We sell smoked salmon for a living, so you might expect this page to be a hymn. It is not. Smoked salmon is a genuinely healthy food, but it has real drawbacks, and a couple of groups of people are better off avoiding it altogether. You deserve the full picture, so here it is, downsides first.
What are the disadvantages of smoked salmon?
The salt
This is the big one. Curing in salt is what transforms fresh salmon into smoked salmon, and you cannot have one without the other. When the UK’s Food Standards Agency sampled cold-smoked salmon at retail, it found between 2.2g and 3.5g of salt per 100g, which makes it one of the saltier items in your fridge, in the same league as cheese and cured meats.
In a normal 50g portion that works out at roughly 1g to 1.75g of salt, against a daily maximum of 6g. Manageable, but it adds up if you are grazing through a full packet on Stephen’s Day or stacking it on top of an already salty diet. If your blood pressure is on the high side, this is the disadvantage that matters most to you.
Listeria
Cold-smoked salmon is cured and smoked at low temperatures, so it is never cooked. That is the point of it, and for most healthy adults it poses no meaningful risk. But ready-to-eat chilled foods of this kind can occasionally carry Listeria monocytogenes, a bacterium that is harmless to most of us and dangerous to a few. This is why the pregnancy advice changed, and we deal with that fully below.
The price
Not a health drawback, but an honest one. Smoked salmon costs several times what fresh salmon does, for reasons we unpack in why is smoked salmon so expensive. The short version: you lose weight in the cure and the smoke, and the craft takes days. If budget is the concern, trimmings give you identical nutrition at a kinder price.
Smoke itself
Smoking food creates trace compounds called PAHs, which in large amounts are not good news. The quantities in commercially cold-smoked fish are small and regulated, and smoked salmon is something most people eat in 50g portions a few times a week, not by the kilo. It belongs on the list because you asked for the disadvantages, but it should sit at the bottom of it.
What it is not
Worth saying plainly: smoked salmon is not high in saturated fat, it is not high in sugar, it is not a processed meat in the World Health Organization sense, and it is not low in nutrition. The drawbacks above are the real ones. There is no hidden extra.
Who should not eat smoked salmon?
Pregnant women
Current Irish and UK food safety advice is that pregnant women should avoid ready-to-eat cold-smoked and cured fish, including smoked salmon, unless it has been cooked until steaming hot all the way through. The concern is listeria, which is rare but can be serious in pregnancy.
This advice is newer than many people realise, so you may hear “sure I ate it on all three of mine and they’re grand” from your mother. She is not wrong about her own experience, but the guidance has moved on. The happy loophole is cooking: smoked salmon baked into a fishcake, a tart or a pasta sauce that has been properly heated through is fine. If in doubt, ask your midwife or GP.
People with weakened immune systems
The same listeria logic applies to anyone whose immune system is compromised, whether through illness, chemotherapy or transplant medication, and older people are advised to weigh the same risk. For these groups the safe route is the same as in pregnancy: cooked thoroughly, or not at all.
People on a strict low-sodium diet
If you have been told to keep salt low for blood pressure, heart or kidney reasons, smoked salmon is one of the foods to ration carefully or set aside. The omega-3 benefits are real, but you can get them from fresh or plainly cooked salmon without the cure. That swap gives you everything good about the fish and nearly none of the salt.
Small children, in quantity
There is no rule against a toddler tasting smoked salmon, but small bodies have small salt budgets. A shred or two off your plate is fine. A child-sized portion several times a week is more salt than they need.
The honest summary
For a healthy adult, the disadvantages of smoked salmon come down to salt and money, both of which are handled by the same trick: treat it as a few beautiful slices, not a main ingredient by the fistful. For pregnant women and the immunocompromised, the listeria risk is real and the advice is clear. Cook it or skip it. Everyone else can read about the upside in is smoked salmon actually healthy with a clean conscience.
From the smokehouse: we would rather lose a sale than have you eat something that is wrong for you. If you are pregnant and craving the taste, smoked salmon cooked until steaming hot, in a fishcake, a tart or a pasta, gets you all the flavour inside the guidance.
