Mattilsynet

A La Carte Produkter AS asks consumers who have bought the product to throw it away or return it to where it was bought. In the delis, oysters are sold unpackaged and without labelling. If you are unsure whether you have bought oysters from the affected lots, you can contact the point of sale, or throw them away.

Food poisoning with Norovirus can cause acute nausea, vomiting, abdominal pain and/or diarrhoea. In addition, you can get flu-like symptoms such as fever, muscle and joint pain and headache. The disease is usually mild and goes away on its own after 1-3 days in otherwise healthy people. 

Oysters are often eaten raw without heat treatment, and from nature’s side, oysters can concentrate viruses by filtering the water they live in. Oysters can thus make us sick when eaten. Norovirus is the most common cause of what we usually refer to as “acquired sickness”, and in periods of high incidence of Norovirus in the population, the risk of getting sick from eating oysters also increases.

Boiling and frying kill Norovirus, but it is uncertain whether steaming has a sufficient effect.
