How Long Do Prawns Last in the Fridge?
Keeping your seafood fresh for safe and delicious meals.
Prawns last 1–2 days in the refrigerator when kept fresh or thawed properly.
Prawns are a versatile seafood staple, but their high moisture content makes them highly perishable. To maintain peak quality and safety, prawns must be kept very cold. Whether you just purchased them from the fish counter or pulled them from the freezer, they require immediate attention to prevent bacterial growth. Because they are a safety-critical food, it is essential to monitor their texture and scent closely during storage. Proper refrigeration ensures that these succulent crustaceans remain firm and fresh for your next meal.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
