These five bacterial nests around me
Everyone thinks that the underwear they wear is dirty. It's safe to wash it. However, the washing machine contains about 100 million E. coli. Even if the clothes are cleaned, the bacteria will remain on them. However, the solution to this problem is very simple. If the water temperature in the washing machine is raised to 60-66 ℃, the bacteria will be killed.
Lemon slices in drinks
Although lemon has antibacterial effects, the lemon slices in the water glass are covered with bacteria. The results showed that 70% of lemon slices in restaurants carried pathogenic microorganisms. According to the survey of New York University, 50% of lemon tablets are positive in human fecal test. This may be due to improper handling of fruit by restaurant staff or contamination from raw meat in the kitchen. Therefore, in order to avoid being infected by germs, it is suggested that when dining in the restaurant, do not ask for additional fresh lemon slices when ordering drinks.
new clothes
After testing the clothes just purchased from the store, it was found that the new clothes contained some skin bacteria, feces and respiratory secretions. It is suggested that after buying new clothes, you must soak them in hot water before wearing them.
Dashboard of car
After testing bacteria in 100 cars, it was found that the dashboard is one of the largest bacteria accumulation areas in the car, and the number of bacteria can be "comparable" to the door handles in public places. This is because the car air conditioner and heater will blow the bacteria into the car at any time, they stay on the dashboard rarely touched by the driver, and they multiply there, which is easy to cause inhalation respiratory diseases to the driver. Remind everyone, wipe the dashboard with disinfectant at least once a week.
contact lens case
Researchers in China have found that 34% of contact lens cases are contaminated by Serratia and Staphylococcus aureus, which can cause keratitis and even blindness.
It is recommended that you do not keep the used cleaning solution in the contact lens box, and pour it out immediately after use. Scald the lens box with boiling water once a day, and replace it with a new one every three months. In addition, as the cleaning solution of contact lenses will lose the ability to kill bacteria after eight weeks, it is recommended that you replace a new bottle of cleaning solution every two months.
