The Pacific geoduck clam is one of the largest burrowing clams in the world. Geoducks can bury themselves so that their siphons stretch 1 meter to the substrate surface. A troubling problem is that high levels of paralytic shellfish poisoning (PSP) have been found in geoducks in Southeast Alaska, most strongly associated with the viscera. The mantle and necks are the usual body parts consumed and PSP concentrations are lower in these parts. Though this situation permits the sale of processed clams with viscera removed, exvessel value for processed clams is significantly less than that for whole, live product.
