It doesn't, really - this is a known hazard. You want fish that was flash-frozen very rapidly after harvesting. It's tastier and it kills (these types of) parasites. Which is basically what you're going to get at any decent sushi place.

Never too old to try something that is incredibly delicious. :-) My mom (born 1943) introduced me to sushi. Can't blame generation there.

All sushi fish is frozen for some number of days to kill anything. I guess the only risk would come from somebody not doing there job properly, but I'm sure a sushi chef would notice a living worm parasite in the fish they are cutting

You can eat Sushi that is cooked, and there are even vegetarian rolls that don't have any fish. Sushi is quite good.

It won’t. sushi is flash frozen for exactly this reason

Assuring than no undesirable worms reach the table, ever, is the main reason of Japanese having developed sushi. Every fish in Japan destined to be served as sushi is ultra frozen first

> have never nor will ever eat sushi

You're really missing out. It's probably my favorite food on the planet, lol.

It's not a generational thing, at least not anymore. People older than you were eating sushi back when Western businesses started intensely transacting with the Japanese in the late 20th century (60s, 70s, 80s).

So what makes raw fish safe is that the fish is froze at a temp for a period of time. Its different depending on temp and duration.

But the cold kills the parasites. Its why "sashimi grade fish" is safe.
