Can you eat seafood when pregnant?

Can you eat seafood when pregnant?


Eating shellfish in pregnancy is generally safe as long as it’s been cooked1. But if you’re a fan of raw oysters, you might have to choose an alternative dish from the menu. Raw shellfish carries a higher risk of food poisoning – and getting food poisoning in pregnancy can increase the risk of premature birth and infection2. Learn how to ensure shellfish is safe to eat in pregnancy.


Can you eat prawns when pregnant?

Yes, prawns are safe to eat during pregnancy if they’ve been thoroughly cooked.3 However, you should avoid eating raw prawns as they can contain bacteria which could give you food poisoning. Prawns turn from grey to pinky-red when they have been thoroughly cooked, so this is how you can tell whether or not they are safe to eat. Cold pre-cooked prawns are also fine to eat.3 For more information about choosing seafood that’s safe for you and your baby, see our table below.
