Blue cheese can be safely consumed months after its production
Blue cheese is a common type of cheese with a strong smell and distinct flavour. It is made using Penicillium, a type of mould that is responsible for its unique taste, smell, and appearance. This mould is safe to consume and does not produce toxins. However, blue cheese can still go bad, especially if it is not stored properly.
When stored properly, blue cheese can last for several weeks to a few months in the refrigerator. Proper storage involves keeping the cheese tightly wrapped in the refrigerator at all times, with the temperature set below 40 degrees Fahrenheit. If stored this way, blue cheese can last for about 1 to 2 months in the refrigerator, even beyond the "sell-by" or "best-by" date on the package.
To further extend the shelf life of blue cheese, it can be frozen. Freezing may alter the texture and appearance of the cheese, but it remains safe to consume indefinitely when stored at 0 degrees Fahrenheit. When properly frozen, blue cheese will maintain its best quality for about 6 months but can be kept safely beyond that time.
It is important to note that blue cheese can go bad if not stored properly or if consumed past its expiration date. To determine if blue cheese has gone bad, check for any changes in appearance, such as fuzzy white, green, pink, or grey spots on the surface, or changes in smell, such as an ammonia-like odour. If the cheese exhibits these signs, it should be discarded as consuming spoiled blue cheese can cause food poisoning.

It's important to store blue cheese properly to prevent it from spoiling
To prevent spoilage, blue cheese should be stored in the refrigerator at all times, tightly wrapped in plastic wrap or aluminium foil. For even better protection, wrap the cheese first in wax or parchment paper, then cover it with plastic wrap before refrigerating. The refrigerator temperature should be set below 40 degrees Fahrenheit. Properly stored, blue cheese will last for about one to two months in the refrigerator.
If you want to extend the shelf life of blue cheese even further, you can freeze it. Cut the cheese into portions no larger than half a pound each, then wrap them tightly in heavy-duty aluminium foil or plastic freezer wrap, or place them inside a heavy-duty freezer bag. Frozen blue cheese will maintain its best quality for about six months but will remain safe to consume beyond that time. However, freezing may slightly alter the texture and appearance of the cheese, and it may become crumbly.
To tell if blue cheese has spoiled, check the expiration date on the packaging and inspect its appearance and smell. Fresh blue cheese has a strong scent, but it changes as it starts to go bad. If the cheese has an ammonia-like smell or fuzzy white, green, pink, or grey spots on the surface, it should be discarded. Additionally, if the creamy part of the cheese is pink, brown, green, or blue, rather than white or beige, it has likely gone bad.

Blue cheese can be frozen to extend its shelf life
Blue cheese is a type of cheese known for its strong smell and distinct flavour. It is made using Penicillium, a type of mould that is responsible for its unique taste, smell, and appearance. While the mould used to make blue cheese does not produce toxins and is safe to consume, blue cheese can still go bad if it is not stored properly.
To extend the shelf life of blue cheese, it can be frozen. Freezing blue cheese can alter its texture and appearance, but it remains safe to consume indefinitely. When freezing blue cheese, it is important to wrap it tightly in heavy-duty aluminium foil, plastic freezer wrap, or place it inside a heavy-duty freezer bag. It is also recommended to cut the cheese into portions no larger than half a pound each before freezing. Properly stored, blue cheese will maintain its best quality for about 6 months in the freezer but will remain safe beyond that time.
It is important to note that softer cheeses with higher moisture content may not be the best candidates for freezing due to their tendency to form more ice crystals, which can significantly affect their structure and texture. Blue cheese is already a soft cheese, and freezing it may make it crumbly and better suited for cooked dishes like sauces, soups, and casseroles.
Additionally, while blue cheese can last a long time when stored properly, it can go bad. Signs that blue cheese has gone bad include the growth of unidentified substances on the cheese, a strong odour similar to ammonia, or changes in its appearance or smell. Consuming spoiled blue cheese can cause food poisoning, so it is important to practice basic food safety and store blue cheese properly.

Blue cheese is made using Penicillium, a type of mould that is safe to consume
Blue cheese is a common type of cheese with a strong smell and a distinct flavour. It is made using Penicillium, a type of mould that is responsible for its unique taste, smell, and appearance. Unlike other types of mould, Penicillium does not produce toxins and is safe to consume.
Penicillium is added during the cheesemaking process after the curds have been drained and rolled into wheels. The mould gives blue cheese its distinctive blue or green colour. While the mould in blue cheese is safe to eat, it's important to note that blue cheese can still go bad due to other types of mould or bacteria that may grow on it. Therefore, it's crucial to practice basic food safety and store blue cheese properly.
To keep blue cheese fresh, it should be stored in the refrigerator at all times and tightly wrapped. Properly stored, blue cheese can last about one to two months in the refrigerator. It is recommended to check the expiration date on the packaging and dispose of the cheese after three to four weeks. However, if the cheese is still within its expiration date and has been stored properly, it is generally safe to consume.
Blue cheese can also be frozen to extend its shelf life. When frozen, blue cheese can last about six months to indefinitely, depending on the storage conditions. However, freezing may alter the texture and appearance of the cheese, making it more suitable for cooked dishes.
To tell if blue cheese has gone bad, there are a few signs to look out for. If there is fuzzy white, green, pink, or grey mould growing on the surface, it is best to discard it. Additionally, if the cheese develops an ammonia-like smell or has a strange odour, it is likely spoiled. Consuming spoiled blue cheese can cause food poisoning, so it is important to practice caution and proper food handling.

How to tell if blue cheese has gone bad
Blue cheese is made using Penicillium, a type of mould that gives it a unique taste, smell, and appearance. Unlike other types of mould, Penicillium does not produce toxins and is safe to consume. However, blue cheese can still go bad, so it's important to practice proper food safety and storage.
- Check the expiration date: Blue cheese can last for 3-4 weeks in the refrigerator if properly stored. If it's past the expiration date, it's best to discard it.
- Smell the cheese: Fresh blue cheese has a strong scent, but it changes as it starts to spoil. If it has an ammonia-like smell, it is likely spoiled and should be discarded.
- Examine the colour: The creamy part of the cheese should be white or beige. If you notice pink, brown, green, or blue colours in the creamy part, it's a sign that the cheese has gone bad.
- Look for mould: While blue cheese already contains mould, new mould growth can indicate spoilage. Fuzzy white, green, pink, or grey spots on the surface of the cheese may indicate that it has gone bad.
- Check for softness: If the cheese becomes soft and has unidentified growth on it, it's best to throw it out. Softness indicates low acidity, which means the cheese is less safe to consume.
- Taste: If the cheese tastes moldy, it has likely gone bad. However, tasting spoiled cheese is not recommended as it can cause food poisoning.
To prevent blue cheese from going bad, it's important to store it properly. Wrap the cheese tightly in plastic wrap or aluminium foil, and make sure your refrigerator temperature is set below 40 degrees Fahrenheit. You can also freeze blue cheese to extend its shelf life.
