Glatt you really should read the articles you post. The cow was affected with ATYPICAL BSE a form that occurs spontaneously in cows and human beings but is not the type that can be infectious to animals or humans. It is not a zoonose.

"The USDA tests about 40,000 cows a year."

This cow was not a downer cow it was DEAD.
On any given day a dairy has three or four carcasses of cows that may have died from old age. Rendering companies, commonly known as "fat and bone collection," pick them up for processing into commercial products such as makeup, chicken feed and pet food.
