Thanks everyone

I ate olives throughout my entire pregnancy with Madeleine (even vomitted them in labour *urgh*) but they were the ones in a jar. I guess my main worry was that they weren't in a jar and they were from the deli. I am hoping all will be fine... I am sure it will be. The plus is that they were really yummo on my pizza and I had no fears then because they were so hot.
Thanks again everyone for your help and advice
