pizza: I ate some pizza that had been left out on the counter for probably close to 15 hours. I figured there wasn't really anything on it that could go bad as it was just cheese pizza. I haven't been feeling great since though. Could it have been spoiled? What could spoil on a plain cheese pizza that was fully cooked?|||Did you nuke it before you ate it? Nuking kills all the bacteria and makes it safe to eat again so as long as you did you should be fine.|||The cheese could of spoile food really needs to be put in the fridge no later than 3 hours after being out|||=== EEWWW!! Food should not be left at room temperature for more than 2 hours. Bacteria begins to form at that point. ======================================鈥?/div> 2 years ago Report Abuse |||I wouldn't give it more than 8 hours...besides, it turns dry and cardboardy, and soggy - yech!|||i have eaten plenty of day old room temp 'za and not gotten sick.|||idk
