I don't know if I would trust sushi from a restaurant, because the main problem is the rice, and while they make them fresh, the rice may have been cooked the day before ITMS?

Safer to make your own sushi at home and eat it straight away.

Sushi rice is NOT cooked in advance - it cannot be.

I ate sushi throughout both pregnancies without incident.
The cause of concern in sushi is the rice, but if it is prepared in a clean environment and eaten that day, then your risk is low. Buy from trusted stores, with a high turnover and as early in the day as possible.
