According to food safety guidelines, cooked chicken should not be kept in the refrigerator for more than four days. After four days, the risk of bacterial growth and foodborne illness increases significantly. Therefore, it is not recommended to eat cooked chicken that has been in the refrigerator for six days.
To ensure food safety, it's best to follow the "2-hour rule" when it comes to perishable foods like cooked chicken. This rule suggests that cooked food should not be left at room temperature for more than 2 hours. After that time, it should be promptly refrigerated to prevent bacterial growth.
If you have cooked chicken that has been in the refrigerator for more than four days, it's safer to discard it rather than risk potential foodborne illnesses. When it comes to food safety, it's always better to err on the side of caution.
