Cooked chicken, if it has been handled, packaged and stored
properly should stay reasonably good up to 4 days in the
refrigerator. You can keep it longer if you freeze it.
People constantly ask for some type of verification that the food they eat will not make them ill. That is nearly impossible to do without bacteriological and chemical tests, so the best we can do is provide guidelines, like:
- Handle food in a sanitary manner (wash hands, clean & sanitize food-contact surfaces, protect from cross-contamination, package & store properly)
- Keep potentially hazardous food out of the temperature danger zone (140°F to 40°F). Keep hot foods hot and cold foods cold.
- Reheat leftover cooked foods thoroughly (to 165°F)
- Use food within a reasonable time
Research will give you different answers. Remember that they are only guidelines. In the end, you are responsible for what you feed yourself and your family. This adage is a good one to follow: When in doubt, throw it out.
