Everywhere in the world, there are bacteria, most of which are harmless to humans, and some are even beneficial. However, in certain circumstances, a small number of bacteria can cause severe illnesses. To address this, experts have identified 10 common everyday items that are prone to bacteria growth and have provided ways to protect oneself.
In an article on The Conversation website, Manal Mohammed, a senior lecturer in medical microbiology at the University of Westminster in the UK, highlighted some hidden bacteria breeding grounds in daily life and simple methods for self-protection.
The kitchen sponge may be one of the dirtiest items in the house. Sponges are porous, moist, and frequently come into contact with food, providing an ideal environment for bacteria growth.
Research by the National Sanitation Foundation in the United States found that a sponge can harbor millions of bacteria, including E. coli related to fecal contamination, just two weeks after initial use.
Self-protection tips – disinfect the sponge weekly by heating in the microwave, soaking in vinegar, or washing in the dishwasher. Replace the sponge if it develops an unpleasant odor, even after cleaning.
Cutting boards with knife marks can breed bacteria. Salmonella and E. coli can survive for hours on a dry surface, posing health risks if the cutting board is not properly cleaned.
Self-protection tips – use separate cutting boards for raw meat and vegetables. Thoroughly clean cutting boards with hot soapy water after each use, rinse thoroughly, and allow them to dry completely. Replace cutting boards when deep grooves appear.
Many people use shopping carts every day, but they are rarely disinfected. This makes the cart handle a breeding ground for bacteria, particularly disease-spreading bacteria.
Research has shown that over 70% of shopping carts are contaminated with E. coli, which is often associated with fecal contamination. Studies also indicate the presence of Klebsiella pneumoniae, Citrobacter freundii, and Pseudomonas on shopping carts.
Self-protection tips – disinfect the cart handle before use, especially in situations where you may touch food, a cell phone, or your face.
Tea towels are often reused in the kitchen for drying hands, wiping surfaces, and cleaning spills, but they are not washed frequently enough. Studies have shown that E. coli and Salmonella can survive on tea towels for hours.
Self-protection tips – use paper towels when possible or separate tea towels for different purposes. Regularly wash them in hot water, bleach, or disinfectant.
Phones are carried everywhere, including bathrooms, and are frequently touched, making them prone to bacterial contamination. Research has shown that phones may harbor harmful bacteria, including Staphylococcus aureus.
Self-protection tips – avoid using phones in the bathroom and wash hands regularly. Clean phones with a slightly damp microfiber cloth and mild soap, avoiding the use of harsh chemicals.
Flushing toilets release tiny splashes that may land on nearby toothbrushes. Studies have found that toothbrushes in bathrooms can harbor E. coli, Staphylococcus aureus, and other microbes.
Self-protection tips – store toothbrushes away from toilets whenever possible. Rinse toothbrushes thoroughly and store them upright to air dry after each use. Replace toothbrushes every three months, or sooner if bristles show significant wear.
After each shower, fabric bath mats absorb water, creating a warm and moist environment that is conducive to bacterial and fungal growth.
Self-protection tips – hang bath mats to dry after each use and wash with hot water weekly. For a more hygienic option, consider using wooden or diatomaceous earth mats that dry quickly and reduce microbial growth by removing residual moisture.
Studies have shown that hotel TV remotes may be dirtier than toilet seats as they are touched by many people but are rarely disinfected. Common bacteria found include E. coli, Enterococcus, and Staphylococcus aureus.
Self-protection tips – upon checking into a hotel, wipe the remote control with antibacterial wipes. Some guests even use plastic bags to cover remotes. After using shared items like these, remember to wash hands.
Towels and toys used by pets come into contact with saliva, hair, urine, and outdoor bacteria. The Centers for Disease Control and Prevention in the United States have indicated that pet toys may harbor E. coli, Staphylococcus aureus, and Pseudomonas aeruginosa.
Protecting yourself and your pet – wash pet towels weekly with hot water and pet-safe cleaners. Allow pet toys to air dry or use a dryer. Regularly replace worn or damaged toys.
Nail clippers, cuticle pushers, and other beauty tools, if not cleaned properly, can spread harmful bacteria, including Staphylococcus aureus.
Self-protection tips – bring your own tools to the salon or inquire about their sterilization process. Reputable salons will be happy to explain their procedures.
