Raw shrimp lasts only 1 to 2 days in the refrigerator when stored at or below 40°F (4°C), and 3 to 6 months in the freezer at 0°F (-18°C). Shrimp is one of the most perishable foods in your kitchen, so keeping it cold, sealed, and dated is what stands between a great meal and a case of food poisoning. Below you will find exact fridge and freezer times for raw and cooked shrimp, how to spot spoiled shrimp (ammonia smell, black spots, slimy shells), and how to thaw, refreeze, and cook it safely.
| Shrimp | Storage | Temperature | Keeps for |
|---|---|---|---|
| Raw | Refrigerator | 32°F to 40°F (0°C to 4°C) | 1 - 2 days |
| Raw | Freezer | 0°F (-18°C) or below | 3 - 6 months |
| Cooked | Refrigerator | 32°F to 40°F | 3 - 4 days |
| Cooked | Freezer | 0°F (-18°C) or below | Up to 3 months |
How Long Does Raw Shrimp Last in the Fridge?
Keep fresh raw shrimp in the coldest part of your fridge, ideally at or below 40°F (4°C). Under the best conditions, raw shrimp stays good for 1 to 2 days. Eat it or freeze it within this window to avoid spoilage and food poisoning. This is a shorter shelf life than most people expect: raw shrimp held for 3 days is already at the edge of safety, and shrimp left in the fridge for 5 days should be discarded even if it looks fine, because harmful bacteria grow long before the smell or color changes. If you need to keep shrimp longer than two days, freeze it right away.
| Storage Method | Temperature | Duration |
|---|---|---|
| Refrigerator | Below 40°F (4°C) | 1 - 2 days |
What Affects Shrimp Shelf Life
Several things change how long raw shrimp lasts in the fridge. Knowing these helps you keep your shrimp fresh for the full two days.
- Temperature: Keep raw shrimp between 32°F and 38°F. Warmer temperatures make it spoil faster. Use a refrigerator thermometer to confirm the setting.
- Freshness at purchase: The fresher the shrimp when you buy it, the longer it will last at home.
- Storage method: Airtight containers or vacuum-sealed bags block air and germs, slowing spoilage.
- Handling: Wash your hands and utensils before and after touching shrimp to avoid cross-contamination.
| What Affects Shelf Life | Impact on Shrimp |
|---|---|
| Temperature | Keep between 32°F and 38°F |
| Freshness | Fresher shrimp lasts longer |
| Storage Method | Airtight containers help |
| Handling | Prevents cross-contamination |

How to Tell if Raw Shrimp Has Gone Bad
Spotting bad shrimp before you cook it saves you from a nasty surprise. Check all four of these signs, and when in doubt, throw it out:
- Smell: Fresh shrimp smells clean, mild, and like the ocean. If it reeks of ammonia or has a sour, fishy stench, toss it. An ammonia odor is the single clearest warning sign of spoiled shrimp.
- Color: Fresh raw shrimp is translucent with a grayish or pinkish tint. If it has turned white, yellow, or developed black spots that spread across the shell, it is spoiling. Shrimp that has darkened or turned black in the fridge is past its prime and should be discarded.
- Texture: Fresh shrimp is firm and springy. If it feels slimy, mushy, gritty, or sticky, it is time to say goodbye.
- Shell condition: The shells should be intact and firm. Cracked, broken, or loose shells are a sign the shrimp has begun to break down.
These same spoilage signs apply to prawns, which are stored and judged exactly the same way as shrimp. If you notice any of these signs in shrimp or prawns, discard them to avoid the risk of food poisoning. Curious about other seafood? Read our guide on how long does white fish last in the fridge?.
Storing Raw Shrimp in the Fridge
How you package raw shrimp is as important as the temperature you store it at. Use airtight containers or resealable plastic bags to keep air and moisture out, both of which speed up spoilage. Set the container on a plate or tray to catch any drips and keep them off other food.
| Packaging Type | Description | Benefits |
|---|---|---|
| Original vacuum-sealed pack | The sealed pack the shrimp came in | Designed to maintain freshness; leave sealed until use |
| Airtight Container | Plastic or glass container with a tight seal | Keeps air and moisture out |
| Resealable Plastic Bag | Plastic bag with a sealable top | Easy to use and saves space |
| Vacuum Sealed Bag | Bag with air removed using a vacuum sealer | Extends shelf life by reducing air exposure |
Tips for Keeping Shrimp Fresh
Put these habits to work to get the full 1 to 2 days out of your raw shrimp:
- Keep it in the original packaging if sealed: If the shrimp is vacuum-sealed, leave it sealed. That packaging is built to hold freshness. Only transfer it to an airtight container once the pack has been opened.
- Store on a bed of ice: Set the container of shrimp on a bed of ice inside the fridge. The ice keeps the shrimp even colder than the fridge air and can extend freshness. Refresh the ice as it melts.
- Control the temperature: Hold shrimp at a steady 32°F to 38°F, and check your fridge with a thermometer. Ice packs around the container help if your fridge runs warm.
- First in, first out: Use older shrimp before newer batches, and label every container with the date it went in.
- Avoid cross-contamination: Store shrimp away from ready-to-eat foods like fruits and vegetables, and separate it from other raw proteins such as chicken and pork.
- Right-size the container: Use a clean, dry container that fits the amount of shrimp with as little empty air space as possible, and make sure the lid seals fully.
Freezing Raw Shrimp
Freezing raw shrimp is the best way to keep it on hand for whenever a seafood craving hits, and it stops spoilage in its tracks. Frozen raw shrimp stays good for 3 to 6 months.
- Clean and devein: Rinse the shrimp under cold water. Remove the shells, legs, and veins if you prefer, then pat them dry with paper towels.
- Portion and pack: Divide the shrimp into portions you will use in one go. Pack them into airtight freezer bags or vacuum-sealed bags, squeezing out as much air as possible to prevent freezer burn.
- Label and freeze: Label each bag with the freezing date and store at 0°F (-18°C) or lower.
| Storage Method | Duration |
|---|---|
| Freezer (0°F or lower) | 3 - 6 months |
Thawing and Refreezing Shrimp
Thawing shrimp correctly keeps it safe and preserves its texture. Use one of these three methods, and cook the shrimp promptly once it is thawed.
- Refrigerator thawing: Put the frozen shrimp in a covered bowl and leave it in the fridge. This slow thaw keeps the shrimp at a safe temperature the whole time.
- Cold water thawing: Need it faster? Seal the shrimp in a plastic bag and submerge it in cold water, changing the water every 30 minutes until thawed.
- Microwave thawing: Use the defrost setting, but watch closely. Microwaves thaw unevenly and can start cooking the shrimp if you leave it too long.
| Thawing Method | Time Required |
|---|---|
| Refrigerator Thawing | 12 - 24 hours |
| Cold Water Thawing | 1 - 2 hours |
| Microwave Thawing | 5 - 10 minutes |
Shrimp thawed in the refrigerator can be kept there for another 1 to 2 days before cooking. Refreezing is possible but comes with trade-offs:
- Quality degradation: Moisture lost during the first thaw can leave refrozen shrimp mushier once cooked.
- Safety rule: Only refreeze shrimp that was thawed in the refrigerator and never left at room temperature for more than two hours.
- Use it sooner: Refrozen shrimp is best used within one to two months.

Storing Cooked Shrimp
Cooked shrimp keeps in the fridge for 3 to 4 days. Store it in an airtight container or a resealable bag so it does not soak up other fridge odors, and give it a sniff and a look before eating.
| Storage Method | Shelf Life |
|---|---|
| Refrigerator (32-40°F) | 3 - 4 days |
| Freezer (0°F or lower) | Up to 3 months |
To freeze cooked shrimp, pack it in a freezer-safe bag or airtight container and squeeze out as much air as you can before sealing. Thaw it in the fridge overnight when you are ready to eat, and do not refreeze it once thawed, as that hurts the texture and flavor.

Cooking Raw Shrimp
Cooking raw shrimp is quick. Make sure it is fully thawed if it was frozen, rinse it under cold water, pat it dry, and season it. Shrimp is done when it turns pink and opaque and curls into a loose C shape. Do not overcook it, or it turns tough and rubbery.
| Cooking Method | Time | Heat / Temperature |
|---|---|---|
| Boiling | 2 - 3 minutes | Boiling water (212°F) |
| Grilling | 2 - 3 minutes per side | Medium-high (about 400°F) |
| Sautéing | 2 - 3 minutes per side | Medium-high |
| Baking | 6 - 8 minutes | 400°F (200°C) |
Raw shrimp is a blank canvas. A few dishes to try:
- Shrimp scampi: Sauté shrimp in garlic butter and serve over pasta.
- Shrimp tacos: Grill or sauté shrimp and serve in tortillas with cilantro, lime, and avocado.
- Shrimp stir-fry: Cook shrimp with vegetables and a savory sauce over rice or noodles.
- Shrimp cocktail: Boil shrimp and serve chilled with cocktail sauce.
- Shrimp salad: Toss cooked shrimp with greens, veggies, and a light dressing.
| Dish | Cooking Method | Approximate Time |
|---|---|---|
| Shrimp Scampi | Sautéing | 10 minutes |
| Shrimp Tacos | Grilling/Sautéing | 15 minutes |
| Shrimp Stir-Fry | Sautéing | 10 minutes |
| Shrimp Cocktail | Boiling | 5 minutes |

Frequently Asked Questions
Can you eat raw shrimp after 3 to 5 days in the fridge?
No. Raw shrimp is safe in the refrigerator for only 1 to 2 days. By day 3 it is at the edge of safety, and after 5 days it should be thrown out even if it looks and smells fine, because bacteria can reach unsafe levels before spoilage is obvious. If you cannot use raw shrimp within two days, freeze it.
How long can raw shrimp sit out at room temperature?
No more than two hours. Shrimp left at room temperature for longer than two hours should be discarded and should never be refrozen, as bacteria multiply quickly in the danger zone above 40°F.
Can thawed shrimp be refrigerated?
Yes. Shrimp thawed in the refrigerator can stay in the fridge for another 1 to 2 days before you cook it. Shrimp thawed in cold water or the microwave should be cooked right away.
Why did my shrimp turn black in the fridge?
Black spots or an overall darkening are a sign the shrimp is aging and breaking down. When black spots spread across the shell or the shrimp has clearly turned black in the fridge, treat it as spoiled and discard it rather than risk food poisoning.
Are prawns stored the same as shrimp?
Yes. Prawns follow the same rules as shrimp: 1 to 2 days raw in the fridge, 3 to 6 months frozen, and the same spoilage signs (ammonia smell, black spots, slimy or mushy texture, loose shells).
Can you eat shrimp after the expiration date?
Eating shrimp past its expiration date is not recommended. Shrimp is highly perishable and can become unsafe even before the date if it was not kept cold. Always check the date on the packaging, and when in doubt, throw it out.
Can you freeze raw shrimp for longer storage?
Yes. Freezing is the best way to extend the life of raw shrimp. Place it in an airtight container or freezer bag, remove as much air as possible to prevent freezer burn, label it with the date, and store at 0°F (-18°C) or below for 3 to 6 months.
| Storage Method | Duration |
|---|---|
| Refrigerator (Raw Shrimp) | 1 - 2 days |
| Freezer (Raw Shrimp) | 3 - 6 months |
