Can babies eat crab?

Last updated October 2026

Yes.

Babies ready for solids, usually around six months, can try a small amount of fully cooked crab. Crab is a crustacean shellfish allergen: introduce it separately from other new allergens. Check every portion for sharp shell or cartilage and finely shred the cooked meat into a moist familiar food.

When can babies eat crab?

The NHS permits fully cooked shellfish from around six months while advising against raw or lightly cooked shellfish. Introduce crab as a potential allergen one at a time, in a small first taste. Follow medical guidance for a diagnosed shellfish allergy.

FDA/EPA categorizes crab as a lower-mercury Best Choice. However, its fish portion sizes and weekly advice for children start at ages one to three years; do not infer an infant serving schedule or fixed weekly ounces.

How to serve crab safely

  1. Thoroughly cook fresh crab until the flesh is pearly or white and opaque, or follow directions for safely stored pre-cooked crab. After cooling, inspect and finely shred every flake, removing shell and cartilage. Offer a little with a soft, already tolerated food.

  2. Keep crab moist and manageable as skills develop. Check canned and prepared crab for sodium and additional allergens. Surimi (imitation crab) is often fish-based and its shellfish contents vary by product, so do not assume it introduces crab or is shellfish-free.

Safety considerations

  • Crab is a crustacean shellfish allergen; offer a small first taste separately from other new allergens when practical.

  • Do not offer raw or lightly cooked crab; cooked flesh should appear pearly or white and opaque.

  • Remove every sharp shell or cartilage fragment and finely shred the meat.

  • Do not use FDA/EPA serving-size advice for ages one to three as a six-month-old infant quota.

  • Read processed-food labels for sodium, fish, shellfish, wheat and egg.

  • Seek emergency care for throat swelling or breathing difficulty; always supervise seated meals.

Nutritional benefits for babies

  • Crab supplies protein.

  • It may contribute B12, zinc and selenium; amounts vary by species.

  • FDA/EPA lists crab among its lower-mercury seafood Best Choices.

  • Introducing an allergen does not require a fixed infant seafood quota.

  • Nutrition does not override correct cooking, allergen and choking precautions.
