7 days
Mold growth, off smell, slimy texture

As feta cheese crumbles age, they may become drier, harder, and lose their flavor. While they may still be safe to eat past the expiration date if stored correctly, the quality and taste may deteriorate. It is best to consume feta cheese crumbles within a few days after opening for optimal taste and texture.
When determining if commercially packaged opened feta cheese crumbles have gone bad, look for any mold growth, slimy or discolored patches, or an off-putting sour smell. Additionally, check for any changes in texture such as clumping or excessive moisture. If you notice any of these signs, it's best to discard the feta cheese crumbles to avoid foodborne illness.
Feta cheese crumbles can pose a risk for foodborne illnesses such as Listeria monocytogenes and E. coli if not stored properly. To prevent contamination, always refrigerate feta cheese crumbles below 40°F (4°C) and consume them within the recommended time frame.
To keep feta cheese crumbles fresh, store them in an airtight container or resealable bag in the refrigerator. For added freshness, place a paper towel in the container to absorb excess moisture and prevent mold growth. Avoid storing feta cheese crumbles near strong-smelling foods as they can easily absorb odors.
Feta cheese is a cornerstone of Greek cuisine and has been made for centuries. In fact, the name 'feta' is protected by European Union law and can only be used for cheese made in specific regions of Greece. Feta is traditionally made from sheep's milk or a combination of sheep's and goat's milk, giving it a unique tangy flavor.
You can safely store an opened package of Feta Cheese Crumbles in the fridge for up to 7 days. It's important to keep it tightly sealed to maintain freshness and prevent contamination.
If Feta Cheese Crumbles have been left at room temperature for a few hours, it's best to discard them to avoid any potential food safety risks. Bacteria can multiply rapidly at room temperature, increasing the risk of foodborne illness.
The type of container can impact the shelf life of Feta Cheese Crumbles. Opt for airtight containers or resealable bags to maintain freshness and prevent moisture loss. Avoid containers that are not food-safe or do not seal properly.
