New Zealand – Public health warning: shellfish biotoxin alert for Nydia Bay/Pelorus Sound area in the Marlborough Sounds

Posted on July 6, 2023 by | Leave a comment

MPI

New Zealand Food Safety today issued a public health warning against collecting shellfish from the Pelorus Sound area in the Marlborough Sounds. The area includes Pelorus Sound from Hikapu Reach at Koutuwai Point up to Spencer and Capsize Points.

Paralytic Shellfish Toxins have been detected in shellfish at Nydia Bay at levels several times above the safe limit set by MPI. There is extreme risk from consuming shellfish in this area.

Mussels, oysters, tuatua, pipi, toheroa, cockles, scallops, catseyes, kina (sea urchin) and all other bivalve shellfish should not be eaten.

Note that cooking shellfish does not remove the toxin.

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.

Public warnings about toxic shellfish

We test shellfish and seawater for toxic algae every week from popular shellfish gathering areas around New Zealand. If the shellfish are not safe to eat, we issue public health warnings and put up signs at affected beaches.

Norway -Crab shells in Agder: DSP below limit value

Posted on September 23, 2022 by | Leave a comment

Matportalen

On 22 September, the Norwegian Food Safety Authority received a response to new samples of crabs in Agder. The random samples show that diarrhea toxin (DSP) in the crabs is now below the limit value, but there is no guarantee that all crabs in the area are below the danger limit. The Norwegian Food Safety Authority recommends following the mussel warning, as the crab likes to eat mussels.

Earlier in September, the Norwegian Food Safety Authority found high concentrations of the algae poison DSP (Diarrhetic Shellfish Poisoning) in crab from Agder, and thus warned people to eat the contents of crab shells.

DSP is one of the most common types of mussel poisoning in Norway. Once the crab has eaten mussels with DSP, the crab becomes poisonous to people who eat it. DSP causes diarrhoea, nausea, vomiting and abdominal pain. It takes from half an hour to a few hours from the time you eat until you get sick. The symptoms disappear by themselves after 2-3 days.

Since the beginning of July this year, high levels of the algal toxin DSP have been detected in mussels along the Sørland coast and in Agder.

New Zealand – Public health warning for shellfish reduced for West Coast, North Island – PSP Toxins

Posted on September 13, 2022 by | Leave a comment

MPI

New Zealand Food Safety today reduced a public health warning against collecting shellfish in the Waikato and Taranaki region. The public health warning now extends from Albatross Point south to Oakura Beach and no longer applies to Kawhia and Aotea Harbours. More testing is being undertaken to determine the levels of paralytic shellfish toxins in the affected area.

Routine tests on shellfish samples taken from the Aotea/Kawhia Harbour area have shown levels of Paralytic Shellfish Poisoning (PSP) toxins are now within the safe limit of 0.8 mg/kg set by New Zealand Food Safety.

See a map of the warning

Mussels, oysters, tuatua, pipi, toheroa, cockles, scallops, catseyes, kina (sea urchin), and all other bivalve shellfish should not be eaten.

Note, cooking shellfish does not remove the toxin.

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.
