Bovine spongiform encephalopathy

Bovine spongiform encephalopathy (BSE) is characterized by behavioural changes, locomotory disturbaances and loss of condition. The course of the disease is about 1-3 months terminating in death in some animals, but many are slaughtered because of unmanageable behaviour or trauma due to failling. Affected cattle were first identified in the United Kingdom in 1986, as a result of feeding contaminated ruminant protein and affected nearly 200 000 cattle. Since then BSE has been reported in several other countries. Variant Creutzfeldt-Jacob disease in humans most likely results from the consumption of beef products contaminated by central nervous system tissue.
