Original title: This way to wash dishes, bacteria increased by 70 times! Eat it all into your stomach...
In life
Many people have this habit at home
The washed dishes and plates are stacked together
Take it out of the cupboard the next day and use it
But recently a friend said
Such habits are not good
This may cause secondary contamination of the dishes
Is this statement true?
A trial
Previously, the Household Appliance Research Institute did a set of experiments, which set up two sets of comparisons. The tester first disinfected the tableware, coated the surface of the tableware with sterile broth, and then divided the tableware into two groups, one of which was washed and stacked directly into the cupboard for storage, and the other group was washed and placed on the shelf and placed in a ventilated place.
After three days, the comparison showed that the total number of colonies on the standing tableware was 8000cfu/set, which met the relevant hygiene standards of the mainland, while the number of bacteria stacked on the shelf was 560,000cfu/set, which was 70 times that of standing.
The difference in colony levels of bacteria is so large
There are so many bacteria on it
What health risks can be caused to our bodies?
In fact, the kitchen is our health dead end, if the dishes are not placed properly or some do not pay attention, there may be some bacteria, virus breeding, the impact on our body is very large.
Acute effects in the short term: for example, some pathogenic bacteria, the most common pathogenic E. coli, Salmonella, such as norovirus, rotavirus, these may cause our acute gastroenteritis, vomiting and diarrhea and even dehydration, shock, life-threatening.
Long-term effects: Long-term intake of mold may contain a class of carcinogens such as aflatoxin, long-term exposure may cause cancer, and even studies have shown that aflatoxin has a certain relationship with liver cancer, stomach cancer, and esophageal cancer.
In addition, the bowl chopsticks are also the vector of Helicobacter pylori transmission, and Helicobacter pylori infection has a certain relationship with many stomach diseases, stomach ulcers and even stomach cancer.
Therefore, the health problems in the kitchen must be paid attention to, and the disinfection of tableware must be done well, including when storing, we must also pay attention to disinfection to prevent the breeding of bacteria or viruses.
How the dishes properly store bacteria to breed requires several necessary conditions
First: nutrients are needed
Second: the right temperature
Third: Be sure to have moisture
No matter how we wash our dishes or dishes, they cannot be washed very clean, and even a little food residue can be used as nutrients for bacteria. If you stack it, there is a lot of water, and the temperature of the room is suitable, the 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.
Cleaning bowls is a seemingly simple task
There is a lot of "technical" content in it
Many people have actually "washed the wrong"!
There are also some bad dishwashing habits
Not only can you not really wash the dishes and chopsticks
Instead, a lot of bacteria are bred
Soak the bowl with water and wash it when it's free
Just after eating, many people want to rest for a while and then wash the dishes, in fact, this is not a good habit. Bowls and chopsticks will nourish bacteria and have a peculiar smell after being soaked for a long time. In particular, the bowl containing porridge, if not cleaned immediately, becomes difficult to clean after air drying. If you can clean it before it dries, it may be clean with just a gentle rinse of water, which is simple and fast.
The dish cloth is not sterilized and not replaced
Wiping with a dish cloth is also a health hazard, and the dish cloth must be replaced regularly and must be disinfected.
Because we have done research on the dish cloth, its number of bacteria is very high, so it must be disinfected at high temperature, and a month or so must change a dish cloth, and the dish cloth must be specially used to wipe the bowl.
Detergent is applied directly to the bowl
Some people think that "detergent is more effective when applied directly to the bowl", but this not only wastes a lot of water, but the abusive detergent will also cause water pollution. Once the irrigation is not clean, the body will cause diarrhea and other gastrointestinal discomfort after ingesting detergents.
Recommendation: Drop a few drops of detergent into half a bowl of water, brush the dishes with a dishwashing cloth dipped in diluted water, rinse and place in another leaky basket, and finally rinse with clean water and control dry.
The cutlery is not sterile
There are many disinfection methods, the most commonly used method is high temperature disinfection, boil it for more than 5 minutes to 10 minutes after most of the bacteria, viruses can be killed.
If conditions permit, it is best to buy a disinfection machine and put the dishes and chopsticks in the high temperature disinfection, which is one of the most effective ways to kill bacteria and viruses.
Note: Disinfectant is not particularly recommended, because whether it is chlorine-containing disinfectant or other disinfectant, it is difficult to rinse completely with water, and if there is residue, it will irritate the digestive tract.
