Blue cheese is made using mould, specifically 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 still go bad if it is not stored properly, and consuming spoiled blue cheese can lead to food poisoning. Therefore, it is important to practice food safety and store blue cheese properly to prevent negative side effects.

Blue cheese gets its distinctive colour, flavour, and texture from mould
Blue cheese is a type of cheese that gets its distinctive colour, flavour, and texture from mould. The mould in blue cheese is safe to eat. It comes from the same spores that penicillin is made from. Penicillin is an antibiotic medicine.
The blue veins in blue cheese are caused by the growth of the mould Penicillium roqueforti, a type of fungus. This mould is added to the cheese curds after the whey has been drained, and the curds have been shaped into wheels. The cheese is then left to age for 2–3 months. During this time, the cheese is pierced to make holes, allowing oxygen in and encouraging the mould to spread and create the unique vein-like patterns throughout the cheese.
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, particularly near where the amino acids are most active—the grey, blue veins. In addition, 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, sharp flavour, and odd smell.
While some types of mould produce compounds called mycotoxins, which are toxic to humans, the varieties of Penicillium used to produce blue cheese do not produce toxins and are considered safe to consume. However, blue cheese can still go bad if it is not stored properly. It is important to wrap it tightly and store it in the refrigerator, where it can last 3–4 weeks. Freezing blue cheese can also extend its shelf life, although this may slightly alter its texture and appearance.

The mould in blue cheese is from the same family of spores used to make penicillin
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. The mould in blue cheese is from the same family of spores used to make penicillin.
The mould on blue cheese, such as Roquefort, comes from the controlled application of Penicillium roqueforti or Penicillium glaucum. These moulds are selected for human consumption and do not produce toxins harmful to humans. The mould greatly accelerates biochemical processes, creating the unique look, texture, and taste of blue cheese.
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, particularly near where the amino acids are most active—the grey, blue veins. In addition, 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.
The process of making blue cheese involves adding mould cultures to enhance the dairy product's sharp and savoury flavour, as well as giving it its instantly recognisable appearance. The mould is added 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 for consumption.
While blue cheese is made with mould and is safe to eat, it can still go bad if not properly stored. It is important to wrap blue cheese tightly and store it in the refrigerator. Proper storage can help prevent negative side effects and ensure the safe consumption of blue cheese.

Blue cheese can go bad if it's not stored properly
Blue cheese is made using a type of mold called Penicillium, which is responsible for its distinct taste, smell, and appearance. While the mold in blue cheese is safe to consume, the cheese can still go bad if it's not stored properly.
To prevent food poisoning, it is important to practice basic food safety and store blue cheese properly. Blue cheese should be tightly wrapped and refrigerated, and it should be discarded if there are any changes in its appearance or smell. If stored properly, blue cheese can last 3–4 weeks in the refrigerator.
Freezing blue cheese can also help extend its shelf life. Although freezing may slightly alter its texture and appearance, it remains safe to consume indefinitely when frozen.
It is important to note that not all molds are the same. Some types of mold produce compounds called mycotoxins, which are toxic and harmful to humans. These molds typically grow on food that has been left out for many days. The mold used to make blue cheese, however, does not produce toxins and is safe for human consumption.
In summary, blue cheese can go bad if it's not stored properly, and it's important to follow food safety practices to prevent negative side effects and enjoy blue cheese safely.

Blue cheese is made using mould cultures, which are added to enhance its flavour and appearance
The mould in blue cheese comes from the same spores that Penicillin is made from. Certain types of mould produce compounds called mycotoxins, which are toxic to humans. However, the mould in blue cheese, called Penicillium, does not produce these toxins and is safe to consume. Penicillium roqueforti, for example, is responsible for the blue streaks in Roquefort cheese. It produces enzymes that release amino acids, which quickly break down the cheese's proteins (casein). This process, called proteolysis, makes the cheese creamy, particularly near where the amino acids are most active—the grey, blue veins. Penicillium roqueforti also triggers another biochemical event called lipolysis, which creates free fatty acids and releases methyl ketone. This gives the cheese its distinct blue look, odd smell, and sharp flavour.
Blue cheese is made by first draining the whey and pressing the curds into wheel shapes. Then, the mould is added, and the cheese is set aside to mature. During this aging process, the cheese is pierced to make holes, which allow oxygen in and encourage the mould to spread along the air holes, creating the unique vein-like patterns throughout the cheese.
While blue cheese is made with mould, it can still go bad if not stored properly. It is important to practice basic food safety and store blue cheese properly to prevent negative side effects. If there are any changes in its appearance or smell, it should be discarded. Consuming spoiled blue cheese can cause food poisoning and increase exposure to harmful mycotoxins.

Consuming spoiled blue cheese can cause food poisoning
Blue cheese is made using a type of mold called Penicillium, which is responsible for its distinct taste, smell, and appearance. While the mold in blue cheese is generally safe to consume, consuming spoiled blue cheese can cause food poisoning and lead to adverse health effects.
Penicillium roqueforti, the mold commonly used in blue cheese production, does not produce toxins harmful to humans. However, if blue cheese is not properly stored and handled, it can spoil and become contaminated with other types of mold or bacteria. These contaminants can produce mycotoxins, which are toxic compounds that can cause food poisoning and pose serious health risks.
Consuming spoiled blue cheese can lead to symptoms such as nausea, vomiting, diarrhea, and stomach cramps. Mycotoxins can also suppress immune function, cause digestive distress, and potentially contribute to cancer. To prevent these negative side effects, it is crucial to practice proper food safety and storage when handling blue cheese.
Blue cheese should be tightly wrapped and refrigerated, with a typical shelf life of 3–4 weeks when properly stored. Freezing blue cheese can further extend its shelf life, although it may slightly alter its texture and appearance. It is important to check the use-by date and inspect the cheese for any changes in appearance or smell before consumption. If there are signs of spoilage or mold other than the intended blue veins, the cheese should be discarded.
In summary, while the mold in blue cheese is generally safe, consuming spoiled blue cheese can cause food poisoning and increase exposure to harmful mycotoxins. Proper storage, handling, and adherence to use-by dates are essential to minimize the risk of foodborne illnesses associated with spoiled blue cheese.
