Costco Salmon for sushi? Yes or big No?

Ive seen one video where there was a warm in the costco salmon and since then im kinda…. meuhhhh….
I still bought it from costco cause its cheap but should homemade sushi be made with like top fish grocery quality?

PS: Im a total beginner in homemade sushi

Edit: Here is the video Im talking about (warning: 🤮 https://www.youtube.com/watch?v=UM4RNIAnv5s )

Edit 2: Ok so 2 questions form all the answers:
1. What happen if you get a worm like this in your belly? Will it die or will it stay alive?
2. Many people say 'Flash frozen', so should I freeze it 7 days to be sure? Anyone doing this? I have no idea if it was frozen before…
