Toxic shellfish warning extended along coastline
Toxic shellfish warning extended along coastline
Following ongoing shellfish toxin
monitoring the Paralytic Shellfish Poisoning (PSP) warning
has been extended.
The affected area now includes the entire coastline from Whakatane Heads in the Eastern Bay of Plenty, all the way along the coast to Waihi Beach, and up the eastern side of the Coromandel Peninsula to the river at the southern end of Whangamata beach. All harbours, estuaries and islands along this coastline are included in the warning.
“Ongoing monitoring has shown high levels of paralytic shellfish poison present in shellfish along this coastline. Shellfish in the affected area should not be taken or eaten,” says Medical Officer of Health, Dr Phil Shoemack.
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). PSP is caused by natural toxins that are produced by algal blooms and accumulate in shellfish that feed on the algae. Shellfish containing toxic levels of paralytic shellfish poison don't look or taste any different from shellfish that are safe to eat. 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 cooking or eating.
In the last two weeks, 12 people have been reported to Toi Te Ora – Public Health Service with paralytic shellfish poisoning. Eating shellfish affected by paralytic shellfish 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.
Monitoring of toxin levels will continue along the coast and any changes in advice will be communicated accordingly. The public can obtain up-to-date information on the toxic shellfish health warning through these channels:
