Cheese mites are microscopic arachnids that feed on moulds found on the surface of aged cheeses. They are typically found on hard cheeses with natural rinds, such as cheddar, mimolette, comté, and cantal. While they may seem unappetizing, cheese mites are generally harmless to humans and can even enhance the flavour of the cheese. However, in excessive amounts, they can render cheese inedible, and some people may experience allergic reactions or dermatitis due to mite exposure.

Cheese mites are found on many types of cheese, especially those with natural rinds
Cheese mites are arachnids, and their brains and other organs are contained within a single major body compartment called an idiosoma. They are so tiny that they cannot be seen with the naked eye, but they can be observed with a magnifying glass or a microscope. While they may be unappetising to some, cheese mites are generally harmless to humans. However, in rare cases, they can cause allergic reactions, such as dermatitis, in individuals with mite allergies.
Cheese mites play a significant role in the cheese-making process, particularly for artisanal cheeses. They contribute to the distinctive rind and flavour of certain cheeses, such as the French Mimolette, where they are encouraged to munch on the rind before being removed. The mites add an earthy smell and increase aeration, enhancing the surface area for other microbes to work. While some people may be put off by the idea of bugs on their cheese, these microbes are a natural part of the cheese-making process and can even improve the flavour.
Cheese mites are typically found on aged cheeses with natural or cloth-bound rinds. Examples include British cheeses like clothbound Cheddar and natural rinded blues such as Stilton, as well as French cheeses like Comté, Tomme de Savoie, Cantal, and Mimolette. In Germany, there is a famous mite-ripened cheese called Milbenkäse. While some people may find the presence of cheese mites unappealing, they are a common occurrence in naturally aged cheeses with hard rinds.
To minimise the presence of cheese mites, some cheeses are treated to deter them. For example, the rind of Parmesan is oiled, and Cheddar is traditionally wrapped in cloth. While these measures may not completely eliminate cheese mites, they can help reduce their population. Overall, while cheese mites may not be the most aesthetically pleasing creatures, they play a crucial role in the cheese-making process and are generally harmless to consumers.

They are microorganisms that exist everywhere
Cheese mites are microorganisms that exist everywhere. They are tiny bugs that live on the surfaces of aged cheeses, munching on the microscopic moulds that grow there. They are arachnids, and while they may not be the most adorable creatures, they are generally peaceful and harmless. They can, however, cause allergic reactions in some people, particularly those with severe mite allergies.
Cheese mites are typically found on hard cheeses with natural or cloth-bound rinds. They are especially attracted to the damp, cool atmosphere of cheese-aging chambers. While they can be found on various cheeses, they are particularly associated with the French cheese Mimolette. This cheese has a distinctive rind and flavour due to the presence of cheese mites. Mimolette is produced in Lille, near the Dutch-Belgian border, and is a hard, orange cheese similar to Edam with a thick crust full of holes. The mites munch on the rind for a few years and are then removed before the cheese is sold. However, it is challenging to remove all of them, and they can leave behind a floral, sweet flavour.
Cheese mites are also commonly found on other cheeses, such as British cloth-bound cheddars or natural rind blues like Stilton, French Comté, Tomme de Savoie, Cantal, and German Milbenkäse. These mites are usually soil-dwelling and feed on fungi in forest soils. When they encounter a cheese-making or maturation facility, they thrive due to the abundance of mould. They are also known as storage mites as they are commonly found in grains and other stored foods where mould can grow.
While some people may find cheese mites unappetizing, they are a natural part of the cheese-making process, particularly for artisanal cheeses. They can even be beneficial, as they increase aeration and the surface area for other microbes to work on, contributing to the flavour of the cheese. However, if left unchecked, they can take over a piece of cheese until it becomes inedible. Therefore, it is essential to monitor their presence and remove them when necessary.

Cheese mites are harmless to humans, but some people may have an allergy to them
Cheese mites are generally harmless to humans. They are microorganisms that exist everywhere, but they particularly thrive in the cool, damp conditions of a cheese-aging chamber. They are often found on the outside of hard cheeses, such as Cheddar, Mimolette, and Cantal, where they feed on microscopic moulds. While they can be brushed off or removed with compressed air, it is challenging to eliminate them entirely.
Cheese mites are microscopic, and one may need to zoom in to a 5X magnification to visualize them clearly. They are arachnids, but unlike their ancestors, they lack distinct body segments, with their brains and organs contained in a single compartment called an idiosoma. Their idiosoma and legs are covered in setae, whisker-like structures that aid in sensing their environment.
Despite their unappetizing nature, cheese mites are not known to cause direct harm to humans. They are commonly found in various food products and dry goods, such as grains and flours, without posing any significant risk. In fact, they are considered valuable components of natural ecosystems. However, for a small subset of individuals with mite allergies, cheese mites can trigger allergic reactions such as dermatitis.
While cheese mites themselves are not harmful, their presence on cheese products may be undesirable for some consumers. The FDA, for example, has blocked imports of French Mimolette cheese due to concerns over the presence of mites, deeming it unfit for consumption. However, it is worth noting that cheese mites are often present in aged cheeses with natural rinds, and their presence is considered a sign of a healthy environment.
In conclusion, cheese mites are generally harmless to humans, and their presence is common in many food products. However, for individuals with mite allergies, they can pose a risk of allergic reactions. The perception of cheese mites as unappealing or unsafe primarily stems from cultural and aesthetic preferences rather than any significant health concerns.

They can be brushed off the cheese without affecting its flavour
Cheese mites are microorganisms that are found everywhere. They are usually present on the outside of hard cheeses, such as Cheddar and Mimolette, with natural or clothbound rinds. They are so tiny that they cannot be seen with the naked eye.
Cheese mites are not harmful and can be brushed off the rind of the cheese without affecting its flavour. In fact, they are encouraged in normal amounts as they help moderate the microbiome on the cheese. They can, however, cause allergic reactions in a small subset of people, similar to dust mites. If you have a mite allergy, it is best to avoid consuming cheeses with mites.
Mimolette, a bright orange French cheese, is a classic example of a cheese that encourages mites. The mites munch on the rind for a few years, contributing to its distinctive flavour and rind, and are then removed—usually with a blast of compressed air and hand-brushing—before the cheese is sold. Other examples of cheeses that may have mites include British clothbound cheddars, natural rinded blues such as Stilton, French Comté, Tomme de Savoie, Cantal, and German mite-ripened cheese called Milbenkäse.
To identify if a cheese has mites, look out for brownish/grey powdery dust on the rind and a sprinkling of the same dust around the base of the cheese. This dust is a combination of living mites, dead mites, mite excretion, and cheese debris. While it may sound unappetising, it is harmless unless you have a mite allergy.

They can be removed with compressed air or a vacuum cleaner
Cheese mites are microorganisms that are found everywhere. They are especially prevalent in the damp, cool atmosphere of a cheese-aging chamber. They are also commonly found in grains and other stored foods where mould can grow. While they are generally harmless, some people may experience allergic reactions or dermatitis due to mite exposure.
Cheese mites are often found on the surfaces of aged cheeses with natural rinds, such as cheddar, mimolette, comté, and cantal. They can be identified by a brownish/grey powdery dust on the rind of the cheese, which is caused by mite activity. While they are typically brushed off the rind of the cheese, they can also be removed with compressed air or a vacuum cleaner.
For example, Mimolette, a French cheese, is known for its distinctive rind and flavour, which are a result of the presence of cheese mites. The mites are encouraged to munch on the rind for a few years, after which they are removed with a blast of compressed air and hand-brushing before the cheese is sold. However, it is challenging to remove all the mites, and they can be difficult to detect with the naked eye.
Using compressed air to remove cheese mites involves directing a stream of pressurised air onto the cheese surface to dislodge and blow away the mites. This method is effective in dislodging and removing mites from the cheese's surface and crevices. On the other hand, a vacuum cleaner can be used to suction and capture the mites, along with any dust or debris on the cheese's surface. This method ensures that the mites are removed and contained within the vacuum cleaner, reducing the risk of them spreading to other areas.
While cheese mites may be unappealing to some, they play an essential role in the cheese-making process, contributing to flavour development and increasing aeration. They are also a sign of a healthy cheese-aging environment, as long as their population is controlled.
