It was not the research scientists that caused BSE. But rather the decision by the Government to allow Meat Renderers to self regulate. This led to sloppy practices, lower rendering temperatures and short cuts elsewhere. These allowed BSE to passed via treated waste products to cattle feed (when if proper regulation had been enforced I doubt this would have happened).We're in danger of playing with nature again. Dont forget that by feeding cattle with an unnatural (to them) foodstuff, it was food research scientists that inadvertently caused BSE.
