When can babies eat mussels?
Mussels are a mollusc shellfish, a separate allergen from finned fish, and they are wonderfully rich in iron and B12. Freshness and food safety really matter here, so cook them thoroughly, discard any that stay shut, and chop them finely before introducing a small amount deliberately.
How to prepare mussels, by age
Are mussels safe? Choking & prep
Cook thoroughly and discard any mussels that stay shut after cooking. Buy fresh from a trusted source and cook the same day, since food safety really matters with shellfish. Introduce deliberately as its own shellfish allergen, separate from finned fish, one new food at a time.

Frequently asked questions
When can babies eat mussels?
From around 9 to 12 months. Cook them thoroughly, discard any that stay shut, chop finely, and introduce deliberately as a shellfish allergen.
Why discard mussels that stay shut?
A mussel that stays closed after cooking may not be good, and food safety matters most with shellfish. When in doubt, throw it out.
Are mussels really that good for iron?
Yes, mussels are one of the richer sources of iron and B12, which are both important in your baby’s second half of the first year.
Is fresh better than pre-cooked mussels?
Fresh cooked the same day is ideal. If you use pre-cooked or frozen, choose a trusted source, reheat until piping hot, and skip any packed in salty or heavy sauces.
