How Long Does Yogurt Last in the Fridge?

When yogurt is kept tightly covered and in the fridge, it can last one to two weeks after the “sell by” date on the package. When the yogurt has been opened, it can be safely consumed for one week when kept in the fridge. Unopened yogurt typically lasts seven to fourteen days when properly stored.

Does Yogurt Go Bad?

Yes, yogurt does go bad once the expiration date has passed. However, it can spoil before then it isn’t stored correctly. Exposing yogurt to room temperatures or warmer increases the risk of bacterial contamination, which can cause food poisoning. As a result, yogurt should never be let out of the fridge for longer than two hours. Yogurt that has been opened will spoil faster than an unopened container. In addition, yogurts with added sugar and fruit may be more prone to bacteria growth.

How Should Yogurt Be Stored?

To keep yogurt safe to consume as long as possible, store it in an airtight container and make sure the lid is properly sealed. Yogurt can easily pick up other flavors due to its consistency if it does not have a tight lid. If the yogurt comes with a foil covering, replace it before putting it back in the fridge since it adds an extra layer of protection.

Keep yogurt at the back of the fridge and never in the door—the reason is that even a slight change in temperature can speed up the expiration process. The back of the fridge remains cool and consistent. It is important to note that refrigerators should be kept at 40 degrees F or below. Another option is to freeze the yogurt if you are not concerned about the texture. When unopened yogurt is frozen, it can be stored for one to two months before the quality begins to deteriorate.

How Do You Tell If Yogurt Has Gone Bad?

Signs of spoiled yogurt are similar to other dairy products. Look out for the following signs:

Excess Liquid

It is normal for some water to collect on the surface of yogurt, but if there is an unusual amount of liquid sitting on top, it can be a sign of spoilage. So it’s safer to toss it at that point.

Smell

If yogurt smells sour and like spoiled milk or sour cream, discard it immediately. Yogurt should have a fresh and pleasant smell. However, a slight sour note is still okay.

Curdling

If a once smooth yogurt has extra texture, it is probably best to throw it out. Curdling is a sign that the yogurt has seen better days.

Mold

Yogurt that has been sitting for too long in the fridge is prone to mold because of its water content. If there is any evidence of mold—white, green, or any color of growth—on your yogurt, it is spoiled.

Off Taste

If the look and smell of your yogurt don’t stop you from eating it, but it doesn’t taste right, throw it out.
