TESTING FOR MAD COW DISEASE TO DECREASE

MAD COW

Right on the heels of confirmation of the third case of mad cow disease in the US. The FDA announces that its going to decrease the number of test they perform. What I don't understand is that the FDA and the USDA had both stated that the incidence of mad cow disease would almost completely if cattle farmers would stop feeding their cattle animal by-products. Cow are herbivores, they don't eat animal by-product by nature so why feed it to them? Its these by-products that are the carriers for Mad Cow Disease.
