Can you eat seared tuna while pregnant?
Not advisedNo, skip seared tuna during pregnancy. Searing only cooks the outer few millimeters, so the raw center still carries Listeria and parasite risk, and ahi tuna is a high-mercury fish on top of that.
Why
Two separate problems stack up here. First, the pink center of a seared or tataki-style steak is raw fish, and the CDC tells pregnant women to avoid raw and undercooked seafood because of Listeria, which can cause miscarriage, stillbirth and serious newborn illness. Second, the tuna used for searing is usually yellowfin or bigeye ahi, and the FDA lists bigeye tuna in its Choices to Avoid group for mercury, a metal that damages a baby's developing brain. A tuna steak cooked all the way through solves the first problem, and sticking to yellowfin or skipjack at one serving a week handles the second.
Safer alternatives
- Yellowfin tuna steak cooked to 145F all the way through, once a week
- Grilled salmon fillet
- Canned light skipjack tuna, in a salad or poke-style bowl
- Cooked shrimp poke bowl instead of ahi
- Fully cooked teriyaki salmon on rice

Frequently asked questions
I ate seared tuna before I knew I was pregnant, should I worry?
One meal is very unlikely to cause harm, and Listeria infection from a single serving is rare. Watch for fever, chills, muscle aches or diarrhea over the next few weeks and get checked if they appear. From now on, order your tuna cooked through.
Can I ask for my tuna steak well done instead?
Yes, that is the right move. Cooked to 145F so the flesh is opaque and flakes apart, tuna is safe from Listeria and parasites. Choose yellowfin or skipjack rather than bigeye, and keep it to one serving a week for mercury.
Is the seared tuna in a supermarket salad any safer?
No, it is still raw in the middle and has been sitting chilled, which is exactly the condition where Listeria multiplies. Ready-to-eat chilled seafood is a known risk for pregnant women. Pick a salad with cooked chicken, canned light tuna or cooked shrimp instead.
