Just to add to the general grossness, I recently had a conversation with a friend who got her MPH last year. She commented that if you get sick shortly after eating, and you're pretty sure it was the food, it was most likely fecal contamination. Things like salmonella and the like take longer to gestate. With the time frame given, it may have been unclean hands (your friends or the servers/cooks/etc) that were the culprit, not undercooked eggs.

Food for thought... if you feel like eating anytime soon, that is.
