Any meat that has been left at room temperature for more than two hours or outdoors in temperature in excess of 90 degrees Fahrenheit for more than one hour should be thrown away, the USDA reports. Not the case with yours. You have no way of knowing where your IT's were during the cool down period.
I am a thrill seeker however, Bump the temp back up and let her rip. Seriously though, there are some types of bacteria that will not be killed or eradicated by mere temperature. Be careful my friend.
When in Doubt......check with the officials....then throw it out!
