-Mad cow disease, formally known as Bovine Spongiform Encephalopathy (BSE). -Is a chronic degenerative disease that attacks the central nervous system of cattle. -Destroying brain tissue and eventually causing dementia and death. There is no known cure.
-In human beings it is known as the Creutzfeldt-Jakob syndrome -A rare neuro-degenerative disease that is a contagious form of spongiform encephalitis, -It is thought to be caused by a slow virus which is usually fatal and has no cure. -The main symptom is dementia (deterioration of brain function), -Other symptoms which can also occur include deteriorating muscles, tremors, and a variety of different neurological conditions. -Recent research has linked this disease with bovine spongiform encephalitis (BSE), more popularly known as "Mad Cow Disease," which is thought to be caused by a prion (an abnormally-configured protein).
WHAT TOOK PLACE BEFORE 1987 AND THE SUPPRISE OF BSE
-Scrapie, a disease that infected sheep, was thought of as a disease of sheep that did not infect humans, although its tissues were known to contain infection.
-When BSE arrived, it was immediately thought, because there were no other natural uses, to be derived from scrapie and for this to have been fed to cattle in the meal that they ate (to increase their milk production). -By the direction of the feeder guy, a change had taken place in the way that this was made in the early 1980s and this, taking place at a similar time to the original infection of the cattle, was felt to be the answer. It is now suggested that MAFF had been shown cattle with this disease before, and may have known about it in 1983, but did nothing.
-A small farm in Surrey reported more than one cow developing a strange neurological disease. -The cattle were killed, the brains removed, and the animals destroyed. When it was found that the cattle had a disease never reported before the farmer...
