Can you eat mussels while pregnant?
SafeYes, mussels are safe during pregnancy when cooked until the shells open and the meat is hot through. Raw or undercooked shellfish is the version to skip.
Why
Mussels are low-mercury shellfish and a strong source of iron, B12 and protein, all pregnancy priorities. Steaming takes them to doneness in minutes, and a properly cooked pot of mussels meets the standard the NHS sets when it advises pregnant women to avoid raw shellfish but enjoy cooked. Order them fully steamed, skip any that did not open, and eat them hot rather than after the bowl has gone cold.
Safer alternatives
- Cooked clams
- Cooked shrimp
- Cooked scallops

Frequently asked questions
Are moules frites safe while pregnant?
Yes: the mussels are steamed until they open and served hot, and the fries are fried. The classic white wine broth loses most of its alcohol during the boil, and the amount clinging to mussels is trivial; a tomato or cream broth works if you prefer none.
Should I avoid mussels that have not opened?
Yes, set them aside, that is standard practice for everyone. An unopened shell means the mussel may not have cooked properly, which matters a little more than usual during pregnancy.
Are frozen or half-shell mussels from the store okay?
Yes, cook them until steaming hot all the way through. Frozen half-shell mussels are usually pre-cooked, so treat them like ready-to-eat seafood: real heat before serving, not just thawing.
