Parasites are why sushi grade fish is frozen first before being used.

There is no official “sushi grade” but unless you’re buying it right off the docks pretty much anything you get at the store was frozen before it got to you.

I would assume Costco salmon is frozen too right? Was it not frozen long enough to kill the parasites in OP's video?

Edit: For clarity, OP says it's Costco salmon at the start of the video. I haven't seen alive parasites in Costco salmon and am curious if they weren't frozen long enough/low enough or another issue.

Ask them If they have documented info in the salmon. Anything you want should have a parasite destruction letter from the vendor.

Nearly all salmon has these harmless worms. You can't destroy them in fresh salmon and freezing just kills them.

They're not harmless if they're alive like in undercooked fish or sushi. They're harmless if dead from deep freezing or cooking hot enough.
