Smoked salmon should not be consumed by pregnant women, according to the American Pregnancy Association. The organization also states that no other type of refrigerated smoked seafood should be eaten during pregnancy. Canned seafood is generally safe.
The danger that smoked seafood consumption poses is its possible contamination with listeria. Babycenter states that listeria is a harmful bacteria that can cause devastating problems for an unborn baby, even if the mother does not develop symptoms of infection, resulting in miscarriage, stillbirth or premature birth.
Smoked seafood is generally safe for pregnant women to eat if it has been thoroughly cooked, such as in a casserole.
