Is Mussels safe in pregnancy?
Generally safe
Yes — thoroughly cooked mussels are safe.
What the evidence says
Mussels are safe in pregnancy provided they are thoroughly cooked. The shells should have opened fully during cooking; discard any that stay closed. Avoid raw or undercooked mussels.
Why this matters
Cooking destroys bacteria and viruses. Closed shells after cooking suggest the mussel was not alive before cooking, raising contamination risk.
