Can Babies Eat Cobia? How to Cook and Serve

Cobia is best kept off your baby's plate. It is a large predatory fish that can carry high levels of mercury, which is especially risky for a developing brain. Choose a fish low in mercury like salmon, sardines, or croaker instead.

High in mercury

Cobia is a big, meaty offshore fish that is popular grilled or cut into steaks. It tastes great, but it is a large, long lived predator, and that is exactly the profile that concentrates mercury. It does not appear on the recommended lower mercury lists, and testing has found some cobia with very high mercury readings, so it is not a fish to give a baby.

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

6 to 9 monthsSkip cobia. Start fish with a low mercury option like salmon or sardines, cooked fully, deboned, and mashed or flaked soft.
9 to 12 monthsStill no cobia. Offer soft flakes of a low mercury fish such as trout or Atlantic croaker that your baby can pick up.
12 months+Keep cobia off the menu. Stick with low mercury fish a couple of times a week and save cobia for the occasional adult meal.

Is cobia safe? Choking & prep

Cobia is a large predatory fish, and mercury builds up as fish grow bigger and live longer. Testing has found cobia with mercury well above the levels considered safe, and it is not included on the FDA and EPA lists of fish recommended for young children.12 Because a baby's brain and nervous system are still developing, they are the most vulnerable to mercury, so cobia is a fish to skip entirely for now. If you want the omega-3 benefits of fish, reach for a low mercury option instead.

Nutrition

Cobia does offer protein and omega-3 fats, but for a baby those benefits are outweighed by its mercury risk. You can get the same omega-3s safely from low mercury fish like salmon, sardines, and trout.

Goes well with

Salmon · Sardines · Trout · Atlantic croaker · Pollock

Storage & freezing

Since this is not a fish to serve your baby, storage is mostly about your own portions. If you eat cobia yourself, keep it cold and cook it fully, and simply do not plate any for your baby.

Common questions

Can babies eat cobia?

It is best not to. Cobia is a large predatory fish that can carry high mercury, and it is not on the recommended fish lists for young children. Choose a low mercury fish instead.

Why is mercury a problem for babies?

Mercury builds up in big, long lived fish and can harm a developing brain and nervous system. Babies are the most sensitive, and cooking does not remove it, so the fix is choosing low mercury fish.

What fish should I give instead?

Salmon, sardines, trout, pollock, and Atlantic croaker are all low in mercury and great for babies. They give you the same omega-3 benefits without the risk.

I ate cobia while breastfeeding, should I worry?

An occasional adult portion is different from feeding it to a baby. Going forward, lean on low mercury fish, and if you have concerns talk to your pediatrician.
