Can You Leave Cheese Out Overnight?
No, it is not recommended to leave cheese out overnight.
The U.S.
Department of Health advises against keeping any perishable food, including soft cheeses, out of the fridge for more than 2 hours.
Soft cheeses like cottage cheese, cream cheese, brie, and fresh mozzarella should be thrown away if left out for 2 or more hours.
On the other hand, hard cheeses like cheddar, Parmesan, and Gouda can be rewrapped and put back in the fridge if left out for 2 hours, with a shelf life of up to 24 hours.
Moldy cheese can be dangerous if consumed accidentally, as it can contain mycotoxins and harmful bacteria such as E.coli, Listeria, and Salmonella.
To maintain freshness, it is best to store cheese between 34ºF and 38ºF (1ºC and 3ºC) and check for signs of mold or strange odors before consuming.
Quick Tips and Facts:
1. Contrary to popular belief, some types of cheese can indeed be safely left out overnight. Hard and aged cheeses like cheddar, Parmesan, and Swiss have a lower water content and higher salt content, making them less prone to bacterial growth. However, soft cheeses like brie, mozzarella, and blue cheese should be refrigerated.
2. Leaving cheese out overnight can actually enhance its flavors. When cheese is kept at room temperature, its flavors have a chance to develop and intensify. This is particularly noticeable with softer cheeses, as they become creamier and more aromatic when allowed to breathe outside the fridge.
3. The practice of leaving cheese out overnight has its roots in traditional cheese-making. Before the invention of refrigeration, cheese was often aged and ripened at room temperature, as it allowed for the perfect conditions for flavor development. This tradition still carries on today with certain types of cheese.
4. However, it is important to note that leaving cheese out overnight can make it more susceptible to mold growth. Even hard cheeses can develop mold if they are not stored properly. To prevent mold, it is recommended to wrap the cheese tightly in wax or parchment paper and place it in a cool, dry place.
5. If you accidentally leave cheese out overnight and it develops mold, you don’t necessarily have to throw it away. For hard cheeses, it is usually safe to cut off the molded part and continue enjoying the rest. However, if the cheese is soft or the mold appears to be toxic or widespread, it is best to discard it to avoid any potential health risks.
Soft Cheeses Left Out For 2 Hours Should Be Discarded
Soft cheeses like cottage cheese, cream cheese, brie, and fresh mozzarella, are delicate and highly perishable. According to the U.S. Department of Health, it is recommended not to keep any perishable food, including soft cheeses, out of the fridge for more than 2 hours. This is due to the potential growth of harmful bacteria at room temperature. Therefore, if you accidentally leave soft cheese out for 2 or more hours, it is advisable to discard it.
The reason behind this recommendation is that soft cheeses have a high moisture content, providing an ideal environment for bacteria to thrive. Bacteria such as Listeria monocytogenes and Salmonella can multiply rapidly in these conditions and pose a health risk if consumed. Therefore, it is crucial to be cautious and prioritize food safety by adhering to the recommended guidelines.

Shelf Life Of Hard Cheeses Vs. Soft Cheeses
When it comes to shelf life, hard cheeses have a longer longevity compared to soft cheeses. Hard cheeses can be stored for several weeks to months when properly refrigerated and handled. On the other hand, soft cheeses have a shorter shelf life due to their higher moisture content, which makes them more prone to spoilage.
To ensure the longevity of any type of cheese, it is essential to maintain proper storage conditions. Wrapping the cheese thoroughly in wax paper or parchment paper, followed by plastic wrap, can help protect it from molds and odors. Additionally, storing cheese at a temperature between 34ºF and 38ºF (1ºC and 3ºC) is recommended to maintain its quality and freshness.
Key Points:
- Hard cheeses have a longer shelf life compared to soft cheeses.
- Soft cheeses spoil faster due to their higher moisture content.
- Wrap cheese in wax paper or parchment paper, then use plastic wrap to protect it.
- Store cheese between 34ºF and 38ºF (1ºC and 3ºC) for best quality and freshness.
Dangers Of Consuming Moldy Cheese
Consuming moldy cheese can be risky, especially if the mold is harmful. While molds are a natural part of cheese production and some types of molds are safe to consume, others can contain mycotoxins and harmful bacteria such as E.coli, Listeria, and Salmonella.
Mycotoxins are toxic compounds produced by certain molds, and their presence in moldy cheese can have health implications. However, it is important to note that significant consumption of moldy cheese is required for these mycotoxins to cause severe illness. In most cases, consuming a small amount of moldy cheese, especially if it was left out for less than 2 hours, is unlikely to make you seriously ill.
Nevertheless, it is best to exercise caution and discard any cheese that shows signs of mold growth. These signs include fuzz, weird colors, and funky smells. Moldy cheese can lead to various symptoms such as vomiting, stomach pain, diarrhea, and in rare cases, even severe infections such as E.coli or salmonella. Some studies have also suggested a potential link between mycotoxins in moldy cheese and liver cancer, highlighting the importance of proper food safety practices.
