I think if you wash everything it is fine. I do follow everything to the t and don't eat any deli meats - even when heated. But with following all the rules last pregnancy, I had a still born daughter.... trust me, listeria was definitely up there in the causes they were testing for (about a million blood tests were taken before she was born). Once she was born, we knew she had died from a cord accident (around her neck so tight it left welts) but at least I knew I was safe with the listeria thing. Being pregnant again now, I'm doing it all the same, even though I think we've had our share of 'bad luck', I'm not game to risk it.
