in think i know what you are talking about. there was a thread about a year ago about the smell of pork. a member said that pork smelled like the feces that they wallow in. now, feces shouldn't have come in contact in any way with the meat, therefore, i doubt it "flavored" it. but i have noticed that occasionally, pork that i made at home had a slightly gamey or unpleasent smell to it, even after cooking thoroughly. sort of like the smell of a dead carcass, but not nearly as bad. so i think it was just the natural gamey odor of an otherwise good piece of pork. it may have been was an anomaly (just one bad pig in the sty), or possibly, from the diet the pigs ate just before butchering.
the only way that i know how to get rid of unwanted smells or strong odors/flavors of meat or fish is to soak it in either whole or butter milk overnight. this works well with shark and bluefish, so it might work with pork. i doubt there's anything you can do after it is cooked, except to spice the heck out of it. lots of hot sauce and peppers should keep your schnozz from detecting it.
