Yes. All oysters are shipped live, carefully selected and prepared to maintain their full freshness and quality.

Oysters are live bivalves, so sudden changes in temperature can affect their condition.We recommend storing the oysters in their original box, refrigerated at a stable temperature between 5°C and 10°C.It is important to always keep the oysters with the concave side facing downwards, so that the water inside the shell continues to keep the product moist until the moment of consumption.

To enjoy their full freshness and quality, it is recommended that you consume the oysters as soon as possible.Depending on the variety and correct storage, they can remain in perfect condition for approximately one week from the date of delivery.

Closed oysterIf the oyster offers no resistance when you insert the blade of a knife between the shells, it is likely that the shellfish is dead.IMPORTANT: A strong, unpleasant smell when opening the shell indicates that the product is spoiled. In this case, it is recommended that you disinfect the opening tools and any surface that has come into contact with the oyster’s water.Open oysterIf the oyster looks dry, comes away easily from the adductor muscle, or contains no water inside the shell, it is dead. To check if the oyster is still alive, gently stimulate the edge of the mantle with the tip of the knife. The mantle will react slowly by retracting slightly.IMPORTANT: the movement of the oyster’s mantle is very subtle, slow and barely perceptible. Another way to check is to add a few drops of lemon juice to the edge of the mantle. The acidity will cause a slight natural reaction in the oyster, similar to that produced by stimulation with the knife. IMPORTANT: this reaction may be minimal and very difficult to detect.
