Bovine Spongiform Encephalopathy (BSE)

Bovine Spongiform Encephalopathy (BSE), commonly known as “mad cow disease,” is a chronic, degenerative neurological disorder affecting the central nervous system of cattle. BSE belongs to a family of diseases known as the transmissible spongiform encephalopathies (TSEs). The disease was first diagnosed in 1986 in Great Britain. The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) is enforcing import restrictions and is conducting surveillance for BSE to ensure that this serious disease does not become established in the United States.
