How Long Salmon Stays Fresh in Your Refrigerator

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

Raw salmon will keep for three to four days when stored properly in your refrigerator. The key is temperature: your fridge must stay at 40°F or below, and salmon must go into the coldest zone—usually the back of the bottom shelf, where cold air settles. If your refrigerator runs warmer than 40°F, cut that window to two days.

The clock starts the moment you bring salmon home, not when you open the package. If the fish has already been sitting in a grocery store case for a day or two, you have less time than the full three to four days. Ask the fishmonger when the salmon arrived, or check the "packed on" date if one is printed on the label.

Cooked salmon lasts longer—three to four days as well—but the storage method differs slightly. Let cooked salmon cool to room temperature before refrigerating (no more than two hours on the counter), then store it in an airtight container on a middle shelf where it won't drip onto other foods.

Key Takeaways

• Raw salmon keeps for three to four days at 40°F or below, stored in the coldest part of your refrigerator, usually the back of the bottom shelf.
• Cooked salmon also lasts three to four days, but must cool to room temperature first and should go in an airtight container to prevent odor transfer.
• Salmon stored above 40°F or in warmer zones of your fridge will spoil faster—plan for two days or less in those conditions.
• Freezing raw salmon extends its life to two to three months; frozen cooked salmon keeps for one to two months.

Why salmon spoils faster than other fish

Salmon's high fat content makes it more prone to oxidation and rancidity than leaner white fish. Those healthy omega-3 oils break down quickly once the fish is dead, especially at temperatures above 40°F. This is why salmon has a shorter refrigerator window than cod or halibut, which can last four to five days.

The moment salmon is cut or filleted, the exposed flesh begins to oxidize. Whole salmon steaks last slightly longer than fillets because less surface area is exposed to air. If you buy a whole side of salmon and cut it yourself, use the pieces within two days and freeze the rest.

How to store raw salmon so it lasts the full three to four days

Keep salmon in its original packaging if the seal is tight and the package sits flat. If the package is torn or leaking, transfer the salmon to a shallow glass or ceramic dish, cover it tightly with plastic wrap or aluminum foil, and place it on the bottom shelf of your refrigerator. Never store salmon directly on a shelf without a container—the drips will contaminate other foods and the salmon will dry out faster.

If you bought salmon vacuum-sealed, leave it sealed until you are ready to cook. Vacuum-sealed salmon lasts the full three to four days because the seal keeps oxygen out. Once you open the package, use the salmon within one day.

Do not rinse raw salmon before storing it. Water promotes bacterial growth and speeds spoilage. Rinse it only when you are ready to cook.

Signs that salmon has gone bad

Spoiled salmon smells distinctly sour or ammonia-like—much stronger than the normal ocean smell of fresh fish. If you open the package and the odor makes you hesitate, do not cook it. Trust your nose; it is a reliable indicator.

Look for changes in color and texture. Fresh salmon is firm and bright pink or orange. Spoiled salmon becomes dull, gray, or brown, and the flesh feels soft or mushy when you press it. Slime on the surface is another sign of bacterial growth. If you see any of these changes, throw the salmon away.

Do not taste salmon to check if it is safe. Harmful bacteria like Listeria and Salmonella can be present without changing the taste or smell noticeably.

Freezing salmon to extend its life

Freeze raw salmon within one to two days of purchase if you do not plan to cook it soon. Wrap the salmon tightly in plastic wrap, then place it in a freezer bag, pressing out as much air as possible. Label the bag with the date. Raw salmon frozen this way lasts two to three months.

Cooked salmon can also be frozen. Let it cool completely, wrap it in plastic wrap, place it in a freezer bag, and freeze. Frozen cooked salmon keeps for one to two months. Thaw frozen salmon in the refrigerator overnight, never at room temperature.

Freezing does not kill bacteria, but it stops bacterial growth. Thawed salmon must be cooked the same day it thaws, or refrigerated for no more than one day before cooking.

Storing smoked salmon and canned salmon

Smoked salmon (lox, nova, or kippered) is treated with salt and heat, which extends its life. Unopened smoked salmon lasts two to three weeks in the refrigerator. Once opened, use it within five to seven days. Store it in its original packaging or transfer it to an airtight container.

Canned salmon is shelf-stable and does not need refrigeration until opened. Once you open a can, transfer any unused salmon to an airtight glass or plastic container and refrigerate it. Opened canned salmon keeps for three to four days.

Organizing your refrigerator to keep salmon fresh longer

The coldest zone in most refrigerators is the back of the bottom shelf, where cold air from the freezer compartment settles. Store raw salmon here, away from the door. The door is the warmest part of your fridge because it opens and closes constantly, letting warm air in.

Keep salmon away from raw poultry and raw meat to prevent cross-contamination. If you must store them together, place salmon on a shelf above raw poultry so drips cannot fall onto it. Better yet, dedicate one shelf to seafood and another to raw meat.

Do not store salmon next to strong-smelling foods like onions or garlic. Salmon absorbs odors easily, and the reverse is also true—salmon's smell will transfer to other foods if they are stored too close.

Frequently Asked Questions

Can I eat salmon that has been in the fridge for five days?

No. Salmon kept at 40°F or below is safe for three to four days. After that, harmful bacteria like Listeria can multiply to unsafe levels, even if the salmon looks and smells normal. If you cannot cook it within four days, freeze it instead.

Does the type of salmon matter—wild versus farmed?

Both wild and farmed salmon have the same shelf life in the refrigerator. The difference is in flavor and fat content, not in how quickly they spoil. Store them the same way and use them within three to four days.

What if my refrigerator is warmer than 40°F?

Check your fridge temperature with a thermometer. If it runs above 40°F, reduce salmon storage to one to two days and freeze any you will not use immediately. A refrigerator that cannot hold 40°F or below should be serviced or replaced.

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

No. Freezer compartments are designed for long-term frozen storage at 0°F or below. Salmon stored there will freeze solid and develop ice crystals, which damages the texture. Use the main refrigerator for short-term storage and the freezer only for salmon you plan to keep for weeks.

Is it safe to cook salmon that smells a little fishy?

A mild ocean smell is normal for fresh salmon. A strong, sour, or ammonia-like smell means the salmon has spoiled and should not be cooked. When in doubt, throw it out—the cost of the salmon is far less than the cost of foodborne illness.
