Toenail fungus is a common issue that can cause embarrassment and discomfort. The fungus often causes a lingering cheesy smell, which can be distressing and impact a person's enjoyment of life. This odour is usually caused by the organism tinea unguium, but can also be the result of a type of bacteria called Brevibacterium, which is used to mature certain types of cheese. If you are experiencing this issue, it is important to consult a podiatrist for a proper diagnosis and treatment.

Toenail fungus is a common cause of cheesy-smelling toenails
The cheesy odour associated with toenail fungus is not directly caused by the fungus itself but by a type of bacteria called Brevibacterium, which also plays a role in the maturation of certain cheeses, giving them their distinctive smell. This bacteria flourish in the same conditions as the fungus, contributing to the overall unpleasant aroma.
Toenail fungus typically affects the nail from the underside, and its presence can be indicated by a range of visual symptoms. The nail may exhibit discolouration, with colours such as white, yellow, brown, or black, and may appear crumbly or chalky in texture. There can also be a soft, sticky substance with a creamy-yellow or greenish-black discolouration underneath the nail, which is often the source of the odour.
The fungus can enter the nail through small openings created by blunt force, such as a break in the seal between the nail and its bed, or through cracks, cuts, or bruises on the toenail or surrounding skin. Public places like swimming pools, showers, and locker rooms can be breeding grounds for fungal infections, especially if one walks barefoot in these areas.
To treat and prevent toenail fungus and its associated odour, it is essential to address the underlying cause. Maintaining proper foot hygiene, keeping feet dry, and wearing well-fitting shoes that allow the feet to breathe can help create an unfavourable environment for the fungus. In addition, regular sock changes, the use of foot antiperspirants or antifungal sprays, and the application of topical antifungal solutions can aid in managing the condition. For accurate diagnosis and targeted treatment options, it is recommended to consult a podiatrist or medical professional.

The bacteria Brevibacterium, used to mature certain cheeses, is responsible for the cheesy odour
Smelly toenails are often associated with sweaty feet and poor hygiene. Usually, the smell goes away with a thorough wash. However, if you notice that your toenails smell like cheese, it could be due to a bacterial or fungal infection.
The bacteria Brevibacterium, which is used to mature certain cheeses, is responsible for the cheesy odour. This bacteria thrives in dark, moist places, such as sweaty shoes, and can cause a cheese-like smell. While it is commonly associated with toenail fungus, the fungus itself does not cause the cheese-like smell. Instead, the fungus and the Brevibacterium bacteria thrive in similar conditions, which is why they often occur together.
The presence of Brevibacterium on your feet can result in a strong, unpleasant odour that may be distressing and embarrassing. It is important to address the root cause of the smell to prevent it from becoming noticeable to others. In most cases, the bacteria cause a white to yellowish discolouration on the surface of the nail, with a creamy-yellow or greenish-black discolouration of soft, sticky substance underneath the nail, which is usually the source of the odour.
To confirm whether the smell is due to a bacterial or fungal infection, it is recommended to consult a podiatrist or seek clinical diagnosis. Laboratory tests, such as mycology tests, can accurately identify the causative organism and guide appropriate treatment. Treatment modalities for bacterial or fungal infections typically involve systemic or topical preparations. Systemic treatments come in the form of medications, while topical treatments are applied directly to the nail, such as paints, lacquers, or solutions.
To prevent and manage smelly toenails, it is crucial to maintain proper foot hygiene. Ensure you wash and dry your feet regularly, especially after wearing shoes or being in sweaty environments. Change your socks frequently, use foot antiperspirants or antifungal sprays, and wear properly fitting shoes that allow your feet to breathe. These simple measures can help inhibit the growth of bacteria and fungi, reducing the likelihood of unpleasant odours.

Poor hygiene and sweaty feet can cause toenails to smell
The smell of cheese associated with toenail fungus is caused by a type of bacteria called Brevibacterium, which is also used to mature certain types of cheese. This bacteria thrives in the same conditions as the fungus, which is why the two often occur together. In addition to the cheese-like smell, other symptoms of toenail fungus include discolouration and brittleness of the toenail.
While the smell of sweaty feet can usually be washed away, a persistent foul odour may indicate an infection. White, smelly gunk under the toenails is likely to be toenail fungus. The fungus can cause a build-up of dirt or residue, which can be distressing and embarrassing for many people.
If you suspect you have toenail fungus, it's important to see a podiatrist or doctor for a proper diagnosis. They can determine if the smell is due to a fungal infection or another issue. Treatment for toenail fungus may include antifungal solutions, laser therapy, or systemic or topical medications.
To prevent and treat smelly toenails, it's important to maintain good foot hygiene. Be sure to wash and dry your feet regularly, especially if you have sweaty feet. You can also use foot antiperspirant or antifungal shoe spray to help keep your feet and shoes dry and reduce the risk of fungal growth.

A fungal infection can enter the toenail via a crack, cut, or bruise
It is indeed possible for toenails to smell like cheese, and this is usually due to a fungal infection. Fungal nail infection or onychomycosis (Tinea unguium) accounts for approximately 50% of nail conditions and is more common in toenails than fingernails. The fungus infects the nail from the underside of the nail and can be caused by any of the organisms – dermatophytes and non-dermatophytes. The infected nail may vary in colour, from brown to black, and can be associated with lifting of the nail from the nail bed. It can also cause discolouration, with a crumbly, chalky texture and a creamy-yellow or greenish-black appearance.
Wearing non-breathable shoes that keep feet warm and moist also provides the perfect breeding ground for a fungal infection to take root and spread. Tight, warm socks and boots that provide little room for toes to move comfortably are also likely to cause fungal infections. As people age, they become more susceptible to toenail fungus.
The fungus that causes the cheesy smell is called Brevibacterium, which is also used to mature certain types of cheese. This bacteria lives on the feet and causes the cheese-like smell. Both fungus and Brevibacterium thrive in the same conditions, namely dark, moist places like sweaty shoes.

Yellow toenails are usually caused by a fungal infection
Fungal toenail infections are common, with around 14% of the population affected in the United States. They are more prevalent in older individuals, with up to 50% of people over 70 experiencing them. Certain factors can increase the risk of fungal toenail infections, such as blunt force trauma to the nail, which can break the seal between the nail and the nail bed, providing an entry point for the fungus. Additionally, warm and wet environments, such as public swimming pools, showers, or locker rooms, can expose individuals to fungal infections, especially if they walk barefoot in these areas.
Wearing tight, non-breathable shoes and sweaty socks that constrict the toes can also contribute to the development of fungal infections. This is because the fungus thrives in dark, moist environments, and sweaty shoes provide the perfect breeding ground for their growth. Similarly, not wearing socks with closed shoes can increase the risk of infection, as the feet are unable to breathe, leading to excessive sweating.
Fungal toenail infections can be distressing and embarrassing for many individuals due to the unpleasant odor and aesthetic changes to the nail. The smell is often likened to cheese, although it is not the fungus itself that causes this odor. Instead, a type of bacteria called Brevibacterium, which is also used in the maturation of certain cheeses, is responsible for the characteristic funky smell. This bacteria thrives in the same conditions as the fungus, explaining why the two often occur together.
To prevent and treat fungal toenail infections, maintaining good foot hygiene is essential. This includes washing and thoroughly drying the feet, wearing proper-fitting shoes that allow the feet to breathe, and changing socks regularly. Antifungal solutions can be applied to the feet and toenails after washing, and foot antiperspirants or antifungal shoe sprays can also be used. In more severe cases, oral antifungal medication, topical medication, or laser treatments may be necessary.
