Raw eggs are a no-no during pregnancy, because they sometimes carry germs such as
salmonella.
Salmonella is a type of bacteria that can cause food poisoning, and in very rare cases, be fatal. Contracting salmonella during pregnancy rarely harms your baby directly, but the high fever, vomiting, diarrhea, and dehydration that accompany a bad case of food poisoning could cause preterm labor or miscarriage.
that's what I found on babycenter website.
