The cause of BSE is unproven, although there is strong evidence that prions, which may be ineffective proteins, are the agent. Other hypotheses suggest that prions massage with an as to that extent undetected virus to cause the infection.

Recycled animal tissue, which had been routinely provide to British dairy cows as a protein supplement, was identified as the reference point of the infection. The European Commissions Scienti! fic Veterinary Committee and the world control body, the Fédération Internationale des Epizooties (FNE) believes that BSE was originally break from sheeps brains give with scrapie and that its spread was accidentally accelerate by the inlet of brain tissue taken from cows that had become infected with BSE.
