Can You Eat Shark When Pregnant?
Written by Jordan Morley · Reviewed against NHS foods-to-avoid guidance · Last updated 28 October 2026
No — the NHS says to avoid Shark completely during pregnancy because it contains high levels of mercury.
Why is shark a concern in pregnancy?
Shark is a large, long-lived predatory fish and contains more mercury than most other fish. Too much mercury can affect the development of your baby's nervous system, which is why the NHS advises avoiding Shark entirely while pregnant or trying for a baby.
You can also check the calorie content of shark alongside its safety information. Also check medication safety during pregnancy if you're managing any conditions.
The exception
Shark (sometimes labelled flake, or used in some specialty rolls) should be avoided whether raw, frozen or cooked — mercury isn't removed by any preparation method. See our sushi safety guide for the sushi fish that are genuinely safe.

Common questions
Can I eat shark in the first trimester?
Yes — the advice to avoid Shark applies to all of pregnancy, and mercury exposure in the first trimester is particularly worth avoiding as the nervous system is forming.
Is a small amount of shark OK during pregnancy?
The NHS advises avoiding Shark altogether during pregnancy rather than limiting it.
I accidentally ate shark while pregnant — what should I do?
A single portion is very unlikely to cause any harm — the concern is repeated exposure over time. Simply avoid it for the rest of your pregnancy and mention it to your midwife if you're worried.
Is cooked shark safe in pregnancy?
Cooking does not remove mercury, so Shark should be avoided during pregnancy whether cooked or not.
