Fava beans are a safe option for pregnant women according to Livestrong. It is essential that pregnant women wash their fava beans prior to eating them. Unwashed produce may contain harmful bacteria and parasites that can cause food-borne diseases such as toxoplasmosis and listeriosis according to the FDA and the American Pregnancy Association.
According to the G6PD Favism Association, a case has shown that the intake of fava beans during pregnancy can cause favism in babies because of a possible G6PD deficiency. Out of an abundance of caution, pregnant women should consult their healthcare provider to make sure fava beans are safe to eat.
