Honestly a little bit isnt going to harm you. Even with our lowered immune systems our bodies naturally have the ability to fight of small amounts of bacteria. A lot of the info out there tendz t scare people. Heck ive not stopped eating deli meat. The risk is super minimal that you would have the bacteria enter your body. Ive even heard of people eating tuna which is high in mercury, for their whole pregnancy and be just fine. Not saying to just go ahead and do it, but dont over worry yourself after having a little bit. Chances are there was nothing. If on a normal immune system eating that stuff is fine, most often then not a little bit still wont harm us. Think about it, in reality everything is bad for us...apparently most things end up causing cancer. Its rediculas. People ate that stuff before years ago without any issues. I wouldnt worry so much about those types of food as much as i would worry about which meds you are taking and smoking and drinking.
