Mad Cow Disease

Also known as Bovine spongiform encephalopathy disease.

Mad Cow Disease

BSE is caused by prions, an indestructible brain-protein pathogen that warps normal proteins into new prions, making holes in the brain and turning it to sponge. BSE also wreaks havoc on the nervous system and major organs but apparently does not affect regular muscle tissue.

BSE (bovine spongiform encephalopathy) is a progressive neurological disorder of cattle that results from infection by an unusual transmissible agent called a prion. The normal prion protein changes into a pathogenic (harmful) form that then damages the central nervous system of cattle.

Transimition: cows and sheep that were old, sick, or otherwise unfit as human food were used as a cheap protein supplement in cattle feed. Thus, cows with BSE were consumed by other cows, which then became infected. Which then can be transmitted by direct consumption of the meat

Symptoms/ DiagnosisThe only way to confirm a diagnosis of BSE is by brain biopsy or autopsy. Symptoms include mental impairment . personality changes, including impaired memory, judgment, and thinking; and impaired vision. People with the disease also may experience insomnia, depression, or unusual sensations. As the illness progresses mental Impairment becomes severe

First reported in the United Kingdom in 1986 .As of May 2007, 160 people, all in the United Kingdom, had died after eating infected beef and developing a human version of the syndrome. It has been reported in many European countries
