The people who raise cattle, of course.
At one time, cattle were fed the unwanted parts of ground up sheep. Some of those cows became infected with mad cow disease. Mad cow disease spread to humans. Cattle were also fed parts of ground up cow parts, cows eating ground up cattle were infected with that disease. The breakthrough came in New Guinea. There, women and children would eat the brains of dead people. Men would not. Women and children would catch a disease similar to mad cow disease. Men would not. That made it obvious that the disease came from something common to women and children and not to men. Since they behaved the same as nearby groups except for eating the brains of dead people, that had to be the difference. The only difference in the brains of the dead people with mad cow disease and those without mad cow disease was the prions. This was then tested in England where mad cow disease was common. The only difference between cows with mad cow disease and those without mad cow disease were the same prions. The people with mad cow disease had the same prions in their brains.
