Blue cheese is a type of cheese that is made using cultures of a type of mould called Penicillium. The mould gives the cheese its distinctive colour, flavour, and aroma. While blue cheese is made with mould, it is not harmful and is safe to consume. However, blue cheese can go bad if it is not stored properly, and it is important to practice basic food safety and wrap and refrigerate it.

Blue cheese gets its colour and flavour from the fungus Penicillium roqueforti
Blue cheese gets its distinctive colour and flavour from the fungus Penicillium roqueforti. This fungus is a saprophyte, meaning it grows on decaying organic matter, and it can be isolated from soil, plants, and other organic matter. It is widespread in nature and is commonly used in cheesemaking.
Penicillium roqueforti is added to the cheese after the curds have been drained and formed into wheels. It is responsible for the breakdown of fat through a process called lipolysis, which leads to the formation of fatty acids. These fatty acids are then converted into a group of molecules called ketones, which give blue cheese its unique smell and flavour. The specific ketones produced depend on the type of mould used, and they contribute to the overall aroma of the cheese.
In addition to its role in flavour development, Penicillium roqueforti also contributes to the texture of blue cheese. The proteolytic enzymes produced by the fungus act to soften the curd and produce the desired body in the cheese. This fungus is particularly important for the production of interior mould-ripened cheeses, where it is critical for flavour and texture development through its enzymatic activity. The growth of the fungus in cavities within the cheese results in the characteristic blue-veined appearance of blue cheese.
While Penicillium roqueforti is safe for human consumption and is used to produce blue cheese, other species of Penicillium, such as P. carneum and P. paneum, can produce mycotoxins. These toxins are harmful to humans and can lead to reduced immune function, digestive problems, and even cancer. Therefore, it is important to differentiate between the different species of Penicillium and ensure that only safe strains are used in food production.

The mould in blue cheese is from the same family of spores used to make penicillin
Blue cheese is made using a type of mold called Penicillium, specifically Penicillium roqueforti, which is a type of fungus. This is the same family of spores used to make the antibiotic penicillin. The blue veins in the cheese are caused by the growth of this mold.
While it may seem counterintuitive to eat moldy food, the Penicillium mold used in blue cheese production is safe for human consumption and is not harmful. In fact, it is this mold that gives blue cheese its distinctive flavor and aroma. The mold breaks down fat through a process called lipolysis, which leads to the formation of fatty acids. Penicillium roqueforti then converts these fatty acids into ketones, which give blue cheese its unique smell and flavor.
It is important to note that not all molds are the same. While blue cheese is made with mold and is safe to eat, other types of mold can be dangerous. Certain strains of mold produce mycotoxins, which are toxic to humans and can lead to health issues such as reduced immune function, digestive problems, and even cancer. Therefore, it is crucial to practice proper food safety and storage when it comes to blue cheese and other mold-prone foods.
Blue cheese should be stored properly to prevent the growth of harmful mold. It is recommended to wrap blue cheese tightly and store it in the refrigerator, where it can last for 3-4 weeks. Freezing blue cheese can also extend its shelf life, although it may alter its texture and appearance slightly. If you notice any signs of spoilage, such as fuzzy white, green, pink, or grey spots, it is best to discard the cheese immediately.
In summary, the mold in blue cheese, Penicillium roqueforti, is from the same family of spores used to make penicillin. This mold is safe for human consumption and gives blue cheese its unique characteristics. However, proper food safety practices and storage methods are essential to prevent the growth of harmful molds that can be dangerous to human health.

Blue cheese can go bad if it's not stored properly
Like other types of cheese, blue cheese can go bad if it's not stored properly. It's important to practice basic food safety and store blue cheese correctly to prevent spoilage and the growth of harmful moulds.
Blue cheese is made using mould cultures of Penicillium, specifically Penicillium roqueforti, a type of fungus. The mould in blue cheese is responsible for its distinctive taste and aroma, colour, and appearance. The blue veins in the cheese are caused by the growth of Penicillium roqueforti, which breaks down fatty acids and converts them into ketones, resulting in a unique flavour and smell.
While the mould in blue cheese is safe for human consumption, other types of mould can develop if the cheese is not stored correctly. These moulds can produce mycotoxins, which are toxic to humans and can lead to health issues such as reduced immune function, digestive problems, and in some cases, cancer.
To prevent blue cheese from going bad, it should be stored in the refrigerator, tightly wrapped. Parchment paper and beeswax paper are recommended for wrapping as they allow the cheese to breathe, preventing moisture buildup that can foster the growth of harmful moulds. Properly stored blue cheese can last 3-4 weeks in the refrigerator.
It's important to regularly inspect blue cheese for signs of spoilage. Fuzzy white, green, pink, or grey spots on the surface indicate that the cheese has gone bad and should be discarded. Additionally, blue cheese should not be packed in a vacuum seal as it can alter the metabolism of the Penicillium roqueforti mould, resulting in unusual flavours and colours.

The mould in blue cheese is safe to eat, but mould that builds up naturally on food is not
Blue cheese is made with mould, specifically Penicillium roqueforti, a type of fungus and microorganism. This is the same family of spores used to make penicillin. The mould is what gives blue cheese its distinctive colour, smell, and flavour. The mould breaks down fatty acids, converting them into ketones, which give blue cheese its unique smell and flavour.
While mould on most foods is a sign of spoilage and can be harmful, the mould in blue cheese is safe to eat. The mould in blue cheese is chosen for its taste and does not produce toxins. The mould in blue cheese is nontoxic and even beneficial, preventing harmful moulds from attacking the cheese.
However, blue cheese can still go bad, so it is important to practice proper food safety and storage. If you see fuzzy white, green, pink, or grey spots on blue cheese, it has likely gone bad and should be discarded.
While the mould in blue cheese is safe to consume, mould that builds up naturally on food is not. Just because someone may have tried mouldy food and not gotten sick does not mean it is safe. It simply means their gut has a good defence or they got lucky.

Some types of mould produce mycotoxins, which are toxic to humans
Blue cheese is made using cultures of a type of mould called Penicillium, which comes from the same family as the mould used to make the antibiotic medicine penicillin. The mould in blue cheese is responsible for its distinctive taste and aroma.
However, not all mould is the same. Some types of mould produce mycotoxins, which are toxic to humans. These mould spores can grow on foods due to spoilage, and they are typically fuzzy and white, green, black, blue, or grey. Mycotoxins can lead to reduced immune function, digestive problems, and even cancer. Therefore, it is important to buy quality cheese and practice basic food safety by storing blue cheese properly.
The mould in blue cheese, specifically Penicillium roqueforti, does not produce toxins and is considered safe to consume. Blue cheese gets its name from the blue veins caused by the growth of this mould. The distinct flavour of blue cheese is attributed to the breakdown of fat through a process called lipolysis, which leads to the formation of fatty acids. Penicillium roqueforti then converts these fatty acids into a group of molecules called ketones, giving blue cheese its unique smell and flavour.
While blue cheese is made with mould and is safe to eat, it can still go bad if not stored properly. It is important to store blue cheese tightly wrapped in the refrigerator, and it can last 3-4 weeks when properly refrigerated. Freezing blue cheese can also help extend its shelf life, although it may slightly alter its texture and appearance. If you notice any signs of spoilage, such as fuzzy white, green, pink, or grey spots, it is best to discard the cheese immediately.
