Bovine spongiform encephalopathy (BSE), commonly known as mad-cow disease (MCD) is a fatal neurodegenerative disease in cattle that causes a spongy degeneration in the brain and spinal cord. BSE was first recognized in Great Britain (GB) in 1986 The infectious agent in BSE is believed to be a specific type of misfolded protein called a prion. The emergence of a new form of the human prion disorder Creutzfeldt-Jakob disease (CJD), termed variant CJD (vCJD) in the UK has also been shown by transmission and molecular studies to be causally linked to the BSE agent. Consequently, in 1996 the consumption of the meat of cattle with more then 30 month age was prohibited. In 2001, WHO, FAO and OIE jointly convened a Technical Consultation on BSE: Public Health, Animal Health and Trade. The following tips are some of decisions of mentioned conference. _ Countries should not become complacent about their risk from BSE. Because, the extremely low initial incidence and limited clustering of BSE cases, protracted latency and non-specific nature of the early clinical signs of Bovine Spongiform Encephalopathy tend to mask the severity of the problem. _ All countries are urged to evaluate their potential exposure through systematic assessment of trade data and possible risk factors. Accordingly in present study different aspects of BSE, consisted of: survey on present situation of BSE in Iran and globe; analysis of troubles and limitations related to BSE; review on the results of previous researches were investigated. Finally, some main projects correlated to BSE, which are needed to be performed, was determined and introduced.
