Bovine spongiform encephalopathy (BSE) is a progressive, fatal, infectious neurologic disease of cattle that resembles scrapie of sheep and goats. It was first diagnosed in the UK in 1986. Approximately 200,000 cases of BSE have been diagnosed in cattle, almost all of which were in the UK. In 1992, at the peak of the UK outbreak, 37,280 cases were reported in a single year..
