Can you eat chicken that was cooked and frozen but defrosted left out on the counter all night?

No, it is not safe to eat chicken that was cooked, frozen, and then left out on the counter overnight.

Here's why:

* Bacteria growth: When cooked chicken is left out at room temperature for extended periods, bacteria can multiply rapidly, even if it was previously frozen.

* Food poisoning risk: Eating food contaminated with bacteria can cause food poisoning, leading to symptoms like nausea, vomiting, diarrhea, and stomach cramps.

* Danger zone: The "danger zone" for bacterial growth is between 40°F and 140°F. Leaving cooked chicken at room temperature for an extended time puts it in this danger zone.

What to do instead:

* Refrigerate promptly: Cooked chicken should be refrigerated within two hours of cooking (or one hour if the temperature is above 90°F).

* Reheat thoroughly: If you must reheat cooked chicken, ensure it reaches an internal temperature of 165°F.

* Discard if unsafe: If you have any doubts about the safety of cooked chicken that was left out, it's best to throw it away.

It's always better to err on the side of caution when it comes to food safety.
