yes it is best to avoid processed meats..especially the ones from the deli. But pizza when its hot enough will kill the bacteria, so thats why we are eating it hot. If its not hot then there has been a window of oppertunity to grow bacteria and all the nastys. You can eat pizza just if u have to heat it up some more when u get it home. But i wouldnt advise u going and having a straz sandwich or something..

i hope that helped...
