The Ministry for Primary Industries today extended the public health warning against collecting shellfish in the Bay of Plenty region.

The warning now covers the coastline from the northern end of Waihi Beach south-eastward to Opape.

Routine tests on shellfish samples taken from sites in this region have shown levels of Paralytic Shellfish Poisoning 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. Cooking shellfish does not remove the toxin.

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

Paua, 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.

Is SH2, between Katikati and Tauranga, a dangerous stretch of road?

Yes, there are too many cars on it and it’s not designed to handle that sort of traffic volume.
No, people just need to slow down and pay attention to their driving.
