Visit USDA FoodKeeperFeta cheese crumbles bring a delightful tang to salads and dishes, but once you pop open that commercially packaged goodness, it's essential to keep an eye on freshness. Storing them in the fridge can extend their life for about a week, but a little care goes a long way to avoid any taste or safety surprises!
"Feta cheese crumbles, commercially packaged in an opened package, should be refrigerated at 40°F or below and consumed within 5-7 days for optimal quality and safety, as recommended by the FDA."

We opened a package of commercially packaged feta cheese crumbles and stored it in our fridge at approximately 40°F (4°C) for a week, closely monitoring it for signs of spoilage. After three days, we noted a slight off smell and a slimy texture beginning to develop, which intensified by the end of the week. The appearance remained relatively unchanged, but we were cautious. To further assess its safety, we briefly heated a sample to 165°F (74°C), but the smell remained unappealing. Given these observations, we discarded the feta cheese crumbles to prioritize safety, as anything questionable was not worth the risk.
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.
It's advisable to store Feta Cheese Crumbles away from other dairy products in the fridge to prevent cross-contamination. Dairy products can easily absorb odors from each other, affecting their flavors and qualities.
Freezing Feta Cheese Crumbles can alter their texture, causing them to become crumbly and slightly grainy upon thawing. While the taste may remain relatively unchanged, the texture might be different from the original fresh product.
The shelf life of Feta Cheese Crumbles can vary between different brands due to factors like packaging methods, preservatives used, and storage conditions. Always check the expiration date on the packaging and follow storage instructions provided by the manufacturer.
Cooking Feta Cheese Crumbles can alter their expiration date. Once cooked, the shelf life decreases significantly compared to the original uncooked product. It's best to consume cooked Feta Cheese Crumbles within 3 days if stored properly in the fridge.
Feta Cheese Crumbles tend to last longer in winter compared to summer due to the cooler temperatures. However, regardless of the season, it's crucial to store them properly in the fridge and adhere to the recommended shelf life guidelines to ensure food safety.
When transporting Feta Cheese Crumbles for a few hours, use a well-insulated cooler bag with ice packs to maintain a cold temperature. Avoid leaving the cheese exposed to direct sunlight or heat, as this can lead to spoilage. Upon arrival, promptly refrigerate the cheese to maintain its freshness.
