Public health warning - marine biotoxin warning extended in the Bay of Plenty
The Ministry for Primary Industries (MPI) today issued a public health warning advising the public not to collect or consume shellfish harvested from the mouth of the Otahu River at the southern end of Whangamata Beach, southwards all the way to the Whakatane Heads.
The area includes Tauranga Harbour, Maketu and Waihi estuaries, Matakana and Motiti Islands, and all other islands along this coastline.
Routine tests on shellfish samples taken from this region have shown levels of Paralytic Shellfish Poisoning (PSP) toxins of up to 2.3 mg/kg. This is 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
- 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.
