    What is mad cow disease?

    • Mad cow disease is also known as bovine spongiform encephalopathy (BSE). 
    • It is a transmissible, slowly progressive, degenerative, and fatal disease which affects the central nervous system of adult cattle. The infectious agent that causes mad cow disease is an abnormal version of a protein normally found on cell surfaces called a prion.
    • When protein gets altered, it destroys the nervous system tissue- the brain and spinal cord.
