The little roundworms, a.k.a. "codworms," don't bother me any. I've found them in all types of salmon and steelhead that I've eaten. Also, I've found the skin rash prevalent on silvers is merely cosmetic and does not affect the eating, that is of course assuming that the fish has been skinned prior to consumption. What grosses me out is the white globule-like organism that infests kings and silvers, sometimes so badly it relegates the entire fish into crabbait.
