The mobile phone is dirty than the toilet. These places are full of bacteria

According to statistics, each ordinary person carries an average of 150 kinds of bacteria, so human hands are considered to be dirtier than sitting toilets in the toilet. Some of these bacteria carried by humans may cause serious diseases. Data shows that people may touch 300 different object surfaces every half an hour, and then touch their face 18 times an hour on average. These actions can easily lead to bacteria entering the mouth or nose, attacking human cells and causing discomfort. British media pointed out that 65% of colds, 50% of diarrhea and 50% – 80% of food poisoning were caused by bacteria on TV remote control or light switch.

If you keep your mobile phone in your hand, it is very likely that your mobile phone is full of bacteria. In order to study the dirtiness of a person’s mobile phone, students studying bacteria at the University of Surrey put their mobile phones in a bacterial Petri dish. Three days later, they studied the bacteria that had grown out, and they were shocked. The above picture is the photo of the cell phone bacterial culture experiment. The bacteria have grown to disgusting levels. Professor Park said: “it seems that mobile phones can not only store mobile phone numbers, but also clearly record what we have come into contact with. The niche of Staphylococcus in the human body is the nostrils, so digging through the nostrils and texting will make your mobile phone stained with this pathogen.”

In many cases, bacteria are relatively harmless. Generally speaking, touching unclean surfaces or improper hand washing will leave bacteria on your hands. But sometimes, bacteria may induce infection, leading to food poisoning, pustulosis and even sepsis.

Bacteria on mobile phones are comparable to toilets. In addition to these, what other places in daily life are “playgrounds” for bacteria?

bank ATM: the playground of Pseudomonas aeruginosa

It is common knowledge that money is dirty, because it has been passed by countless hands and may be contaminated with various dirt bacteria. But many people ignore the filth on the ATM. Scientists say that if they know the truth, they may want to wear gloves next time they withdraw money. According to the test of health experts, the ATM is dirtier than the public toilet, because there are special personnel to clean the public toilet every day, and the cleaning of the ATM is often ignored.

It is understood that in terms of ATM cleaning, off-line banks often entrust cleaning companies to be responsible, while in-line banks, the cleaning personnel at the outlets do it all by themselves. According to a cleaning staff, although the ATM is cleaned every day, it is basically clean water or detergent, not disinfectant, and the places in the gap that cannot be cleaned are generally ignored.

On the ATM, especially its button, experts found rod-shaped bacteria samples such as Pseudomonas aeruginosa, which are less pathogenic but strong in drug resistance. Although they are not generally harmful, they can still cause diseases, especially diarrhea and even eye diseases. As for how to deal with the bacteria on the ATM, experts say that it is very simple. You only need to use antibacterial hand sanitizer to wash after using the ATM to avoid problems.

bank card: a playground for rhinovirus and coronavirus

A study found that 80% of bank passbooks or cheques, as well as 78% of bank cards and credit cards, are hotbeds of bacteria, including pathogenic bacteria such as rhinoviruses. Rhinovirus infection mainly causes upper respiratory tract infections such as common cold in adults; In infants and children and patients with chronic respiratory diseases, in addition to upper respiratory tract infection, bronchitis and bronchopneumonia can also be caused. The two major causes of common cold are rhinovirus and coronavirus.

Professor Lang kutler of Queen Mary University in London pointed out: “we all often take cash and credit cards, but it is unlikely that we all wash our hands afterwards.” It is not practical to wash your hands every time you use money. However, you should avoid touching your face after using your bank card. It is better not to touch it, because bacteria may enter your nose or mouth.

water bottle: coliform playground

Many reusable plastic water bottles may become “bombs” for germs. Experts from the University of Calgary in Canada found that 9% of the water bottles used by students in the university can detect a high amount of coliform.

Experts pointed out that if water bottles are to be recycled, they need to be cleaned with hot soapy water. Pay special attention to the narrow bottleneck of the water bottle. Because of the bottleneck, even if you have a dishwasher, you can’t use it to clean the water bottle.

door handle: a playground for Salmonella bacteria

Microwave oven is a world-famous dirty and unwashed item. “Kimberly Clark health project” has collected thousands of samples, and the test results show that the handle position and button surface of the microwave oven are among the dirtiest of all items, containing Salmonella and other bacteria. Experts suggest that the microwave oven should be wiped and disinfected regularly, especially after cooking raw meat.

In fact, the positions of various door handles are a paradise for bacteria. A study in the United States found that in addition to microwave ovens, refrigerators and even doorknobs for furniture or offices, it is easy to leave the virus of cold patients, and they may survive for two days. If it is a hotel, 40% of door handles contain cold germs, such as coronavirus. According to scientists’ research, copper handles are easier to kill germs. If they are made of other materials, they should be disinfected every two days.

button switch: playground for Staphylococcus aureus and Streptococcus aureus

When you press a button, you may open the door of bacteria to your body. A study in the United States found that the levels of Staphylococcus aureus and Streptococcus on the hotel’s light switch were similar to those in the toilet and bathroom, so they needed to be cleaned twice a week, and if someone was sick, they needed to be disinfected every day.

The bacterial content of buttons in ordinary elevators is almost 40 times that of public toilets, including MRSA Staphylococcus aureus. Experts in Arizona found 313 colonies per square centimeter on elevator buttons, and it is difficult to clean. After pressing the elevator, you need to clean them with antibacterial hand sanitizer.

Tests conducted by the University of Virginia in the United States found that nearly half of TV remote controls carry rhinovirus, which can survive for several days, and some viruses can survive for several months. Moreover, the bactericide has little effect on the remote controller, because it is difficult to clean the gap. Therefore, it is better to use a plastic sheath for the remote controller, so that it can be cleaned and disinfected every day.

toiletries: amusement park for Escherichia coli and Candida

what? Do you have bacteria when you use toiletries every day? you ‘re right!

A toothbrush is a tool used to clean the mouth. However, the toothbrush itself may be full of bacteria. Because the air in the bathroom is filled with millions of bacteria, including Salmonella and E. coli, many of which may fall on the toothbrush. Experts from the University of Manchester pointed out that every toothbrush contains 10 million bacteria on average, including Escherichia coli and Candida.

These two kinds of germs may cause diarrhea, peritonitis, cholecystitis, stomatitis, pyelonephritis, meningitis, bacteremia and biliary tract infection. Drying, sunlight, ultraviolet rays and chemical agents are difficult to kill the bacteria on the toothbrush. How to prevent them from being attacked by the germs on the toothbrush? British experts suggest that a toothbrush should be replaced at least 90 days, and the toothbrush should be placed in a closed container.

washing machine: E. coli playground

Washing machines are tools for cleaning clothes, but they contain a large number of bacteria. On average, each washing machine contains 100 million E. coli viruses. Experts stress that even low-temperature cleaning is not enough to kill these bacteria. The position of the washing machine is very important. It should be in a ventilated and dry place, and should not be placed in the toilet. After washing clothes, keep all parts of the washing machine dry, especially the drainage pipe, filter bag and other parts.

A study in Germany found that Staphylococcus aureus is often carried on clothes, which is easy to remain in washing machines, and it may cause pneumonia in the human body. How to deal with the virus in the washing machine is not impossible. Experts say that you can use water above 40 ℃ for cleaning, or add detergent or detergent at the same time as adding bleach. After the washing machine has been used for half a year, it should be cleaned and disinfected every two or three months.
