A spike in cases of food poisoning has been linked to people consuming raw mussels from the Coromandel area.
New Zealand Food Safety is urging people to ensure they cook raw mussels thoroughly, as raw or undercooked mussels can make people sick.
Director of food regulation Paul Dansted said eating raw shellfish always carried a risk for food-borne illnesses.
“Cooking kills the marine micro organism Vibrio parahaemolyticus, which occurs naturally throughout the world,” he said.
