According to Jewish Myths and Legends, (one version), the Pig was created by God to clear up, eat, all the droppings from the other animals and humans, and left over food on the Ark. (the Pig is omnivorous).
In reality, there were no Kosher laws prior to the book of Leviticus, so its possible that until then, jews ate Pork.
There's some evidence also, in the New Testament, that Jewish businessmen kept pigs, although whether for eating or selling, it doesn't say.
This doesn't actuallyanswer your question, but i'll be watching for other replies, I might learn something.
