Mad Cow Disease

Introduction

Mad Cow Disease is the common term for Bovine Spongiform Encepholopathy (BSE), a brain disorder in cattle which can be spread to other species, including humans. In humans, Mad Cow Disease is called Creutzfeldt-Jakob Disease. In sheep, it is called Scrapies.

Mad Cow Disease causes a spongy degeneration in the brain and spinal cord. The disease was first diagnosed in 1986 in the United Kingdom, where more than 179,000 cattle were infected and another 4.4 million were slaughtered during the eradication program. Since that time, it has been found in many European countries, and also in countries outside of Europe, including Japan, Canada, and the United States.
