At the grocery store Winco I have seen inside the package of a fresh side of salmon a little white worm crawling around. Their produce is otherwise seemingly very fresh and I've never had quality issues buying from them. I have no idea if that worm was at all dangerous to humans, but ever since then I have assumed that all of the salmon I eat is similarly affected and I am extra careful with preparation.
