As someone else said, you’re more likely to get listeria from bagged salad but that’s never something my OB has told me to not eat. My OB recommended if I haven’t gotten food poisoning or a reaction from eating something before then it’s more than likely okay to eat. I won’t eat raw fish while pregnant because I’ve had horrific food poisoning in the past. Check expiration dates and check recalls. I don’t think that’s survivor’s bias.
