Blue cheese is made using mould, specifically Penicillium roqueforti, a variety of mould that is in the same family as the one that the antibiotic penicillin is made from. This mould is responsible for blue cheese's distinct taste, smell and appearance. But does blue cheese taste like mould? While the mould in blue cheese is safe to eat, it can still go bad and it's important to practice basic food safety. Food spoilage is often caused by mould, and some types can produce harmful toxins. So, while blue cheese is made using mould, it shouldn't taste like mould, and if it does, it's probably gone bad.

Blue cheese is made using a type of mould called Penicillium
The mould spores accelerate the biochemical processes that give blue cheese its unique characteristics. Penicillium roqueforti, for example, produces enzymes that break down the cheese's proteins (casein), a process called proteolysis. This process makes the cheese creamy, especially near the blue veins where the amino acids are most active. Penicillium roqueforti also triggers another process called lipolysis, which leads to the creation of free fatty acids and the release of methyl ketone, giving the cheese its distinct blue colour, sharp smell, and flavour.
To make blue cheese, cheesemakers encourage the growth of these specific moulds. Traditionally, this was done by leaving rye bread in damp, dark caves for several weeks to grow mould, then grinding it into a dust that was sprinkled onto fresh cheese curds. Today, most blue cheese is made in labs and hygienic production facilities, where conditions are controlled to prevent the growth of dangerous moulds, fungi, and bacteria.
While blue cheese is made with mould and is safe to consume, it can still spoil. Basic food safety practices and proper storage are important to prevent spoilage and the growth of harmful moulds. If there are any changes in the appearance or smell of blue cheese, it should be discarded, as consuming spoiled cheese can lead to food poisoning and exposure to harmful toxins.

Penicillium mould is safe to consume and does not produce toxins
Blue cheese is made using a type of mould called Penicillium, which is responsible for its distinct taste, smell, and appearance. While mould is often a sign of food spoilage, the types of Penicillium used to produce blue cheese are safe to consume and do not produce toxins.
Penicillium mould is typically non-pathogenic, meaning it does not cause disease. However, it can trigger allergic reactions or respiratory problems in some individuals, especially those with weak or compromised immune systems. It is important to note that not all species of Penicillium are safe. Some species of Penicillium mould can produce toxic compounds called mycotoxins, which can be harmful to humans if ingested or inhaled over a long period. These mycotoxins can cause a range of adverse health effects, including organ damage and cancer.
The types of Penicillium mould used in cheese production, specifically Penicillium roqueforti and Penicillium glaucum, are safe for human consumption and do not produce toxins. These moulds are in the same family as the mould that produces penicillin, one of the most important antibiotics in medicine. When Penicillium mould comes into contact with cheese, it triggers biochemical events that create the unique look, texture, and taste of blue cheese.
To ensure food safety, it is important to store blue cheese properly and practise basic food safety practices. While blue cheese can still go bad, proper storage can prevent spoilage and the growth of dangerous moulds, fungi, or bacteria. It is also important to discard blue cheese if there are any changes in its appearance or smell, as consuming spoiled blue cheese can cause food poisoning.

Food spoilage is often caused by mould, which can produce harmful toxins
Mould produces spores that give it its colour, which is typically green, white, black, or grey. It also has a distinctive taste and smell. While some types of mould can produce harmful toxins, other types are used to produce certain foods, including some cheeses. For example, Penicillium roqueforti is used to make blue cheese, but it will cause spoilage if it grows in fresh or grated cheese.
The mould in blue cheese is safe to eat. It comes from the same spores that penicillin is made from. Penicillium roqueforti does not produce toxins by itself and is not dangerous to humans. It gives blue cheese its distinct taste, smell, and appearance. However, blue cheese can still go bad, so it is important to practice basic food safety and store it properly. Consuming spoiled blue cheese can cause food poisoning and increase exposure to harmful mycotoxins.
There are several methods to prevent food spoilage, including pickling, freezing, drying, salting, curing, canning, refrigeration, and the use of preservatives. Food spoilage can also be detected using various methods, such as biosensors, gas sensors, and colorimetric analysis.

Blue cheese can go bad, so it's important to practice basic food safety
Blue cheese is made using a type of mould called Penicillium, which is responsible for its distinct taste, smell, and appearance. While the types of Penicillium used to produce blue cheese are safe to consume and do not produce mycotoxins, blue cheese can still go bad. Therefore, it is important to practice basic food safety and store blue cheese properly.
Mould is often a sign of food spoilage, and some types of mould can produce harmful toxins. While the mould in blue cheese is safe to eat, consuming spoiled blue cheese can cause food poisoning and increase exposure to harmful mycotoxins. To prevent these negative side effects, it is important to store blue cheese properly and practice food safety.
Proper storage of blue cheese involves keeping it in a cool, dark, and dry place. Blue cheese should be wrapped or stored in an airtight container to prevent moisture buildup and mould growth. It is also important to keep blue cheese separate from other cheeses, as the mould can spread to other cheeses.
In addition to proper storage, it is important to regularly check blue cheese for any signs of spoilage. Blue cheese should be discarded if there are any changes in its appearance, smell, or texture. Signs of spoilage may include the growth of mould in different colours or textures than the original blue veins, the presence of an off-putting smell, or the cheese becoming slimy or discoloured.
Practicing basic food safety and proper storage of blue cheese can help prevent food poisoning and other negative side effects associated with consuming spoiled cheese. By following these simple guidelines, you can safely enjoy blue cheese and its unique flavour and texture.

The mould in blue cheese creates its distinct blue look, smell, and sharp flavour
The mould in blue cheese, which comes from the same spores that Penicillin is made from, creates its distinct blue look, smell, and sharp flavour. Blue cheese is made using a type of mould called Penicillium, which is responsible for its distinct taste, smell, and appearance. Penicillium roqueforti produces enzymes that release amino acids, which quickly break down the cheese's proteins (casein). This process, called proteolysis, makes the cheese creamy, especially near where the amino acids are most active—the grey-blue veins. Penicillium roqueforti also triggers another biochemical event called lipolysis, which leads to the creation of free fatty acids and the release of methyl ketone. This gives the cheese its distinct blue look, odd smell, and sharp flavour.
While mould is often a sign of food spoilage, the types of Penicillium used to produce blue cheese do not produce mycotoxins and are considered safe to consume. However, blue cheese can still go bad, so it is important to practice basic food safety and store blue cheese properly. Consuming spoiled blue cheese can cause food poisoning and increase exposure to harmful mycotoxins.
Most moulds that are a part of the cheesemaking process are integral to the flavour and texture of the finished cheese. However, mould can negatively impact the flavour and texture of the cheese it is growing on, and at the very least, will make it taste pretty different from how it was supposed to.
