Yogurt lasts longer than milk, but it can still spoil over time. Changes in smell, texture, and taste are key warning signs.
How to tell if yogurt has spoiled
Yogurt is spoiled if it smells unpleasant, develops mold, or separates excessively.
Signs yogurt is no longer safe
Fresh yogurt smells mildly tangy and has a smooth, creamy texture.
- Strong sour or rotten smell
- Mold spots on the surface
- Watery separation with curdled texture
Is liquid on top always a problem
A small amount of liquid whey on top is normal and can be mixed back in. Excessive separation with bad smell indicates spoilage.
If mold appears anywhere in the container, the entire yogurt should be discarded.
Common yogurt storage mistakes
- Eating yogurt long after opening.
- Using dirty utensils inside the container.
- Leaving yogurt unrefrigerated for extended periods.
Conclusion
If yogurt smells bad, has mold, or looks curdled, it is not safe to eat.
