Is it reliable to use hot water to scald tableware?

Friends, is there anyone around?

Do you like to scald the dishes and chopsticks with tea when you go to a restaurant?

Tell him, it's probably useless.

Can remove dust

But if the purpose is high temperature sterilization

Whether it is water temperature or soaking time

The disinfection effect cannot be achieved!

Below we list some

Bacteria that are easily retained on dishes and chopsticks

Talk about the precautions for high temperature sterilization in life

Staphylococcus aureus

It is a very common bacteria known for its resistance to multiple antibiotics.

Generally speaking, this bacteria can survive for a period of time at higher temperatures, but after about 1-2 minutes in boiling water, the survival rate drops significantly.

S. aureus can cause conditions ranging from minor skin infections to more serious illnesses such as sepsis, endocarditis and even pneumonia.

Hot water treatment not only destroys the cell walls of bacteria, but also interferes with their metabolic pathways, thereby effectively killing the bacteria or inhibiting their growth.

salmonella

It is a common bacteria that causes food poisoning, especially in undercooked meat, eggs or contaminated foods.

Hot water can effectively kill salmonella, especially when it is boiling. For tableware, washing with boiling water can significantly reduce the number of salmonella and improve the hygiene and safety of tableware.

Listeria

It is a relatively stubborn bacterium that also exists in meat, eggs, milk and seafood, but it can survive in the refrigerator or even the freezer.

Hot water washing is relatively effective for Listeria, but it requires the water temperature to reach boiling and be maintained for a period of time. This high temperature treatment can effectively reduce the survival rate of Listeria on tableware.

Escherichia coli

A type of bacteria that lives in the intestines of humans and animals, some types of E. coli can cause severe food poisoning.

Hot water washing is an effective way to combat E. coli. Boiling water can quickly kill most E. coli, thus ensuring the cleanliness and safety of tableware.

Bacterial spores

It is an extremely heat-resistant form of bacteria. These spores can survive in extreme environments, so they cannot be eliminated by just washing with hot water.

To effectively kill bacterial spores, higher temperatures are usually required, such as pressure steam sterilization (above 100°C). In a domestic environment, hot water washing may not completely eliminate spores, but it can reduce their number.

Mold

It is a common fungus that grows in a variety of environments, especially moist areas. It can usually be killed or significantly reduced by scalding in boiling water for a few minutes.

Therefore, washing dishes with hot water can effectively reduce the presence of mold and improve hygiene safety. However, like all microorganisms, the killing of mold also depends on the time and temperature of scalding.

It is crucial to choose a reputable restaurant that meets hygiene standards.

When dining at a restaurant, you should first observe the cleanliness of the tableware. If the tableware looks dirty, you should ask for it to be replaced.

In addition, you can bring your own disinfectant wipes to wipe the tableware. Although it cannot completely replace high-temperature disinfection, it can reduce the bacteria on the surface of the tableware to a certain extent. You can also use portable ultraviolet disinfection equipment to quickly disinfect the tableware and provide more comprehensive protection.

There is no method that can completely guarantee the absolute sterility of tableware. Combining multiple cleaning and disinfection measures in life is the best option.
