Can you eat smoked mackerel while pregnant?
Check firstYes, if it is Atlantic mackerel and hot-smoked. King mackerel is high in mercury and off the list entirely, and cold-smoked mackerel carries a Listeria risk until it is heated.
Why
Two separate checks apply. On mercury, the FDA puts Atlantic and Pacific mackerel in Best Choices at two to three servings a week, Spanish mackerel in Good Choices at one serving a week, and king mackerel in Choices to Avoid because of high mercury that can harm a developing nervous system. On bacteria, the smoked mackerel sold in supermarkets is usually hot-smoked, meaning cooked, and that is fine when it has been kept chilled. Cold-smoked or lightly cured mackerel is a refrigerated ready-to-eat seafood, and the FDA tells pregnant women to skip those unless they are cooked into a dish or shelf stable. Heating any smoked mackerel to steaming, 165F, clears the Listeria question.
Safer alternatives
- Hot-smoked Atlantic mackerel fillet, kept chilled and eaten within its date
- Smoked mackerel flaked into a hot pasta, risotto or kedgeree
- Canned mackerel in oil or tomato sauce
- Canned sardines for the same oily, smoky punch
- Fresh mackerel grilled to 145F

Frequently asked questions
Is all mackerel high in mercury?
No, and the difference is large. Atlantic and Pacific mackerel are low-mercury Best Choices, Spanish mackerel sits in the middle at one serving a week, and king mackerel is high enough in mercury that the FDA says to avoid it in pregnancy. Almost all smoked mackerel on sale is Atlantic.
Can I eat smoked mackerel pate?
Only if it is shelf stable or you bake it into something hot. Chilled fish pate is a ready-to-eat food where Listeria can grow during refrigerated storage, which is why the FDA puts it in the avoid group. Stirring smoked mackerel into a hot sauce yourself is a safe version.
Is smoked mackerel good for the baby?
Yes, it is one of the better oily fish choices. It is rich in omega-3 fats that support fetal brain and eye development, plus vitamin D and B12. Keep to two to three servings a week and go easy given the high salt.
