When can babies have sea urchin?
Can babies have sea urchin?
Babies can have sea urchin from about 6 months only when it is fully cooked, such as stirred into a hot pasta sauce or scrambled egg. Sea urchin roe, or uni, is usually eaten raw in sushi, which is not safe for babies or young children. Cooked sea urchin is soft and creamy, but reactions to it are possible, so start small.
How to serve sea urchin by age
Shapes and textures change as your baby’s grasp and chewing grow.
6 months
Stir a small spoonful of fresh sea urchin into a hot sauce, risotto or soft scrambled egg and cook it until heated through, then blend or mash your baby's portion smooth. Offer it on a spoon.
7–8 months
Serve dishes cooked with sea urchin mashed with more texture, or offer soft pasta pieces or soft risotto clumps coated in the cooked sauce for your baby to grab. Keep serving only fully cooked sea urchin.
9–12 months
Offer pasta, rice or eggs cooked with sea urchin for self-feeding. Keep serving only fully cooked sea urchin.
12 months +
Toddlers can eat cooked sea urchin in pasta, rice and egg dishes. Raw uni and sushi are still best avoided for young children.
Why it’s good
Sea urchin roe gives protein, vitamin A, vitamin B12, zinc and some omega-3 fats. It is rich and creamy, so a little goes a long way. Sea urchin is an occasional special food rather than an everyday protein.
Safety notes
- Never serve raw sea urchin or uni sushi to babies and young children. Raw seafood can carry bacteria and parasites.
- Cook sea urchin until hot all the way through in a sauce or egg dish.
- Buy sea urchin from a trusted seafood seller, keep it cold and use it within a day or two. Spoiled uni smells sour or fishy and turns mushy.
- Do not let children handle live sea urchins. The spines can break off in the skin and cause painful wounds.
- Sea urchin is often served with soy sauce and seaweed, which can be very salty. Keep extras plain for babies.
A low-allergy food, still worth watching
Sea urchin is not a Top 9 allergen, but serious allergic reactions to sea urchin roe have been reported, including in people allergic to fish roe. Offer a small amount and watch closely for hives, vomiting, swelling or wheezing.
