shellfish poisoning

an acute intoxication caused by ingestion of bivalve mollusks contaminated with the neurotoxin (saxitoxin) secreted by certain dinoflagellates, protozoa that are an important component of marine plankton. One form, paralytic shellfish poisoning, is caused by species of Gonyaulax, and is characterized by paresthesias of the mouth, lips, face, and limbs, nausea, vomiting, and diarrhea; in rare severe cases muscle weakness or paralysis and respiratory embarrassment and death may occur. A self-limited milder form, neurotoxic shellfish poisoning, not associated with paralysis, is caused by species of Gymnodinium.

"This toxin has been found in the Conwy estuary in the past." A Conwy County Council spokesman said: "Routine shellfish sampling by food safety officers from regulatory services revealed a high level of diarrhoetic shellfish poisoning toxin in the mussels on the shore line in Rhos." James Wilson, from Menai Strait company Deepdock, said: "I am sure that sampling will take place across the wider area to ensure that the toxin has not become more widespread.

According to a report in New Scientist, the research, by researchers from the University of South Carolina, suggests that far from degrading soon after the bloom, the neurotoxin that causes shellfish poisoning, domoic acid, sinks to the ocean floor and could poison marine mammals, birds and humans.
