i have asked my OB and GP about mayo and was told that if you open a new jar then you can eat it but only within 12hrs - after that it becomes a danger food. same with home made (literally home made) pate
i have never been strict with no may in pg, but this time round i am being very careful and only eat mayo when i have opened the jar (all i get is about 1tsp in whatever i am eating, so not really worth it.. )
and trust me the no mayo thing is really hard - we have a deli and almost every dip or salad has mayo in it.
DIDi, thats absolutely shocking about your friend - no words.
