Sashimi or any other raw seafood shouldn't be consumed during pregnancy, according to foodsafety.gov. This also applies to other high-risk people, such as the elderly, young children, and those with chronic conditions. However, this is a somewhat debatable topic as eating raw seafood doesn't have a negative impact on health while pregnant. Eating sashimi is relatively okay during pregnancy as long as you're eating at a well-established restaurant and seafood with safe mercury levels. Nonetheless, it might be best to hold raw seafood until birth.
