Raw fish keeps in the refrigerator for only 1 to 2 days when stored at or below 40°F (4°C). Cooked fish lasts a little longer, 3 to 4 days, while freezing extends storage to several months depending on the type. Because raw fish is one of the most perishable foods in your kitchen, storing it in the coldest part of the fridge, sealing it against air, and cooking or freezing it within that short window are what stand between a fresh fillet and foodborne illness.
How Long Can Raw Fish Stay in the Fridge?
When stored correctly, raw fish should be kept in the refrigerator for 1 to 2 days before it is cooked or discarded. Store the fish at a constant refrigerated temperature of 32°F to 40°F as soon as possible after purchasing. The type of fish makes little difference to how long it lasts raw, though fatty fish tends to lose quality first. The table below outlines the recommended storage duration for common types of raw fish:
| Type of Fish | Storage Time in Fridge (32°F to 40°F) |
|---|---|
| Lean fish (cod, flounder, tilapia) | 1-2 days |
| Fatty fish (salmon, trout) | 1-2 days |
| Shellfish (shrimp, scallops) | 1-2 days |
| Sushi/sashimi-grade fish | Follow store guidelines; eat as soon as possible |
| Cooked fish | 3-4 days |
The exact window narrows as your fridge warms toward the top of the safe range. Even a few degrees shortens the safe storage time, which is why a refrigerator thermometer is worth using:
| Refrigerator Temperature | Approximate Shelf Life |
|---|---|
| 32°F to 38°F (0°C to 3°C) | 1-2 days |
| 39°F to 40°F (4°C) | 1 day |
If you cannot cook the fish within this timeframe, freeze it for longer preservation rather than pushing past two days in the fridge.

How Long Can Raw Fish Be Left Out at Room Temperature?
Raw fish should not be left out at room temperature. Bacteria multiply rapidly in the "danger zone" between 40°F (4°C) and 140°F (60°C), and raw fish sitting on a counter warms into that range quickly. Refrigerate raw fish as soon as you get it home, and keep the total time it spends at room temperature to an absolute minimum, whether that is on the drive back from the market or while you prep it in the kitchen.
When transporting fish, keep it cold in an insulated cooler if the trip is long, and move it into the coldest part of the fridge the moment you arrive. If raw fish has been sitting out and you are unsure how long it was above 40°F, it is safer to discard it than to risk food poisoning. Refrigeration slows bacterial growth but never stops it entirely, so time out of the fridge always counts against the 1-to-2-day window.
Factors Affecting Raw Fish Shelf Life
Several factors determine how long your raw fish stays fresh in the refrigerator. Managing each one buys you the full 1-to-2-day window instead of losing the fish early:
- Initial freshness: The quality of the fish when you buy it sets the ceiling on its fridge life. Fish caught and refrigerated quickly after harvest lasts longer than fish that already spent time warm before chilling.
- Temperature: Store raw fish at or below 40°F (4°C), ideally 32°F to 38°F. Frequent temperature fluctuations from a door left open accelerate spoilage.
- Packaging: Airtight packaging minimizes exposure to air and bacteria. Vacuum-sealed or tightly wrapped fish lasts longest.
- Handling: Minimize the time the fish spends at room temperature and handle it with clean utensils and hands.
- Type of fish: Fatty fish such as salmon can spoil faster than lean fish because their higher fat content oxidizes over time.
Packaging in particular has a measurable effect. The table below shows roughly how storage method changes the safe window:
| Packaging Type | Approximate Shelf Life |
|---|---|
| Airtight container | 1-2 days |
| Plastic wrap or aluminum foil | 1 day |
| Uncovered | Less than 1 day |
One extra trick: placing the wrapped fish on a bed of ice inside the refrigerator holds it at a lower temperature than the surrounding air and keeps it fresh a little longer.

Optimal Temperature and Refrigeration Guidelines
When you bring raw fish home, it should be one of the first items you store. To preserve freshness, keep raw fish in the coldest part of the fridge, typically at the bottom or in a separate compartment designed for meats and seafood. If the fish is not already packaged to prevent leaks, place it in a sealed container or wrap it tightly to avoid drips and cross-contamination with other foods.
The optimal temperature for storing raw fish is at or below 40°F (4°C). This range slows the bacterial growth that thrives in the danger zone between 40°F (4°C) and 140°F (60°C). Use a refrigerator thermometer to confirm the setting, since a built-in thermostat is not always accurate.
| Storage Location | Recommended Temperature |
|---|---|
| Refrigerator (raw fish compartment) | ≤ 40°F (4°C) |
| Refrigerator (general) | ≤ 40°F (4°C) |
If you plan to eat the fish within a day or two, its original packaging may be sufficient, but for the longest hold add an extra layer such as a resealable bag to retain freshness and keep odors from spreading.

Safe Handling and Avoiding Cross-Contamination
Proper handling keeps raw fish safe from the market to the plate. Follow these steps once you get it home:
- Initial inspection: Ensure the fish is cool when purchased and has no unpleasant odors.
- Transportation: Keep the fish cold during transit, using an insulated cooler if necessary.
- Refrigeration: Once home, refrigerate the fish at 32°F to 38°F as soon as possible. If it will not be used within 1-2 days, freeze it.
- Storage location: Store raw fish on the lowest shelf to prevent juices from contaminating other foods.
- Packaging: Keep the fish in its original packaging or a sealed container to limit exposure to air.
- Separation: Store raw fish away from cooked and ready-to-eat foods.
Cross-contamination happens when bacteria transfer from one food to another, directly or by way of hands, utensils, cutting boards, or surfaces. To prevent it:
- Use separate utensils: Employ separate cutting boards and knives for raw fish and other foods.
- Wash hands: Wash thoroughly with soap and water before and after handling raw fish.
- Clean surfaces: Clean all surfaces, cutting boards, and utensils with hot, soapy water after preparing raw fish.
- Avoid dripping: Keep juices from raw fish from dripping onto other foods in the refrigerator.
- Consume promptly: Use raw fish soon after purchase to reduce the risk of spoilage and contamination.

Signs of Fresh vs. Spoiled Raw Fish
Assessing freshness by sight, smell, and touch is the most reliable way to decide whether raw fish is safe to eat. Fresh fish and spoiled fish differ across a few clear indicators:
| Indicator | Fresh Fish | Spoiled Fish |
|---|---|---|
| Smell | Mild, briny, like clean ocean water | Sour, ammonia-like, or overly fishy |
| Texture | Firm and springy; bounces back when pressed | Mushy, slimy, or sticky |
| Appearance | Vibrant color, shiny skin, translucent flesh | Dull or grayish color, milky liquid on the surface |
| Eyes (whole fish) | Clear, bright, slightly bulging | Cloudy and sunken |
| Gills (whole fish) | Bright red or pink | Dull, brown, or green |
If the fish shows any of the spoiled-side signs, err on the side of caution and throw it out. Use this quick reference for when to discard:
| Sign of Spoilage | Action |
|---|---|
| Strong, sour, or ammonia smell | Discard |
| Slimy or mushy texture | Discard |
| Dull, grayish, or milky color | Discard |
| Cloudy, sunken eyes | Discard |
| Brown or green gills | Discard |
If raw fish has been in the fridge longer than the recommended 1-2 days, or if anything seems off, dispose of it rather than take the risk.

Freezing and Thawing Raw Fish
Freezing prolongs the life of raw fish while preserving quality. Clean the fish, pat it dry, and place it in a freezer-safe bag or container with as much air removed as possible to prevent freezer burn, then label it with the date. Storage times depend on the fat content of the fish:
| Fish Type | Maximum Freezer Storage Time |
|---|---|
| Fatty fish (e.g., salmon, trout) | 2-3 months |
| Lean fish (e.g., cod, flounder, tilapia) | 6 months |
| Shellfish (e.g., shrimp, scallops) | 3-6 months |
The sooner you use frozen fish, the better the quality on thawing. For a species-specific example, see how long is tilapia good in the fridge.
Never thaw fish at room temperature. Transfer it from the freezer to the refrigerator and let it thaw gradually, or place the sealed bag in a bowl of cold water and change the water every 30 minutes. The table below shows typical thawing times:
| Thawing Method | Time Required |
|---|---|
| Refrigerator | 6-24 hours |
| Cold water (change every 30 minutes) | 1-3 hours |
Once thawed, cook the fish immediately and do not refreeze it without cooking first, as that compromises both safety and quality. Cook fish to an internal temperature of 145°F (63°C), measured at the thickest part with a food thermometer, whether you bake, grill, fry, or steam it.

Frequently Asked Questions
How long is raw fish good in the fridge?
Raw fish stays good in the refrigerator for 1 to 2 days when stored at or below 40°F (4°C). Beyond that window the risk of spoilage rises sharply, so cook or freeze it within two days. Fresh fish does not have a long shelf life, which is why buying it close to when you plan to cook it matters.
How long can raw fish be left out at room temperature?
Raw fish should not sit out at room temperature. It quickly enters the bacterial danger zone between 40°F (4°C) and 140°F (60°C), so refrigerate it right away and keep any time on the counter to a minimum. If you are unsure how long raw fish has been left out, discard it.
How long can uncooked fish stay in the fridge?
Uncooked (raw) fish keeps for the same 1 to 2 days as any raw fish. Store it in the coldest part of the fridge, sealed against air, and on the lowest shelf so its juices cannot drip onto other foods.
How long can tilapia stay in the fridge?
Tilapia is a lean fish, so raw tilapia lasts 1 to 2 days in the fridge at or below 40°F (4°C). In the freezer, lean fish like tilapia can be kept for up to 6 months.
How long can sashimi be kept in the fridge?
Sushi- and sashimi-grade fish should follow the store's guidelines and be eaten as soon as possible, ideally the same day it is purchased. Because it is eaten raw, hold it at or below 40°F and do not stretch it toward the general 2-day maximum.
How long does cooked fish last in the fridge?
Cooked fish lasts 3 to 4 days in the refrigerator when stored in an airtight container at or below 40°F (4°C), slightly longer than the 1 to 2 days for raw fish.
How can I tell if raw fish has gone bad?
Trust your senses. A sour, ammonia-like, or overly fishy smell, a slimy or mushy texture, dull or grayish color with milky liquid, cloudy sunken eyes, or brown gills all indicate the fish is spoiled and should be discarded.
