In 1985, a mystery disease now known as Bovine Spongiform Encephalopathy [BSE or mad cow disease] first appeared in a dairy cow from Kent, England. Within the space of three years, the annual number of BSE-infected cattle in Britain rose to 731. By 1989, 400 new cases appeared each week. By 1992, 100 new cases appeared daily. BSE subsequently spread to fifteen other mainland European countries, leading to the slaughter of five million cattle over the past sixteen years.
