The everyday objects most full of bacteria and that almost no one cleans well

In daily life, people often use a large number of objects that quickly become filled with living microorganisms that can reproduce rapidly and, while they may not cause any harm, can trigger illness.

That's why it's important to be very careful with cleanliness , because if you're careless, you may catch some diseases more frequently. Read more: Does Colombia have the best gastronomy in Latin America? This is what AI says.

These germs or bacteria aren't limited to places considered contaminated, like the bathroom, for example, or surfaces that are obviously dirty. They also live on objects that are used daily.

In this way, several investigations have revealed which objects are those that harbor within themselves the greatest amount of bacteria and microorganisms that are not entirely beneficial .

A University of Arizona study, led by microbiologist Charles Gerba, revealed that cell phones, computer keyboards, kitchen sponges, and cutting boards contain more bacteria than the average toilet bowl.

Dish sponges

Kitchen sponges, in particular, are major sources of contamination: a study published in Scientific Reports (2017) found more than 360 different types of bacteria on these sponges, including strains of Escherichia coli and Klebsiella . This is due to their constant humidity and frequent contact with organic waste. See more: In pictures: this was the commemoration of July 20 and the military parade

Market cart

Another object of concern is the shopping cart. According to a study in the Journal of Medical Virology (2012), these carts can contain traces of saliva, blood, fecal matter, and nasal secretions, making them potential vehicles for bacterial and viral transmission.

Remote control

Additionally, items such as hotel television remote controls, light switches, and door handles have also been identified by research as critical sites for bacterial buildup (Gerba et al., 2005). This research highlights the importance of frequent hand hygiene and regular disinfection of these commonly used objects .

Chopping board

Cutting boards, especially if they're made of wood or have deep cuts, can harbor a large number of bacteria due to the accumulation of organic debris and moisture. Studies have shown that this kitchen utensil can harbor bacteria such as Salmonella, Escherichia coli, and Listeria monocytogenes , especially if used to cut raw meat and not properly sanitized afterward.

Research like that of microbiologist Charles Gerba indicates that, in many cases, cutting boards can harbor more bacteria than a toilet seat . Therefore, it is recommended to use separate boards for meats and vegetables, and clean them with hot water and disinfectant after each use to avoid cross-contamination.

Kitchen towels

Hand towels, especially if used by multiple people and not thoroughly dried between uses, can become an ideal breeding ground for bacteria and other germs. Research has found that these moist textiles can harbor bacteria such as E. coli, Staphylococcus aureus, and molds, which multiply rapidly in warm, humid environments like bathrooms.

A study published in Scientific Reports (2017) showed that reused towels can accumulate thousands of bacteria per square centimeter , increasing the risk of skin or gastrointestinal infections if they come into contact with wounds or mucous membranes. Therefore, experts recommend washing towels frequently, drying them thoroughly, and not sharing them with others. VALENTINA DELGADILLO ABELLO
