As there is currently a news story concerning Mad Cow Disease in Alabama, I am taking this opportunity to share this question.
Spongiform Encephalopathy is brain damage, caused by what an animal eats. Hexane is known to cause brain damage(Hexane MSDS), and Hexane is fed to cattle in large quantities (EPA found one-half to one pound per ton of Hexane in food meals, in averages of nine vegetable oil-processing plants.).

To find what does, and what does not cause the malady of Scrapie(aka Mad Cow Disease) one can look to the only two countries in the world known to be free of Scrapie and Mad Cow Disease; Australia and New Zealand.
Look at what they feed to their livestock. Australian and New Zealand livestock are normally fed only grass and grass hay. Their livestock are not fed grain supplements from the vegetable oil extraction industry. Given these straightforward associations, can Mad Cow Disease be explained in a more reasonable way?
