Blue cheese is made with mold—specifically, Penicillium roqueforti, a type of fungus that gives the cheese its distinctive color and flavor. While the presence of mold itself is not necessarily a cause for concern, blue cheese can go bad if it's not stored properly. If you notice any signs of spoilage, such as fuzzy white, green, pink, grey, black spots, or a slimy texture, it's best to discard the cheese. While most molds are harmless, certain strains can produce mycotoxins, which are toxic to humans and can lead to health issues. Therefore, it's important to practice basic food safety and properly store blue cheese to prevent spoilage and potential health risks.

Blue cheese gets its colour and flavour from the fungus Penicillium roqueforti
Blue cheese is a type of cheese that contains mould. The mould in blue cheese is called Penicillium, specifically Penicillium roqueforti, a type of fungus. This fungus is responsible for the characteristic blue veins in blue cheese, which occur when the fungus grows and spreads throughout the cheese.
Penicillium roqueforti is added to the cheese after the curds have been drained and shaped into wheels. The cheese is then left to age for 2-3 months. During this time, the fungus grows and spreads throughout the cheese, producing enzymes that break down fat through a process called lipolysis. This leads to the formation of fatty acids and ketones, which give blue cheese its distinctive smell and flavour. The specific smell of the cheese depends on the type of ketone produced by the mould.
While it may seem concerning to eat mouldy cheese, the type of mould in blue cheese is safe for human consumption. Unlike other types of mould, Penicillium roqueforti does not produce toxins and is not harmful to humans. This is because the mould is carefully controlled during the cheesemaking process, and the specific species of mould used is selected for its safety.
However, it is important to note that blue cheese can still go bad if it is not stored properly. If you notice any signs of spoilage, such as fuzzy white, green, pink, or grey spots on the surface of the cheese, it should be discarded immediately. Proper storage of blue cheese involves keeping it tightly wrapped 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.

Penicillium roqueforti does not produce toxins and is safe to consume
Blue cheese is a type of cheese made using cultures of Penicillium, a type of mold. While moldy cheese, in general, should be discarded, blue cheese is made using mold and is safe to consume. However, blue cheese can go bad if not stored properly, and it is important to practice basic food safety and store it tightly wrapped in the refrigerator.
Penicillium roqueforti is a type of mold that is used to make blue cheese. It is responsible for giving blue cheese its distinctive color, smell, and flavor. This mold does not produce toxins and is safe for human consumption. The mold breaks down the cheese's proteins through a process called proteolysis, making the cheese creamy. It also triggers lipolysis, which leads to the creation of free fatty acids and the release of methyl ketone, giving the cheese its blue appearance, sharp flavor, and unique smell.
While blue cheese is made with mold and is safe to eat, other types of mold that may grow on blue cheese can be harmful. It is important to check for any signs of spoilage, such as fuzzy white, green, pink, grey, or black spots, which indicate that the cheese has gone bad and should be discarded. Good blue cheese should have greenish-blue veins and a body that is cream to white in color. It should also have a pungent smell, which is a sign of the breakdown of fat and the formation of fatty acids that contribute to its unique flavor.
It is worth noting that some people may have different levels of tolerance to moldy cheese. While most blue cheese is safe to consume due to the controlled use of Penicillium roqueforti, it is always advisable to practice good food safety habits and properly store and handle cheese to minimize the risk of spoilage and potential health hazards.
In summary, Penicillium roqueforti, the mold used to make blue cheese, does not produce toxins and is generally safe for human consumption. However, proper storage and handling of blue cheese are crucial to prevent spoilage and the growth of harmful mold or bacteria.

Blue cheese can go bad if not stored properly
Blue cheese is made using cultures of Penicillium, a type of mold. Certain types of mold produce compounds called mycotoxins, which are toxic to humans. However, the varieties of Penicillium used to produce blue cheese do not produce toxins and are considered safe to consume.
Blue cheese can, however, go bad if it is not stored properly. If you notice any signs of spoilage on your blue cheese, you should discard it immediately. In particular, fuzzy white, green, pink, or grey spots growing on the surface of blue cheese may indicate that it has gone bad. Cheese that is slimy or feels tough and dry has likely spoiled. As with most foods, the easiest way to tell if blue cheese is safe to eat is to use your senses and basic judgment. If it smells like ammonia, it's probably best to throw it away.
To prevent blue cheese from going bad, it is important to store it properly. Blue cheese should be tightly wrapped and refrigerated. If stored properly, it can last 3–4 weeks in the refrigerator. You can also freeze blue cheese to extend its shelf life. Although freezing blue cheese may slightly alter its texture and appearance, it remains safe to consume indefinitely when frozen.
It is also important to note that not all mold is created equal. While the presence of mold on blue cheese is generally not a cause for concern, some types of mold can be harmful. Aspergillus niger, for example, is a dark black-gray mold that can be harmful. Therefore, it is important to practice basic food safety and handle blue cheese with care.

Spoiled blue cheese can cause food poisoning, stomach cramps, vomiting, and diarrhea.
If you notice that your blue cheese is spoiled, you should throw it away. While the presence of mold itself is not necessarily a cause for concern, it is important to practice basic food safety and store blue cheese properly. Check the use-by date and make sure you use the cheese by then.
It is worth noting that not all mold is created equal. Some types of mold are safe to consume and are even integral to the flavor and texture of certain cheeses. For example, the thick white rind on the outside of a wheel of brie is a type of mold called Penicillium candidum. This mold is safe to consume and gives brie its savory, mushroomy flavor.

However, blue cheese can still go bad, so it's important to practice basic food safety and store blue cheese properly. If you notice pink spots on your blue cheese, it is an indication that your blue cheese has gone bad and you should discard it immediately. According to Carie Wagner, one of Wisconsin's elite master cheesemakers, good blue cheese should have greenish-blue veins and a body that's cream to white in color. It should also be pungent, and if the smell that first hits you when you uncover the cheese is comparable to ammonia, that's not a bad thing.
Pink spots on blue cheese indicate bacterial growth, which could be non-toxic lactic acid bacteria or even E. coli. While not all bacteria are toxic, it is best to avoid consuming blue cheese with pink spots. If you notice any signs of spoilage on your blue cheese, you should discard it immediately.
To prevent blue cheese from spoiling, it is important to store it properly. Blue cheese should be tightly wrapped and refrigerated. If stored properly, it can last 3–4 weeks in the refrigerator. You can also freeze blue cheese to extend its shelf life. Although freezing may slightly alter its texture and appearance, it remains safe to consume.
