What Is Mad Cow Disease and Variant Creutzfeldt-Jakob Disease? Mad cow disease is an infectious disease caused by prions that affect the brains of cattle. The actual name of the disease is bovine spongiform encephalopathy (BSE), a name that refers to the changes seen in brain tissue of affected cows.
The leading theory is that the disease is caused by infectious proteins called prions (say PREE-ons). In affected cows, these proteins are found in the brain, spinal cord, and small intestine. There is no proof that prions are found in muscle meat (such as steak) or in milk.here is no evidence that people can get mad cow disease or vCJD from eating muscle meat-which is used for ground beef, roasts, and steaks-or from consuming milk or milk products. People with vCJD cannot spread it to others through casual contact.
