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.

Common questions

How long can I keep prawns in the refrigerator?

Prawns last 1–2 days in the refrigerator when kept fresh or thawed properly. To maintain quality, ensure they are stored in a clean, airtight container.

Can I freeze prawns to extend their life?

Yes! Prawns can be frozen for 3–6 months. For the best results, pat them dry before freezing to prevent freezer burn and preserve their texture.

How can I tell if the prawns have gone bad?

Sage's Verdict: If you notice a strong ammonia smell, a slippery/slimy coating, or if the flesh feels mushy rather than firm, discard them immediately.

Is it safe to eat raw or undercooked prawns?

No, it is not recommended to eat raw or undercooked prawns. To ensure safety and the best flavor, always cook prawns thoroughly until they are opaque and firm.
