Can you eat fish when pregnant?

Summary

If you're a fish lover, there’s no need to miss out on your favourite dishes during your pregnancy. Fish provides protein, and oily fish in particular are a source of DHA – a type of Omega 3 LCPs (long chain polyunsaturated fatty acid) known to contribute to brain development. However, there are some types of fish that you should avoid and some that you should only eat every now and then.

Fish to avoid when pregnant

Shark, swordfish, ray and marlin are slow-growing fish which makes them more likely to have a higher mercury content. Mercury can affect your baby’s developing brain, so you’re advised to avoid these fish completely in pregnancy. Oysters and mussels should also be avoided as these may contain biotoxins which are not destroyed on cooking.

Fish to limit when pregnant

Tuna may contain higher levels of mercury than small fish, so try to limit your intake to:

• One fresh tuna steak (≤150g) per week, or
• Two 240g cans per week.

Safe fish during pregnancy

You can eat as much white fish (like cod, haddock, monkfish and plaice) and cooked shellfish as you like when you’re pregnant.
