I believe that many people have the habit of scalding tableware with boiling water first and then eating when going out for dinner. I did this before, thinking that this can achieve the purpose of disinfection.

But after a deeper understanding, I found out that boiled water and scalding tableware may not be as effective as I thought.

Is boiling tableware really effective?

What we generally call disinfection is essentially to remove the remaining microorganisms on the surface of the tableware, and these microorganisms are specifically divided into: Staphylococcus aureus , Salmonella, E. coli and mold. Different microorganisms have different temperature tolerances. Whether they can be completely eliminated depends on the situation.

① Staphylococcus aureus

This bacteria will have an impact on the human body under certain conditions, such as vomiting, stomach cramps, and diarrhea and other food poisoning conditions. can usually be killed at a high temperature above 80℃ for 30 minutes.

②Salmonella

This bacteria is not very harmful and is generally eliminated at the temperature of 55-60℃ for 15-30 minutes.

③Escherichia coli

It exists in all aspects of our lives, water, food, and even in the human intestines. This is a normal situation and generally does not cause much harm to the human body. and it is not resistant to high temperatures and can be killed after waiting for about 1 minute at 75℃.

④Mold

Ordinary mold will be killed at a temperature of 70-80℃ , but if it is a fungus (such as when the bowls and chopsticks are moldy), it will not be eliminated by scalding it with high-temperature hot water.

⑤Virus

Tableware can also carry viruses, especially public tableware provided in some restaurants. Although most viruses are not contagious, similar to hepatitis A and hepatitis B virus need to be eliminated at a temperature of 100℃.

To sum up, it is not difficult to find that:

Although different microorganisms have different tolerance to temperatures, most microorganisms have to undergo a long period of high temperature baptism before they can be completely eliminated. When we go out for dinner, it takes only a few minutes to wash tableware with hot water. In addition, the water temperature provided by some restaurants does not meet the standards, which can have a cleaning effect. , but the effect of sterilization and disinfection is very small.

Can the dining cloth be cleaned?

It is best not to use a dining cloth to wipe tableware. This kind of cloth often has more microbial bacteria on tableware. You can wipe your hands, but don’t use it to contaminate tableware. The same is true for daily use of tableware at home. Don’t treat dishcloths as universal!

Of course, you don’t have to panic. As long as you go to a restaurant that meets the hygiene standards, the tableware provided generally meets the consumption standards. Even if you use it directly without using water to burn it, it will not cause too much harm to the human body.

If you are really worried about hygiene, you can bring your own tableware or choose disposable tableware when you go out to reduce the risk of contamination.
