How Long Fresh Shrimp Lasts in Your Refrigerator

Fresh shrimp stays safe to eat for one to two days in the refrigerator

Raw shrimp bought from the seafood counter or grocery store case will keep for one to two days at refrigerator temperature (40°F or below). The clock starts the moment you bring it home. If you bought it already thawed from a frozen state, use it that same day or the next day—thawed shrimp deteriorates faster than shrimp that was never frozen. Cooked shrimp lasts slightly longer, holding for three to four days under the same cold conditions.

The reason shrimp has such a short window is its high moisture content and delicate muscle structure. Unlike beef or chicken, shrimp lacks the protective outer layer that slows bacterial growth. Once the shrimp is exposed to air and warmth, bacteria begin multiplying rapidly. You cannot rely on appearance or smell alone to judge safety—harmful bacteria can grow without visible signs of spoilage.

Temperature matters more than anything else. Every degree above 40°F cuts your storage time in half. If your refrigerator runs at 45°F instead of 40°F, you lose a full day of safety. Check your fridge's actual temperature with an inexpensive thermometer; many people assume their refrigerator is cold enough when it is not.

Key Takeaways

• Raw shrimp keeps for one to two days in a refrigerator set to 40°F or colder, starting from the day you buy it.
• Thawed shrimp should be used the same day or next day, even if it came from a package labeled "previously frozen."
• Cooked shrimp lasts three to four days, but only if it was cooked fresh and refrigerated within two hours of cooking.
• Store shrimp in the coldest part of your refrigerator, usually the back of the bottom shelf, not the door where temperature fluctuates.
• Freezing shrimp immediately after purchase extends its life to three to six months and is the best option if you cannot cook it within two days.

How to store shrimp so it lasts the full two days

The container matters. Shrimp releases liquid as it sits, and that liquid accelerates spoilage if the shrimp sits in it. Transfer shrimp to a shallow container lined with paper towels, then cover loosely with plastic wrap or place it in a sealed container with a paper towel layer on the bottom. The paper towel absorbs excess moisture and keeps the shrimp from marinating in its own liquid.

Location in the refrigerator is equally important. Store shrimp on the lowest shelf, toward the back where cold air settles. Never store it on a shelf above raw meat or poultry—if the shrimp container leaks, it will not drip onto other foods. If your refrigerator has a dedicated seafood drawer or coldest zone, use that. The door is the warmest part of your fridge and unsuitable for shrimp.

Do not wash shrimp before storage. Water removes the protective coating and introduces bacteria. Rinse it only when you are ready to cook. If the shrimp came in a sealed package with liquid, you can leave it in that package as long as the seal is intact and you store it on the lowest shelf.

Signs that shrimp has gone bad

Smell is the most reliable indicator. Fresh raw shrimp has a mild ocean or briny smell. If it smells sour, ammonia-like, or strongly fishy, do not cook it. Cooked shrimp that smells off should also be discarded. Trust your nose—if you hesitate, throw it out.

Texture changes signal spoilage too. Fresh shrimp feels firm and slightly springy. If it feels mushy, slimy, or sticky to the touch, bacteria have begun breaking down the muscle fibers. Discoloration—graying, browning, or black spots—also indicates bacterial growth, though some discoloration can occur naturally during storage and does not always mean the shrimp is unsafe. When in doubt, combine the smell test with the texture test.

Do not rely on the "use by" date alone. That date assumes proper storage at 40°F from the moment the shrimp was packaged. If your refrigerator runs warmer or the shrimp sat at room temperature during transport, the actual safe window is shorter. The date is a guideline, not a may provide.

Freezing shrimp extends storage to months

If you cannot cook shrimp within two days, freeze it the same day you buy it. Frozen shrimp keeps for three to six months at 0°F or below. Freezing stops bacterial growth completely, though it does change texture slightly—frozen-then-thawed shrimp becomes softer than fresh shrimp cooked immediately.

Freeze shrimp in its original packaging if the package is airtight, or transfer it to a freezer bag with as much air removed as possible. Exposure to air causes freezer burn, which dries out the shrimp and makes it tough. Label the bag with the date so you know how long it has been frozen. Thaw frozen shrimp in the refrigerator overnight, never at room temperature—room-temperature thawing allows bacteria to multiply in the outer layers while the inside is still frozen.

Once thawed, treat it as fresh shrimp and cook it within one to two days. Do not refreeze thawed shrimp unless you cook it first.

Cooked shrimp storage and safety

Cooked shrimp must be refrigerated within two hours of cooking (one hour if the room temperature is above 90°F). Store it in a shallow, airtight container on the lowest shelf. Cooked shrimp lasts three to four days under these conditions. The shorter storage time compared to raw shrimp is misleading—cooked shrimp actually lasts longer than raw, but most people buy raw shrimp and cook it fresh, so the practical window is shorter.

Cooked shrimp can also be frozen. Spread cooked shrimp on a baking sheet, freeze it solid for two to three hours, then transfer it to a freezer bag. This method prevents the shrimp from clumping together. Frozen cooked shrimp keeps for two to three months. Thaw it in the refrigerator and eat it cold in salads or reheat it gently in a pan with a little butter.

What temperature your refrigerator should actually be

Your refrigerator should hold a steady 40°F or colder. Most people set the dial to a number (1 through 5, or similar) without knowing what temperature that produces. Buy a simple refrigerator thermometer—they cost a few dollars and take the guesswork out of storage safety. Place it on a shelf where you store shrimp and check it after 24 hours to see the actual temperature.

If your refrigerator runs warmer than 40°F, reduce shrimp storage time by half. At 45°F, shrimp is safe for only 12 to 24 hours. At 50°F or warmer, do not store raw shrimp at all—cook it immediately or freeze it. A refrigerator that cannot hold 40°F needs servicing or replacement.

Frequently Asked Questions

Can I eat shrimp that has been in the refrigerator for three days?

No. Raw shrimp is unsafe after two days, even if it looks and smells normal. Harmful bacteria can grow without visible signs. If you bought shrimp three days ago and have not cooked it, freeze it immediately or discard it. Cooked shrimp is safe for three to four days, but raw shrimp is not.

Is shrimp from the frozen section different from fresh shrimp?

Most "fresh" shrimp at the grocery store was frozen at sea and thawed for display. Once thawed, it should be used within one to two days, same as shrimp you thaw at home. Shrimp labeled "previously frozen" must be used the same day or next day. Buying frozen shrimp and thawing it yourself gives you more control over timing and often costs less.

What if I left shrimp on the counter for an hour?

Shrimp left at room temperature for one to two hours can still be cooked and eaten safely if it was fresh when you left it out. If it sat longer than two hours, or if the room was very warm, discard it. When in doubt, cook it immediately rather than refrigerating it again—cooking kills most bacteria, though not toxins some bacteria produce.

Does the color of raw shrimp tell you if it is fresh?

Color varies by species and diet, so it is not a reliable freshness indicator. Raw shrimp can be gray, white, pink, or brown depending on where it came from. Smell and texture are much better guides. If the shrimp smells fresh and feels firm, color does not matter.

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

No. The freezer section keeps food at 0°F or below, which stops bacterial growth but does not slow it—shrimp will freeze solid and become difficult to portion. If you want to extend storage beyond two days, transfer it to the main freezer compartment or a separate freezer. If you want to use it within two days, keep it in the coldest part of the main refrigerator, not the freezer.
