Pregnant women can eat shellfish as long as it is cooked.
They should not eat the organs or guts of fish or shellfish. Pregnant women may eat up to 12
ounces a week of crawfish, squid , oysters, clams , shrimp, or scallops. Because
some samples of lobster and crab may have much higher levels of mercury than
average, pregnant should limit crab and lobster to about 6 ounces per week.
The amount of mercury found in shellfish is generally much
lower than is found in other seafood. The table below shows the average
amount of mercury found in samples of shellfish along with the lowest and
highest amounts found in samples of each shellfish.
