Good point Miss_Dee. But perhaps they want to make sure that the cows, which are going to the market, arent contaminated. OR, maybe they want to make sure the cows ARE contaminated. They might want beef tainted since we all eat beef. A lot of people eat beef regularly, I find it strange that most 'experts' claim that red beef is not good for us, swine isnt much better, it is white meat and fish that has the most nutritional value. So perhaps beef is being modified on purpose. I think cattle mutilations are part of some kind of real government conspiracy. I'll try to come up with some theories based on research of health risks associated with the consumption of beef.
