Will eating a turkey that has been baked with the bag of giblets still in the cavity make you sick?

All poultry can possibly be contaminating with bacteria that can cause food poisoning. If the turkey has been frozen and the bag of giblets isn't washed and then isn't completely cooked, there is a possibility that it could be contaminated with bacteria. However, it is likely that the giblets would have completely cooked by the high temperature in the oven and that high temperature would have most likely killed any bacteria.

It is best to completely wash the bird in running water including rinsing the cavity, then pat it dry with paper towel then immediately cook.
