Somebody told me pork is the closest thing to human flesh. That´s why cannibals called sailers long pigs.

Also heard some firemen or anyone who have had the misfortune of getting the smell of burnt human flesh, cannot stand the smell of pork. It reminds them of it.

Also certain religions traditions of avoiding pig meat is simply due to in the hot climates where the religions orginated, keeping pork without refringeration was dangerous and many died of food poisioning.

It was a practical thing more than anything else.
