Food Safety Issues/soup left out


I left vegetable soup out all night it was still hot at 11pm it's 9 am now is it safe to eat it has ground beef in it

Hi Derek,

The recommendation is to not take a chance and eat potentially hazardous foods (meat, dairy, poultry,cooked vegetables, etc) that has been out in the Danger Zone - 41 to 135 degrees F -- for over 4 hours.  Since your soup was out a total of 10 hours and harmful bacteria, if present on the soup, could multiply to dangerous levels within that time frame, and since you can't see, taste or smell these bacteria to know if they are present, the recommendation is to pitch the soup.

I know you are thinking...."but couldn't I just reheat it to a rolling boil? Wouldn't that kill any bacteria present?"  While boiling would kill any live bacteria, the problem is that some bacteria produce a toxic waste product that is not deactivated by heat. In other words, heating a food does not make it automatically safe to consume.

The problem is you just can't tell by looking at the soup if it is still safe.  You could have this same scenerio 100 times and every time you reheated the soup it was perfectly fine.  Then the 101st get ill. Is it worth taking a chance????

So pitch the soup.....
