Yogurt expiration: 5 telltale signs your dairy delight has gone sour!
What To Know

- A mild sourness is normal, but a strong sour odor indicates spoilage.
Yogurt, a beloved dairy staple, offers a myriad of health benefits. However, consuming expired yogurt can lead to unpleasant experiences and potential health risks. This comprehensive guide will empower you with the knowledge to confidently determine whether your yogurt has reached its expiration date.
Signs of Yogurt Spoilage
1. Mold Growth: The presence of mold, typically white, green, or blue, is an unmistakable sign of spoilage. Discard any yogurt with visible mold.
2. Sour Smell and Taste: Yogurt naturally has a mild tang, but an overpowering sour odor or taste indicates spoilage.
3. Whey Separation: Yogurt’s whey, the liquid that separates from the solids, may accumulate on the surface. While some whey separation is normal, excessive amounts indicate spoilage.
4. Bloated or Leaking Container: A bloated or leaking container suggests the presence of gas-producing bacteria, a sign of spoilage.
5. Discolored Yogurt: Yogurt should maintain its original white or slightly yellowish color. Any significant discoloration, such as pink or brown, indicates spoilage.
6. Texture Changes: Spoiled yogurt may become watery, slimy, or lumpy, losing its smooth and creamy consistency.
7. Yeast Growth: Yeast, which appears as small white or brown spots, can also spoil yogurt.
How to Store Yogurt Properly
To maximize the shelf life of your yogurt, follow these storage guidelines:
- Refrigerate Promptly: After purchase, refrigerate yogurt immediately and maintain a temperature of 40°F (4°C) or below.
- Keep Yogurt Covered: Always keep yogurt containers tightly sealed to prevent contamination and moisture loss.
- Avoid Freezing: Freezing yogurt alters its texture and flavor, making it unappetizing.
Expiration Dates and Shelf Life
Yogurt expiration dates are typically printed on the container. However, these dates are not always foolproof. Here’s how to interpret expiration dates:
- “Sell By” Date: Indicates the last day the yogurt should be sold. Consume within a few days after this date.
- “Best By” Date: Indicates the recommended date for optimal quality. Yogurt may still be safe to consume for a short time after this date.
- “Use By” Date: Indicates the last date the yogurt should be consumed. Do not consume after this date.
How Long Does Yogurt Last?
The shelf life of yogurt varies depending on its type and packaging:
- Regular Yogurt: 7-14 days after opening
- Greek Yogurt: 14-21 days after opening
- Flavored Yogurt: 5-7 days after opening
- Unopened Yogurt: 1-2 months past the expiration date
When in Doubt, Throw It Out
If you’re uncertain about the safety of your yogurt, it’s best to discard it. Consuming spoiled yogurt can lead to foodborne illnesses, including nausea, vomiting, and diarrhea.
