FAO and WHO plan meeting on foodborne viruses

Food Safety News

The UN Food and Agriculture Organization (FAO) and World Health Organization (WHO) are set to hold an expert meeting on viruses in food later this month.

The Joint FAO/WHO Expert Meeting on Microbiological Risk Assessment (JEMRA) event, at FAO headquarters in Rome on Sept. 18 to 22, will work on food attribution, analytical methods, and indicators of viruses in foods.

United States-based experts proposed for the meeting are Donald Schaffner, of Rutgers University; Xiang-Jin Meng, at Virginia Tech; Kali Kniel, from the University of Delaware; Lee-Ann Jaykus, at North Carolina State University; and Jacquelina Williams-Woods of the FDA.

In 2022, the Codex Committee on Food Hygiene (CCFH) asked JEMRA to provide scientific advice to inform a review of guidelines established in 2012. This was due to emerging issues associated with foodborne viruses and scientific developments.

Food Safety News

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 Importers have withdrawn affected batches from the market.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.
