Cannibalism

[Pyrrho]

... Now, we can't argue that it's not smart because of disease because they bury those and besides, if you cook meat thoroughly enough don't you pretty much get rid of anything that could be alive? ...

CJD (Creutzfeldt–Jakob disease) and similar diseases are caused by prions. Prions are proteins, not life forms. You cannot destroy them from even using routine surgical sterilization processes. In other words, ordinary extreme heat is not enough. So, cooking it thoroughly isn't going to matter at all for this. If you get it, it will kill you unless you die from something else first. If you die from this, after you are dead, if they do an autopsy on you, your brain will look a bit like a sponge, with lots of holes. You do not want this, and to avoid it, you should avoid eating anyone infected with this. There is no preparation of the dead body that will make it safe to eat.

If someone has this, in the early stages, there are no symptoms, so you ordinarily will not know if someone is infected or not, if they die of something else first.

You can do an online search for these things to verify everything I have stated in this post.

Now, none of this is a moral reason to not eat people. This is a practical one.

I would recommend avoiding eating other primates as well. Basically, the more something is like you, the more likely it is that you might get some nasty disease from it. Vegans are probably the safest as far as contracting diseases from food is concerned, though since even vegetables are sometimes contaminated with animal products, there are no guarantees of safety.
