Expecting a baby and craving a maki roll? Hold off on hitting the sushi bar until after you’ve delivered. Dr. Shannon Clark, an obstetrician/ gynecologist and associate professor of maternal-fetal medicine at the University of Texas Medical Branch at Galveston, says that raw fish can contain harmful bacteria and parasites as well as high levels of mercury, especially in countries that don’t have stringent food industry standards. “Although fresh sushi is likely OK, there is never a guarantee that it is fresh, even in the United States,” Clark says. “As a result, we recommend that pregnant women avoid sushi altogether.” Instead, opt for cooked fish that is low in mercury, such as canned, chunk light tuna, trout and salmon.
