Contaminated shellfish are continuing to cause illnesses in several European countries and Hong Kong.

At least 170 people have fallen ill in Helsinki, Finland, after eating oysters in various restaurants in February and March. Cases have also been reported in other Finnish cities.

Norovirus has been found in nine different oyster batches with two from the Netherlands, six from France, and one from Ireland. Importers have withdrawn affected batches from the market.

Officials have tested food from restaurants and taken patient samples, finding norovirus. Some of those sick reported eating oysters.

A report on the outbreak is being prepared for the Finnish Food Authority (Ruokavirasto) and the Finnish Institute for Health and Welfare (THL).

Norovirus is the most commonly identified cause of foodborne outbreaks in Finland. Between 2017 and 2021, oysters caused 11 norovirus outbreaks in which more than 110 people fell ill.

Finland has published four Rapid Alert System for Food and Feed (RASFF) alerts on food poisoning due to norovirus in oysters since late February.

South Korea – S. Korea sees dramatic surge in food poisoning cases this winter

Korea Herald

The number of food poisoning cases involving raw oysters has surged dramatically this winter compared to last year.

According to the Ministry of Food and Drug Safety on Tuesday, a total of 524 cases of food poisoning due to raw oysters were reported between November 2022 and February 2023. This figure is an eightfold increase compared to the same period between 2021 and 2022, which only had 68 cases.

Oysters are rich in minerals and vitamins but can be one of the main sources of the norovirus, which is more common in winter.
