Washing dishes this way increases bacteria by 70 times! All of them are eaten by the stomach...

In daily life

Many people have this habit at home.

The washed bowls and plates are piled up together.

Take it out of the cabinet and use it the next day

But recently a friend said

This habit is not good

May cause secondary contamination of dishes

Is this true?

A trial

Previously, the Home Appliances Research Institute conducted a set of experiments, which set up two groups for comparison. The testers first disinfected the tableware and applied sterile broth on the surface of the tableware, and then divided the tableware into two groups. One group of dishes was directly stacked up and stored in the cupboard after washing, and the other group was placed upright on the shelf after washing and placed in a ventilated place.

A comparison three days later showed that the total number of colonies on the upright tableware was 8,000 cfu/set, which was in line with my country's relevant hygiene standards, while the number of bacteria on the stacked tableware was 560,000 cfu/set, 70 times that of the upright tableware.

The bacterial colony levels vary so much

There are so many bacteria on it

What health risks will it bring to our body?

In fact, the kitchen is our sanitary blind spot. If the dishes are not placed properly or are not taken care of, some bacteria and viruses may breed, which has a great impact on our body.

Acute effects in the short term: For example, some pathogenic bacteria, the most common pathogenic Escherichia coli and Salmonella, such as norovirus and rotavirus, can cause acute gastroenteritis, vomiting and diarrhea, and even dehydration and shock, which are life-threatening.

Long-term effects: Long-term ingestion of mold may contain carcinogens such as aflatoxin. Long-term exposure may cause cancer. Some studies have even shown that aflatoxin is related to liver cancer, stomach cancer, and esophageal cancer.

In addition, bowls and chopsticks are also a medium for the transmission of Helicobacter pylori. Helicobacter pylori infection is related to many stomach diseases, gastric ulcers and even gastric cancer.

Therefore, health issues in the kitchen must be taken seriously, and tableware must be disinfected properly, including when storing it, to prevent the growth of bacteria or viruses.

How to properly store dishes and bowls requires several necessary conditions for bacterial growth↓↓↓

First: nutrients are needed

Second: Suitable temperature

Third: There must be moisture

No matter how we wash our bowls and chopsticks or dishes, they can never be washed clean. Even a little bit of food residue can serve as nutrients for bacteria. If they are piled up, a lot of water accumulates, and the room temperature is suitable, bacteria will grow wildly.

When standing up, the water is easy to drain, and even if there is a little food residue, it is not easy to breed bacteria.

Washing dishes seems like a simple job.

It contains a lot of "technical" content

Many people actually "wash it wrong"!

Some bad dishwashing habits

Not only can't the dishes be washed clean

Instead, it breeds a lot of bacteria

Soak the bowl in water and wash it when you are free

After finishing a meal, many people want to take a break before washing the dishes. In fact, this is not a good habit. Soaking dishes for a long time will breed bacteria and produce odors. Especially for porridge bowls, if they are not washed immediately, they will become difficult to clean after air drying. If you can wash them before they are air dried, you may only need to rinse them lightly with water to clean them. It is simple and quick.

Dish towels are not disinfected or replaced

Using dishcloths to wipe dishes is also a health hazard. Dishcloths must be replaced regularly and disinfected.

We have done research and found that the number of bacteria in dishcloths is very high, so they must be sterilized at high temperature, and the dishcloth must be replaced every month or so, and the dishcloth must be used specifically for wiping dishes.

Apply detergent directly to the bowl

Some people think that "applying detergent directly on the bowl will have a stronger degreasing effect", but this not only wastes a lot of water, but also causes water pollution due to excessive use of detergent. If the bowl is not rinsed clean, the human body will ingest detergent, which will cause diarrhea and other gastrointestinal discomfort.

Recommendation: Drop a few drops of detergent into half a bowl of water, use a dishcloth dipped in the diluted water to scrub the dishes, rinse them and place them in another colander, finally rinse them with clean water and drain them.

Tableware is not sterilized

There are many methods of disinfection. The most commonly used method is high-temperature disinfection. Most bacteria and viruses can be killed by boiling it for more than 5 to 10 minutes.

If conditions permit, it is best to buy a sterilizer and put the dishes in it for high-temperature sterilization. This is one of the most effective ways to kill bacteria and viruses.

Note: It is not particularly recommended to use disinfectants for disinfection, because whether it is chlorine-containing disinfectant or other disinfectant, it is difficult to rinse it completely with clean water. If there is any residue, it will irritate the digestive tract.
