Potentially hazardous food, such as cooked hamburger, should be left at room temperature for no more than 2 hours or one hour if the ambient temperature is very warm. At that point, the food should be refrigerated or reheated. Was this answer useful?
I have always heard 3 days is the max. But it never hurts to give it the old smell test.. If it smells like it has turned, it probably has, but I wouldn't keep it longer than 4. u can keep thawed hamburger in the fridge for 2 days. then use it right up. You should'nt keep it longer than a day. Because through mincing the meat the actual surface of the meat multiplies imensly giving bacteria more space to breed.
