BSE to CJD?

Creutzfeld-Jacob disease (CJD) in humans, BSE in cows and scrapie in sheep are related diseases. The BSE epidemic probably resulted from cattle eating feed containing meat prepared from infected animals. Since 1989, adult cattle tissues (such as brain and spinal cord) that may be infected with BSE have been banned from human food in the UK. But because of the long incubation period of these diseases (possibly as much as 10 to 20 years), some people might have been infected before the ban was introduced.

Since 1989, UK abattoirs have been required to remove the brain and spinal cord of cattle.
