Quick answer
Can I still eat it?
Use this as a conservative screen before you rely on the storage window. If anything seems unsafe, discard it.
Greek Yogurt is within the fridge window if it stayed cold/dry as required and shows no discard signs.
Sealed / unopened: Check date
Signs Greek Yogurt has gone bad
- Pink, orange, or green mold, fizzy bubbles, sharp ammonia smell.
Still good if
- Watery whey on top — stir it back in. This is normal protein-water separation, not spoilage.
Discard immediately if
- Any visible mold of any color
- Container is bloated or hisses when opened
- Greasy or oily film on top
Why guidance varies
Dairy spoilage depends on initial pasteurization, fridge temperature, and how often the container is opened; manufacturer-printed dates assume continuous storage at 40°F (4°C) or below.
