How Long Shrimp Stays Fresh in Your Refrigerator

Raw shrimp lasts three to four days in the coldest part of your refrigerator

Raw shrimp keeps for three to four days when stored properly at 40°F or below. The clock starts the moment you bring it home, not the moment it was packaged. If you bought it from a grocery store counter, ask when it arrived that day — shrimp sold as "fresh" is often already a day or two old before you purchase it.

The key is temperature consistency. Store shrimp on the bottom shelf of your refrigerator, where it's coldest and away from ready-to-eat foods. If your refrigerator doesn't have a dedicated seafood drawer, place the shrimp package on a plate to catch any liquid that leaks, then position it as far back as possible on the lowest shelf.

Cooked shrimp lasts longer — three to four days as well, but the countdown begins after cooking. The difference is that cooking kills most bacteria, so cooked shrimp is more forgiving than raw. Store cooked shrimp in an airtight container to prevent it from absorbing odors from other foods.

Key Takeaways

• Raw shrimp stays good for three to four days when stored at 40°F or below on the bottom shelf of your refrigerator.
• Cooked shrimp also lasts three to four days after cooking, but must be stored in an airtight container to prevent odor absorption.
• Shrimp sold as "fresh" at the counter may already be one or two days old, so use it sooner rather than later.
• Freezing shrimp extends its life to six to eight months, making it a practical option if you won't use it within four days.

Signs that shrimp has gone bad

Shrimp that has spoiled will smell distinctly sour or ammonia-like — this is the most reliable warning sign. Fresh shrimp smells mildly briny or like the ocean; anything sharp or chemical means it's time to throw it out. Trust your nose; the smell is your body's way of detecting bacterial growth that makes shrimp unsafe to eat.

Look at the color and texture too. Raw shrimp should be translucent or grayish-white with a firm texture. If it looks mushy, has turned opaque white or pink, or feels slimy to the touch, bacteria has broken down the muscle fibers. Cooked shrimp should be pink and firm; if it's gray or falling apart, discard it.

How to store raw shrimp for maximum freshness

The moment you get shrimp home, place it in the coldest part of your refrigerator — the bottom shelf, toward the back. If the shrimp came in a sealed package, you can leave it sealed as long as the package isn't damaged. If it came loose from the seafood counter, transfer it to an airtight container or wrap it tightly in plastic wrap.

Pat the shrimp dry with paper towels before storing it. Excess moisture speeds up bacterial growth. If you're storing it for the full three to four days, place the container on a plate to catch any drips that might contaminate other foods below it.

Do not store shrimp in the door of your refrigerator, even if you have a seafood compartment there. Door shelves experience temperature fluctuations every time you open and close the door, which shortens shelf life. The back of the bottom shelf stays consistently cold.

Freezing shrimp extends storage to six to eight months

If you won't use shrimp within three to four days, freeze it. Frozen shrimp keeps for six to eight months at 0°F or below. Freezing stops bacterial growth completely, though it does change the texture slightly — thawed shrimp becomes softer than fresh shrimp, which is why it's better for dishes like shrimp pasta or stir-fries than for grilling or serving cold.

Freeze shrimp in its original packaging if it's airtight, or transfer it to a freezer bag with as much air removed as possible. Label the bag with the date you froze it so you know how long it's been stored. Thaw frozen shrimp in the refrigerator overnight, never at room temperature, to prevent bacterial growth during thawing.

Cooked shrimp storage and reheating

Cooked shrimp must cool to room temperature before you refrigerate it — putting hot food directly into the refrigerator raises the temperature of surrounding foods and creates condensation that promotes bacterial growth. Let cooked shrimp sit on the counter for no more than two hours, then transfer it to an airtight container.

Store cooked shrimp on the bottom shelf just like raw shrimp. It will last three to four days. When you're ready to eat it, you can eat it cold straight from the container, or reheat it gently in a skillet over low heat with a splash of water or butter. Avoid the microwave for reheating cooked shrimp — it tends to become rubbery.

Preventing cross-contamination with raw shrimp

Raw shrimp can harbor bacteria like Vibrio and Listeria that won't hurt you if the shrimp is cooked properly, but can cause serious illness if the bacteria spreads to ready-to-eat foods. Store raw shrimp below everything else on your bottom shelf, never above vegetables, cheese, or leftovers. Any liquid that drips from the shrimp package can contaminate food below it.

Use a separate cutting board for raw shrimp and wash your hands, the board, and any utensils with hot soapy water after handling it. Don't rinse raw shrimp under running water — this spreads bacteria around your sink. If you need to rinse it, do so in a bowl of cold water, then discard the water down the drain.

What to do if shrimp has been left out too long

Shrimp left at room temperature for more than two hours should be thrown away. Bacteria multiply rapidly between 40°F and 140°F, and shrimp's high protein content makes it a particularly good environment for growth. If shrimp has been sitting out for two to four hours and you're unsure of the exact time, the safest choice is to discard it.

If shrimp was left out overnight or longer, do not taste it to see if it's okay. Bacterial toxins can make you sick even if the shrimp smells and looks normal. When in doubt, throw it out — the cost of replacing shrimp is far less than the cost of food poisoning.

Frequently Asked Questions

Can I eat shrimp that smells a little fishy?

A mild ocean or briny smell is normal for fresh shrimp. A strong, sour, or ammonia-like smell means it's spoiled and unsafe to eat. If you're unsure, err on the side of caution — trust your nose.

Is it safe to refreeze shrimp that has thawed?

Shrimp that thawed in the refrigerator can be refrozen, but shrimp that thawed at room temperature should not be refrozen. Thawing at room temperature allows bacteria to multiply, and refreezing won't kill those bacteria. Always thaw shrimp in the refrigerator overnight.

Why does my shrimp smell like ammonia even though it's fresh?

Ammonia smell in fresh shrimp usually means it was stored too warm or too long before you bought it, even if the package date looks recent. Return it to the store if possible. Properly stored shrimp should smell briny, not chemical.

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

A freezer compartment inside your refrigerator is colder than the main fridge but usually not cold enough to truly freeze shrimp (it needs to reach 0°F). Use it only if you plan to cook the shrimp within one to two days. For longer storage, use a separate freezer.
