Pigs eat anything. Well, maybe not rocks. I'm not sure about that though, they might still try.

If you want to see what happens when pigs that eat near human faeces are eaten by us: https://www.cnn.com/2019/03/28/health/brain-parasites-case-s...

The CDC specifically say that you don’t get cysticerosis from eating pork, though the correlation with pigs eating human faeces is mentioned. As always, it seems that washing your hands is important.

I have seen first hand that they do, not that I wish I hadn't.

Pigs eat everything, including humans.

Pigs even eat pork. There is currently a problem with swine fever infected pork being reintroduced as feed in places like china. It is one of several vectors for the lethal (to pigs) disease.

Well to be fair, if you were served some nameless meat, would you be confident in your ability to identify human and/ or not like the taste of it?

Chickens will eat egg shells, and it's apparently a good source of minerals for them. You do have to scrunch them up, or else, from what I understand, they start associating egg shells with food, and start pecking their own eggs.

Its also good to bake them for a bit. It helps with the 'scrunching' and nutrient availability (so I've been told).
