Read the passage from When Birds Get Flu and Cows Go Mad! by John DiConsiglio.

Early that morning, a tissue sample from a cow in Washington State had tested positive for bovine spongiform encephalopathy (BSE)—also known as mad cow disease. That’s a rare brain disorder that kills both animals and humans. In Europe, hundreds of thousands of cows have caught the disease. And 150 humans have died from it.
