USA – Whatcom County Beaches Closed Due to Paralytic Shellfish Poisoning

Food Poisoning Bulletin

According to a press release from the Whatcom County Health Department, Whatcom County beaches have been closed to recreational shellfish harvest because the paralytic shellfish poisoning (PSP) biotoxin has reached unsafe levels in molluscan shellfish in Drayton Harbor.

New Zealand – Shellfish biotoxin alert – Nydia Bay in the Pelorus Sound

MPI

The Ministry for Primary Industries (MPI) today issued a public health warning advising the public not to collect or consume shellfish harvested from all of Nydia Bay in the Pelorus Sound.

Routine tests on shellfish samples taken from this region have shown levels of Paralytic Shellfish Poisoning (PSP) toxins above the safe limit of 0.8 mg/kg set by MPI. Anyone eating shellfish from this area is potentially at risk of illness.

Pāua, crab and crayfish may still be eaten if the gut has been completely removed prior to cooking, as toxins accumulate in the gut. If the gut is not removed its contents could contaminate the meat during the cooking process.

Symptoms typically appear between 10 minutes and 3 hours after ingestion and may include:

  • numbness and a tingling (prickly feeling) around the mouth, face, and extremities (hands and feet)
  • difficulty swallowing or breathing
  • dizziness
  • headache
  • nausea
  • vomiting
  • diarrhoea
  • paralysis and respiratory failure and in severe cases, death.

If anyone becomes ill after eating shellfish from an area where a public health warning has been issued, phone Healthline for advice on 0800 61 11 16, or seek medical attention immediately. You are also advised to contact your nearest public health unit and keep any leftover shellfish in case it can be tested.

Monitoring of toxin levels will continue and any changes will be communicated accordingly. Commercially harvested shellfish – sold in shops and supermarkets, or exported – is subject to strict water and flesh monitoring programmes by MPI to ensure they are safe to eat.

Research – As warming waters make shellfish toxic, a way of life becomes deadly for Native Alaskans.

Grist org

This summer, independent shellfish testing sites all over the state reported spikes in toxin levels, possibly related to the historic high temperatures in the water surrounding Alaska. And those warming waters are creating the ideal conditions for the algae that produce the toxin to propagate year-round, some researchers say.

New Zealand -Marine biotoxin in shellfish for Waihi Beach in the Waikato/Bay of Plenty region

MPI

The Ministry for Primary Industries (MPI) today issued a public health warning advising the public not to collect or consume shellfish harvested from the southern end of Pauanui Beach down to the northern tip of Mount Maunganui, including the Tauranga Harbour.

Routine tests on shellfish samples taken from this region have shown levels of paralytic shellfish poisoning (PSP) toxins above the safe limit of 0.8 mg/kg set by MPI. Anyone eating shellfish from this area is potentially at risk of illness. Please help keep your whānau safe over the Christmas break and avoid collecting shellfish from the affected area.

Due to currents and prevailing winds going in the opposite direction, the presence of toxic shellfish are not believed to be related to the recent eruption of White Island.

Canary Islands – Ciguatera outbreak reported in the Canary Islands

Outbreak News Today File:Gambierdiscus toxicus NOAA.png

Health officials with the Government of the Canary Islands have reported a possible outbreak of ciguatera after finding six cases of food poisoning after consuming black medregal (amberjack) in La Victoria de Acentejo, according to a El Dia report (computer translated).

Ciguatera is not unknown in the Canary Island reporting several cases annually and some 20 outbreaks in the past decade.

More than 400 species of fish, including barracuda, black grouper, blackfin snapper, cubera snapper, dog snapper, greater amberjack, hogfish, horse-eye jack, king mackerel, and yellowfin grouper have been implicated in this food borne illness that’s relatively common in several areas of the world.

This toxin is the result of the accumulation of marine algae and the toxins they produce passing up the food chain. These marine algae hang on to dead coral and seaweed. They are then eaten by herbivore fish which are subsequently eaten by predatory reef fish which concentrates the toxin in its tissue. People get this food borne toxin from eating these contaminated larger fish. The reef fishes are more likely to get contaminated during storms and other turbulence.
