Macaroni Salad and freaking out.

I have been craving macaroni salad lately. I brought some from the grocery store (the packaged stuff at the deli) yesterday and had a large portion of it for dinner last night and had it again for lunch. It was delish. BUT then it dawned on me to check the label AFTER the fact, and it said it had "egg" in it (part of the dressing it was mixed in).... So of course now I'm freaking out. If this was going to harm my baby (listeria, salmonella, etc..) I would have to become symptomatic and sick from the possible bacteria correct?!?  Or could I not have any symptoms of getting sick but yet the possible bacteria in the food could still harm my baby and potentially cause miscarriage?!?  I'm 12 weeks 1 day.....
