How Long Raw Shrimp Lasts in the Refrigerator and How to Store It Safely

Raw shrimp stays fresh for one to two days in the refrigerator

Raw shrimp has a short window in the fridge because it spoils quickly once thawed or removed from the freezer. If you bought shrimp fresh from the counter (not frozen), it will keep for one to two days at 40°F or below. If you thawed frozen shrimp at home, use it within one to two days as well. The clock starts the moment shrimp reaches your fridge, so plan your meal accordingly.

The reason shrimp deteriorates so fast is its high moisture content and delicate muscle structure. Unlike chicken or beef, shrimp has almost no protective fat layer, and bacteria colonize the surface quickly once the shrimp is no longer frozen. Temperature control is your only real defense during this short window.

Key Takeaways

• Raw shrimp lasts one to two days in a refrigerator set to 40°F or colder, whether it was fresh or thawed.
• Store shrimp in the coldest part of your fridge—usually the back of the bottom shelf—in an airtight container or sealed bag to prevent drips onto other foods.
• Shrimp that smells like ammonia or has a slimy texture has begun to spoil and should be discarded.
• Freeze shrimp immediately if you cannot cook it within two days; frozen shrimp lasts three to four months at 0°F or below.
• Never thaw shrimp at room temperature; thaw it in the refrigerator overnight or under cold running water just before cooking.

Where to place shrimp in your refrigerator

The coldest spot in your fridge is almost always the back of the bottom shelf, away from the door. Doors open and close constantly, letting warm air in, so shrimp stored there will warm up repeatedly and spoil faster. The bottom shelf is coldest because cold air sinks, and the back stays coldest because it is farthest from the door's heat exchange.

Place shrimp in an airtight container or a sealed plastic bag. This does two things: it keeps the shrimp from drying out, and it prevents raw shrimp liquid from dripping onto vegetables or ready-to-eat foods below. If you bought shrimp in a foam tray wrapped in plastic, that wrapping is not airtight enough for storage longer than a few hours. Transfer it to a container with a tight seal.

Signs that raw shrimp has spoiled

Smell is the most reliable indicator. Fresh raw shrimp has a mild, briny ocean smell. Spoiled shrimp smells like ammonia or rotten eggs—a sharp, chemical odor that is unmistakable once you have encountered it. If you open the container and that smell hits you, discard the shrimp immediately.

Texture is the second signal. Fresh shrimp feels firm and slightly springy when you press it. As it spoils, the muscle fibers break down and the shrimp becomes slimy or mushy. The shell may also feel loose or separating from the meat. Any of these signs mean the shrimp is no longer safe to eat, even if it does not smell obviously bad yet.

Color changes are less reliable on their own because shrimp naturally varies in shade depending on the species and whether it has been cooked. However, if raw shrimp develops dark spots, black discoloration on the shell, or a dull gray appearance where it was once translucent, those are warning signs to pair with smell or texture checks.

Freezing shrimp extends storage to three to four months

If you know you will not cook the shrimp within two days, freeze it. Frozen shrimp at 0°F or below stays safe to eat for three to four months. Freezing halts bacterial growth completely, so the shrimp will not spoil during that time, though quality does gradually decline—the texture becomes slightly softer and the flavor fades.

Freeze shrimp in its original packaging if it is airtight, or transfer it to a freezer bag, pressing out as much air as possible before sealing. Shrimp frozen with excess air exposure will develop freezer burn—dry, discolored patches that affect texture and taste. Label the bag with the date so you know how long it has been frozen.

The right way to thaw frozen shrimp

Thaw shrimp in the refrigerator overnight, or thaw it under cold running water for five to ten minutes just before cooking. Both methods keep the shrimp at a safe temperature throughout thawing. Refrigerator thawing is slower but requires no attention; water thawing is faster and works well if you are cooking soon.

Never thaw shrimp at room temperature or in warm water. Room-temperature thawing allows bacteria to multiply rapidly in the outer layers while the center is still frozen. Once thawed this way, the shrimp becomes unsafe even if it looks and smells normal. The bacteria are already present; you just cannot see them yet.

Once shrimp is thawed, cook it the same day or store it in the fridge for up to one more day. Do not refreeze thawed shrimp unless you cook it first.

How to tell if your refrigerator is cold enough

Your fridge should maintain 40°F or below to keep shrimp safe. Most refrigerators have a temperature dial, but the actual temperature varies by location inside the fridge. The best way to know is to place an inexpensive refrigerator thermometer on the shelf where you store shrimp and check it after a few hours. Thermometers cost a few dollars and take the guesswork out of storage safety.

If your thermometer reads above 40°F, adjust the dial to a colder setting and recheck after several hours. If the fridge still will not reach 40°F, the cooling system may need service. In the meantime, shrimp will not stay safe for the full two days, so cook it sooner or freeze it immediately.

Cooked shrimp lasts longer than raw shrimp

If you cook the shrimp, it will keep for three to four days in the refrigerator. Cooking kills most of the bacteria present, so the main threat becomes recontamination from your hands, utensils, or other foods. Store cooked shrimp in an airtight container on the same cold shelf as you would raw shrimp, and keep it separate from raw foods to prevent cross-contamination.

Cooked shrimp also freezes well and lasts two to three months in the freezer. This is a practical strategy if you cook a batch and realize you will not eat it all within a few days.

Frequently Asked Questions

Can I store shrimp in the freezer compartment of my fridge instead of the main freezer?

Freezer compartments inside refrigerators typically stay around 0°F to 10°F, which is cold enough to freeze shrimp, but the temperature fluctuates more than a standalone freezer because the door opens frequently. Shrimp will freeze, but it may develop freezer burn faster. A standalone freezer at a steady 0°F is better for long-term storage, but the fridge freezer works if that is your only option.

What if I bought shrimp that was already thawed at the store?

Shrimp thawed at the store has already lost one day of its safe window. Treat it as if you thawed it at home: use it within one to two days, or freeze it immediately. Ask the fishmonger if the shrimp was thawed that morning or the day before; if it has been thawed for more than a day, cook it that evening or freeze it right away.

Is it safe to eat shrimp that smells a little fishy but not like ammonia?

A mild, briny fish smell is normal for fresh shrimp. If the smell is distinctly fishy—stronger than ocean water—but not ammonia, the shrimp is beginning to age but may still be safe if it is within the two-day window and feels firm. Use your judgment: if you are uncertain, discard it. The cost of shrimp is not worth the risk of foodborne illness.

Can I store shrimp in ice instead of a regular container?

Yes, and this is actually a good method if you have ice on hand. Place shrimp in a container and surround it with ice, keeping the shrimp as cold as possible. The ice will melt, so drain the water periodically or place the container on a tray to catch drips. This keeps shrimp colder than the fridge alone and can extend freshness slightly, but it is not a substitute for proper refrigeration—use it only as a temporary measure while you are preparing to cook.

Does vacuum-sealed shrimp last longer in the fridge?

Vacuum-sealed shrimp stays fresh slightly longer—sometimes two to three days instead of one to two—because the seal keeps oxygen away from the surface, slowing bacterial growth. However, do not rely on vacuum sealing to extend storage significantly. Open the seal and store the shrimp in a regular airtight container once you bring it home, or freeze it if you cannot cook it within two days.
