Bovine spongiform encephalopathy--a new disease transmissable to humans?
Current concerns about the cattle disease bovine spongiform encephalopathy do not appear to take cognisance of the parallel with scrapie, the similar/identical disease of sheep/goats. This has existed for 200 years, and clearly involved a longstanding consumption of meat/offal from affected animals, but apparently without consequential human disease. A summary is given of the characteristics of the human and animal spongiform encephalopathy diseases and their causative agents. The conclusion of the official Southwood Report that the bovine disease is caused by the inclusion of sheep scrapie material in cattle fodder is critically discussed: an alternative mechanism is proposed for its emergence.
