If you remember back in the 1980s one of the main reasons for Mad Cow Disease was because part of their daily supplement included ground-up downer cattle, which in humans became Creutzfeldt-Jakob disease (CJD)
Not just cattle fodder, but a lot of that feed also contained ground up sheep who had been slaughtered because they were suffering from the sheep version of 'mad cow disease' - called scrapie. Scrapie has been a known disease of sheep for many, many decades.
This is all very similar to the Wuhan bat soap scandal not too long ago. I sure hope feeding and eating gets better from now on!
Basically, Yes. The same agent for infectious disease, the prion, which killed the cows, was also responsible for killing hundreds of New Guinea tribesmen who practiced cannibalism. They ate the brains of their dead enemies, and died from a disease called Kuru
I know, I remember writing a report about mad cows disease at the time, and it's connection with scrapie's and other prion based diseases.
