High levels of poison have been measured in shellfish in the Papamoa area, as the ban on collecting or eating toxic shellfish from Bay of Plenty shores continues.
Twelve people were reported to Toi Te Ora Public Health Service with paralytic shellfish poisoning during the first two weeks of December but luckily no more since then, Medical Officer of Health Dr Jim Miller said.
"There's really quite high levels of shellfish poison in the tests coming back ... So although we've been lucky that we haven't had any more cases, the health warning remains."
Recent tests from the middle of the coastline in the Papamoa area had come back with high levels of poison, he said.
He hoped Bay locals would let visitors know about the warning.
