An estimated 400,000 cattle infected with BSE entered the human food chain in the 1980s. [citation needed] Although the BSE epizootic was eventually brought under control by culling all suspect cattle populations, people are still being diagnosed with vCJD each year (though the number of new cases currently has dropped to fewer than five per ...
BSE is a degenerative infection of the central nervous system in cattle. It is a fatal disease, similar to scrapie in sheep and goats, caused by a prion.A major epizootic affected the UK, and to a lesser extent a number of other countries, between 1986 and the 2000s, infecting more than 190,000 animals, not counting those that remained undiagnosed.

Then human consumption of these infected cattle caused an outbreak of the human form CJD. There was a dramatic decline in BSE when feeding bans were put in place.

By November 1997, about 1,772,000 cows had been slaughtered under the scheme, with compensation of 1 ecu per kg, reduced to .9 ecu in October 1996, and later to ...

The veterinarian determined that the cow was suffering from complications of calving. Samples of tissue were taken for further testing for BSE.
