Spencer, IA: Oct. 31, 2013 – U.S. drugmaker Merck & Co plans to resume sales of the controversial Zilmax animal feed additive in the United States and Canada after it completes an audit of how the product is used.
Merck halted sales of the muscle-building drug in August after Tyson Foods said it would stop accepting Zilmax-fed beef after observing some cattle having difficulty walking or moving.
A spokeswoman for Merck’s Animal Health Unit said this week that while “it is too early to speculate on when we will resume sales for Zilmax in the U.S. and Canada,” Merck is pushing forward with its quality control program to ensure the drug is being properly used.
It was the first time the company has said it intends to bring the popular product back to the market.
Merck says it continues to stand behind the safety of its product.
