What are the consequences of not using public chopsticks? Someone did a comparison, and the results were amazing…

“Public chopsticks and spoons” initiative

It has always been one of the hot topics in food culture,

So how necessary is it to use public chopsticks and spoons?

Some time ago

11 disease control experts did an experiment

Test with and without public chopsticks

Bacteria comparison after meal

Use “public chopsticks” and “non-public chopsticks” separately

The total number of colonies differs by a factor of up to 250

Some time ago, experts from the Health Hazard Monitoring Institute and Inspection Center of the Hangzhou Center for Disease Control and Prevention in Zhejiang Province conducted an experiment to test the use of public chopsticks and those without public chopsticks. The bacterial comparison of the experimental results is shocking.

This experimental group was tested by 11 disease control experts. The experimental site was in a restaurant. The dishes ordered were cold cucumbers, brine shrimp, dry pot tea tree mushrooms, fried asparagus, pickles Octopus and Spicy Bullfrog etc.

Each dish is divided into two portions, one plate with public chopsticks and one plate without public chopsticks, and sampled and preserved in advance.

In order to ensure scientificity, the 11 participants have all been trained to eat two sets of dishes that use public chopsticks and those that do not use public chopsticks.

Leave at least 25 grams of each dish at the end for a second sampling.

After careful and strict aseptic operation sampling, put it in a sterile sample bag and quickly store it in the sampling box for refrigeration. Everyone has been waiting for 40 minutes.

After the meal is completed, the collected samples are transported to the laboratory through the cold chain.

After 48 hours of incubation, the experimental results show: Comparing the total number of colonies in the rest of the dishes of the two groups of “public chopsticks” and “non-public chopsticks”, the “non-public chopsticks” one The total number of colonies in the group is all higher than that of the “public chopsticks” group!

What is even more surprising is that the total number of colonies is so different! ! !

Cooked Cucumbers – The total number of colonies in the “non-public chopsticks” group was nearly three times that of the “public chopsticks” group.

Dry pot tea tree mushrooms – 17 times the total number of colonies between the two dishes!

Sautéed Asparagus – The difference between the two groups is nearly 18 times! !

Octopus with pickled vegetables – an astonishing 250 times more! ! !

The expert in charge of the test said: If you don’t use public chopsticks, on the one hand, the bacteria carried in your mouth and nose will be transmitted to the dishes through the chopsticks. On the other hand, it will also lead to cross-contamination of bacteria carried by different dishes themselves.

For example, the chopsticks used for cucumber salad and the brine shrimp can lead to bacterial cross-contamination between the two dishes.

Tips: Salad dishes have not been cooked at high temperature, and the total number of colonies is generally higher than that of dishes cooked at high temperature.

Experts call for:

When dining out,

Bring your own chopsticks and spoons is encouraged

Here, experts remind that it is necessary to use public chopsticks and spoons. It has two “obvious” benefits:

One is cleanliness and disease prevention.

Using public chopsticks and spoons can prevent personal tableware from contacting public food during shared meals, reduce contamination of dishes, and reduce the risk of disease entering the mouth, especially gastric pylorus Transmission of foodborne pathogens such as Helicobacter and Hepatitis A virus. During the epidemic, avoiding mixing tableware can also reduce the risk of virus transmission to a certain extent.

The second is to reduce waste and improve catering.

Using public chopsticks and spoons can help everyone develop the habit of taking meals on demand and eating on demand. If you haven’t finished eating out, you can take it home with confidence. While reducing waste, it also cultivates a good trend of people’s environmental protection and conservation.

All in all, it is necessary to use public chopsticks and spoons, whether it is to prevent diseases from entering the mouth, to protect the health of family members, or to advocate a civilized catering.

The epidemic is an opportunity to strengthen guidance for changing our traditional Chinese eating habits. The key is to change the concept and understanding, and through the unremitting efforts of everyone, over time, make it a healthy lifestyle passed down from generation to generation.

That’s why experts reiterate: When dining out, bring your own chopsticks and spoons, and use restaurant utensils as public chopsticks and spoons.

When using public chopsticks and spoons, many people find it troublesome and easy to confuse. Experts also share their “house rules” with you:

When eating at home, you can use the meal-sharing system, where the prepared meals are directly distributed into the family members’ own meals and drinking utensils, and everyone just eats at the same table;


If meals and drinking utensils cannot be completely independent, at least develop the habit of using public chopsticks (public spoons) to pick up (take) each dish. When dining out, you should take the initiative to ask the store to provide one dish and one spoon (one chopstick).
