BSE (commonly known as "mad cow disease") is a slowly progressive, incurable cattle disease of the central nervous system, first diagnosed in Britain in 1986.
Cattle's consumption of BSE-contaminated
ruminant proteins in animal feed has been cited as one possible means of
transmission.
Human consumption of brain and spinal cord-related tissue from BSE-infected
cattle is believed to be the source of variant Creutzfeldt-Jacob disease
in humans.
USDA banned the importation of live cattle from Great Britain in 1989, and imposed a partial ban on using ruminant protein in animal feed in 1997.
Ruminant - An animal with a stomach
that has four compartments, and a more complex digestive system than other
mammals.
Ruminants include cattle, sheep, goats, deer, bison, elk, and camels.
However, swine, dogs, and humans are examples of
non-ruminants.
