To keep yogurt from going bad fast, and protect you from being exposed to spoiled foods, it is important to keep in mind the length of time yogurt can stay at room temperature. Since, as we explained above, the U.S. Department of Agriculture says no perishable food should sit out more than two hours, Greek yogurt certainly cannot sit out overnight. While the already mentioned two hours might be too strict in some cases, leaving Greek yogurt out overnight is simply way too much time, so simply toss it immediately. Yes, Greek yogurt needs to be refrigerated if you want to make sure that it is safe to eat, because when left outside, it starts going bad after only something like two hours.

Yogurt is packed with good bacteria, but just like any perishable food, it can start growing bad bacteria fast when left out too long. The point is yogurt is packed full of good bacteria, but that does not magically make it immune from growing bad ones, either. Yogurt is more than just milk with an active culture of bacteria, it also contains acids and enzymes, both of which have a way of rotting pretty rapidly.

There is a misconception that because yogurt is made with fermented milk and it already contains bacteria, it does not spoil if left unrefrigerated. Leaving yogurt unrefrigerated for a longer period will cause the bacteria to grow and turn it acidic. Due to the high nutritional value of yogurt, it is not suitable for leaving yogurt outdoors for longer periods as warmer temperatures may accelerate the growth of bacteria, making this dairy product spoil more quickly. Even with its bacteria, yogurt will spoil if left outdoors for two hours or longer in temperatures between 41 and 90 degrees F.

At home, yogurt can become acidic and even spoil after sitting outside of the refrigerator longer than two hours. The state of the yogurt is based on not just how long it has been left outside, but also how much heat it has been exposed to. If room temperature is less than 40 degrees Fahrenheit, then you should consume refrigerated yogurt within an hour after keeping it at that temperature, once refrigerated. A store-bought refrigerated yogurt can be kept safely at room temperature for up to two hours, provided that the room temperature is at or above 90 degrees Fahrenheit.

Refrigerated yogurt (once opened) lasts for up to two weeks, whereas unrefrigerated yogurt (opened or not) will last for around a week. This is part of why yogurt kept refrigerated for quite some time will not spoil, while yogurt kept refrigerated lasts longer — often months.

Some folks may say that they leave yogurt out of the refrigerator for 6-7 hours, mainly when bringing it into work, and that is how good it tastes. Jeff Potter, an expert in food sciences, believes that yogurts may need to sit out of the fridge for up to eight hours, as temperatures are not exactly ideal where the microorganisms are growing. The U.S. Department of Agriculture says that yogurt sitting out at temperatures of 40 degrees to 90 degrees technically could sit outside for no longer than 2 hours and still be safe to eat.

If it is warmer than 90 degrees Fahrenheit, then you have just an hour to eat this yogurt sitting outside the fridge. For optimum freshness and shelf life, yogurt needs rapid refrigeration to 40 degrees F. or lower.
