Seafood is a perishable product that requires a few precautions. Store it in a cool place, between 5 and 15°C, away from heat. As for oysters, keep them flat with the rounded side facing downwards so that they retain their natural juices, and under no circumstances should you submerge them in fresh water. They are best eaten within 5 to 10 days of the packaging date, and should only be eaten if they are tightly closed or close when touched.
