“Tyson Foods Inc declared it would no longer accept cattle that had been fed the most popular brand of the feed additive, called Zilmax, a powerful and fast-selling product from pharmaceutical company Merck & Co. The debate over Zilmax follows a similar dispute over ractopamine. China and Russia have banned the import of meat from ractopamine-fed animals, and the U.S.-based pork giant Smithfield Foods in May announced it will stop feeding ractopamine to half its pig herd, a move seen as an effort to recapture the lucrative China market. The FDA has deemed beta-agonists safe both for farm animals and for human health.”
