Eating raw pork was very dangerous years ago, in fact could be deadly then. Pigs are now treated for parasites all during their life so the chances of getting trichinosis is very low.
There are about 20 cases in the U.S. a year and not all are from eating pork. I could not find a number from eating pork processed for stores but I bet that number is zero or near zero. People get it now from bear meat or pork from pigs they raise and don’t properly treat for worms. Medical care has also progressed and death even if you get trichinosis is very rare, most are successfully treated.
You can actually get several things from eating any meat that is not well done, but no where near as likely to happen now with the way animals are cared for and meat is kept cold and cooked properly. It is possible so many doctors still don’t recommend eating any meat other than well done. They do know the real odds though so I have seen many doctors eat rare or medium rare steaks.
I always thought the Kosher laws came about because of middle eastern heat and the danger of eating pig...
