All bivalve molluscan shellfish including clams, mussels, oysters, geoducks, and scallops can contain PSP toxins.

While crab-meat has not been found to contain PSP toxins, the guts/butter of crabs has been found to contain PSP toxins; therefore, consumers of non-commercially harvested crab should clean the meat thoroughly, discard the guts/butter before boiling, and avoid drinking the broth in which the crab was boiled.

Predatory gastropods such as moon snails can also become toxic and thereby pose a risk to humans
