The Bay of Plenty DHB is warning locals not to collect or eat shellfish

Jim is fervently reminding the public the health warning due to shellfish toxins along part of Bay of Plenty coastline is still in place.

'I've had reports that people have been continuing to eat shellfish and have felt unwell after doing so.

'The toxins can make people very ill and I strongly advise not collecting or consuming shellfish from any part of the affected area.”

Jim says these are the first cases that have been reported since the Paralytic Shellfish Poisoning (PSP) outbreak in the Bay of Plenty in late 2012.

The PSP toxin levels in shellfish from this area are rising and he urges people to heed the warning and make sure their visitors and friends are aware.

On November 28 a health warning was issued advising against the collection of shellfish from Mount Maunganui and along the Bay of Plenty coast to Whakatane Heads in the Eastern Bay of Plenty.

The warning includes all islands and estuaries along this part of the coastline.

The health warning applies to all bi-valve shellfish including mussels, pipi, tuatua, cockles, oysters, scallops as well as cat's eyes, snails and kina (sea urchin), and they should not be taken or eaten.

Shellfish containing the toxin don't look or taste any different from shellfish that are safe to eat, while cooking or freezing the shellfish does not remove the toxin.

Paua, crayfish and crabs can still be taken but as always, the gut should be removed before consuming.

Consumption of shellfish affected by the PSP toxin can cause numbness and tingling around the mouth, face, hands and feet; difficulty swallowing or breathing; dizziness; double vision; and in severe cases, paralysis and respiratory failure.

These symptoms can start as soon as 1-2 hours after eating toxic shellfish and usually within 12 hours. Anyone suffering illness after eating shellfish should seek urgent medical attention.
