Paralytic shellfish poisoning (PSP) is a serious illness caused by eating shellfish contaminated with dinoflagellate algae that produce harmful toxins. COVID-19 is an emerging, rapidly evolving situation.Although voltage-gated sodium channels (Na v ) are the cellular target of paralytic shellfish poisoning (PSP) toxins and that patch clamp electrophysiology is the most effective way of studying direct interaction of molecules with these channels, nowadays, this technique is still reduced to more specific analysis due to the difficulties of transforming it in a reliable throughput system.
Algae blooms do not usually occur during winter months in the UK.The routine monitoring for the presence of toxin producing plankton in shellfish production and relaying areas, and biotoxins in bivalve molluscs, is a requirement of Regulation (EC) No 854/2004, which sets out official controls on products of animal origin intended for human consumption.The Food Standards Agency (FSA) is the body with overall responsibility for the official monitoring programme for marine biotoxins in live bivalve molluscs. The monitoring programme involves testing bivalve molluscs such as Oysters, Mussels, Cockles etc and water from classified production areas.

These are filter feeders and can accumulate the potent neurotoxins, all related to the parent compound saxitoxin, which are produced naturally by certain species of microscopic algae.

Some of these toxins are 1,000 times more potent than cyanide, and toxin levels contained in a single shellfish can be fatal to humans. What are the symptoms of PSP? At this point there is nothing to indicate that species sold for human consumption such as brown crabs or lobster are affected but as a precautionary measure we are sampling a range of marine animals to ensure that any on-going PSP contamination is identified.’.There is no risk from the presence of PSP toxins in seawater, and the test results from sampling undertaken so far does not indicate that such contamination currently exists. These are filter feeders and can accumulate PSP toxins, which are produced naturally by certain species of microscopic algae.

Testing carried out by the Centre for Environment, Fisheries and Aquaculture Science (Cefas) found high concentrations of PSP toxins in starfish (1,500 micrograms [PSP] per kilogramme of tissue tested) and dab (566 [PSP] per kilogramme of tissue tested) connected with the incident at Cley. 2013 Mar 27;11(4):991-1018. doi: 10.3390/md11040991.Collaço RC, Hyslop S, Rocha T, Dorce VAC, Rowan EG, Antunes E.Arch Toxicol.
