Paralytic shellfish poison is a marine biotoxin, produced in single celled marine protozoa of the order Dinoflagellata. This poison accumulates in the tissue of bivalve shellfish that have ingested certain species of dinoflagellates of the genus Gonvaulax or closely related genera. Ordinary cooking does not insure safety of shellfish since the poison is very stable and is not destroyed completely by the usual heat treatments.
Articles meeting the above criterion represent a potential health hazard.
Consequently, recall is the action of choice. Material between asterisks is new or revised.
