Mad Cow Disease: Causes, Symptoms, Prevention, and Sources
Mad Cow Disease, also known as BSE, is a fatal and slowly progressive neurological disease found in adult cows. It is caused by an infectious protein called a prion, and feeding cows contaminated feed can contribute to its spread. Symptoms include neurological problems, weakness, and weight loss. Prevention involves banning the feeding of cow parts/blood and chicken litter. Contracting the human form of the disease is very rare. Learn more about this disease from reputable sources provided.
