Can Babies Eat Manila Clam? How to Cook and Serve

Also known as Japanese littleneck.

Manila clams are small, sweet clams, also called Japanese littlenecks. They can be offered from around 6 months, steamed until the shells open and a few minutes more, then minced, with finely chopped pieces from about 9 months. They are a mollusk, not one of the nine major allergens, but they can still cause a reaction, so introduce them on their own. They must never be served raw, and their chewy texture is a choking risk, but they bring a lot of vitamin B12 and are low in mercury.

Manila clams are small, sweet clams, also called Japanese littlenecks, the kind you find steamed in pasta or broth. They are a mollusk shellfish and a rich source of vitamin B12. Steamed until they open, then a few minutes more, and chopped small, they can be part of a meal your baby shares, once you have introduced them as an allergen.

Prep School: how to prepare manila clam for baby-led weaning (BLW) and purées

🍴 Baby-led weaning

6 monthsClams should reach 165°F (74°C);⁹ a thermometer is hard to use in a shell, so steam them until they open, then 4 to 9 minutes more, discard any that stay shut,⁶⁷ and remove the meat. Mince it finely and stir it into a scoopable food like congee, mashed potato, or pasta, checking for grit or shell as you go. The chewy texture means it is not a whole finger food yet.

9 monthsFinely chop the cooked clam meat and stir it into pasta, rice, or another soft dish. The chewy texture means it is not a whole finger food yet.

12 months+Offer small, finely chopped pieces of cooked clam once your toddler chews confidently, still checking for shell fragments and keeping the dish low salt.

Is manila clam safe? Choking & prep

Clams are a shellfish and can cause allergic reactions, and like other allergenic foods they can go in from around 6 months,⁴ so start with a small amount on its own and watch for a reaction before working them into a full meal.¹ Shellfish should reach 165°F (74°C);⁹ a thermometer is hard to use in a shell, so cook manila clams until the shells open, then keep going: boil them 3 to 5 minutes more, or steam them 4 to 9 minutes more, and throw out any that stay shut.⁶⁷ Never serve them raw, because raw or undercooked clams can carry harmful bacteria, such as Vibrio, and viruses.²⁶ Once cooked, clam meat is chewy and slippery, so chop it finely and check for grit or shell fragments.³ Clams are low in mercury and on the FDA Best Choices list, though like other shellfish they can carry a little cadmium, so keep variety in the diet.¹

Nutrition

Clams are a nutrition standout for babies in vitamin B12: USDA data puts cooked clams at about 99 micrograms per 100 g. They also bring useful iron, about 2.8 mg per 100 g, which babies need as their newborn iron stores run down, plus zinc and protein.⁸ They are low in mercury too. Like other shellfish they can carry small amounts of cadmium, so enjoy them as part of a varied diet rather than every day.

Storage & freezing

Keep live clams cold in the fridge in an open container covered with a damp cloth, never sealed airtight or sitting in fresh water, and cook them within a day or two. Discard any that are cracked or that stay open when tapped. Cooked clam meat keeps 1 day sealed in the fridge.⁵ Reheat until hot and cool before serving.

Common questions

How do I know the clams are cooked?

Cook them until the shells open, then keep boiling 3 to 5 minutes more or steaming 4 to 9 minutes more. Throw away any clam that stays shut, since it may not be safe.⁶⁷

Are canned clams okay for my baby?

Yes, in a pinch. Choose ones with no added salt or rinse them, then chop the meat finely and check for any bits of shell. Fresh steamed clams are lower in salt.

How do I get rid of the sand and grit?

Soak the live clams in cold salted water for 20 to 30 minutes so they spit out sand, then scrub the shells before cooking. Chop the cooked meat and feel for any grit before serving.
