Smoked salmon can be either cold-smoked or hot-smoked, and the safety details are different. Cold-smoked salmon is cured and smoked at low temperature, so it often has a silky raw-like texture. Hot-smoked salmon is cooked more fully and flakes like cooked fish. Refrigerated smoked salmon is still a perishable ready-to-eat food.
Cold-Smoked vs Hot-Smoked Salmon
| Type | Texture | How to treat it |
|---|---|---|
| Cold-smoked salmon | Silky, moist, thin-sliced, often labeled lox, nova, or cold smoked | Treat as ready-to-eat but higher caution, especially for people at higher risk from Listeria. |
| Hot-smoked salmon | Firm, opaque, flaky | Treat as cooked smoked fish, but still refrigerate and follow the package date. |
| Canned or shelf-stable smoked fish | Sealed shelf-stable package | Follow the package; refrigerate after opening if the label says to. |
Who Should Avoid Refrigerated Smoked Salmon?
CDC advises higher-risk people to choose shelf-stable smoked fish or smoked fish in a cooked dish instead of refrigerated cold-smoked fish. This matters most for pregnant people, older adults, and people with weakened immune systems because Listeria can grow at refrigerator temperatures and cold smoking does not reliably kill it.
Storage Checklist
- Keep refrigerated smoked salmon at 40 degrees F or below.
- Buy it before the date on the package and follow the package use-by or consume-within instructions.
- Keep it sealed until use, then rewrap leftovers tightly and return them to the refrigerator quickly.
- Do not leave smoked salmon out for more than 2 hours, or more than 1 hour above 90 degrees F.
- Discard it if the package is swollen, the fish smells sour or ammonia-like, the texture is unusually slimy, or you are unsure how long it was warm.
Can You Cook Smoked Salmon?
Yes. Cooking refrigerated smoked salmon in a hot dish can be a safer choice for higher-risk people, depending on the product and recipe. Add it to scrambled eggs, pasta, casseroles, fried rice, or chowder and heat the dish thoroughly. If a recipe serves the fish cold, use extra caution and follow the package directions closely.
FAQ
Is smoked salmon raw?
Cold-smoked salmon is often raw-like because it is smoked at low temperature after curing. Hot-smoked salmon is cooked more fully and has a firm, flaky texture.
Is refrigerated smoked salmon safe for pregnant people?
CDC recommends that pregnant people avoid refrigerated smoked seafood unless it is in a cooked dish, or choose canned or shelf-stable smoked seafood instead.
Does refrigeration kill Listeria in smoked salmon?
No. Refrigeration slows many germs, but CDC notes that refrigeration does not kill Listeria. Keep smoked salmon cold and follow the package date, but do not treat cold storage as a kill step.
How can you tell if smoked salmon is bad?
Discard smoked salmon if it smells sour or ammonia-like, feels unusually slimy, has mold, has a swollen package, or was left warm too long. When in doubt, throw it out.
