Cooked shrimp lasts 3–4 days in the fridge, 1–3 months in the freezer, and no more than 2 hours at room temperature.
USDA FoodKeeper has no separate entry for cooked shrimp. It is covered by “Cooked shellfish (all)” (cooked shellfish), so this page uses that entry’s storage times.

Check your cooked shrimp
Still inside the 2-hour limit. Put it in the fridge straight away, in a shallow container so it cools quickly.
Fine at normal room temperature. On a hot day above 32°C (90°F), 1 hour is already the limit, so refrigerate it immediately.
Two hours is the USDA cut-off. If it was warm, or you are not sure exactly how long, throw it out.
Past the 2-hour limit. Bacteria may have multiplied or produced toxins that reheating will not destroy.
Cooked shrimp left out overnight has spent many hours in the danger zone (4–60°C / 40–140°F). It may look fine, but it is not safe.
Room temperature means anything above 4°C (40°F). On hot days above 32°C (90°F), the limit is 1 hour.
Still safe, and at the end of its best-quality window. Use it in the next few weeks; texture and flavour fade after 1–3 months.
Food kept frozen solid stays safe indefinitely, but after 6 months expect freezer burn and dull flavour. Fine for soups, sauces and baking; trim dry grey patches.
Food kept frozen solid stays safe indefinitely, but after 9 months expect freezer burn and dull flavour. Fine for soups, sauces and baking; trim dry grey patches.
Assumes a freezer at -18°C (0°F) or colder. Frozen food stays safe; these verdicts are about quality.
About cooked shrimp
Cooked shrimp belongs to our seafood category. USDA FoodKeeper has no separate entry for cooked shrimp. It is covered by “Cooked shellfish (all)” (cooked shellfish), so this page uses that entry’s storage times. According to USDA FoodKeeper, it keeps 3–4 days in the fridge and 1–3 months in the freezer. Like all perishable food, it should not sit at room temperature for more than 2 hours. Where to keep it: ready-to-eat and cooked food goes on the upper shelves, above anything raw.
Cooked dishes and leftovers follow the same simple rules: cool them fast, refrigerate within two hours, and eat them within a few days. Cooking kills most bacteria, but some survive as heat-resistant spores, and new bacteria arrive from hands, utensils and air. How you cool and store the food after cooking matters more than how it was cooked.
Cooked shrimp storage times by method
| Method | Duration | Temperature | Container | Notes |
|---|---|---|---|---|
| Pantry / counter | 2 hours | 68–72°F | Airtight | 1 hour if above 90°F |
| Refrigerator | 3–4 days | ≤ 40°F / 4°C | Airtight | at or below 40°F (4°C) |
| Freezer | 1–3 months | 0°F / -18°C | Freezer bag or wrap | at 0°F; quality, not safety |

Cooked shrimp shelf life, answered
How long does cooked shrimp last in the fridge?
3–4 days at 4°C (40°F) or colder. Count from the day it was cooked, opened or bought.
How long does cooked shrimp last in the freezer?
1–3 months for best quality at -18°C (0°F). Frozen food stays safe indefinitely; after that, texture and flavour fade.
How long does cooked shrimp last at room temperature?
No more than 2 hours, or 1 hour above 32°C (90°F). Perishable food left out longer should be thrown away.
How long is cooked shrimp good for past the expiration date?
For perishable cooked shrimp, the storage clock matters more than the label: if it has been in the fridge longer than 3–4 days, discard it even before the printed date.
How can you tell if cooked shrimp is bad?
Sour, yeasty or 'off' instead of how it smelled when cooked. Slimy film, or liquid separating where it should not. Dull or darkened patches, or any discoloured spots.
How long can cooked shrimp sit out?
2 hours at room temperature, 1 hour on a hot day above 32°C (90°F). Overnight is always too long.
Signs cooked shrimp has gone bad
Smell
Sour, yeasty or 'off' instead of how it smelled when cooked.
Texture
Slimy film, or liquid separating where it should not.
Colour
Dull or darkened patches, or any discoloured spots.
Mould
Any fuzzy growth — discard the whole container, not just the spot.
Nothing ticked? Good sign. Still check how long it has been stored: the bacteria that cause food poisoning are invisible.
Any of these means it has gone bad. Throw it out — don't taste it to check.
Why cooked shrimp goes bad
Spores of bacteria such as Bacillus cereus and Clostridium perfringens survive cooking. When cooked food sits warm, the spores germinate and multiply quickly, and some produce toxins that reheating does not destroy. In the fridge they grow slowly, which is why cooked food has a window of a few days rather than weeks.
Common cooked shrimp storage mistakes
- Leaving a big pot to cool on the stove for hours instead of dividing it into shallow containers.
- Putting a deep, hot container straight into the fridge, which keeps the centre warm for hours.
- Reheating the same leftovers more than once.
- Tasting food to check whether it has gone off.
Can you freeze cooked shrimp?
- 1Step 1
Cool quickly: shallow containers, into the fridge or freezer within 2 hours.
- 2Step 2
Portion into freezer bags or airtight tubs, leave headspace for liquids, and label with the date.
- 3Step 3
Thaw in the fridge and reheat to 165°F (74°C) until steaming.
How to thaw cooked shrimp
In the fridge
Safest. About 24 hours per 2.3 kg (5 lb); small packs overnight. Raw meat and seafood then keep 1–2 more days.
In cold water
Seal it in a leak-proof bag, submerge, and change the water every 30 minutes. About 30 minutes per 0.5 kg (1 lb). Cook right away.
In the microwave
Use the defrost setting and cook immediately, because parts of the food may start to cook.
How to reheat cooked shrimp safely
Reheat to 74°C (165°F)
Check the thickest part with a food thermometer; it should be steaming hot all the way through.
Only once
Reheat just the portion you will eat. Each cool-and-reheat cycle gives bacteria another chance.
Cover and stir
In the microwave, cover the dish and stir halfway so there are no cold spots.
From the freezer
Thaw in the fridge first, or reheat straight from frozen and allow extra time.
Cooked shrimp left out overnight
Cooked shrimp left at room temperature for more than 2 hours (1 hour above 90°F / 32°C) should be thrown away. Bacteria multiply fastest between 40°F and 140°F, and reheating does not remove every toxin they make.
Bacteria multiply fastest between 4 °C and 60 °C (40–140 °F).
Best-by and use-by dates on cooked shrimp
Best-by and sell-by
FoodKeeper gives unopened cooked shrimp 3–4 days in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Past the date
For perishable cooked shrimp, the storage clock matters more than the label: if it has been in the fridge longer than 3–4 days, discard it even before the printed date.
How to store cooked shrimp
- Refrigerate within 2 hours of cooking (1 hour above 90°F) in shallow, airtight containers.
- Keep the fridge at or below 40°F (4°C); the door shelf is the warmest spot.
- Reheat leftovers to 165°F (74°C) and only reheat what you will eat.
How to pick fresh cooked shrimp
- For takeaway and deli food, get it home and into the fridge within two hours.
- Choose hot food that is steaming hot and cold food that feels cold.
- Check the prepared-on date for store-made dishes and count the fridge days from it.
Cooked shrimp: use it up in time
- Freeze portions on day one or two if you will not eat them in time.
- Turn leftovers into soups, fried rice, frittatas or wraps.
- Label containers with the date so you know exactly how long they have been in the fridge.
Cooked shrimp vs similar foods

- Cooked crab 3–4 days
- Cooked shellfish 3–4 days
- Crab legs 2–4 days
- Shrimp 1–3 days
- Cooked lobster tails 2–3 days

True or false? Cooked shrimp myths
- Correct!Not quite.
False. The bacteria that cause food poisoning rarely change the smell. Stick to the 3–4 days window and throw out anything older.
- Correct!Not quite.
False. Freezing pauses bacteria; it does not kill them. They become active again as the food thaws, so thaw in the fridge and cook or reheat properly.
- Correct!Not quite.
True. Quality holds for about 1–3 months at 0°F / -18°C. Frozen food stays safe indefinitely; only quality declines.
- Correct!Not quite.
False. The door warms up every time it opens. Ready-to-eat and cooked food goes on the upper shelves, above anything raw.
- Correct!Not quite.
False. Some bacteria make heat-stable toxins. Reheating kills bacteria but not those toxins, so food left out more than 2 hours should be thrown away.
