What You'll Learn
Long nails can spread harmful bacteria and fungi
Long nails can act as a breeding ground for harmful bacteria and fungi, increasing the risk of infection and disease transmission. The longer the nail, the more surface area available for microorganisms to adhere to. This makes it challenging to thoroughly clean the nails and underlying skin through handwashing or scrubbing.
Several studies have found a range of bacteria and fungi underneath fingernails, including 32 different bacteria and 28 types of fungi in one investigation. These microorganisms can lead to infections, as evidenced by the presence of antibiotic-resistant bacteria like MRSA (methicillin-resistant Staphylococcus aureus) and other staph bacteria. Long nails have been linked to the spread of infections in healthcare settings, with reports of outbreaks in NICUs and contributing factors in patient deaths.
Healthcare workers are typically required to maintain short nails to mitigate the risk of transmitting diseases. However, it is essential to note that even with proper handwashing, long nails can still harbour bacteria and fungi. This is because the additional surface area and spaces under longer nails create an ideal environment for the growth of dangerous microbes, making it more challenging to achieve effective decontamination.
The risk of transmitting harmful microorganisms through long nails is not limited to healthcare settings. Everyday activities such as nail-biting, nose-picking, finger-sucking, and food preparation can also facilitate the spread of bacteria and fungi from long nails to the body or others. Therefore, maintaining short and clean nails is crucial to reducing the risk of nail infections and the spread of harmful microorganisms.
To ensure nail hygiene and reduce the risk of infection, it is recommended to keep nails trimmed and clean. Scrubbing the underside of nails with soap and water or using a nail brush during handwashing can help remove dirt and germs. Additionally, it is essential to clean nail grooming tools before use and avoid biting or chewing on nails. By following these practices, individuals can help prevent the spread of harmful bacteria and fungi associated with long nails.

Long nails are linked to infant deaths in NICUs
Long nails have been linked to infant deaths in NICUs (Neonatal Intensive Care Units). Several studies have found a correlation between long or artificial nails on nurses and the transmission of bacteria in NICUs, which can lead to infections and, in some cases, infant deaths.
In one case, a NICU baby contracted E. coli and passed away. The infection was linked to a nurse's long nails, which had bacteria underneath them. This prompted conversations and reminders about the importance of proper hand hygiene and nail care for nurses and other healthcare professionals.
Long nails, whether natural or artificial, provide more surface area and spaces for bacteria and pathogens to adhere to and grow. Health experts say that nails extending more than 1/4 inch beyond the fingertip can harbor significantly more bacteria and pathogens than short nails. These microbes, such as methicillin-resistant Staphylococcus aureus (MRSA) and other staph bacteria, can then spread to patients through touch or improperly washed hands.
Studies have found a variety of bacteria and fungi underneath fingernails, including MRSA, staphylococcus, and Pseudomonas aeruginosa. When nurses trimmed or removed their long nails, the number of new Pseudomonas cases dropped, further emphasizing the link between long nails and the transmission of pathogens.
Proper hand hygiene and short nails for medical staff are crucial in mitigating the risk of infection and ensuring the safety of vulnerable patients, especially in high-risk settings like NICUs. While most nurses today are well-informed about hand hygiene, hospitals and healthcare institutions are implementing policies requiring short nails for nurses to reduce the potential for pathogen transmission.

Long nails are unhygienic in food prep settings
Long nails can be unhygienic in food preparation settings due to the increased risk of transmitting bacteria, fungi, and other pathogens. Nails that extend beyond the fingertip provide more surface area and spaces for microorganisms to adhere and grow, making it challenging to properly clean hands and nails through handwashing or scrubbing. This heightened presence of microbes can then be transferred to food during preparation, potentially leading to food contamination and subsequent health risks for consumers.
Several studies have linked long nails to the transmission of harmful bacteria, including MRSA (methicillin-resistant Staphylococcus aureus) and other staph bacteria. These bacteria can cause serious infections, particularly in vulnerable individuals such as hospitalized patients or those with weakened immune systems. In food prep settings, the presence of these bacteria on the hands of food handlers can result in the contamination of food items, leading to potential health risks for those who consume the prepared meals.
Long nails can also harbor fungi, which can be transferred to food during preparation. While some fungi may not cause significant harm, others can contribute to infections or allergic reactions in susceptible individuals. Additionally, long nails can break more easily, and broken nails can further increase the risk of contamination as the broken area provides an additional harborage for microorganisms.
Furthermore, long nails can hinder proper handwashing and nail cleaning techniques, which are crucial in food prep settings to prevent the spread of germs and infections. Nails should be kept short and clean to minimize the risk of transmitting dirt, bacteria, and other pathogens. This is especially important in environments where food is being handled, as it helps to maintain sanitary conditions and reduce the likelihood of foodborne illnesses.
To ensure hygienic practices in food prep settings, it is recommended to trim nails frequently, scrub the underside of nails with soap and water or a nail brush, and practice proper handwashing techniques regularly. These measures help reduce the buildup of microorganisms and prevent their transfer to food. Additionally, avoiding nail-biting or finger-sucking is crucial, as it can introduce harmful bacteria and fungi into the body and contribute to the spread of infections.

Long nails can cause fingernail infections
Long nails can harbour bacteria and fungi, which can lead to fingernail infections. Nails provide an ideal surface for microorganisms to adhere to and carry out their life processes. Studies have found 32 different bacteria and 28 different fungi underneath fingernails. The longer the nail, the more surface area there is for these microorganisms to colonise.
One particular type of fingernail infection is paronychia, which is an infection of the skin around a fingernail or toenail. It usually occurs when the skin around the nail is irritated or injured, creating an entry point for bacteria and fungi. Paronychia can be bacterial or fungal, with the latter tending to be less obvious and more chronic. Symptoms of paronychia include pain, swelling and tenderness around the nail, redness, warmth, and pus accumulation. In some cases, an abscess may form, requiring drainage by a doctor. Antibiotics are often used to treat paronychia, with antifungal medications being prescribed for fungal infections.
Healthcare workers are required to keep their nails short due to the risk of transmitting disease. In one instance, two nurses with long nails may have contributed to the deaths of 16 babies due to the presence of bacteria underneath their nails.
To prevent fingernail infections, it is important to maintain good nail hygiene. This includes regularly washing hands, keeping nails clean, and avoiding biting or picking at nails and cuticles. Nails should be trimmed regularly, but not cut too short, and cuticles should not be cut or pushed back.
