Nice of heavenfall to help you out there. But I'm sorry to say that your premise is flawed when it comes to this game. For one, in the lore, it does not say that the animal, which they got the salted pork, does not come from an animal that did not chew its own cud or a split hoof. For example the salted pork doesn't look like pork to me, but more of a chicken.
I am also pretty sure that any potion or brews in the game are not Kosher. You will have a lot of editing to do to ensure that everything in this game is Kosher.
Your other argument about the sailors who died from scurvy, has nothing to do with the fact that they consumed pork. It was the lack of vitamin C in their diet, which at sea they can only bring so much fruit before they ran out. Hence the reason for scurvy. There are also other sailors who died at sea and never consumed pork and got scurvy, because they couldn't get the fruit that they required. Look at the sailors that ate fish.
