How long can cheese sit at room temperature?
Cheese is a beloved dairy product that is enjoyed all over the world, but it’s important to know how long it can safely stay out of the fridge. In general, cheese should not be left at room temperature for more than two hours. This is because cheese is a perishable food that can spoil when kept at room temperature, especially if it is soft, moist, or contains high fat content. When cheese is exposed to temperatures between 40-140°F, it can provide an ideal environment for bacteria to grow, which can cause foodborne illnesses.
- Fresh cheeses like ricotta, goat cheese, and feta can only sit at room temperature for up to two hours before they start to spoil.
- Semi-hard and hard cheeses like cheddar, Parmesan, and Swiss can stay out for up to four hours as long as they are in a small, tightly sealed container or wrapped in plastic wrap.
- Processed cheeses like American cheese slices can sit at room temperature for up to eight hours before they spoil.
It’s important to note that the time limit for cheese at room temperature is reduced if the room is warm or if the cheese has been previously opened. In any case, it’s always best to err on the side of caution and refrigerate cheese as soon as possible to prevent spoilage and foodborne illness.
Factors that Affect the Shelf Life of Cheese at Room Temperature
When it comes to cheese, it is important to exercise caution when storing it. Cheese is a perishable food item, and storing it at room temperature can lead to the growth of harmful bacteria, which can lead to foodborne illnesses. However, different types of cheese have varying shelf lives at room temperature, and several factors can influence this.
