If you ask for sashimi grade fish, you'll avoid this problem. You can also avoid the problem by staying away from salmon which is a dirty fish, prone to worms. Tuna is a cleaner fish. It's save. Atlantic caught fish are less likely to have worms than Pacific caught fish. (Fewer marine mammals = cleaner fish) You can eat farm raised fish, which is less likely to be infected than wild caught fish.
Tuna is high in mercury. You can't win. Animals have parasites, too. Just cook everything well and go to reputable sushi restaurants for your occasional raw fish fix.
