Question
I left a carton of yogurt (Dannon "Lite and Fit") out of the refrigerator for about 12 hours - at room temperture.  Am wondering if it is still safe to eat.  Thanks

Answer
Yogurt is typically acidic enough to prevent spoilage, and has a high level of competing organisms that prevent the growth of other organisms.  However, the product varies widely between manufacturers, so if the packaging recommends keeping the product refrigerated it should not be allowed to remain at room temperature for more than 4 hours.
