@Rob --
But they don't. Some percentage of the pork on store shelves has trichinella in it, but most people don't become infected by eating it? Why is that? Because they cook it thoroughly and that kills all of the parasites(and it's not like rare pork tastes all that good anyways, not like a rare steak at least).
Again, you're wrong. I'd be willing to bet you one million in cold, hard cash that if you gave me a piece of pork that was infected with trichinella I could easily make it safe for consumption without any special preparations. That's how sure I am of the science involved in this.
Well by that logic we should just cut meat completely out of our diet all together as it can all hold parasites and bacteria. Chicken is infamous for causing salmonella(and has been for as long as we've been eating it), but I don't see any injunction, god given or otherwise, in the bible about not eating poultry. There are hundreds of parasites that you can get by eating meat, and usually cooking is a very effective way of killing them and preventing that(there are, of course, a few exceptions).
1. I didn't just say "cook the meat", you left out a very important word out at the end of my statement. What I actually said was to cook the meat "thoroughly". In other words you have to cook it through in order to ensure that all of the parasites are dead, and the fact that I've been eating pork all of my life and have never suffered an infestation means that the preventative treatment works. It's persistence in humans is not because eating pork is dangerous but because a large percentage of humans are either ignorant(they don't know any better) or stupid.
2. Trichinella wasn't even identified until the mid 1800s which means that the pork injunction in the bible couldn't have possibly been to prevent infection. That was back when people still thought of illness as a sign of their god's disfavor(or sorcery, depending on where you went). No, we already have an explanation for the injunction that doesn't require ancient nomads to possess knowledge that we know for a fact that they didn't have. If you've never slaughtered a pig before(and I'd be willing to bet that most people here haven't) then you wouldn't know, but the death wails of a pig are hauntingly reminiscent of human screams of pain and dead swine flesh smells eerily like dead human flesh. Combine that with the well documented fact that pork tastes just like human(to the point where various cannibalistic tribes call human "long pig") and it's easy to see why a superstitious desert tribe would shy away from eating pork.
Sorry, but as an explanation for the injunction, preventing parasitic infection doesn't add up, especially when you can just cook out any parasites that are in the meat.
