Warning for consumers after spike in food poisoning from undercooked shellfish

A rise in cases of food poisoning resulting from undercooked seafood has prompted a warning from the Ministry for Primary Industries, Stuff reports. Since November 15, there have been 36 cases of vibrio parahaemolyticus, a bacterium located in shellfish, reported around New Zealand. The ministry would normally expect to see only three or four during that time. The ages of the people affected were between 23 and 90. Twelve of the cases were hospitalised.
