Why is crab safe in pregnancy?
Cooked Crab are safe during pregnancy and a good source of protein and minerals. The caution applies to raw or undercooked shellfish, which can contain harmful bacteria, viruses or toxins that could cause food poisoning. The NHS says cooked shellfish is safe, so Crab that are piping hot all the way through are fine.
You can also check the calorie content of crab alongside its safety information. Also check medication safety during pregnancy if you're managing any conditions.
The exception
Make sure crab served cold (including in sushi rolls) is fully cooked, not raw — crab is low in mercury, so it's one of the better seafood picks for a sushi order; see our sushi safety guide for the full picture.
