Make Mad Cow dead meat: In Europe and Japan, every adult cow is tested for Mad Cow Disease at slaughter--before it enters the food chain. By contrast, the US sporadically tests for the disease, checking only 20,526 cows prior to slaughter last year, out of 35 million prepared for your dinner table (the EU tested 10 million last year alone). Sign the Organic Consumers Association petition demanding that the U.S. government adopt and enforce mandatory testing for all cattle brought to slaughter, before they enter the food supply, and that they ban the feeding of blood, manure, and slaughterhouse waste to animals.
