Shellfish biotoxin alert for Port Waikato

A shellfish biotoxin alert has been issued by the Ministry of Primary Industries for the coastal area from Port Waikato southward to Papanui Point, and including Raglan Harbour. The reason for the alert is the possibility of contracting paralytic shellfish poisoning (PSP).

Do not collect or eat shellfish from areas where shellfish biotoxin warnings have been issued.

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.

If you get sick after eating shellfish

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
  • advise your nearest public health unit
  • keep any leftover shellfish for testing.
