Shellfish poison cases on the rise

By Kristin Macfarlane


The number of people in Rotorua poisoned by toxic shellfish has increased to six.

On Saturday, Toi Te Ora Public Health said  five people had presented to Rotorua Hospital with symptoms of toxic shellfish poisoning with a further two unrelated cases seen at Tauranga Hospital. Each person affected had eaten shellfish collected from the coastline between Mount Maunganui and Papamoa.

Last night, medical officer of health Dr Neil de Wet told The Daily Post that number had increased to 15.

In Rotorua, he said, six people had suffered shellfish poisoning after collecting shellfish along the coastline from Mount Maunganui and Papamoa. Five had been admitted to Rotorua Hospital but had since been discharged.

"There was also one other case who didn't require attention,'' Dr de Wet said.

One person had also presented to Whakatane Hospital but didn't need medical attention, he said.

In Tauranga, eight people had presented to Tauranga Hospital, five were admitted and two were in a serious but stable condition.


"There are two that are being monitored closely.''

Dr de Wet believed those from Rotorua were from one family group.

He said the poisoning highlighted the importance of following health warnings.

"Although unfortunate, it's a good reminder that this can be a very serious illness,'' Dr de Wet said.

A health warning is in place from Tairua on the Coromandel Peninsula, south to Waihi Beach and along the Bay of Plenty coast to Whakatane. This includes Tauranga Harbour, Maketu and Waihi estuaries, Matakana and Motiti islands, and all other inshore islands along the coastline.

The health warning applies to all bivalve shellfish, including mussels, pipi, tuatua, cockles, oysters, scallops as well as cat's-eyes and kina (sea urchin).

Shellfish in the affected area shouldn't be eaten. Paua, crayfish and crabs can still be taken but the gut should be removed before cooking.

Toxin symptoms ranged from tingling round the mouth and face, tingling of the skin, mild weakness, diarrhoea and vomiting. In severe cases, people can suffer paralysis and respiratory failure. Symptoms usually occur within hours of a person consuming affected shellfish. Anyone suffering illness after eating shellfish should seek medical attention.
