How Long Does Raw Salmon Last in the Fridge?
Raw salmon stays safe for 1–2 days refrigerated — here's how to tell before it's too late.
Raw salmon lasts 1–2 days in the refrigerator. Freeze it if you won't cook it within 2 days.
Raw salmon is one of the most perishable proteins in the kitchen. Whether you picked up a fresh fillet at the fish counter or thawed a portion from the freezer, the refrigerator clock starts ticking immediately. Raw salmon stays safe for just 1–2 days at or below 40 °F (4 °C), according to USDA and FDA guidance. Beyond that window, bacterial growth accelerates fast enough to cause foodborne illness even if the fish looks mostly fine. This guide walks through every stage — from peak-fresh to toss-it — so you can make a confident, safe call every time.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
The full timeline
Day 1 (Peak Fresh)
0–24 hours
- Flesh is vivid pink-orange with a moist, translucent sheen
- Smell is clean, faintly oceanic — not fishy
- Texture is firm and springs back when pressed
- Any skin is tight and metallic-bright
- Cook now for best flavor and texture
- Wrap tightly in plastic or butcher paper and refrigerate at 32–40 °F
- Freeze in an airtight bag if cooking within 2–3 months
Day 2 (Use Today)
24–48 hours
- Color has shifted slightly toward a duller salmon-pink
- Mild fishy scent is detectable but not sharp or sour
- Flesh still firm but less springy than day one
- Surface moisture looks slightly less glossy
- Cook immediately — bake, pan-sear, or poach
- Freeze right now if plans changed; quality will be decent
Day 3 (Caution Zone)
48–72 hours
- Noticeable fishy or faintly sour odor when package is opened
- Flesh color turning grayish or brownish at the edges
- Surface feels slightly tacky or slimy to the touch
- Liquid pooling in the package may look cloudy or milky
- Discard if any sour, ammonia, or sharp odor is present
- Discard if surface sliminess is noticeable
- Do not serve raw or as sushi/sashimi at this stage
Day 4 (Unsafe)
72+ hours
- Strong, sharp, or sour fishy odor — unmistakable spoilage
- Flesh is gray, brown, or opaque throughout
- Surface is visibly slimy with sticky or stringy texture
- Possible discoloration or off-color liquid in packaging
- Toss immediately — do not taste, cook, or repurpose
- Seal in a bag before discarding to contain odor
Common questions
Can I eat raw salmon after 2 days in the fridge?
The USDA and FDA both cap raw fish at 1–2 days refrigerated. By day 3, bacterial load can be high enough to cause illness even if the salmon looks mostly okay. Sage's Verdict: if it's past 48 hours, cook it immediately or discard — never serve it raw.
How long does raw salmon last in the freezer?
Raw salmon keeps well frozen for 2–3 months for best quality. It remains technically safe beyond that but texture and flavor degrade noticeably. Vacuum-sealed fillets hold up better than loosely wrapped ones.
Can I refreeze raw salmon that has been thawed in the fridge?
Yes, if it was thawed in the refrigerator and is still within the 1–2 day window, refreezing is safe. Expect some texture loss on the second thaw. Never refreeze salmon thawed at room temperature.
What does bad raw salmon smell like?
Fresh salmon smells faintly oceanic and clean. Spoiled salmon smells sharply fishy, sour, or faintly of ammonia. If the odor makes you pull back, trust that reaction — it's a reliable spoilage signal.
Is it safe to eat raw salmon (sushi-grade) from the grocery store?
Only if it is labeled sushi-grade or sashimi-grade and is within day 1 of purchase. Standard grocery fillets are not processed for raw consumption. Sage's Verdict: when in doubt, cook it.
How should I store raw salmon in the fridge to maximize freshness?
Place the fillet on a plate or tray, cover tightly with plastic wrap or keep in its original sealed packaging, and store on the coldest shelf (usually the bottom). Keep your fridge at or below 40 °F (4 °C). Avoid storing near strong-smelling foods.
Raw salmon is worth the care — just respect the 1–2 day rule, keep it cold, and when the smell says no, the answer is always toss.
