Can You Eat Smoked Salmon When Pregnant?
Updated June 2026 · based on NHS and official food-safety guidance
Cold-smoked salmon, lox and gravlax are not heat-cooked, so they can carry Listeria, a bacterium that is rare but dangerous in pregnancy and linked to miscarriage and stillbirth. The NHS says to avoid cold-smoked or cured fish unless it has been cooked until steaming hot, which kills any bacteria. In the US, the CDC and FDA say to skip refrigerated smoked seafood (labelled lox, nova-style, kippered or smoked) unless it is canned, shelf-stable, or cooked into a dish reaching 74C (165F).
Smoked salmon is one of those foods where the answer hinges on a single detail: was it cooked. Cold-smoked salmon and lox are cured but never heated, so they sit in the same risk bracket as deli meats for Listeria. Hot-smoked salmon, by contrast, is fully cooked. UK and US guidance line up closely here, and the good news is that smoked salmon is never completely off the table. Below you will find what the NHS, CDC and FDA actually say, broken down by type, so you can scan your plate and decide with confidence. For a specific product, the Muka app gives you a verdict in 3 seconds by barcode scan or photo.
Which types of smoked salmon are safe in pregnancy?
| Type | Verdict | Why |
|---|---|---|
| Cold-smoked salmon cooked steaming hot (in a quiche, pasta or bake) | Safe | Cooking smoked or cured fish until it is steaming hot all the way through kills Listeria. The NHS confirms this, and the CDC and FDA say smoked seafood is fine cooked into a dish that reaches 74C (165F). |
| Hot-smoked salmon (fully cooked, flaky, e.g. peppered or flaked hot-smoked) | Safe | Hot-smoked salmon is heat-treated during smoking, so it is already cooked. Keep it well chilled, check it is in date, and it is a good source of omega-3 and protein. If a pack does not clearly say hot-smoked, treat it as cold-smoked. |
| Canned or shelf-stable smoked salmon | Safe | The CDC and FDA list canned and shelf-stable smoked seafood (sealed, airtight packs that do not need refrigerating before opening) as safe choices, because processing destroys Listeria. |
| Cold-smoked salmon or lox, straight from the fridge (uncooked) | Avoid | Cold-smoking does not cook the fish, so Listeria can survive and even grow at fridge temperatures. The NHS advises avoiding cold-smoked or cured fish unless cooked steaming hot, and the CDC and FDA say the same for refrigerated smoked seafood. |
| Smoked salmon in sushi or on bagels (uncooked) | Avoid | Smoked salmon in sushi, on a bagel or in a cold sandwich is still raw cold-smoked fish. The NHS specifically names smoked salmon in sushi as one to avoid unless cooked steaming hot. |
| Gravlax or other cured (not smoked) salmon | Avoid | Cured salmon such as gravlax is salt-cured rather than cooked, so it carries the same Listeria risk as cold-smoked salmon. The NHS lists gravlax alongside smoked salmon to avoid unless cooked until steaming hot. |

What is the difference between cold-smoked and hot-smoked salmon?
Cold-smoked salmon is cured and smoked at a low temperature, so it stays silky and is not actually cooked. Hot-smoked salmon is smoked at a higher temperature that cooks the fish, leaving it firm and flaky. In pregnancy this matters: hot-smoked is already cooked and safe, while cold-smoked is best avoided unless heated steaming hot.
Is smoked salmon on a bagel safe in pregnancy?
A classic bagel with cold-smoked salmon or lox is not recommended, because the fish is uncooked and can carry Listeria. You can still enjoy it if the salmon is heated until steaming hot first, or swap in hot-smoked salmon, canned salmon, or fully cooked fresh salmon instead. Always check which type your pack contains.
Can I eat cooked smoked salmon while pregnant?
Yes. Cooking cold-smoked salmon until it is steaming hot all the way through kills Listeria and makes it safe. That means smoked salmon baked into a quiche, stirred through piping-hot pasta or cooked in a creamy bake is fine. The NHS, CDC and FDA all agree that thorough heating makes smoked and cured fish safe. Note that simply warming it through is not enough; it must be steaming hot.
How much smoked salmon can I eat in pregnancy?
Once it is cooked or hot-smoked and therefore safe, smoked salmon counts towards your oily fish. The NHS advises no more than two portions of oily fish a week in pregnancy because of low-level pollutants. A portion is around 140g, so a couple of servings a week of safe smoked salmon fits comfortably within that limit.
I ate cold-smoked salmon before I knew, should I worry?
Try not to panic. Listeria infection from smoked salmon is rare, and most people who eat a little cold-smoked salmon have no problems at all. Watch for symptoms like fever, aches, chills or flu-like feelings over the next few weeks, and contact your midwife or doctor if you feel unwell or are concerned.
