If there are any concerns, make stew. In addition to extracting a lot of amazing nutrients (especially if you are using the bones, marrow, cartilage, skin, etc.!!!), cooking your chicken and other meat for a couple hours completely kills all bacteria. And I mean dead, dead. 3+ hours at 212F (boiling) == Listeriamageddon.
