Greek yogurt typically lasts about 5 to 7 days in the refrigerator after opening when stored properly at or below 40°F (4°C). This timeframe assumes the container is sealed tightly and clean utensils are used to avoid contamination
. Some sources mention it can last up to 1 to 2 weeks after opening, but the safest recommendation is to consume it within a week to ensure freshness and avoid spoilage
. Signs that Greek yogurt has gone bad include:
- Sour or off smell
- Watery or curdled texture
- Visible mold or discoloration
- Unpleasant or sour taste
If you notice any of these signs, it is best to discard the yogurt to prevent foodborne illness
. Freezing Greek yogurt can extend its shelf life to 1-2 months, but it may alter the texture, making it better suited for cooking or smoothies rather than eating plain
. In summary, after opening, Greek yogurt should be eaten within about a week for best quality and safety, with careful attention to storage conditions and spoilage signs.
