The discovery of mould on cheese can be distressing, but it is not always cause for alarm. Mould is an integral part of the cheesemaking process, and most cheeses owe their distinct deliciousness and texture to the microbiological alchemy that occurs when mould, bacteria, and other microorganisms feast on the proteins and sugars present in milk. Harder, aged cheeses, like Parmesan, can usually be salvaged by scraping or cutting away the mould, whereas softer cheeses are more likely to be contaminated and should be discarded.

Parmesan cheese is a hard, salty cheese, so mold will usually only penetrate the surface
Parmesan is a hard and salty cheese, and as such, mold will usually only penetrate the surface. This means that if you discover mold on your Parmesan, you can simply cut or scrape it away, and the remaining cheese will be safe to eat. However, it is important to assess the type of mold present before consuming the cheese. If the mold is white, fuzzy, and tinged with green, it is generally safe to remove it and consume the cheese. On the other hand, black or gray mold is less desirable, and a larger portion of the cheese should be discarded to ensure no impacted cheese remains. Additionally, if the cheese smells of ammonia or is both moldy and wet, it should be thrown away.
The likelihood and rate of mold growth on cheese depend on its moisture content. Microorganisms, including mold, thrive in wet environments and are less active in dry ones. Therefore, hard and salty cheeses like Parmesan are less susceptible to mold growth compared to softer cheeses. Semi-soft cheeses, such as Havarti or mild cheddar, are more prone to mold penetration, while extremely wet, fresh cheeses like mozzarella, ricotta, cream cheese, or chèvre should be discarded if mold is visible, as the mold has likely affected the flavor and texture.
While mold on hard cheeses like Parmesan can usually be safely scraped off, it is essential to practice proper storage methods to prevent mold growth. Proper storage can increase the shelf life of cheese and reduce the risk of mold contamination. Storing cheese in airtight containers or wrapping it in wax or special cheese paper can help maintain its freshness and delay mold growth. Additionally, storing cheese in the refrigerator at the proper temperature can further inhibit mold development.
It is worth noting that while mold on Parmesan cheese is typically surface-level, it can still impact the flavor and texture of the surrounding cheese. Even if the mold is scraped off, the affected area may still taste unpleasant. In such cases, it is advisable to cut away a larger portion of the cheese to ensure the desired flavor and texture are preserved. Furthermore, while mold is a natural part of the cheesemaking process, some individuals may be more sensitive to its presence. If you are concerned about the potential effects of consuming moldy cheese, it is always recommended to err on the side of caution and discard the cheese entirely.
In summary, Parmesan cheese is a hard and salty variety, which makes it less susceptible to mold penetration. While surface mold can often be safely scraped away, it is crucial to identify the type of mold, practice proper storage methods, and consider the potential impact on the cheese's flavor and texture. Ultimately, the decision to consume moldy cheese carries a degree of risk, and it is up to the individual to weigh the benefits against the potential drawbacks.

It is safe to scrape off the mold from Parmesan cheese and consume the rest
It is generally safe to scrape off the mold from hard cheeses like Parmesan and consume the rest of the cheese. Mold is an integral part of the cheesemaking process, and most molds are not harmful to human health. However, it is important to note that mold can negatively impact the flavor and texture of the cheese, so it may not taste as intended.
The penetrability of mold roots depends on the moisture content of the cheese. Hard, dry cheeses like Parmesan are less susceptible to mold growth, as microorganisms thrive in wet environments. This means that mold roots will likely remain on the surface of Parmesan cheese, and scraping off the mold will render the rest of the cheese safe to consume.
On the other hand, soft and semi-soft cheeses, such as Havarti, mild cheddar, mozzarella, ricotta, cream cheese, and chèvre, are more susceptible to mold growth. In these cases, it is recommended to discard the entire product if mold is visible, as the roots may have penetrated deeper into the cheese, altering its flavor and texture.
It is worth noting that while most molds are not harmful, there are rare types of mold that can present health concerns, such as the dark black-gray mold Aspergillus niger. Therefore, it is always important to inspect the cheese for any signs of undesirable mold before consuming, even after scraping off the visible mold. Additionally, proper storage practices should be followed to prevent excessive mold growth.
In summary, it is generally safe to scrape off the mold from Parmesan cheese and consume the rest. However, it is crucial to consider the type of cheese, the extent of mold growth, and the potential impact on flavor and texture. Proper food handling practices should always be maintained to ensure the safety and quality of the cheese.

Black, grey, or fluorescent mold on Parmesan cheese should be discarded
Mouldy cheese is not toxic, and you are unlikely to get sick from eating it. However, mould can negatively impact the flavour and texture of the cheese. Therefore, it is important to know how to handle mould on your cheese to ensure you don't waste any delicious morsels.
Hard, aged cheeses like Parmesan are less susceptible to mould because they are dry and salty. The mould roots will barely penetrate the surface, so it is safe to scrape off the mould and eat the rest of the cheese. However, if you see black, grey, or fluorescent mould on your Parmesan cheese, it is best to discard it. These types of mould are less desirable and may indicate that the cheese has been impacted.
Soft cheeses, such as Brie, Port Salut, ricotta, mascarpone, and chèvre, are more susceptible to mould because they are damp. If you see mould on a soft cheese, it is best to discard the entire cheese because the mould has likely penetrated deep into the cheese.
To avoid mouldy cheese, buy long-aged, hard cheeses like Parmesan, pecorino, older Cheddars, and aged Gouda. Cheeses that age for 18 months or longer are the least likely to mould. Additionally, proper storage can help increase the shelf life of your cheese.
In summary, black, grey, or fluorescent mould on Parmesan cheese should be discarded. For other types of mould on hard cheeses, simply scrape off the mould and enjoy the rest of your cheese.

Soft cheeses with mold, like mozzarella or ricotta, should be thrown away
When it comes to mouldy cheese, the general rule is that hard cheeses like Parmesan, Swiss, or Cheddar can usually be salvaged by cutting away the mouldy area. However, soft cheeses with mould, like mozzarella, ricotta, cream cheese, or chèvre, should be thrown away.
Soft cheeses are more susceptible to mould growth because they have a higher moisture content, providing an ideal environment for microorganisms like mould to thrive. When mould appears on soft cheeses, it indicates spoilage, and the spores can quickly contaminate the entire product. While mould on hard cheeses may be superficial, mould on soft cheeses is likely to penetrate deeper, affecting the flavour and texture of the cheese.
Fresh soft cheeses like mozzarella, ricotta, and queso fresco are meant to be consumed shortly after they are made. They have a high moisture content, providing the perfect environment for mould to grow and spread. When mould appears on these cheeses, it's best to discard them entirely.
Mozzarella, for instance, is an extremely wet, fresh cheese. When mould appears on mozzarella, it is recommended to throw it away. While it may not be toxic, the mould will likely have altered the flavour of the cheese, and not in a desirable way. The same principle applies to ricotta, another fresh, moist cheese. Mould will quickly spread throughout ricotta, impacting its taste and texture, so it's best to discard it rather than attempting to salvage it.
In summary, while it may be tempting to cut away the mouldy parts of soft cheeses like mozzarella or ricotta, it's generally safer to discard them entirely. Mould can quickly spread throughout these moist cheeses, affecting their flavour and texture, and potentially carrying harmful bacteria. To prevent mould growth, proper storage is essential, and opting for long-aged, hard cheeses can reduce the likelihood of encountering mouldy cheese.

Mold is an integral part of the cheesemaking process
The presence of mold is an integral part of the cheesemaking process. While mold indicates spoilage in most foods, this is not always the case with cheese. The type of mold and the type of cheese determine whether the mold is safe to consume.
Cheese is unique in its makeup as it requires certain types of mold to produce certain cheeses. The differences in a cheese's appearance, taste, and texture depend on the type of milk, bacteria present, length of aging, and processing methods. Mold is a fungus that grows on cheeses either intentionally or unintentionally. Natural or healthy mold is required to make particular kinds of cheeses during their production process. This type of mold is used to produce the white mold around bloomy-rind cheeses, aiding in the ripening process and adding a variety of subtle flavors.
On the other hand, spoiled mold typically suggests spoilage because it changes the appearance, smell, and taste of the food. This type of mold usually appears as a fuzzy green, black, blue, white, or grey color. It is important to note that fresh soft cheeses like ricotta, mascarpone, and chèvre should be discarded if mold appears, as the damp environment allows mold to penetrate deeper into the cheese, altering its flavor.
For semi-soft and harder cheeses, the mold may not have penetrated as deeply, and cutting away a portion of the cheese around the mold may be sufficient to salvage the rest. The guideline for hard cheeses is to cut away at least 1/2 inch (1 centimeter) of cheese around and below the moldy section. However, it is important to note that the remaining cheese may still have an altered flavor due to the presence of mold.
In summary, while mold is an integral part of the cheesemaking process, it is important to distinguish between natural and spoiled mold to ensure the safety and quality of the cheese.
