Why is mussels safe in pregnancy?
Cooked Mussels 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. Cooking destroys these hazards, so Mussels that are piping hot all the way through are fine.
You can also check the calorie content of mussels alongside its safety information. Also check medication safety during pregnancy if you're managing any conditions.
The exception
Avoid raw Mussels during pregnancy. Cold pre-cooked Mussels (for example from a deli counter) are also best avoided unless you reheat them until piping hot.
