Fish that you CAN eat while pregnant:
Sushi, if the fish has been cooked all the way through (or, if it’s veggie sushi!)
Cooked shellfish (like mussels, lobster ((fancy!)) crab, prawns, scallops and clams.)
Fish that you should LIMIT your intake of:
No more than 2 portions of oily fish a week (like salmon, trout, mackerel or herring.)
No more than 2 tuna steaks or 4 medium-size cans of tuna per week.
Fish that you CAN’T eat while pregnant:
Cold-smoked or cured fish (like smoked salmon or gravlax.)
Why can’t I have certain kinds of fish when I’m pregnant?
There are a few different reasons why having certain kinds of fish when you’re pregnant can be a little bit risky. (And we really must stress, the risks are very small.)
Cold-smoked or cured fish have a tiny chance of carrying listeriosis (aka the reason why pasteurisation is your best friend.) However, cooking smoked or cured fish until it’s steaming hot will sort it out and ensure it’s 10000% safe.
You should limit your tuna intake because it’s chocked full of mercury. That’s fine usually, but too much can give you mercury poisoning. That goes for when you’re not pregnant too, by the way!
It could be a good idea to limit your oily fish intake too because of the pollutants you might find in them - like dioxins and polychlorinated biphenyls (No, we don’t know what they are. But they don’t sound great.)
And, last of all, the NHS recommends avoiding raw shellfish because they can have harmful bacteria, viruses or toxins in them. (The whole sweep!) These could possibly give you food poisoning, which, again, would just be pretty rubbish.
