Bovine Spongiform Encephalopathy Bovine spongiform encephalopathy (BSE) is a relatively new disease found primarily in cattle. This disease of the bovine breed was first seen in the United Kingdom in November 1986 by histopathological examination of affected brains (Kimberlin‚ 1993) . From the first discovery in 1986 to 1990 this disease developed into a large-scale epidemic in most of the United Kingdom‚ with very serious economic consequences (Moore‚ 1996).

Prion diseases‚ also known as transmissible spongiform encephalopathies (TSEs)‚ are neurodegenerative conditions that not only effect humans‚ but animals as well. Neurodegenerative have to do with damages that occur in neurons‚ which could even lead to neuron death. Neurons are what make up the nervous system; This includes the brain and spinal cord. Knowing this‚ the disease is very affective and could cause damage to the body as far as death. Prions are found in everyone’s bodies. There is a gene

“Mad”‚ thus the nickname‚ Mad Cow Disease. It was first identified in 1986 with possible cases in the 1970’s when Scrapie infected sheep were fed to cattle in the form of meat and bone meal. Scrapie was the first transmissible spongiform encephalopathy. The feed evolved to bovine meat and bone meal and was fed to young calves. The largest outbreak in the United Kingdom took place in 1995 with 14‚562 cases. In 2010‚ there were 11 reported cases. (Beef Checkoff‚
