One of the US’ largest poultry producers, Tyson Foods Inc., has announced that it plans to ban the use of human antibiotics in its chicken flocks by September 2017.

“Antibiotic resistant infections are a global health concern,” said Donnie Smith, president and CEO of Tyson Foods.

“We’re confident our meat and poultry products are safe, but want to do our part to responsibly reduce human antibiotics on the farm so these medicines can continue working when they’re needed to treat illness.”

Tyson Foods has already stopped using all antibiotics in its 35 broiler hatcheries, requires a veterinary prescription for antibiotics used on broiler farms and has reduced human antibiotics used to treat broiler chickens by more than 80% since 2011.

“Given the progress we’ve already made reducing antibiotics in our broilers, we believe it’s realistic to shoot for zero by the end of our 2017 fiscal year. But we won’t jeopardize animal well-being just to get there.

“We’ll use the best available treatments to keep our chickens healthy, under veterinary supervision,” Smith said.

Tyson Foods is also forming working groups with independent farmers and others in the company’s beef, pork and turkey supply chains to discuss ways to reduce the use of human antibiotics on cattle, hog and turkey farms. Those groups will begin meeting this summer.

Tyson Foods’ international business, it says, is committed to taking similar measures on antibiotic use in its global chicken operations but has not set a timeframe.

“One of our core values is to serve as responsible stewards of animals – we will not let sick animals suffer,” Smith said.

“We believe it’s our responsibility to help drive action towards sustainable solutions to this challenge by working with our chicken, turkey, beef and pork supply chains.”

The Arkansas-based company is a key chicken supplier to McDonald’s.
