Cheese is a staple food in many households, but leaving it out of the fridge can lead to bacterial growth and spoilage, especially in softer cheeses with higher moisture content. The length of time cheese can be left out depends on several factors, including the type of cheese, the temperature of the room, and how the cheese is made or how fresh it is. In general, hard cheeses such as Cheddar, Parmesan, and Gouda have lower moisture content and can be left out longer without spoiling, while soft cheeses like Brie, Camembert, and Mozzarella are more perishable and should be discarded if left out for too long. Proper storage methods, such as wrapping cheese tightly in wax or parchment paper, can also help extend its shelf life.
| Characteristics | Values |
|---|---|
| Whether cheese will go bad if left in heat | Cheese can stay out for up to six hours at 70°F or colder. However, if the temperature is above 90°F (32°C), cheese should not be left out for more than one hour. |
| Factors that determine how long cheese can be left out | Type of cheese, moisture content, whether it is fresh or aged, and the temperature of the room. |
| Types of cheese that can be left out longer | Harder cheeses like Cheddar, Parmesan, or Gouda have lower moisture content, making them less prone to bacterial growth. |
| Types of cheese that should not be left out for long | Softer cheeses with higher moisture content, such as Brie, Camembert, Queso Fresco, mozzarella, and cream cheese, are more perishable and should not be left out for more than two to four hours. |
| Impact of refrigeration on cheese | Refrigeration can cause cheese to dry out and lose quality. Cheese brought to room temperature has better flavour and texture. |
| Food spoilage | Food spoilage is caused by bacteria, resulting in changes in colour, flavour, texture, and aroma. Mould is the most common form of spoilage on cheese but can be cut off, leaving the rest edible. |
| Food poisoning | Food poisoning is caused by dangerous bacteria that reproduce on the food surface and can make you sick. Cheese left out may spoil but is unlikely to cause food poisoning. |

What You'll Learn
Hard cheeses can be left out of the fridge for longer than soft cheeses
Cheese is best stored in the refrigerator to prevent bacterial growth. However, it is safe to leave cheese out of the fridge for a short period, and doing so can even improve its flavour and texture. The length of time cheese can be left out of the fridge depends on the type of cheese and the temperature of the room.
Hard cheeses, such as Cheddar, Parmesan, and Gruyere, can be left out of the fridge for longer than soft cheeses. Hard cheeses have a lower moisture content, which makes them less susceptible to bacterial growth. They can be left out at room temperature for up to eight hours and will remain safe to eat. In fact, some sources claim that hard cheeses like Parmesan can be left out for up to 24 hours without spoiling.
Soft cheeses, such as Brie, Camembert, and mozzarella, have a higher moisture content and are therefore more perishable. They should not be left out of the fridge for more than two to four hours, as they can quickly deteriorate and spoil. Fresh cheeses, such as ricotta and goat cheese, fall into this category and should only be left out for 30 minutes to one hour.
It is important to note that the above guidelines assume an ordinary room temperature of around 70°F (20-22°C). If the temperature is above 90°F (32°C), the U.S. Department of Health recommends reducing the time cheese is left out of the fridge to one hour. Additionally, if cheese is left out of the fridge for too long, it may lose quality due to drying out and the separation of fat, even if it is still safe to eat.

Soft cheeses are more prone to bacterial growth
When soft cheeses are left out at room temperature, they provide a conducive environment for bacteria to grow and multiply. According to the U.S. Department of Health, soft cheeses should not be left out at room temperature for more than two hours. If the temperature exceeds 90°F (32°C), this time limit is reduced to one hour. Exceeding these limits increases the risk of bacterial growth, leading to spoilage and potential food safety concerns.
On the other hand, hard cheeses like Cheddar, Parmesan, and Gouda have a lower moisture content, making them less susceptible to bacterial growth. They can generally be left out at room temperature for longer durations, typically up to four hours or even eight hours, depending on the specific type of cheese and the ambient temperature.
It is worth noting that the risk of bacterial growth and food poisoning is relatively low in cheese, even when left out at room temperature. The aging process and the low water content of cheese make it less conducive to the growth of dangerous bacteria. However, spoilage bacteria can still cause changes in color, flavor, texture, and aroma, rendering the cheese unappealing and unsafe to eat.
To summarize, soft cheeses with their higher moisture content are more prone to bacterial growth, especially when left out of refrigeration. Adhering to recommended time limits for room temperature exposure and proper storage practices can help ensure the safety and quality of soft cheeses.

Refrigeration is not crucial for cheese storage
While refrigeration is a common method of storing cheese, it is not the only way to preserve this dairy product. In fact, refrigeration is not a crucial factor in storing cheese, as evidenced by the long history of cheese making, which far predates the invention of mechanical refrigeration. Here are several reasons why refrigeration is not essential for cheese storage:
Aging and Cheese Making
Cheese making involves an aging process where blocks of cheese are stored at temperatures ranging from 50 to 59 degrees Fahrenheit, often for weeks, months, or even years. This process is essential for producing high-quality cheese, and it occurs without mechanical refrigeration.
Pasteurized Cheese
Pasteurized processed cheeses, such as American cheese, are designed to withstand longer periods without refrigeration. Their blend of ingredients and heat treatment makes them more resistant to spoilage.
Hard Cheeses
Hard cheeses, such as Cheddar, Parmesan, and Gouda, have a lower moisture content, which makes them less susceptible to bacterial growth. These cheeses can typically be left out at room temperature for up to eight hours and will not spoil as quickly as softer varieties.
Room Temperature for Flavor
Bringing cheese to room temperature before serving is recommended to enhance its flavor and texture. Cheese served straight from the refrigerator can be dull, flavorless, dry, crumbly, or rubbery. Allowing cheese to warm up for 20 to 30 minutes before serving improves its taste and texture, providing a better culinary experience.
Alternative Storage Methods
While refrigeration is one option, it is not the only way to store cheese. Traditional methods, such as wrapping cheese in wax paper or parchment paper and then placing it in an airtight container, can effectively preserve cheese. Additionally, storing cheese in a cool, dark cellar or cupboard can be a viable alternative to refrigeration, especially if the cheese is consumed within a short period.
In conclusion, refrigeration is not the sole method for storing cheese. By understanding the characteristics of different cheeses and employing alternative storage techniques, it is possible to preserve and enjoy cheese without relying solely on refrigeration.

Cheese can be left out for 2-8 hours, depending on type
Cheese is a staple food in many households, but how long can it be left out of the fridge before it goes bad? Well, it depends on several factors, including the type of cheese, how it's made, and how fresh it is.
Soft Cheeses
Soft cheeses with high moisture content, such as cottage cheese, cream cheese, queso fresco, Brie, Camembert, and fresh mozzarella, are more perishable and should not be left unrefrigerated for more than two to four hours. Their high moisture content encourages bacterial growth, which can lead to spoilage and food safety concerns. Therefore, it is best to discard soft cheeses if left out for longer than the recommended time.
Hard Cheeses
On the other hand, hard cheeses like Cheddar, Parmesan, and Gouda have a lower moisture content, making them less susceptible to bacterial growth. They can be left out at room temperature for up to eight hours and even longer in some cases. Hard cheeses have a longer shelf life when left out but should still be monitored for signs of spoilage, such as a bad smell, slimy surface, dark spots, dryness, cracks, or mould.
Pasteurized Processed Cheeses
Pasteurized processed cheeses, such as American cheese, are designed to withstand longer periods without refrigeration due to their blend of ingredients and heat treatment. These cheeses can be left out for more extended periods, but it is essential to follow the manufacturer's recommendations and monitor for any signs of spoilage.
Fresh Cheeses
Fresh cheeses, such as mozzarella, ricotta, and young goat cheese, only need to be left out for 30 minutes to reach the ideal temperature. Leaving them out for longer can affect their quality and increase the risk of spoilage.
Temperature Considerations
It is important to note that the above guidelines assume an ordinary room temperature of around 70°F (21°C). If the temperature is higher, the safe window for leaving cheese out decreases. According to the U.S. Department of Health, cheese should not be left out at room temperature for more than two hours, and if the temperature is above 90°F (32°C), this limit reduces to one hour.
In summary, the length of time cheese can be left out depends on its type, moisture content, and the ambient temperature. Soft cheeses should be treated with caution, while hard cheeses can withstand longer periods at room temperature. However, to ensure food safety and maintain the best flavour and texture, it is generally recommended to store cheese in the refrigerator and bring it to room temperature before serving.

Cheese should be covered to prevent drying out
Cheese is best stored covered to prevent it from drying out. While refrigeration is a modern invention, cheese has been around for at least 7,500 years. In fact, one of the most important stages of cheesemaking is the aging process, which sees newly shaped blocks of cheese stored at temperatures ranging from 50 to 59 degrees Fahrenheit for weeks, months, or even years.
However, while refrigeration is not crucial for storing cheese, it is important to note that cheese should not be left out at room temperature for more than two hours, according to the U.S. Department of Health. If the temperature is above 90°F (32°C), this limit reduces to one hour. This is because cheese can spoil if left unrefrigerated for too long, and the safety window depends on the type of cheese, primarily its moisture content and whether it is fresh or aged.
Hard cheeses, such as Cheddar or Parmesan, have lower moisture content and can sit out longer without spoiling. They can be left out at room temperature for up to eight hours. On the other hand, soft cheeses, such as Brie or Camembert, have a higher moisture content and are more perishable. They should not be left unrefrigerated for more than two to four hours.
When storing cheese, it is recommended to wrap it tightly in wax paper or parchment paper, then place it in a plastic bag or airtight container. This helps to prevent the cheese from drying out while allowing it to breathe. It is also important to only take out the amount of cheese needed from the fridge, as taking cheese in and out of the fridge can cause it to spoil quickly.
