Bay of Plenty shellfish remain contaminated with paralytic shellfish poison, says Toi te Ora Public Health's Medical Officer of Health Dr Neil de Wet.
'The health warning is still in place,” says Neil.
'The most recent tests were carried out on Sunday, Monday and Tuesday. They already show the levels are still in the area of the health warning.

'The levels are still over the limit for human consumption and there are no signs showing anything is reducing,” says Neil.
The health warning extends from the Coromandel coast to the Whakatane River Mouth, including inshore islands, harbours and estuaries. It has been in place since December.
Shellfish and seawater samples in the Bay of Plenty District are tested every week for contamination with biotoxins. Two clear weeks are required before any existing health warning is removed.
The health warning affects all bi-valve shellfish such as mussels, toheroa, pipi, tuatua, cockles, oysters, scallops, catseyes, pupu and kina.
Toi te Ora, Public Health advice is to collect shellfish only from areas where the seawater is clean and uncontaminated.
Proper handling, storage and cooking can also help lower the risk of illness. The gut of paua, crayfish and crabs should always be removed before cooking.
Shellfish poisoning symptoms may include: Numbness and tingling around the mouth or face, difficulty swallowing or breathing, dizziness, double vision, and in severe cases paralysis and respiratory failure. The symptoms occur within 12 hours and anyone experiencing the symptoms should contact their doctor.
Gastrointestinal symptoms may occur if shellfish are contaminated with bacteria and viruses.
