Cottage cheese lasts for different durations depending on whether it's opened or unopened.
Unopened vs. Opened Cottage Cheese
Here's a breakdown of how long cottage cheese typically remains good, based on guidelines from the U.S. Department of Health and Human Services (HHS):
| Status | Shelf Life |
|---|---|
| Unopened | Up to two weeks |
| Opened | Up to one week |
Important Considerations:
- Refrigeration: Always keep cottage cheese refrigerated at or below 40°F (4°C). This helps slow bacterial growth and maintain its quality.
- Expiration Date: Pay attention to the "use by" or "best by" date printed on the container. These dates provide a guideline, but quality might degrade before the printed date if not properly stored.
- Signs of Spoilage: Before consuming cottage cheese, check for signs of spoilage like:
- Sour or off odor
- Mold growth
- Slimy texture
- Discoloration
- Proper Storage: To maximize the shelf life of opened cottage cheese:
- Seal the container tightly after use.
- Use a clean utensil each time to avoid introducing contaminants into the container.
- Safety First: When in doubt, it is always safer to discard cottage cheese. Foodborne illnesses are a serious concern.
By following these guidelines, you can safely enjoy your cottage cheese while it's fresh and flavorful.
