Smoked salmon is appreciated for its delicate flavour and tender texture, and is particularly popular during the festive season. However, eating it during pregnancy requires certain precautions. Health authorities advise pregnant women to avoid smoked fish eaten without further cooking because of the risk of listeriosis. This recommendation applies to all smoked salmon, regardless of its price, origin or production method. Why does this risk exist? What alternatives are available? And what should you do if you have already eaten smoked salmon?
Why is smoked salmon not recommended during pregnancy?
Smoked salmon can be contaminated with Listeria monocytogenes, a bacterium that causes listeriosis. This infection is particularly concerning because it can be transmitted through ready-to-eat foods, and the bacteria can multiply even at low temperatures, including in the refrigerator.
During pregnancy, listeriosis can have serious consequences for the unborn baby, even when the mother's symptoms are mild. For this reason, pregnant women are advised to avoid refrigerated smoked fish that is eaten without further heating. Keeping it in the refrigerator does not eliminate the risk.
Should cold-smoked salmon be avoided?
Yes. During pregnancy, it is best to avoid smoked salmon intended to be eaten as is, particularly cold-smoked salmon. Cold smoking gives the fish its distinctive flavour, but it does not cook it sufficiently to reliably eliminate Listeria bacteria.
The product's appearance and smell, vacuum packaging or an unexpired use-by date do not rule out contamination. Artisanal production or a premium product also offers no guarantee that Listeria is absent. This precaution applies regardless of the brand or flavour.
Can you eat cooked salmon during pregnancy?
Yes. Fish remains a valuable part of a balanced diet. Fresh or frozen salmon that is thoroughly cooked is a possible alternative to smoked salmon. If smoked salmon is used in a hot dish, it must be heated thoroughly throughout. Simply warming it slightly is not enough.
Some simple ideas include oven-baked salmon, salmon cooked in a parcel with vegetables, or salmon served with rice. Follow good food hygiene practices when preparing meals and prevent cross-contamination between raw and ready-to-eat foods.
Is artisanal or premium smoked salmon less risky?
Fish selection, production-process controls and maintaining the cold chain are important quality factors. However, they cannot guarantee that a ready-to-eat product is free from Listeria. The recommendations therefore apply to all smoked fish eaten without further cooking, including premium products.
Price, reputation and production methods do not replace the recommended precautions. It is important to distinguish culinary quality from a food's suitability for the specific health needs of pregnancy.
What should you do if you have already eaten smoked salmon?
Eating smoked salmon does not automatically mean that you have been infected. Try not to panic. If you develop a fever, experience unusual symptoms or have any concerns, contact your doctor or midwife. If possible, tell them which product you ate and when you ate it.
Listeriosis can take a long time to develop symptoms. If you are concerned, seek medical advice even if your symptoms are mild.
How can you enjoy salmon safely during pregnancy?
You do not need to avoid all fish. Health authorities generally recommend eating a varied selection of fish regularly, provided it is prepared properly. Choose thoroughly cooked salmon rather than cold-smoked salmon eaten without further heating.
Pay attention to food hygiene, proper storage and current official recommendations.
The key recommendation: avoid smoked salmon eaten as is during pregnancy, and choose properly cooked fish instead. If you are unsure, ask your doctor or midwife for advice.
