Bacon and pork is actually an unclean food according to the Bible, not just because God said so, but rather because pigs eat just about anything and that stuff gets into the pig's meat, and when we consume that meat, that bad stuff goes into us. So pork, even when cooked, can contain stuff like heavy metals and other contaminants, At first, I thought it was crazy, until my dad explained it all to me, and now it makes much more sense to me.
