1. Shopping cart
Chuck Gerba, an environmental microbiologist at the University of Arizona in the United States, once took a sample from a supermarket shopping cart and found that the cart was full of bacteria. There are even 80% of shopping carts with E. coli. This is a type of fecal bacteria that is usually spread through contaminated hands. Gerba’s research team also discovered some bacteria and viruses that can cause typhoid fever, flu and diarrhea. In addition, a recent study showed that putting children in a shopping trolley also increases their risk of contracting Salmonella bacteria.
If you want to avoid bacteria during supermarket shopping, it is best to disinfect the handles of the shopping cart. If you want to put your child in the cart, it is best to wipe the seat, or remember to wash your hands after returning home from shopping. Gerba advises not to put the child in the car. If you have to do this, use a disposable product to cushion the seat instead of towels and other cloth products, which will only contaminate more bacteria.
2. ATM and touch screen
Next time you use an ATM or self-service machine, remember to wash your hands. Gerba’s research team found that most public touch screen machines or keyboards have E. coli, as well as many other common bacteria and viruses. Some touch screens even have methicillin-resistant Staphylococcus aureus (MRSA), which is highly resistant to several antibiotics. MRSA can cause some serious skin infections and sometimes death.
Gerba recommends minimizing the use of self-service machines. Gerba’s test on ATM screens found that those machines that are placed outside all the year round have fewer bacteria in the hot and dry environment than those placed in the room in a cold and humid environment. You can wipe the screen with a sterile wet tissue before using this type of touch screen machine, or wash your hands after use.
When you brush your teeth, you wipe off some of the mucous membranes in your mouth. Gerba said, “I don’t even share a toothbrush with the person who kisses me.” Blood-borne diseases, such as hepatitis B, hepatitis C, and AIDS, are all spread through toothbrushes, but these diseases are unlikely to be spread through kissing. You may even contract other people’s respiratory diseases or other diseases, such as typhoid fever or flu, from sharing toothbrushes.
When you go to a friend’s house to wash up overnight, you may want to borrow a friend’s comb. In fact, combs are also something that cannot be shared. Gerba said, “Bacteria on the skin and flaked dander will stick to the comb.” He also found MRSA and other bacteria on the comb.
So what about the comb used by the stylist in the hair salon? Make sure they disinfect the comb every day to minimize the spread of bacteria.
You may meet an interesting colleague at the meeting and want to exchange contact information. Should you accept the pen she/he lent you? Private pens are easy to breed bacteria, because many people have the habit of biting the pen tube. Gerba said, “With this pen, you will easily get respiratory viruses and oral infections.” Gerba’s research found that teenagers’ pens The germs are the most.
Surprisingly, the pens on the store counters contain far fewer germs. This may be because they are scrubbed every day, and no one puts these pens in their mouths. Gerba recommends that people bring their own pens, or wipe them with sterile tissues when using other pens.
6. Mobile phone
There are a lot of pollutants attached to mobile phones, and people rarely notice or even clean them up. Gerba’s research found that MRSA and other bacteria, including influenza viruses, can breed on mobile phones.
A woman’s cell phone is dirtier than a man’s. Because cosmetics can easily carry germs, or in fact, more women get colds than men every year. “According to statistics, women get colds about 3 times a year,” Gerba said. When you borrow a mobile phone, it is best to wipe it with a sterile tissue, or remember to wash your hands after use.
razors cannot be shared either. Shaving sometimes causes wounds and cuts. Whether you see the blood on the razor or not, when you are shaving, germs are always spread. Gerba said, “You will always scratch your skin, so be careful.” When you forget to bring a razor at a friend’s house overnight, don’t borrow someone else’s razor. Don’t even use your parents’ razor. Blood-borne diseases cannot be underestimated. A person may carry a certain disease (such as hepatitis B) for a lifetime without even knowing it.
When you go shopping and want to touch up your makeup, it’s best to use your own cosmetics instead of trying them out at the counter. A two-year study found that most cosmetic samples in pharmacies or shopping malls contained high levels of bacteria. The contaminants found ranged from Staphylococcus aureus to Escherichia coli. The cosmetic samples tested were from Friday, Saturday and Sunday. The study found that there were more bacteria in cosmetic samples on Sunday than Friday.
