New Zealand – Shellfish biotoxin alert – South Island West Coast region

MPI Mussels

The Ministry for Primary Industries (MPI) today issued a public health warning advising the public not to collect or consume shellfish harvested from between Hector south to Greigs on the South Island West Coast.

Routine tests on shellfish samples taken from Cape Foulwind has shown levels of diarrhetic shellfish toxins above the safe limit of 0.16 mg/kg set by MPI.  Anyone eating shellfish from this area is potentially at risk of illness.

Ongoing testing will continue and any changes will be communicated accordingly.

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.

New Zealand – Shellfish biotoxin alert – Northland East Coast region

MPI

The Ministry for Primary Industries (MPI) today reduced the area affected by the public health warning against collecting shellfish on the Northland East Coast to the area between Kokota (The Sandspit) and Farmer Point.

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.

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.
