When will a cooked turkey go bad leaving it out?
No one can tell you when a cooked turkey will go bad, even if it is left out of the refrigerator. That will depend upon several things, including environmental factors and whether or not it was exposed to contaminants.
It is best to see that leftover cooked food is refrigerated within 2 hours or less.
If you pulled out the leftovers and forgot to put them back in the refrigerator, it will be up to you to determine if salvaging it is worth the risk.
