What importance did geography have in Jews not eating pork?

There is no geographical importance to Jews not eating pork. The prohibition against eating pork is a religious one, and it is found in the Torah, which is the sacred text of Judaism. The Torah states that "the pig is unclean to you" (Deuteronomy 14:8). There is no mention of geography in this verse, or anywhere else in the Torah, regarding the prohibition against eating pork.
