Isn't the ban on pig products thought to have been based on it being a disease vector? Considering that this is no longer relevant with modern sanitation and medicine it would seem they're using it as a checklist rather than applying any sort of logic.
The disease vector is more modern speculation/post-hoc rationalization for the rules. It's not really anywhere in the text itself aside from references to the animals being 'unclean.' It's likely that a variety of factors went into the rules, not least of which were probably just wanting to maintain some social and cultural separation from the communities around them.
