Deuteronomy 14:8 said:
The pig, because it divides the hoof but does not chew the cud, it is unclean for you. You shall not eat any of their flesh nor touch their carcasses.
However, regardless of what the bible says, pork is a difficult meat, more so in a hot country, and before refrigerators were invented.
You have to think 2,000 years ago when looking at the bible and, in that time, diseases such as trichiniasis were not understood.
Disregarding all religious arguments on this subject, there is plenty of science to suggest the rules of the bible should be followed.

On a personal note - I used to date a young lady who lived on a pig farm, so saw the beasts rather a lot, thus I can assure poster they're disgusting animals.
We've all heard the phrase, "To eat like a pig", but few actually understand it.
The pigs would rush down their food, spilling quite a lot onto the floor, where they would eat it from when they'd finished the rest.
The fact they'd been pooping there, and the food was well mixed with pig poo, made not the slightest difference.
