I can not comment on baiting hogs much other then I know some guys that really like to use corn with a couple packets of strawberry jello mixed into it.

The "dangerous pork" you hear about is pork that has trichinosis.
It can be killed by either keeping the meat frozen at 5 degrees for approx 30 days or you can cook it to an internal temp of 165.

I am going on my first hog hunt here in april I have done tons of research and I plan on eating my hog if I am lucky enough to kill one. I hope this helps some I included a good link on trichinosis.
