483 Rue Benjamin Moloise, Béthune, 62400 Hauts-de-France, France

We picked up a box at the Auchan Béthune sushi stand on 24/01/2023 around 13/14h.
Since that meal we have had severe stomach pain, vomiting, and fever.
I often have sushi there and everything was fine but now it's horrible.
For 4 days, we have not been able to eat without having nausea and violent stomach spasms | Symptoms: Nausea, Vomiting, Fever, Stomach Pain, Muscle Spasms
