Actually, listeria among pregnant women isn't that uncommon. Years ago I had an Aunt who gave birth to a stillborn baby at 32 weeks due to a listeria infection. She could only recall one instance where she ate a cold deli sandwich. Pregnant women are about 20 times more likely than other healthy adults to get listeriosis. About one-third of all reported cases happen during pregnancy. Listeria doesn't care about "moderation", as this person stated. All it takes is one meal- and I highly doubt anyone here cares more about lunch meat than the health of their unborn child. I've heard things on both ends about the nuts...I couldn't live without peanut butter! Its my main source of protein nowadays. One doctor told me that eating peanut butter is recommended because it could help build a peanut allergy immunity for your child, but other things i've read said the opposite. Who knows!
