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
It has already been known for a long time fish, and in particular tuna, carry a lot of worms and parasites, which is why freezing rules are in place in pretty much every country.
For example here are EU regulations regarding freezing Tuna
Bonus protein
Futurama covered this. https://en.wikipedia.org/wiki/Parasites_Lost
Sell it as "protein tuna" and you can even markup the prices!
I wonder how this will affect sushi ? Could people eating that get infected ? Seems in very rare cases the answer is yes.
I am from an older generation, I have never nor will ever eat sushi :)

Yeah these are microscopic
It won’t. sushi is flash frozen for exactly this reason
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.
