So not in favor of cannibalism, but kuru, the prison disease most commonly endemic to humans, is/was pretty much only found in the Fore, an indigenous population in Papua New Guinea. It broke out there because ritual funerary cannibalism enabled a prion likely from a random mutation to spread through the population. You won't get a prion disease if you don't consume the prion. The prion causing Kuru, like that of BSE, is mostly present in the nervous tissue of affected animals. This is one reason Kuru mostly affected women and children, who traditionally consumed the brains of the deceased.

Long story short, you can prolly eat capitalists' brains and the only thing you'll catch is the vile, parasitic brainstorms that cause them to seek infinite accumulation. But maybe don't eat an Englishman, they had a rough bout of BSE.
