I think it involved sashimi, raw fish. Not sushi, which is vinegared rice, that may or may not be made with sashimi.
Several tourist came down with some kind of worms in their throat about a month after I moved to Hawaii in 1974. Which is why I never dared try it during the four years I lived there. Not until 20 years later long after returned to the mainland. But I limit sashimi to the type made from fast swimming ocean fish. No slow swimming freshwater fish sashimi.
I worked on a salmon seiner in Alaska one summer in the mid 90’s…..on an off day we would accidentally fish for Halibut ($20.00) a pound halibut. Big bottom feeding fish, maybe 2 to 3 hundred pounds….some bigger….we cut them up to put them into the cold hold and there were wormy creatures exiting the flesh….many. Just cook it enough. Worms are protein….
That’s a “no thanks.” Also, be careful of eating the flesh of large predator fish such as grouper or swordfish as their flesh can contain ciguatera, which is a VERY bad food poisoning. I have firsthand experience.
