MDPI

North Island warnings

Hawke’s Bay

Reason for alert Paralytic Shellfish Poisoning (PSP)

Check the symptoms of PSP

Date warning issued 16 June 2021

Media release

Affected area From the Mohaka River mouth, south to Cape Kidnappers.
Shellfish affected Mussels, oysters, tuatua, pipi, toheroa, cockles, scallops, catseyes, kina (sea urchin), and all other bivalve shellfish.

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 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.
Other information Paralytic shellfish toxins have been detected in shellfish from Pania Reef at levels over the safe limit of 0.8mg/kg set by MPI. Ongoing testing will continue and any changes will be communicated accordingly.
