Opened Greek yogurt generally lasts one to two weeks in the refrigerator when stored properly.
Understanding Opened Greek Yogurt Shelf Life
Once you break the seal on a container of Greek yogurt, its shelf life significantly decreases compared to an unopened container. Exposure to air and potential contaminants from handling can accelerate spoilage. Knowing the typical timeframe for safe consumption is crucial for preventing foodborne illness.
USDA Guidance on Opened Yogurt
According to the USDA, opened yogurts are recommended to last only one to two weeks when kept in the refrigerator. This timeframe is based on maintaining proper storage conditions, specifically at temperatures of 40 degrees Fahrenheit or colder. Adhering to this guideline helps ensure the yogurt remains safe to eat within that period.
- Recommended Storage Time (Opened): 1 to 2 weeks
- Required Temperature: 40°F (4°C) or colder
Storing your opened Greek yogurt at the correct temperature is key to maximizing its safe shelf life within the recommended window.
Tips for Storing Opened Greek Yogurt
To help your opened Greek yogurt stay fresh for as long as possible within the one to two-week USDA guideline, follow these simple storage tips:
- Seal Tightly: Always ensure the lid is tightly sealed after each use to minimize air exposure.
- Use Clean Utensils: Use a clean spoon every time you scoop out yogurt to avoid introducing bacteria.
- Store Properly: Keep the yogurt consistently refrigerated at 40°F or below. Avoid letting it sit out at room temperature.
While visual or olfactory cues like mold, off smells, or significant changes in texture are signs that yogurt has gone bad, relying solely on these is not recommended. Following the recommended storage time from the USDA is the safest approach.
