Can I eat baked sushi with a tiny peace of cooked shrimp and seaweed?if pregnant?

Cooked seafood is totally fine, so is raw sushi grade fish if it has been previously frozen to kill paracites (unless on the coast, most is, but you can check with the restaurant to confirm if you are thinking of having some). Other than that, just follow normal food safety guidelines regarding rice and stuff :)

Yep

Eat whatever as long as the meats cooked and not raw
