I am from an older generation, I have never nor will ever eat sushi :)
But the cold kills the parasites. Its why "sashimi grade fish" is safe.
This term has no legal definition and is unregulated. A fish caught, cut, and thrown on a plate as sashimi could be called sashimi grade having never touched a freezer to kill off parasites.
Never too old to try something that is incredibly delicious. :-) My mom (born 1943) introduced me to sushi. Can't blame generation there.
I can assure you by direct experience than the adults colonies could pass for a noodless dish at the first look.
You're really missing out. It's probably my favorite food on the planet, lol.
