How Long Do Prawns Last in the Fridge?
How long do prawns stay fresh in the refrigerator?
Prawns last 1–2 days in the refrigerator when kept fresh or thawed properly.
Prawns are a highly perishable seafood staple due to their high moisture content. To maintain both food safety and optimal texture, they must be stored at consistent, very cold temperatures. Whether you have just purchased them from a seafood counter or have recently thawed them, immediate refrigeration is necessary to prevent rapid bacterial growth. Because prawns are considered a safety-critical food, monitoring changes in scent and surface texture is essential for preventing foodborne illness. Proper storage in an airtight container helps preserve their succulent quality and ensures they remain safe for consumption.
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 should be consumed within 1–2 days of purchase or thawing. Storing them in an airtight container helps maintain freshness during this window.
Can I freeze prawns to extend their shelf life?
Yes, prawns can be frozen for 3–6 months. For the best quality, pat them dry before placing them in a freezer-safe bag to prevent freezer burn.
How do I know if prawns have gone bad?
Check for three main signs: a strong ammonia or fishy smell, a slippery/slimy texture on the shell or flesh, and a dull, mushy appearance.
Is it safe to eat raw prawns?
It is not recommended to consume raw or undercooked prawns. Always cook them thoroughly until the flesh is opaque and firm to ensure safety.
When handling seafood, prioritize safety above all else. If you notice any unusual odor or a slimy texture, discard the prawns immediately.
