Cheese Storage: How Long Can It Stay Unrefrigerated?

How long does cheese last out of the fridge? Well, it depends on the type of cheese. Hard cheeses, such as cheddar and Parmesan, can last longer at room temperature than soft cheeses, such as mozzarella or cream cheese. The former can be safely left out for up to four hours, while the latter should be discarded after two hours. This is because soft cheeses have a higher moisture content, making them more perishable and susceptible to bacterial growth and spoilage. Harder cheeses, on the other hand, have lower moisture levels, creating an environment less conducive to bacterial growth.

Hard cheeses can be left out of the fridge for up to four hours

Hard cheeses, such as cheddar, Parmesan, and Swiss cheese, can be safely left out of the fridge for up to four hours. These cheeses have a lower moisture content, which makes them less susceptible to bacterial growth and spoilage. In fact, research has shown that most hard cheeses can slow the growth of bacteria, making the chance of foodborne illness from consuming these cheeses extremely low.

While hard cheeses can be safely left out for a few hours, it is important to note that their quality and taste may start to deteriorate. Hard cheeses left out in open air tend to dry out, becoming crusty and crumbly, and losing their appealing texture. Therefore, while they may be safe to consume, it is recommended to only leave hard cheeses out of the fridge for up to two hours to maintain their optimal flavour and texture.

After being left out, hard cheeses should be inspected for any signs of spoilage before being placed back in the fridge. This includes checking for any bad smells, slimy surfaces, dark spots, dryness, cracks, or mould. If any of these signs are present, the cheese should be discarded.

To store hard cheeses in the fridge, it is recommended to remove them from their plastic packaging and wrap them loosely in a breathable material, such as wax paper or cheese paper. Then, place the cheese in an airtight container and store it in the coldest part of the fridge. Proper storage can help extend the shelf life of hard cheeses, which is typically about four weeks in the refrigerator.

In summary, while hard cheeses can be left out of the fridge for up to four hours without posing a health risk, it is best to limit the time to two hours to maintain their quality and taste.

Soft cheeses should be discarded after two hours at room temperature

Soft cheeses are more perishable than hard cheeses. This is because they have a higher moisture content, which makes them more susceptible to bacteria and spoilage. Therefore, soft cheeses should be discarded after two hours at room temperature.

The two-hour guideline for soft cheeses, such as cottage cheese, cream cheese, brie, and fresh mozzarella, is in line with the U.S. Department of Health's recommendation for perishable foods. After two hours, these cheeses are at a much higher risk of spoilage and bacterial growth, which can cause foodborne illnesses.

It is important to note that the two-hour guideline is a safety precaution, and the quality and taste of soft cheeses may start to decline before this time. To ensure the best flavour and texture, it is recommended to bring cheese to room temperature before serving, which generally takes about 20-30 minutes.

If you are serving a variety of cheeses, it is best to let the cheese come to room temperature for no more than two hours and then store any leftovers properly. Soft, fresh cheeses should be discarded if left out for longer than two hours, while hard cheeses, such as cheddar, Swiss, Gouda, and Parmesan, can be wrapped well and refrigerated for later use.

To properly store soft cheeses, it is recommended to keep them in their natural liquid in a plastic container. For soft-ripened or semi-soft cheeses like Brie, wrapping them in cheese paper, parchment paper, or an airtight container is best.

Perishable foods, including cheese, should not be left out for more than two hours

Hard cheeses, such as cheddar, Parmesan, and Gouda, can be left out for up to four hours without becoming unsafe to eat. This is because they have a lower moisture content, which makes them less susceptible to bacterial growth. However, it is important to note that leaving hard cheeses out for extended periods may impact their quality, taste, and texture. After four hours, hard cheeses should be checked for signs of spoilage before being wrapped and refrigerated.

The safety of cheese left out at room temperature also depends on other factors, such as how the cheese is made and how fresh it is. For example, pasteurized processed cheeses like American cheese are less perishable due to their blend of ingredients and heat treatment. Additionally, research has shown that most hard cheeses slow the growth of bacteria, so the chance of foodborne illness caused by cheese is extremely low.

To ensure food safety and maintain the quality of cheese, it is recommended to store it properly. Cheese should be wrapped loosely in a breathable material, such as wax paper or cheese paper, and placed in an airtight container in the refrigerator. Soft and semi-soft cheeses should be stored in their natural liquid in a plastic container. By following these storage guidelines, you can extend the shelf life of cheese and enjoy its rich flavor and versatility.

Cheese should be wrapped loosely in a breathable material and stored in an airtight container

Cheese is a versatile and tasty food, but it's perishable and can go bad. To extend its shelf life, it's important to store it properly.

Cheese needs to breathe, so wrapping it tightly in plastic wrap or a plastic bag is not ideal. This can reduce its quality and flavour, and it can also encourage the growth of unwanted bacteria. Instead, cheese should be wrapped loosely in a breathable material and stored in an airtight container. Wax paper or cheese paper are good options, and foil can be used for blue cheese.

For soft-ripened or "semi-soft" cheeses like Brie, wrapping them in cheese paper is best. You can also use parchment paper and keep them in an airtight container.

Semi-hard and hard cheeses should be removed from their plastic packaging and wrapped loosely in cheese paper or wax paper before being placed in an airtight container.

By storing cheese in this way, you can help to extend its refrigerator life. Soft cheeses will generally last about a week in the fridge, while semi-hard cheeses can last two to three weeks, and hard cheeses can last about four weeks.

Signs of spoilage include an unpleasant smell, slimy surface, dark spots, and mould

It's important to be vigilant when it comes to checking for signs of spoilage in cheese, as eating spoiled cheese can lead to food poisoning. Signs of spoilage include an unpleasant smell, a slimy surface, dark spots, and mould.

An unpleasant smell can be described as sweaty, chlorine-like, or ammonia-like. If your cheese gives off such an odour, it's best to discard it.

A slimy surface texture is another indication that your cheese has gone bad. This can be accompanied by a yellowed colour, mould, and sourness. Spoiled cheese with these characteristics should be thrown away.

Dark spots on cheese can indicate the presence of mould, which is a sign of spoilage. If you notice dark spots, it is recommended to cut off at least 1 inch (2.5 cm) around and below the affected areas before consuming the cheese. However, if the cheese is high-moisture, such as ricotta or cream cheese, it's best to discard the entire container as the mould can spread quickly.

Mould on cheese is a sure sign of spoilage. For blue cheeses, the presence of blue mould is intentional and safe to consume. However, other types of mould on cheeses like Cheddar or Swiss are not safe to eat. Cut off the affected portion and discard it.
