You might be surprised to learn that washing machines can harbor bacteria and other microorganisms that can make you and your family sick.
Washing machines can be a breeding ground for bacteria like E. coli and Salmonella, which can be transferred to clothes and then to your skin.
According to the article, washing machines can be contaminated with a variety of bacteria, including Staphylococcus aureus, which can cause skin infections.
It's not just bacteria that's the problem - mold and mildew can also grow in washing machines, especially in areas with poor ventilation.
Regular cleaning and maintenance of your washing machine can help prevent the growth of these microorganisms.

Diseases from Washing Machines
Washing machines can spread diseases, and it's not just a matter of using the right detergent or washing cycle. A standard household washing machine doesn't automatically sanitize clothes, and many problematic germs can survive the washing machine.
The average washing machine water is around 70 degrees Fahrenheit, which is too cold to kill many pathogens. Unless temperatures reach 100 degrees Fahrenheit, germs like salmonella and COVID can still be present on your clothes after a normal wash cycle.

Germs can stick around even after a thorough wash due to two main mechanisms: the use of cold water and the wrong wash cycle or detergent. If you use a gentler laundry method, some debris like dust, skin cells, and mucus particles can remain on your clothes, providing a feeding ground for microbes.
Contaminated laundry can spread diseases more often than you think. Germs that were originally on one person's clothes can end up on someone else's clothes, leading to surprisingly high rates of infection.
Here are some ways contaminated laundry can harm your health:
- If you wash a batch of clothes that a sick person wore, germs may end up on a healthy person's garments.
- The person doing the laundry is at a high risk of getting infected, especially if they don't wash their hands after handling contaminated clothes.
- Germs can linger in the washing machine and end up on someone else's clothing, making it harder to stay safe, especially in situations where you don't know who used a machine last.
To reduce the risks of illness associated with contaminated laundry, it's essential to properly maintain your washing machine and keep it as clean as possible. Experts recommend keeping your washing machine door cracked open between loads to increase airflow and inhibit mold growth.
You can also deep clean your washing machine to remove mold and other potential pathogens. A monthly cleaning can remove mold and other debris. If your washing machine was recently used for contaminated laundry, you might also want to deep-clean it after using it.
Some older washing machines may have a faulty gasket that almost always has mold. If you find that a monthly cleaning isn't enough to keep mold at bay, it may indicate that you need a replacement seal.

Causes of Contamination
Washing machines can be breeding grounds for bacteria, and it's not just about the clothes you wash. The appliance itself can harbor germs and spread them to your next load of laundry, making it a potential source of contamination.
Germs can linger in the washing machine and end up on someone else's clothing, especially in situations where you don't know who used a machine last. This makes it even harder to stay safe.
A University of Arizona study found that test subjects would put clothes in the dryer without washing their hands, and then end up with germs on their hands which they could accidentally ingest.
The warm water and damp interior of a washing machine creates the perfect breeding ground for microorganisms. This is especially true when using energy-saving cold and lukewarm water, which can't kill off certain bacteria like Klebsiella oxytoca.
Soap scum and detergent residue buildup can provide nutrients needed for bacteria and mould growth. This can be caused by using unclean machines or leaving the detergent dispenser dirty.
Here are some common causes of contamination in washing machines:
- Unclean machines
- Buildup of soap scum and detergent residue
- Warm, moist conditions
- Detergent buildup around the detergent dispenser, gasket, or drum
A dirty washing machine may not be able to effectively clean your clothes, and you may notice that your clothes may start coming out with stains or odours. If your laundry frequently develops mould or mildew, it could be due to a contaminated washing machine.

Detecting and Preventing
Mold in washing machines can be surprisingly hard to spot, but the first sign is often a sharp, sour, musty, or earthy smell.
The smell will be present when you open the washing machine, and even worse, it will be on your clothes, no matter how well you wash and dry them.
Mold is typically black, green, brown, or gray, and it often looks powdery or slimy. You should check the creases of the rubber seal on your washing machine door, as well as the drum and outer shell.
In severe outbreaks, the mold may also grow between the drum and the outer shell, making it tricky to spot. However, you should also check your clothing for little black spots or discolorations.
Research indicates that front-load washing machines are over five times as likely to develop mold as top-loading washing machines, due to the special rubber seal that traps moisture.

If you have an older front-loader, you're more likely to experience mold, but even newer models can still develop mold due to poor maintenance.
To prevent mold growth, keep your washing machine door cracked open between loads, which increases airflow and inhibits mold growth.
You can also deep clean your washing machine monthly to remove mold and other potential pathogens. If your washing machine was recently used for contaminated laundry, you might want to deep-clean it after using it.
Here are some signs of a dirty washing machine:
- Musty or mildew odors
- Stains or discoloration on the interior
- Detergent buildup around the detergent dispenser, gasket, or drum
- Unusual noises, such as grinding or rattling
- Reduced washing machine performance
- Mold or mildew growth on laundry
Risk Factors
You're at risk of catching illnesses from laundry if you're not careful, especially if you're sharing a washing machine with people whose lifestyles you're not aware of.
Normal washing habits are usually fine if your household is healthy and hasn't been exposed to anyone sick, but it's hard to guarantee that clothes haven't been around someone who's ill.
You should exercise particular care with your laundry if you live with someone who's sick, as clothes can be contagious weeks later.

Health Risks
Washing machines can spread diseases, but it's not a guarantee. In fact, the risk depends on various factors like washing machine cycles and types of disease.
The risk is higher if you're sharing a washing machine with people whose lifestyles you're not aware of. This is especially true if you're washing clothes that a sick person wore, as germs can end up on a healthy person's garments.
Gastrointestinal diseases are most likely to spread through clothes, and clothes can be contagious weeks later. If you were in a public space where disease spread was likely, you should wash your clothes more thoroughly.
People who work in healthcare facilities or as first responders always need to be cautious with work clothes. Those who are immunocompromised also need to be careful.
Here are some high-risk situations where you need to exercise particular care with your laundry:
- When one member of the household is sick
- When you're washing clothes that a sick person wore
- When you're sharing a washing machine with people whose lifestyles you're not aware of
