Paralytic Shellfish Poisoning Outbreak

The outbreak of paralytic shellfish poisoning is the worst that has been seen in the Bay of Plenty.

Since 12 December 2012, twenty people have been poisoned by eating shellfish collected from the Bay of Plenty shoreline.

Ten have had to be admitted for hospital care after suffering symptoms ranging from tingling around the mouth to difficulty walking. Four people remain in hospital.

The levels of toxins being reported from routine shellfish sampling, and the number and severity of cases underline that collecting shellfish from the affected area is a significant health risk.

The health warning that was issued in August remains in place. Dr Neil de Wet, Medical Officer of Health, stresses the importance of heeding the health warning and making sure that friends and visitors to our area are made aware of the risk.

“Tell your family, whanau, friends and tourists that collecting shellfish is not safe at present. If you see someone collecting shellfish remind them – we don’t want anyone else in hospital this holiday”.

As a reminder the Medical Officer of Health strongly advises against the collection of shellfish from Tairua on the east coast of the Coromandel Peninsula, south to Waihi Beach and along the Bay of Plenty coast to Whakatane Heads in the Eastern Bay of Plenty. The warning includes Tairua Harbour as well as Tauranga Harbour, Maketu and Waihi estuaries, Matakana and Motiti Islands, and all other inshore islands along this coastline.

The health warning applies to all bi-valve shellfish including mussels, pipi, tuatua, cockles, oysters, scallops as well as cat’s eyes and kina (sea urchin). Shellfish in the affected area should not be taken or consumed. Paua, crayfish and crabs can still be taken but as always, the gut should be removed before cooking.

Consumption of shellfish affected by the paralytic shellfish toxin can cause numbness and tingling around the mouth, face or extremities; difficulty swallowing or breathing; dizziness; double vision; and in severe cases, paralysis and respiratory failure. These symptoms usually occur within 12 hours of a person consuming affected shellfish. Anyone suffering illness after eating shellfish should seek urgent medical attention.

Scoop Business: Bathurst Gets Nod For DoC Access To Denniston Mine

Conservation Minister Nick Smith has approved access over conservation estate land for Bathurst Resources to develop an open cast coal mine on the Denniston Plateau, above Westport, to the dismay of environmental opponents.

The timing for Smith’s move avoids Bathurst having to resubmit applications for access agreements under the revised Crown Minerals Act, which comes into force tomorrow and would have required public consultation.

The announcement lands in the middle of delicate negotiations between the company, environmental groups and other interested parties that could pave the way to a broader agreement on the Escarpment proposal, whose resource consents are still subject to court appeals. More>>
