Yes, in moderation — canned tuna is fine from 6 months, but mercury makes it an occasional fish, not an everyday one. Rotate with lower-mercury fish.

Why

Tuna sits in an awkward middle: affordable, protein-rich and widely available, but higher up the food chain than salmon or sardines, so mercury accumulates in it more. Guidance for young children is built around variety and moderation rather than prohibition. The practical answer is rotation — tuna sometimes, lower-mercury fish most days.

How to serve it safely

Choose canned light tuna over albacore where you can, packed in water with no added salt, drained and flaked into moist mixes with vegetables or mashed onto toast. Keep servings occasional rather than a weekly staple, and rotate with salmon, sardines and white fish. Skip raw tuna entirely — seared, sashimi or sushi forms stay off the baby menu.

Warning signs to watch for

Fish allergy signs apply: hives, swelling, vomiting, rarely breathing difficulty. Mercury effects are cumulative and invisible short-term, which is exactly why the rotation habit matters more than watching for symptoms.

When to call for help

Plan fish variety with your pediatrician if tuna is a family staple. For allergy reactions involving breathing, seek emergency care immediately (911 in the US). US Poison Control: 1-800-222-1222.

Common questions

Which tuna is better for babies — chunk light or albacore?

Chunk light tuna generally comes from smaller, lower-mercury species, making it the usual pick for young children. Albacore is not banned, just the one to keep rarer.

Can my baby eat tuna every week?

An occasional serving is fine; the habit to avoid is tuna being the only fish on repeat. Rotation with low-mercury fish is the standard guidance.

What about tuna salad with mayo?

After the basics — cooked tuna, no added salt — a little mayonnaise is acceptable from 6 months. Watch for celery or onion bits that are choking-sized in ready-made versions.
