Every time the dishes and dishes are washed at home, they are stacked together
Take it out of the cabinet the next day and use it again
Recently, a friend said that this habit is not good
May cause secondary contamination of dishes
Is this statement true?
An experiment
Previously, the Home Appliances Research Institute conducted a set of experiments, which included two sets of comparisons. The experimenter first disinfected the tableware and coated it with sterile broth. Then, the tableware was divided into two groups. One group of dishes was washed and stacked directly in a cupboard for storage, while the other group was washed and placed upright on a shelf in a well ventilated area.
Three days later, the comparison showed that the total number of bacterial colonies in standing tableware was 8000cfu/set, which met the relevant health standards of China. However, the number of bacteria stacked on top of it was 560000cfu/set, which is 70 times higher than that in standing tableware.
The difference in bacterial colony levels is so significant
There are so many bacteria on it
What health risks will it pose to our bodies

In fact, the kitchen is our hygiene blind spot. If the bowls and plates are placed improperly or carelessly, there may be some bacteria and viruses breeding, which has a great impact on our body.
Short term acute effects: 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, shock, and life-threatening conditions.
Long term effects: Long term ingestion of mold may contain carcinogens such as aflatoxin, which can cause cancer upon long-term exposure. Some studies even suggest that aflatoxin is associated with liver cancer, gastric cancer, and esophageal cancer.
In addition, bowls and chopsticks are also carriers of Helicobacter pylori transmission, and Helicobacter pylori infection is related to many stomach diseases, ulcers, and even stomach cancer.
So health issues in the kitchen must be taken seriously, and tableware must be disinfected properly, including during storage to prevent the growth of bacteria or viruses.
How to store bowls and plates correctly
Firstly, it requires nutrients
Second: Suitable temperature
Thirdly, there must be moisture
No matter how we wash our dishes or bowls, they cannot be washed very clean. Even a small amount of food residue can serve as a nutrient for bacteria. If placed on top of each other, a lot of water accumulates and the room temperature is suitable, bacteria will grow wildly.
After standing up, the water is easy to drain, and even a little food residue is not easy to breed bacteria.
The seemingly simple task of washing dishes
It contains a lot of "technical" content inside
Many people actually "wash the wrong"!
There are also some bad dishwashing habits
Not only can't you really clean the dishes
Instead, it breeds many bacteria
//Soak the bowl in water and wash it when it's free
Just after dinner, many people think of taking a break before washing dishes, but this is not a good habit. Bowls and chopsticks soaked for a long time can nourish bacteria and have a strange smell. In particular, if the bowl containing Congee is not cleaned immediately, it will become difficult to clean after air drying. If you can clean it before air drying, you may just need to lightly rinse it with water, which is simple and fast.
//Dishwashing cloth not disinfected and not replaced
Using a bowl wiping cloth is also a health hazard, and the cloth must be replaced regularly and disinfected.
Because we have conducted research on dish cleaning cloths, they have a very high number of bacteria, so it is necessary to disinfect them at high temperatures. Moreover, it is necessary to change the dish cleaning cloth around a month, and the dish cleaning cloth must be specifically used for cleaning dishes.
//Apply detergent directly to the bowl
Some people think that "directly applying detergent to the bowl has a stronger effect on removing oil stains", but this not only wastes a large amount of water source, but also causes water pollution through misuse of detergent. Once not rinsed thoroughly, ingestion of detergent by the human body can cause gastrointestinal discomfort such as diarrhea.
Suggestion: Drop a few drops of detergent into half a bowl of water, use a dishcloth dipped in diluted water to brush the bowl, rinse, and place in another drain basket. Finally, rinse with clean water and let dry.
//Tableware not disinfected
There are many disinfection methods, and the most commonly used one is high-temperature disinfection. After boiling it for more than 5 to 10 minutes, most bacteria and viruses can be killed.
If conditions permit, it is best to buy a disinfection machine and put the dishes inside for high-temperature disinfection. This is the most effective way to kill bacteria and viruses.
Attention: It is not particularly recommended to use disinfectants for disinfection, as whether it is chlorine containing disinfectants or other disinfectants, it is difficult to completely rinse them with clean water. If there is residue, it will stimulate the digestive tract.
Health Tips
1. Placing tableware upright is not easy to breed bacteria.
2. Do not use water to soak the bowl; Don't wait until you're free before washing; Do not apply detergent directly to the bowl.
3. Dishwashing cloths should be disinfected at high temperatures and replaced with a new one around a month.
4. Disinfecting dishwashers can effectively sterilize or boil tableware for more than 5-10 minutes.
