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?
If it has hamburger in it, I would only eat it up to a maximum of one week. If it is just tomato sauce you can reseal it and put it in the fridge for months. It should last 4-5 days with or with out the beef. It will mildly change color along with producing a slight odor when it isn't good anymore. I read somewhere that after something has been opened and refrigerated, eat it within 5 days.
