Why is prawns safe in pregnancy?
Cooked prawns — including the cold, pre-cooked prawns sold chilled in supermarkets — are safe to eat during pregnancy and a good source of protein. The NHS caution applies to raw or undercooked prawns (for example in some sushi or ceviche), which can carry bacteria and viruses.
You can also check the calorie content of prawns alongside its safety information. Also check medication safety during pregnancy if you're managing any conditions.
The exception
Avoid raw prawns. Cold cooked prawns should be in date and properly chilled; when in doubt, dishes where prawns are served piping hot are the safest choice.
