ask doctor the reason of something, he will tell you a disease.
Tbh honest if diseases were such a cultural hinderance, there would be so many traditions that would never be. And the causations of raw pig meat and some parasitic diseases is something relatively recent, compared to the biblical times when this tradition has appeared.
And dont come with darwinist stuff, telling me only the people who refused to eat pig survived.
Not to mention other diseases from other raw meats that people keep forgetting about.
I still thinking it was a resource influenced decision, feeding a pig when you could fed a person with the same food was wrong, and goats, cows and chickens could actually thrive on foods that the human being could not.
