(HealthDay News) -- While fish typically is a healthy food, many types contain mercury. And because mercury exposure can harm a developing fetus, expectant moms should be cautious about how much fish they eat.
The U.S. Food and Drug Administration recommends these precautions for pregnant women who eat fish:
Avoid species that tend to contain high amounts of mercury, including tilefish, shark, king mackerel and swordfish.
Eat no more than 12 ounces per week of lower-mercury fish, such as canned light tuna, shrimp, catfish, pollock and salmon.
Before eating locally caught fish, check for any advisories.
If you cannot find information about the safety of local fish, eat no more than one 6-ounce serving in a single week, and avoid other fish that week.
