To my understanding (someone please correct me if I'm wrong) transmissions of prions disease is primarily through two methods, eating of brain matter, something most never do, even eating animals brain matter, or undercooked flesh (and/or bodily fluids - like blood, which ties into undercooked flesh).

So it should be safe in theory, as long as we properly cook the meat and don't eat the brain. Since we do the same for all of the meat we ingest, it should be fine....

Not that I'm going to go advocating for anyone eating human meat. I'm just saying, to my understanding, if we follow standard handling and cooking, we shouldn't really have any risk factors for prions disease. Personally, I'll stick to beef, chicken, turkey, lamb and pork. If it's all the same to everyone else.... And obviously some delicious veggies and fruits.

Related: prions disease can result from other sources, such as genetics or "sporadically"... According to the wiki article on it, but I'm strictly speaking about transmission of the disease.
