Salmon is one of the most popular and nutritious types of seafood, but because it is highly perishable, proper storage is essential for maintaining freshness and food safety. Whether you have raw salmon from the grocery store or leftover cooked salmon from dinner, knowing how long salmon can last in the fridge can help prevent spoilage and reduce the risk of foodborne illness.
How Long Can Salmon Last in the Fridge?
Raw salmon typically lasts about 1 to 2 days in the fridge when stored properly at 40°F (4°C) or below, while cooked salmon can usually stay fresh for 3 to 4 days in an airtight container. To keep salmon fresh longer, store it in the coldest part of the refrigerator and wrap it tightly to reduce air exposure.
If you do not plan to eat it within a couple of days, freezing is the best option, as frozen salmon can maintain good quality for up to 2 to 3 months. Salmon that has developed a sour or ammonia-like smell, a slimy texture, or discoloration should be discarded.
Salmon Storage Guide
| Type of Salmon | Fridge Shelf Life |
| Raw salmon | 1–2 days |
| Cooked salmon | 3–4 days |
| Thawed salmon | 1–2 days after thawing |
| Smoked salmon | 1–2 weeks (unopened) |
| Defrosted salmon | cook immediately |
| Vacuum-sealed salmon | 1–2 weeks (unopened) |
How Long Does Fresh Salmon Last in the Fridge?
Fresh or raw salmon has a particularly short shelf life and can only last 1-2 days in the fridge before it goes bad. It is advisable to cook up fresh salmon as quickly as possible or store it in a freezer where it can last for weeks.
The general rule of thumb for keeping raw salmon in the fridge is 1 to 2 days maximum. 2 days is the safe baseline, but in some cases, salmon can last up to 3 days if it was exceptionally fresh or deep-chilled on ice.
While some vacuum-sealed retail packages show longer sell-by dates, home refrigerators fluctuate in temperature much more than commercial store displays. Leaving raw fish longer drastically increases the risk of spoilage and foodborne illness.
How to Store Raw Salmon in the Fridge
If not properly stored in the fridge, raw salmon can go bad even within a day. To ensure your raw salmon is properly stored in the fridge:
- Keep it in its original packaging or vacuum-sealed so it retains its freshness.
- If not in its original packaging, store it in a plastic bag or an airtight container.
- Place it on the bottom shelf of the fridge to avoid contaminating other foods with raw juices.
If you don’t plan to eat it within 1–2 days, freeze your raw salmon so it can last even longer.
Best Practices for Storing Raw Salmon
- Use the coldest spot in the fridge: Keep your raw fish all the way in the back of the fridge or inside the dedicated meat/crisper drawer, where temperatures remain lowest and most stable.
- Limit oxygen exposure: If the original packaging is opened, wrap the remaining portions tightly in plastic wrap with all air pushed out, then place it inside an airtight container
- Freeze immediately: If you buy a multi-pack and know you won't cook it within 48 hours, portion out what you need and put the rest straight into the freezer.
How Long Does Cooked Salmon Last in the Fridge?
Cooked salmon can last for 3–4 days in the fridge if you store it properly. To ensure that your salmon stays fresh and healthy for up to 4 days, take the following steps:
- Refrigerate it within 2 hours after cooking to prevent bacterial growth.
- Store it in an airtight container or wrap it tightly in plastic wrap or foil.
Cooked salmon stays safe and fresh in the fridge for 3 to 4 days max. This is the storage duration that most people agree with: the 3-day mark for peak quality. Beyond 4 days, the risk of foodborne illness increases significantly as harmful bacteria multiply, even under proper refrigeration.
Cooked Salmon Lasts Longer in the Freezer
If you don't plan to eat the cooked salmon within the recommended timeframe, consider freezing it for longer storage. In the freezer, cooked salmon can last for up to 2–3 months.
When you take it out of the fridge, make sure you reheat the cooked salmon to 165°F (74°C) before consuming. This is a crucial step for food safety.
Best Practices for Storing Cooked Salmon
- Storage: Wrap it tightly or place it in an airtight container. Placing a paper towel on the bottom of the container helps absorb excess moisture.
- Quality Check: If it smells sour, extremely fishy, or develops a slimy texture, throw it out immediately.
- Eat it Cold: Leftover salmon tastes much better cold on salads or sandwiches on days 2 and 3, rather than reheated, which can dry the fish out.
- Freezing: If you cannot eat it within 4 days, freeze it instead for up to 2 months.
How Long Does Thawed Salmon Last in the Fridge?
The best method for thawing fish is in the fridge, where the temperature is stable and safe. However, thawing salmon in the fridge does not significantly increase its lifespan.
Thawed salmon typically lasts about 1–2 days before cooking. To ensure your thawed salmon is safe for consumption, pay attention to the following tips:
- Don't refreeze thawed salmon unless it has been thawed in the fridge.
- If you thawed salmon using a cold water or microwave method, you must cook it immediately. Cooked salmon can then be stored for an additional 3–4 days.
How Long Does Defrosted Salmon Last in the Fridge?
If your salmon was defrosted in the fridge, it will be good for 1–2 days. However, if it was defrosted using quicker methods like cold water or microwave, you should cook it right away.
- Always defrost in the fridge for best results.
- Once defrosted, cook salmon within 1–2 days.
- Do not refreeze defrosted salmon unless it has been thawed in the fridge.
Smoked Salmon: How Long Does it Last in the Fridge?
In general, how long smoked salmon lasts in the fridge heavily depends on whether it is opened or not. Because it is salted and cured, it resists bacteria longer than fresh raw fish, but it will still spoil over time.
Smoked salmon significantly differs from fresh salmon and can last 1–2 weeks in the fridge as long as it is unopened. Once opened, it might begin to lose its flavor within 5–7 days. For the best flavor and also for your food safety, it is advisable to consume smoked salmon within 5-7 days.
In the freezer, it can last up to 2 months or more.
Tips for Storing Smoked Salmon in the Fridge
- Keep it sealed in its original packaging or in an airtight container.
- Refrigerate immediately and keep it below 40°F (4°C) to preserve its quality.
- Smoked salmon can also be frozen if you want to extend its shelf life for up to 2–3 months.
- Avoid cross-contamination: Any experienced cook you meet will seriously warn against pulling slices of smoked salmon out with your bare hands. Use a clean fork, tongs, or chopsticks to keep bacteria out of the container.
- Use the ziploc method: Transfer leftover slices into a tight ziplock bag and squeeze out all ambient air. This keeps the edges from drying out and turning leathery.
- Portion and freeze: If you buy large packs (like the bulk options at Costco or Sam's Club), separate the slices with wax paper or parchment paper. Place them in small freezer bags so you can easily thaw exactly what you need later.
How Long Does Vacuum-Sealed Salmon Last in the Fridge?
As long as it remains unopened,vacuum-sealed salmon can last 1–2 weeks in the fridge. However, once you’ve opened the packaging, treat it like fresh salmon and eat it within 1–2 days.
Tips for Storing Vacuum-Sealed Salmon in the Fridge
- Keep it in its original vacuum-sealed packaging until ready to use.
- After opening, transfer to an airtight container or plastic wrap and refrigerate promptly.
- If you won’t use it within the given timeframe, freeze it for up to 6 months.
Tips for Storing Salmon in the Fridge
Proper storage is the best way to keep salmon fresh, flavorful, and safe to eat.
- Whether the salmon is raw or cooked, it should always be refrigerated as soon as possible and kept at a temperature of 40°F (4°C) or lower.
- The coldest area of the fridge is usually the back of the bottom shelf, which is a better storage spot than the refrigerator door, where temperatures fluctuate more often.
- For raw salmon, remove any store packaging if it traps excess moisture, then pat the fish dry gently with paper towels before wrapping it tightly in plastic wrap, aluminum foil, or placing it in an airtight container.
- Limiting exposure to air helps slow bacterial growth and prevents the fish from drying out.
- For even better freshness, some people place the wrapped salmon on a tray or bowl filled with ice and replace the ice as it melts.
- Cooked salmon should be allowed to cool slightly before refrigeration, but it should not sit at room temperature for more than two hours.
- Store leftovers in a sealed airtight container to lock in moisture and prevent the salmon odor from affecting other foods in the refrigerator. Labeling the container with the storage date can also help you keep track of freshness.
- Keep salmon away from ready-to-eat foods such as fruits, salads, or bread to avoid cross-contamination.
- Always use clean utensils and surfaces when handling seafood.
- If you know you will not eat the salmon within 1 to 2 days for raw fish or 3 to 4 days for cooked salmon, freezing is the safest option.
- Properly wrapped salmon can maintain good quality in the freezer for around 2 to 3 months.
Signs That Salmon Has Gone Bad
Salmon that has spoiled often shows several noticeable warning signs. One of the most common is a strong, sour, fishy, or ammonia-like smell instead of the mild, fresh scent salmon normally has. The texture may also become slimy, sticky, or unusually soft to the touch.
Visually, spoiled salmon can appear dull, faded, or discolored, sometimes developing gray, brown, or milky spots on the surface. If the flesh looks dry around the edges or has an unnatural sheen, it may no longer be safe to eat.
How to Tell If Salmon is Bad: 4 Tell-Tale Signs
| Type | Fresh Salmon | Signs It is Bad |
| Smell | Mild, clean, or slightly like melon/ocean. | Strong “fishy” smell, sourness, or an ammonia odour. |
| Texture | Firm, smooth, and slightly moist | Slimy, mushy, and leaves indentations when poked |
| Appearance/ color | Bright, vibrant pink, or coral-red | Dull, greyish tinges or dark and discoloured patches. |
Safely Storing Smoked Salmon in the Fridge: How to Deal With the Risk of Listeria Bacteria
Reddit food safety groups r/foodsafety emphasize that Listeria bacteria can still multiply at cold refrigerator temperatures. High-risk groups, including pregnant individuals, should be exceptionally cautious with cold-smoked fish close to or past its date.
Storing Salmon in the Fridge: How to Handle the Risk of Botulism
Though it can be fixed, there is a hidden danger of botulism when storing vacuum-sealed packaged salmon in the fridge. Vacuum sealing makes salmon more susceptible to botulism. Clostridium botulinum bacteria thrive in anaerobic (zero-oxygen) environments and can grow even at cold refrigerator temperatures.
If you are thawing frozen salmon or storing raw salmon in your fridge, always cut open or completely remove it from the vacuum-sealed plastic to introduce oxygen and eliminate this specific risk.
Use the Bloat Test
If an unopened package of raw fish is puffing up like a balloon, gas has built up, and it should be tossed immediately. This is known as the bloat test, and it is a definite sign that the salmon has gone bad.
General Pro-Tips for Storing Salmon in the Fridge
If you cannot cook your salmon immediately, experienced Redditors suggest these tricks to maintain quality:
- The Ice Bed Trick: Keep your salmon in a tray resting over a bowl of ice in the fridge. Home fridges usually sit around 38°F–40°F, but fish keep best right at 32°F.
- Keep It Dry: Moisture breeds bacteria. Pat the filets completely dry with a paper towel and wrap them firmly before placing them in the coldest part of your fridge (usually the back).
- Freeze It Immediately: If you buy a multi-pack and know you won't eat it all by tomorrow, freeze the extra portions the day you bring them home instead of waiting for them to sit in the fridge.

FAQs
How long does raw salmon last in the fridge after defrosting?
After defrosting, raw salmon can usually last in the fridge for about 1 to 2 days if it is kept properly refrigerated at 40°F (4°C) or below. The safest way to thaw salmon is in the refrigerator, as this keeps the fish at a safe temperature during the defrosting process. Once thawed, the salmon should be cooked within a couple of days for the best quality and safety. If the salmon was thawed using cold water or a microwave, it should be cooked immediately rather than stored again in the fridge.
How long does salmon last in the freezer?
Salmon can last in the freezer for quite a long time, but its quality depends on how it is packaged and stored. Raw salmon can typically be frozen for up to 2 to 3 months while maintaining the best flavor and texture, though it may remain safe to eat for up to 6 months or longer if kept consistently frozen at 0°F (-18°C). Cooked salmon also freezes well and generally lasts about 2 to 3 months for best quality.
How long does cooked salmon last outside the fridge?
Cooked salmon should not be left outside the fridge for more than 2 hours at room temperature (or 1 hour if the temperature is above 90°F / 32°C). After this time, bacteria can grow quickly, making it unsafe to eat even if it still looks and smells fine.
Can raw salmon last 4 days in the fridge?
No, raw salmon generally should not last 4 days in the fridge. Fresh raw salmon is typically safe for only 1 to 2 days when stored properly at or below 40°F (4°C). After that, the risk of bacterial growth increases significantly, even if it still looks or smells okay.
Can I cook salmon that has been in the fridge for 5 days?
In most cases, no, it’s not recommended to cook and eat raw salmon that has been in the fridge for 5 days. Fresh raw salmon is typically safe for only 1–2 days in the refrigerator, even if it looks and smells fine. After 5 days, the risk of bacterial growth and spoilage is high, and cooking it won’t always make it safe because some bacteria can produce toxins that aren’t destroyed by heat.
How to tell if salmon has gone bad?
You can usually tell salmon has gone bad by checking its smell, texture, and appearance.
Fresh salmon should smell mild and slightly ocean-like. If it has gone bad, it often develops a strong sour, fishy, or ammonia-like odor, which is one of the clearest warning signs. The texture is another key indicator—spoiled salmon may feel slimy, sticky, or overly soft instead of firm and moist. Visually, bad salmon can look dull, grayish, or discolored, and may even develop milky or dark spots on the surface.
If you notice any mold, unusual liquid buildup, or a noticeably off smell, it’s best to discard it immediately. When in doubt, it’s safer not to eat it, since spoiled fish can cause foodborne illness even if it looks only slightly off.
