Mad cow disease is caused by a prion. a prion is a malformed protein that is found in the brain tissue of infected cows, and exposure can be fatal. meat that comes in contact with infected tissue becomes contaminated with the prion. currently, there are no treatments for prion diseases because prions are hard to target and are too similar to normal proteins. to prevent the disease, scientists would most likely recommend that

The correct answer would be - brain tissues of infected should be separated from the meat so prion will not infect meat and cause disease.

Explanation:

Prions are the protein that leads to the other proteins to misformed or fold like them when getting in touch. These proteins can infect any normal protein through touched or contact. They cause disease in both humans and animals like a cow.

In human CJD is a common prion disease whereas in cows mad cow is normal. There is no known treatment for these diseases however can prevent it by separated animal meat with their brain tissue. Brain tissue mixing up or come in contact with meat can infect the meat with prions and result in disease to the person who eats it.

Thus, the correct answer is - brain tissues of infected should be separated from the meat so prion will not infect meat and cause disease.
