's, which will be eliminating antibiotics-raised chicken items from its U.S. restaurants over the next two years. Tyson said it has already stopped using the drugs in its 35 broiler hatcheries and is now requiring prescriptions from veterinarians for antibiotics used on broiler farms. The moves come amid a renewed push by the FDA and federal legislators to combat the problem of antibiotics resistance in people. Article
