Yes, the interest of this issue for me is that there's a long history of trying to "figure out" the pig prohibition—with layers of assumptions that don't, on examination, make any sense.
Many say that porn can have trichinosis and so that's why it's not eaten. But as Marvin Harris pointed out, pigs are immune to brucellosis and anthrax, serious diseases which afflict cattle, etc.
And pigs, as he notes, are unusually clean when kept as household pets. So we get back to the fact that interpreters don't really know, and their "explanations" often defy their own evidence.
