Any angler will know that, in some lakes, it seems like every fish is full of worms. I've always dealt with that by frying the crap out of them -- no medium-rare bass for me, sorry. Alternatively, I'm sure they're fine after a few weeks in the freezer.
Rivers seem to be better, with worm presence (or at least, obvious worm presence) being less common. Additionally, I've never seen worms in bottom-feeding fish like catfish and carp.
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
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
I don't think that the Anisakis species discussed in this article would generally be considered microscopic, as demonstrated by various photos included in the article. The Trypanorhyncha larvae are smaller, but also likely to be visible without microscopy as well, on the basis of the scale I'm inferring from the included photos vs. the muscle striation in the tuna.
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.

That's a terrible sensationalist website btw...

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.
