Crab is a crustacean shellfish, which is a separate allergen from finned fish, so it counts as its own new introduction. Cook it thoroughly, check carefully for shell fragments, and chop it fine before offering a small amount deliberately.

Is crab safe? Choking & prep
Cook thoroughly and check carefully for sharp shell fragments. Introduce deliberately as its own shellfish allergen, separate from finned fish, one new food at a time. Note that imitation crab is usually white fish plus salt, so read labels and watch the salt.

Frequently asked questions
When can babies eat crab?
From around 9 to 12 months. Cook it thoroughly, check for shell, chop it fine, and introduce it deliberately as a shellfish allergen.
Is crab a different allergen from fish?
Yes. Crab is a crustacean shellfish, a separate top-9 allergen from finned fish like salmon, so introduce it on its own and watch for a reaction.
Can I give my baby imitation crab?
It is best skipped for babies. Imitation crab is usually white fish plus added salt and flavoring, so read the label and keep salt low in the first year.
What about shell fragments?
Even good crab meat can hide sharp bits of shell. Spread it out and pick through it carefully before chopping fine for your baby.
