“A new cattle drug called Zilmax is being widely used in the industrial feedlots where most of America’s beef comes from, but not because it produces a better sirloin. In fact, it has been shown to make steak less flavorful and juicy than beef from untreated cattle. Many feedlot owners, big meatpackers, and at least one prominent industry group resisted the drug, worrying that the beef industry would turn off consumers if it started churning out lower-quality steaks. So what accounts for the sudden popularity of Zilmax? Zilmax is a highly effective growth drug, and it makes cattle swell up with muscle in the final weeks of their lives. And despite concerns within the industry, the economics of modern beef production have made the rise of Zilmax all but inevitable.” w/ photos
