Merck & Co. announced recently that it will suspend sales of its weight adding drug, Zilmax. Why, after more than 2 decades of giving this drug to beef a few weeks before slaughter to improve weight gain up to 2%, has Merck suddenly grown a conscience? Apparently, Tyson Foods (bless their hearts!) has stopped buying beef that have been given this drug! Turns out, Mercks' motivation just might be financial, although we would like to believe their humanitarian spirit is guiding their decision making. Merck has announced that they will now conduct a study of the effects of Zilmax on beef. NOW they will conduct a study after more than 2 decades of use? Seems to me, the time for a study would have been before it was used on beef meant to be consumed by humans!
