Can You Eat Raw Fish When Pregnant?
Written by Jordan Morley · Reviewed against NHS foods-to-avoid guidance · Last updated 28 October 2026
The NHS says to avoid raw fish in pregnancy, including sushi made with raw fish, even if the fish has been previously frozen. Raw shellfish and cold-smoked fish are also to be avoided unless cooked.
Why is raw fish a concern in pregnancy?
The NHS foods-to-avoid page (last reviewed June 2026) lists raw fish and raw shellfish, and “sushi made with raw fish (even if it has been previously frozen)”, under foods to avoid. Raw and cold-smoked fish may contain listeria, and raw shellfish can carry bacteria or toxins that make you seriously unwell. Older advice that freezing made raw fish acceptable is no longer in the NHS guidance, so do not rely on it.
You can also check the calorie content of raw fish alongside its safety information. Also check medication safety during pregnancy if you're managing any conditions.
The exception
Cooked fish is the simple safe option: the NHS says to cook fish and shellfish thoroughly, and sushi made with cooked fish or vegetables is fine. Mercury limits for tuna and the ban on shark, swordfish and marlin apply separately. Our sushi guide covers both angles.

Common questions
Can I eat raw fish in the first trimester?
The same advice applies throughout pregnancy: avoid raw fish and raw shellfish from the start.
Is a small amount of raw fish OK during pregnancy?
The NHS advice is to avoid raw fish rather than limit it, so even a small amount is something to skip.
I accidentally ate raw fish while pregnant — what should I do?
The risk from a single serving is low. Speak to your midwife or GP, or call NHS 111, if you develop stomach symptoms, a fever or flu-like symptoms.
Is cooked raw fish safe in pregnancy?
Cooked fish is always the simplest safe option in pregnancy.
