Cooking can kill mold, as heat can disrupt the viability of mold by preventing it from growing or spreading. However, it is important to note that not all molds are eliminated by heat, and the toxins produced by certain molds may remain even after cooking. While some molds on hard cheeses can be scrubbed off and consumed, it is crucial to recognize and differentiate between harmless and harmful mold. Soft cheeses with mold should be discarded immediately, as the roots of the mold can penetrate deeper into the cheese, altering its flavor and potentially causing health risks.

Cooking can kill some mould on cheese
Mould is a type of fungus that thrives in moist environments and is transported through air, water, and insects. It can grow on all types of food, including cheese, and typically indicates that the food should be discarded. However, in the case of hard cheeses, such as Parmesan or aged cheddar, it may be possible to scrub off or cut off the mouldy parts and consume the rest of the cheese.
Soft cheeses, such as mozzarella, ricotta, cream cheese, or chèvre, should be discarded if mould is present, as the roots of the mould are likely to have penetrated deeper into the cheese. Additionally, any utensils or surfaces that came into contact with the mouldy cheese should be cleaned and sanitised to prevent further mould growth.
It is worth noting that some cheeses, such as blue cheese and Brie, are meant to have mould in them, and these moulds are safe to consume. These moulds are introduced during the cheesemaking process and help develop the unique flavours and textures of the cheese. However, if mould appears on these cheeses outside of the intended areas, it is best to discard the cheese.
In summary, while cooking can kill some mould on cheese, it is not a reliable method for ensuring the safety of the cheese. It is important to consider the type of cheese, the extent of mould growth, and whether the cheese is meant to have mould in it. Proper food handling and storage practices, such as refrigeration and consuming food within recommended time frames, can help prevent mould growth and reduce the risk of foodborne illnesses.

Soft cheese with mould should be discarded
While mouldy cheese is generally not toxic, it can negatively impact flavour and texture. Therefore, it is important to differentiate between harmless and harmful mould. Soft cheeses like ricotta, mascarpone, and chèvre are highly susceptible to mould because of their damp environment. The mould will likely have penetrated deep into the cheese, altering its flavour. Therefore, it is recommended to discard these cheeses entirely if they become mouldy.
On the other hand, harder cheeses like Parmesan, pecorino, and aged cheddars can be salvaged by cutting off the mouldy parts. For these hard cheeses, it is recommended to cut off at least an inch around and below the mould spot and then eat it. Semi-soft cheeses like mozzarella can also be eaten after cutting off the mould.
To prevent mould growth, proper storage and timely consumption of cheese are crucial. Cheese can be stored in special cheese paper, parchment paper, or plastic wrap. It should be labelled with the type of cheese and the purchase date. Store cheese in the refrigerator or freezer to keep it cold, which helps to prevent mould growth.
While heat can kill mould, it is important to note that not all moulds are killed by heat, and the toxins produced by certain moulds may remain. Therefore, it is generally safer to discard mouldy soft cheeses rather than attempting to cook them.

Hard cheese with mould can be cut off
While mould on cheese will rarely kill you, it can negatively impact flavour and texture. If you spot mould on hard cheese, you can simply cut it off—about an inch around and below the mould spot if you want to be extra careful—and then grate the rest as usual. This is because microorganisms that cause mould thrive in wet environments and are less active in dry ones, so they will barely be able to penetrate the surface of a hard, salty cheese.
However, it's important to differentiate between harmless and harmful mould. While some moulds on hard cheeses can be scrubbed off, mouldy soft cheese should be discarded immediately. Fruits with a softer peel, such as oranges or bananas, should also be thrown away as the mould may have penetrated the flesh of the fruit inside.
If you're wondering whether cooking can kill mould, the answer is yes, heat can disrupt the viability of mould and prevent it from growing or spreading. However, it's important to note that not all moulds are killed by heat, and the toxins produced by certain moulds may remain. Always clean and sanitise your kitchen after cooking mouldy food to prevent future mould growth.
Some people may feel uncomfortable with the idea of cutting mould off cheese and then consuming it. In these cases, it's best to trust your instincts and throw the cheese away.

Mould on cheese can negatively impact flavour and texture
Mould on cheese can negatively impact its flavour and texture. While mould is an integral part of the cheesemaking process, the type of mould that grows on cheese that has been forgotten in the fridge will likely compromise its flavour and texture.
Mould grows roots, and the fuzzy stuff you see growing on the exterior might have little tendrils that go deep. How far these roots penetrate depends on how dry or moist the cheese is. Microorganisms thrive in wet environments and are less active in dry ones. This means that mould roots will barely penetrate the surface of hard, salty cheeses like Parmesan or a crumbly, long-aged cheddar. However, they will get deeper into a semisoft cheese like Havarti or a mild cheddar. As for extremely wet, fresh cheeses like mozzarella, ricotta, cream cheese, or chèvre, the mould will most definitely have changed the flavour of the cheese, and probably not for the better.
It is important to differentiate between harmless and harmful mould. While some moulds on hard cheeses can be scrubbed off, mouldy soft cheese should be discarded immediately. Fresh soft cheeses like ricotta, mascarpone, chèvre, and similar varieties should be discarded since the damp environment means that the mould has likely penetrated deep into the cheese. While not toxic, it will have negatively impacted the flavour. Soft cheeses like Brie or Port Salut should have about a quarter of an inch cut away from any surface where mould is visible. Harder, aged cheeses, like aged Cheddar or Parmesan, can have the mould scraped away. With white, fuzzy mould, tinged with green, the flavour effect is minimal, and the mould can be safely cut away without incident.
While heat can eliminate mould growth on various foods, it is not advisable to simply cook mouldy food to kill the mould. Although heat can kill mould, the toxins produced by certain moulds might remain. Therefore, it is important to assess the type of cheese and the mould that has grown on it before deciding whether to cut off the mould or discard the cheese entirely.

Not all mould is killed by heat
While heat can kill mould by disrupting its viability, not all mould is killed by heat. Certain types of mould produce mycotoxins, which are poisonous substances that can make you very sick or even kill you. Therefore, it is important to differentiate between harmless and harmful mould. Soft cheeses that are mouldy should be discarded immediately, whereas mould on hard cheeses can be scrubbed off or cut away. However, it is recommended to cut off about an inch around and below the mould spot to be rigorous.
Mould is a type of fungus that thrives in moist areas and is transported through water, air, or insects. It grows roots and spreads, with the potential to penetrate deep into the cheese. The softer the cheese, the easier it is for mould to spread and infect the cheese. Therefore, extremely wet, fresh cheeses like mozzarella, ricotta, cream cheese, or chèvre should be discarded if mould is visible.
Some moulds are used in cheesemaking to develop flavour and texture, and these kinds are safe to consume. For example, blue cheese gets its distinct bluish veins from mould, and Brie gets its thick outer rind and soft, creamy interior from the introduction of mould during processing. Other cheeses that are meant to be mouldy include Roquefort, Gorgonzola, Stilton, and soft-ripened cheeses like Brie and Camembert.
It is important to note that even if the mould itself is scrubbed off or cut away, the toxins produced by certain moulds might remain. Therefore, it is crucial to recognise the different types of mould and take the necessary precautions to prevent food spoilage and potential health risks.

Frequently asked questions
Cooking can kill some types of mold, as heat disrupts the viability of mold by preventing it from growing or spreading. However, not all molds are killed by heat, and the toxins produced by certain molds may remain on the cheese even after cooking. Therefore, it is generally recommended to cut off and discard moldy parts of hard cheeses and discard moldy soft cheeses entirely.
Some types of mold are intentionally introduced during the cheesemaking process to develop flavor and texture, such as Penicillium (P.) roqueforti, P. glaucum, and P. candidum. These molds are safe to consume and are commonly found in blue cheeses like Gorgonzola and soft-ripened cheeses like Brie.
To prevent mold growth on cheese, it is important to store it properly. Keep cheese cold, preferably in the refrigerator, and only take it out when in use for less than two hours. Additionally, use plastic wrap to cover the cheese and help keep it mold-free for longer.
