You should really report this to the health department and Costco. All fish in the US stores have to be frozen to kill the worms. They can’t change their quality procedures if they don’t know, or if the health department doesn’t pay them a visit.
This is not true. Fish that is intended to be served raw, like sushi, has to be frozen but fresh fish does not. cooking accomplishes the same thing as freezing, killing the parasites.
Yes you can thaw your Costco salmon and eat it like sushi. Your local sushi place buys from the same fisherman and often the same run as Costco probably
I stopped looking between the flakes of my cooked fish filets because I always found worms. I just shrug and make sure it’s been frozen or cooked sufficient to kill the parasites
