The United States Department of Agriculture (U.S.D.A.) explicitly allows diseased animals to be slaughtered and used for human food. It has taken a “don’t look, don’t find” approach when it comes to potential human health hazardous. Amazingly, the Agency has even gone to court to fight to prevent animals from being tested for disease! And they recently won a case to prevent a slaughterhouse from testing cows for mad cow disease. Why would the U.S.D.A. and other agribusinesses work so hard to prevent animals from being tested for disease? I think they’re afraid of what they’d find.
