The mayonnaise? I would hope it was pasteurized, but I don't know. All I know is that my son got food poisoning as a teenager (he's 34 now) from eating mayonnaise that was sitting out for awhile at a party--at least that's what we assumed it was. He had made a turkey sandwich with sliced turkey meat, cheese, mayonnaise, mustard and bread that was on a table outside at a party. I guess it could have been the turkey but upon questioning after the fact, he had said the mayonnaise had a filmy discoloration across the top (likely from the heat). Our family has been very careful eating things with mayonnaise that hasn't been refrigerated ever since. I don't know if other people that came to the party got ill or not.
