CME rules on Zilmax ban
24/09/2013
"We are letting the market know these Zilmax cattle no longer are merchantable in our view from a contract specification perspective because they will not be accepted by a majority of our approved slaughterhouses," said CME managing director of Commodity Research and Product Development, David Lehman.
The exchange made its decision after two major packers, Cargill and Tyson, discontinued purchases of cattle fed with the weight enhancer.
Its manufacturer Merck suspended Zilmax sales in Canada and the United States to conduct further research – although no official link to cattle illness has been announced.
