Aaah yes...Sushi, your best source for intestinal worms!
Other than a few uber-high end places that just pay the fines, it's illegal for sashimi (The raw fish part of sushi) to be sold in the USA without deep freezing it first to kill any ickies.....
"Most would be even more surprised to learn that if the sushi has not been frozen, it is illegal to serve it in the United States.
Food and Drug Administration regulations stipulate that fish to be eaten raw -- whether as sushi, sashimi, seviche, or tartare -- must be frozen first, to kill parasites. ''I would desperately hope that all the sushi we eat is frozen,'' said George Hoskin, a director of the agency's Office of Seafood. Tuna, a deep-sea fish with exceptionally clean flesh, is the only exception to the rule."
