Leaving Cheese Out: How Long Is Too Long?

Cheese is a staple at parties and get-togethers, but how long can it be left out before it goes bad? The answer depends on several factors, including the type of cheese, the temperature of the room, and how the cheese is made. Soft cheeses, such as mozzarella, cream cheese, and brie, have a higher moisture content and are more perishable, so they should not be left out for more than two hours. Harder cheeses, like cheddar, Parmesan, and Gouda, have a lower moisture content and can be left out for up to four hours. However, it's important to note that leaving cheese out for longer than two hours may impact its quality and taste. To ensure food safety and the best flavor, it's recommended to take cheese out of the fridge about 20-30 minutes before serving to bring it to room temperature.

Soft cheeses like Brie or Camembert should be discarded after four hours

According to the USDA, perishable foods, including soft, not hard, cheese, should be thrown out if left out at room temperature for longer than two hours. However, this guideline is mostly for food safety reasons, and the cheese may start to deteriorate in quality before then.

To slow bacterial growth, it is best to keep soft cheeses refrigerated until you are ready to eat them. Then, take the cheese out of the fridge about an hour before serving to let it come to room temperature. This will also improve its flavour and texture.

If you do leave soft cheeses out for more than four hours, it's best to throw them away. However, if you're feeling brave, it's unlikely that you'll face food safety issues if you leave cheese at room temperature for slightly longer than four hours.

Hard cheeses like cheddar can be left out for up to eight hours

Hard cheeses, such as cheddar, can be left out of the fridge for up to eight hours and remain safe to eat. This is because hard cheeses have a lower moisture content, which discourages bacterial growth. In fact, research has shown that most hard cheeses can slow the growth of bacteria, so the chance of foodborne illness caused by cheese is extremely low.

That being said, hard cheeses like cheddar will likely start to dry out and lose their appeal after four or five hours of sitting out at room temperature. As such, it is recommended that you put any leftover cheese back in the fridge as soon as you're finished eating it.

To ensure the best flavour, it is recommended that you allow hard cheeses to come to room temperature before serving. This generally takes about 20-30 minutes, but hard cheeses like cheddar only need about an hour. When cheese is cold, the fat molecules contract, making it much harder to determine the flavour. At room temperature, these molecules relax, releasing strong, flavourful aromas. The texture of the cheese also becomes softer and creamier, and the warmer temperature allows the mouth and nose to better appreciate the flavour.

If you are still squeamish about leaving cheese out at room temperature, it is best to stick with harder cheeses such as Parmesan. These are better able to maintain their unique flavour and functionality characteristics and are less of a food safety risk, even when held outside of ideal conditions.

Fresh cheeses like mozzarella or ricotta should be left out for no more than 30 minutes

Fresh cheeses like mozzarella or ricotta are more perishable than harder cheeses. This is because they have a higher moisture content and are not ripened or aged, making them more susceptible to bacteria and spoilage. Therefore, it is recommended that these types of cheeses are only left out of the fridge for a maximum of 30 minutes to two hours.

According to Adam Brock, director of food safety, quality, and regulatory compliance at Dairy Farmers of Wisconsin, all cheeses should only be kept out of the fridge for a maximum of four hours to avoid bacterial growth and spoilage. However, this limit is lower for fresh cheeses like mozzarella and ricotta. After being left out for too long, these cheeses will spoil and will no longer be safe to eat.

To ensure the best flavour, it is recommended that cheese is allowed to come to room temperature before serving. This generally takes around 20-30 minutes, so this should be factored into your preparation time. However, if you are planning to leave fresh cheese out for the duration of a party, it is best to stick to harder cheeses like cheddar, Parmesan, or Gouda, which have a lower moisture content and are less susceptible to bacterial growth.

If you do choose to put out fresh cheeses like mozzarella or ricotta, make sure to keep them out for no more than 30 minutes to two hours and keep them refrigerated for the rest of the time. By following these guidelines, you can ensure that your cheese is safe to eat and maintains the best flavour and texture.

Perishable foods, including soft cheese, should be thrown away after two hours, according to the USDA

Harder cheeses, such as cheddar, Swiss, Gouda, and Parmesan, can be left out for longer—up to eight hours, in fact. This is because they have a lower moisture content. However, it's worth noting that all cheese is best enjoyed within two hours of being removed from the fridge, as this is when its flavour and texture are at their peak.

If you're planning on leaving cheese out for a party, it's worth bearing in mind that different varieties will have different shelf lives outside of the fridge. While soft cheeses should be discarded after two hours, harder cheeses can be wrapped and refrigerated to be enjoyed another time.

It's also important to remember that cheese is a perishable food product and, as such, is susceptible to bacterial growth if left out for too long. The chance of foodborne illness from cheese is extremely low, but it's always better to be safe than sorry. If you're unsure whether a cheese is safe to eat, it's best to throw it out.

Waxed truckles can be left unrefrigerated for up to 24 hours

Waxed cheese can be left unrefrigerated for up to 24 hours. This is because the wax keeps the cheese cooler for longer, preventing spoilage and harmful bacteria. However, if the integrity of the wax has been compromised through heat or damage, it is recommended to treat it like unwaxed cheese and leave it unrefrigerated for no longer than 8 hours.

In general, cheese should be kept refrigerated and stored below 5°C to ensure it is safe to eat and lasts longer. However, there are different guidelines for different types of cheese. Soft cheeses such as brie and camembert can be left out of the fridge for up to four hours at room temperature. This is because their higher moisture content encourages bacterial growth. Hard cheeses such as cheddar, on the other hand, can be left out of the fridge for up to eight hours at room temperature due to their lower moisture content.

It is worth noting that while waxed cheese can be left unrefrigerated for up to 24 hours, it is still recommended to enjoy it at room temperature. This is because bringing cheese to room temperature helps to loosen the fat, giving the cheese a better texture and flavour. Therefore, it is suggested to take your cheese out of the fridge about 20 to 30 minutes before serving.

While it is safe to leave cheese unrefrigerated for a few hours, it is still best to place any leftover cheese back in the fridge as soon as possible. This will help maintain its freshness, taste, and texture.
