Mentioned this on the air. The following video might make your stomach turn. Also, if you like fish, don't watch the video below.
But, a South Carolina guy was shopping at a local Costco store and found a WORM inside the package of "fresh" fish.
Guy from Costco said that finding these little wormy things is not uncommon, but when cooked, the little guy will pose no harm to the food. That actual package of fish was not sold, however.
Good thing I don't like seafood.
