Can You Eat Cooked Salmon When Pregnant?
Written by Jordan Morley · Reviewed against NHS foods-to-avoid guidance · Last updated 28 October 2026
Yes — salmon that's already been cooked through (baked, grilled, pan-fried, poached) is one of the safest and healthiest choices in pregnancy, within the 2-portions-a-week oily-fish limit.
Why is cooked salmon a concern in pregnancy?
Cooked Salmon is an oily fish, and fish is a useful part of a pregnancy diet (Tommy's: fatty acids in fish may be important for brain activity, and fish provides iodine). However, the NHS says pollutants found in oily fish may build up in the body and could affect a baby's development in the womb, so it advises no more than 2 portions of oily fish a week. Within that limit, cooked salmon is a genuinely healthy choice.
You can also check the calorie content of cooked salmon alongside its safety information. Also check medication safety during pregnancy if you're managing any conditions.
The exception
The 2-portion weekly limit covers all oily fish combined — salmon, mackerel, sardines, trout, herring and pilchards — not 2 portions of each.
How your two portions are counted
The NHS fish page (last reviewed 26 June 2026) says girls and women who are pregnant, breastfeeding or planning a pregnancy should have no more than 2 portions of oily fish a week, and that a portion is around 140g cooked. Salmon is on the oily list. The confusion in most articles is what else counts, and what counts separately:
| Fish | Counts toward the 2-portion oily fish limit? | Source |
|---|---|---|
| Baked, grilled, poached or pan-fried salmon fillet | Yes: oily fish, about 140g cooked is one portion | NHS fish page |
| Tinned salmon | Yes: the NHS lists tinned salmon (not fresh) among oily fish with edible bones | NHS fish page |
| Trout, mackerel, sardines, herring, pilchards | Yes: counts in the same total, not 2 portions of each | NHS foods to avoid |
| Fresh or tinned tuna | No: 'do not count as oily fish'. It has its own limit of 4 cans or 2 steaks | NHS fish page; see tuna |
| Cod, haddock, pollock | No: the NHS calls these white fish, low in fat | NHS fish page |
| Shark, swordfish, marlin | Not allowed in pregnancy | NHS fish page |
Tommy's goes further than the cap and suggests at least two portions of fish a week, including one oily. Its page is undated, so check it against the NHS when in doubt.
UK limit or US 'eat more'?
Search results mix UK and US advice that sounds opposite. They answer different questions. The UK cap is about pollutants in oily fish; the FDA figure is about getting enough low-mercury fish. Our conversion of ounces to grams uses 28.35g to the ounce.
| Source | What it says | In grams (our conversion) |
|---|---|---|
| NHS (UK) | No more than 2 portions of oily fish a week; a portion is around 140g | Up to about 280g of oily fish a week |
| FDA (US, Feb 2024 seafood guide) | People who are pregnant or breastfeeding should consume at least 8 and up to 12 ounces of seafood per week | About 227g to 340g of seafood a week |
| Romper (US, June 2017) | Quotes Mayo Clinic: up to 12 ounces of fish a week, as three 4-ounce servings | About 340g a week |
They can both be true: the FDA range covers all low-mercury seafood, while the NHS cap covers oily fish like salmon. In the UK, stay within the NHS 2 portions of oily fish, and make up the rest with white fish.
What 'cooked through' means for salmon
The NHS says cooked fish is fine in pregnancy and tells you to avoid raw fish. The FDA seafood guide says most seafood should be cooked to an internal temperature of 145°F (about 63°C) and also tells pregnant women to avoid raw or undercooked fish. Colour is a poor guide (the FDA guide gives a number, not a colour, and we did not find a source that ties a particular pink shade to 145°F), so a probe thermometer in the thickest part of the fillet is the check that matches the rule.
Salmon dishes: which are fine, which are not
| Dish | In pregnancy | Why (source) |
|---|---|---|
| Salmon fillet, cooked through | Fine, counts as 1 oily portion | NHS: cooked fish is safe |
| Salmon fish cakes, fish pie, en croute, ready meals | Fine if cooked through and piping hot | Applies the NHS cooked-fish rule; check the pack's cooking instructions |
| Salmon sushi, sashimi, poke | Avoid | NHS: raw fish even if frozen |
| Smoked salmon on bagels, blinis, in salads | Avoid unless cooked until steaming hot | NHS; FSA/FSS notice. See smoked salmon |
| Gravlax or cured salmon | Avoid unless cooked until steaming hot | NHS names cold-smoked and cured fish |
| Salmon in a restaurant, medium or rare | Ask for it cooked through | NHS and FDA: avoid undercooked fish |
We found no explicit NHS line on hot-smoked salmon, which is why the smoked salmon page treats it separately.
Leftover cooked salmon
Cooked salmon needs chilling quickly and has its own fridge window; see how long cooked salmon lasts and can you reheat salmon. In pregnancy the NHS tells you to keep processed cold pre-cooked meats chilled and eat them before the use-by date, but we found no NHS line that treats home-cooked cold salmon differently from other leftovers.

Common questions
How much salmon can I eat when pregnant?
The NHS says no more than 2 portions of oily fish a week, where a portion is around 140g cooked. Salmon counts, and so does tinned salmon.
Does tinned salmon count as oily fish?
Yes. The NHS lists tinned salmon, though not fresh, among oily fish with edible bones, so it counts toward the 2-portion limit.
Can I eat salmon and tuna in the same week?
Yes. The NHS says fresh and canned tuna do not count as oily fish, so tuna has its own limit (4 cans or 2 steaks) alongside up to 2 portions of salmon or other oily fish.
Is slightly pink salmon safe when pregnant?
Colour alone does not answer it. The NHS says to avoid undercooked fish, and the FDA says most seafood should reach 145°F (about 63°C) inside, so check with a thermometer rather than by eye.
Is salmon safe in the first trimester?
Yes, when cooked through and within the 2-portion limit. The NHS does not change its fish advice by trimester.
Is the US advice to eat 8 to 12 ounces of fish a week different?
The FDA range covers all low-mercury seafood. The NHS 2-portion cap applies only to oily fish such as salmon, so the two can sit together.
Can I eat cooked salmon cold the next day?
We found no NHS rule that bans it. Keep it chilled and eat it within the time on our cooked salmon fridge page. Cold smoked or cured salmon is different and must be cooked until steaming hot.
