Blue cheese is made using a type of mold called Penicillium, which is responsible for its distinct taste, smell, and appearance. While most molds produce toxic compounds called mycotoxins, the Penicillium mold used in blue cheese production does not produce toxins and is safe to consume. However, blue cheese can still go bad, and it is important to practice proper food safety and storage. Fuzzy white, green, pink, or grey spots on the surface of blue cheese may indicate that it has gone bad. Additionally, a strong ammonia-like odor may indicate spoilage. Consuming spoiled blue cheese can lead to food poisoning, causing nausea, vomiting, diarrhea, and stomach cramps. Proper storage, such as wrapping and refrigerating, is crucial to prevent spoilage and ensure the safe enjoyment of blue cheese.

Blue cheese is made using Penicillium, a type of mold that is safe to consume
Blue cheese is made with Penicillium, a type of mould that is safe to consume. Unlike other types of mould, Penicillium does not produce toxins and is safe for human consumption. In fact, it is added to cheese after the curds have been drained and shaped into wheels. The blue cheese is then left to age for 2–3 months before it is ready to be enjoyed. Penicillium is responsible for blue cheese's distinct taste, smell, and appearance.
The mould that is used to make blue cheese does not produce any harmful substances and is safe for human intake. The mould that is safe to consume includes Penicillium roqueforti and Penicillium glaucum. These mould cultures are nontoxic and safe for human consumption. The entire world's yearly supply of Roquefort cheese, about 18,000 tons, comes from the small southern French village of the same name.
Blue cheese is a flavoursome fermented cheese featuring characteristic blue veins or marbling. The process of creating blue cheese involves mixing Penicillium roqueforti mould cultures with milk to begin the fermentation process. Blue cheese is rich in calcium, which is essential for healthy teeth and bones. The cheese also contains other nutrients that may help promote immune, cardiovascular, and cognitive functioning.
However, people should consume blue cheese in moderation due to its high levels of saturated fat, calories, and sodium. It is important to store blue cheese properly and practice food safety to prevent negative side effects and enjoy blue cheese safely. Blue cheese should be discarded if there are any changes in its appearance or smell. Consuming spoiled blue cheese can cause food poisoning and increase exposure to harmful mycotoxins.

Blue cheese can go bad and develop harmful molds if not stored properly
Blue cheese is made using Penicillium, a type of mold that gives it its distinctive taste, smell, and appearance. Unlike other molds, Penicillium does not produce toxins and is safe to consume. However, blue cheese can go bad and develop harmful molds if not stored properly.
When blue cheese is exposed to inadequate oxygen levels, its mold metabolism changes, resulting in unusual flavors and colors. Therefore, it is not recommended to pack blue cheese in a vacuum seal. Instead, it should be wrapped in parchment paper and then in beeswax paper, allowing it to breathe and preventing moisture buildup that fosters harmful mold growth.
Blue cheese that has gone bad will exhibit fuzzy white, green, pink, grey, or black splotches of mold. It may also develop pink and yellow yeast spots or emit a strong ammonia-like odor. Consuming spoiled blue cheese can lead to food poisoning, causing nausea, vomiting, diarrhea, and stomach cramps.
To prevent blue cheese from spoiling, it is crucial to follow proper storage practices. Blue cheese should be tightly wrapped and stored in the refrigerator. Additionally, it is important to check the use-by date and consume the cheese before that date. By taking these precautions, you can ensure the safety and quality of your blue cheese.

Harmful molds usually grow on food that hasn't been used for many days
Mould requires oxygen to grow and survive. When mould is denied adequate oxygen, its metabolism changes and can lead to unusual flavours and colours. This is why blue cheese should never be packed in a vacuum pack.
Blue cheese 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. However, blue cheese can go bad if it is not properly stored. Therefore, it is important to store blue cheese tightly wrapped in the refrigerator.
Harmful moulds typically grow on food that hasn't been used for many days. The mould that is used to make blue cheese, on the other hand, does not produce any harmful substances and is safe for human consumption. However, it is important to note that blue cheese can still go bad. If you spot fuzzy white, green, pink, or grey spots on the surface of blue cheese, it has likely gone bad. Additionally, if the cheese develops a strong odour similar to ammonia, it is probably spoiled. Consuming spoiled blue cheese can lead to food poisoning, causing nausea, vomiting, diarrhoea, and stomach cramps.
To prevent the growth of harmful moulds on food, it is important to practise proper food storage and handling. Store perishable foods in the refrigerator, ensure that food is properly wrapped or covered, and follow recommended use-by dates. Additionally, maintain a clean and dry environment, as mould thrives in damp conditions and can quickly spread once it starts growing.
In summary, while blue cheese can safely be consumed even when it exhibits mould, other foods with extra mould should be discarded. Harmful moulds usually grow on food that hasn't been used for many days, and consuming spoiled food can lead to negative health consequences. Therefore, it is important to be vigilant about food storage and practise good food hygiene to prevent the growth of harmful moulds.

Blue cheese with ammonia odour is safe, but strong ammonia smell may indicate spoilage
Blue cheese is made using Penicillium, a type of mould that gives it its distinct 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, and it's important to practice basic food safety and store it properly.
Blue cheese with an ammonia odour is generally safe to consume. The ammonia smell in blue cheese is caused by nitrogenous compounds released during the breakdown of proteins in the cheese. However, if the ammonia smell is strong, it may indicate spoilage. A slight ammonia smell is typical of blue cheese due to the presence of Penicillium mould, but a strong ammonia odour can indicate the presence of other moulds and bacteria that have taken hold.
When blue cheese spoils, it can develop a strong ammonia odour, colourful tufts of mould, and discolouration. Spoiled blue cheese can also exhibit physical signs such as a slimy or gritty texture. It is important to inspect the cheese for any changes in appearance or smell. Consuming spoiled blue cheese can lead to food poisoning, causing nausea, vomiting, diarrhoea, and stomach cramps.
To prevent spoilage, it is recommended to store blue cheese properly by wrapping it tightly in the refrigerator. When stored correctly, blue cheese can last 3–4 weeks in the refrigerator. Freezing blue cheese can further extend its shelf life, although it may slightly alter its texture and appearance.
In summary, while blue cheese with a slight ammonia odour is safe to consume due to the presence of Penicillium mould, a strong ammonia smell may indicate spoilage caused by other moulds and bacteria. It is important to inspect the cheese for any signs of spoilage and practise proper food safety and storage to prevent negative health effects associated with consuming spoiled blue cheese.
