there is lack of study which actually measures the amount of damage which can be caused by the toxin if humans were to consume them chronically

Probably every food consumed in excess can cause health issues to anyone.

Personally, I don't eat much pork, I prefer other types of food, but from time to time I do eat them.

is not for the sake of controlling its body temperature rather than expelling a small number of toxins.

I was aware of the fact these animals use mud to cool off their body but not that their sweat glands were for expelling toxins, and I agree with what you say about freezing, the safest way to eat meat is by freezing it first, whether it is pork or any other animal.
