Today, Dr. Grandin is a best-selling author, and her Animal Welfare Audit is the standard in the industry. Half of the cattle in the United States and Canada are now handled by equipment Grandin designed. Some of the nation’s largest beef servers and suppliers— McDonald’s, Wendy’s, Burger King, Cargill, Tyson— pass the points of her audit: at least 95 percent of animals stunned on the first shot (usually with a captive-bolt gun that shoots a steel bolt into the head). No more than 1 percent falling. No more than 3 percent mooing. No more than 25 percent being hit with an electric prod. At this point, she says, “You can take someone right to the stunner line at one of the biggest slaughterhouses in the world,” and they’ll approve of what they see.
This Is What Humane Slaughter Looks Like. Is It Good Enough?
