How long does salmon last in the fridge? It’s an important question because salmon is one of the most time-sensitive proteins you can refrigerate. Whether you’ve purchased fresh fillets, stored cooked leftovers, or picked up smoked salmon, understanding proper storage timelines is essential for maintaining both quality and food safety.
Unlike many meats, salmon contains delicate fats and high moisture that make it spoil faster if not handled properly. This guide breaks down realistic fridge timelines by type and gives you practical ways to avoid waste, or worse, foodborne illness.
How Long Does Salmon Last in the Fridge?
At refrigerator temperatures of 40°F (4°C) or below, salmon has a relatively short safe window. The exact answer to how long does salmon last in the fridge depends heavily on whether the fish is raw, cooked, or smoked.
A quick overview by type
Here is a practical at-home reference:
- Raw salmon: 1–2 days
- Cooked salmon: 3–4 days
- Smoked salmon (opened): about 5–7 days
- Smoked salmon (unopened): until the package date if kept sealed and cold
These timelines assume proper refrigeration and minimal temperature fluctuation.
Why is salmon more time-sensitive than many foods?
Salmon spoils faster than beef or chicken for several biological reasons:
- High unsaturated fat content
Salmon’s healthy omega-3 fats oxidize quickly, leading to rancid odors if stored too long.
- Moist, delicate muscle fibers
The soft texture allows bacteria to spread more easily than in dense meats.
- Natural enzyme activity
Even under refrigeration, enzymes continue breaking down fish tissue.
Because of these factors, understanding “How long does salmon last in the fridge” is especially important compared with many other proteins.
How Long Does Raw Salmon Last in the Fridge?
Raw fish has the narrowest safety margin. Under USDA and guidance, “How long does raw salmon last in the fridge” is typically 1 to 2 days maximum.
Recommended timeline
- Day 0–1: best quality
- Day 2: last recommended day
- Day 3+: discard
Even high-quality fish should not be stretched beyond this window unless frozen.
Storage tips for raw salmon
To maximize “How long does raw salmon last in the fridge”, follow these steps:
- Keep fish in its original airtight wrap or vacuum seal
- Store on the coldest bottom shelf
- Place on a tray to catch any liquid
- Refrigerate immediately after purchase
If you’re unsure whether you’ll cook it within two days, freezing is the safest move.
How Long Does Fresh Salmon Last in the Fridge?
Many shoppers use “fresh” to mean recently purchased, but the clock on salmon often starts before you buy it. Even so, how long does fresh salmon last in the fridge follows the same safety rules as raw fish.
Typical home guidance:
- Use within 1–2 days of purchase
- Keep consistently refrigerated
- Avoid repeated temperature changes
Signs that fresh salmon is declining
Watch closely for:
- Strong fishy or ammonia smell
- Dull or grayish color
- Sticky surface film
- Excess milky liquid
These indicate the fish is past its prime, even if still within the theoretical window for “How long does salmon last in the fridge”.

How Long Does Smoked Salmon Last in the Fridge?
Smoked salmon lasts longer because curing and smoking slow bacterial growth. Still, it is not shelf-stable after opening.
If you’re asking “How long does smoked salmon last in the fridge”, the answer depends on whether the package is opened.
Unopened smoked salmon
- Safe until the printed use-by date
- Must remain continuously refrigerated
- The vacuum seal must be intact
Opened smoked salmon
- Typically 5–7 days in the fridge
- Store tightly wrapped or in an airtight container
- Keep away from strong odors
Hot-smoked salmon behaves more like cooked fish. So if you are asking how long does cooked salmon last in the fridge, it should generally be eaten within 3–4 days once opened.
Planning Meals Around Salmon’s Short Life
Because salmon is highly perishable, smart planning is one of the easiest ways to avoid both food waste and safety risks. Many people focus only on how long does salmon last in the fridge, but the real advantage comes from timing your purchase, prep, and cooking around salmon’s short life span.
Here are practical strategies that make salmon easier — and safer — to manage at home:
Buy with timing in mind
Try to purchase salmon within 1–2 days of when you plan to cook it. Unlike beef or chicken, salmon doesn’t give you much buffer time. If your weekly menu changes often, consider buying frozen fillets instead so you can thaw only what you need.
Cook seafood earlier in the week
When doing weekly meal prep, schedule salmon meals for the first couple of days. Use longer-lasting proteins (like ground beef or pork) later in the week. This simple rotation helps you stay well within the safe window for how long does salmon last in the fridge.
Portion and freeze immediately if needed
If you buy a family pack but won’t cook it all, divide and freeze portions the same day. Freezing effectively pauses the clock on how long does salmon last in the fridge and preserves quality far better than waiting until day two.
Minimize transport time home
After purchasing, head home promptly, especially in warm weather. Even 30–60 minutes in a hot car can shorten the safe refrigerator life. If you run multiple errands, consider bringing an insulated bag or cooler.
Verify your refrigerator temperature
Many home fridges run warmer than the recommended ≤ 40°F (4°C). Using a simple fridge thermometer can help ensure you’re actually getting the full safe window for how long does salmon last in the fridge.
With these planning habits, you’re far less likely to face last-minute decisions about whether your salmon is still safe to cook or eat.
If You Eat Salmon That Has Turned
Seafood-related food poisoning can develop quickly after eating spoiled fish. Because salmon is highly perishable, exceeding the safe window for “How long does salmon last in the fridge” increases risk.
Seafood illness can appear quickly
Symptoms may begin within a few hours in some cases, though timing varies depending on the contaminant and the individual.
Common symptoms
People who eat spoiled salmon may experience:
- Nausea
- Vomiting
- Diarrhea
- Stomach cramps
- Fever or chills
Most mild cases resolve with rest and hydration. However, certain groups should be more cautious, including:
