While I'm not a fan of "raw" meat of any kind. Though I do like it between rare and medium rare. You can get really sick from eating raw pork. Trichinosis while not usually a deadly condition is still pretty nasty. The thought of parasitic worms inside me gets my skin crawling.
I think that's why the jewish religion forbids it. It probably started out as a health issue and grew from there.
We have a friend that is a Pro Pork Rabbi.
He says that pork was outlawed for threse reasons.
1) it spoils and does not keep like Venison or beef. in the form of Jerkey or Biltong or what ever the middle eastern version of it is.
2) It is a dirty creature and will lay in it's own poop. In a land where washing was not a high priority having your dinner in poop was a bad thing because fresh water was at a premium.
3) they eat slop and the slop is what creates the worms.
4) in a desert there is not a lot of fuel to fully cook the pork and the worms become a problem
5) it takes the same amount of food to grow a domestic pig as it does a person. While a chicken, goat, sheep, or beef does not eat the same food supply as a person and far less grain is used to grow those animals. So you can either grow, for the same grain a pig or person. Also any part of the animal that has the syatic nerve in it is not Kosher. So most of the cow from the rib cage back is not kosher.
6) cow, sheep, and goat milk is used for dairy products and chickens lay eggs. But the Pigs are not milked anywhere in the world. So there are no secondary by products for the animal. Even the leather needs to be handled differently. High fat layers cause rot and not leather.
