How unsanitary is it without chopsticks?
What's the difference between using public chopsticks and not using them? Recently, 1 1 experts from the Health Hazard Monitoring Institute and Inspection Center of Hangzhou CDC went to the restaurant to do an experiment!
The experimental group chose a nearby restaurant and ordered six dishes, namely: cold cucumber, salted shrimp, dry pot Agrocybe aegerita, fried asparagus, pickled octopus and spicy bullfrog.
They divide each dish into two parts, one with public chopsticks and the other without public chopsticks; In addition, a dish was specially ordered as a blank control.
Before eating, CDC staff took sterile gloves, disinfected tweezers with alcohol lamp and collected food samples for 40 minutes.
Then, it is the "brain-burning" eating session! Clamping the same dish must be done alternately with and without public chopsticks, and each time you eat it, you should "calculate" it in your mind, so as to ensure that the chopsticks touch the dish the same times.
After dinner, the CDC staff conducted another sampling. 19 Take food samples before and after meals.
After 48 hours of culture, the experimental results showed that the total number of colonies in the non-public chopsticks group was higher than that in the public chopsticks group.
What is even more unexpected is that the total number of colonies is so many times different! ! !
The total number of colonies in cold cucumber-"non-public chopsticks" group is nearly three times that in "public chopsticks" group.
Grilled Agrocybe aegerita-the difference in the total number of colonies between the two groups is 17 times!
Stir-fried asparagus-the difference between the two groups is nearly 18 times! !
Pickled octopus-an amazing 250 times! ! !

The expert in charge of testing said: if you don't use public chopsticks, on the one hand, you will spread the bacteria carried by your mouth and nose to the dishes through chopsticks. On the other hand, it will also lead to cross-contamination of bacteria carried by different dishes.
For example, chopsticks with cold cucumber and salted shrimp will lead to cross-contamination of bacteria between the two dishes.
Tips: Cold salad has not been cooked at high temperature, and the total number of colonies is generally more than that cooked at high temperature.
How much disease risk does a pair of chopsticks hide?
Of course, some people will suspect that I have never used public chopsticks in my life for decades, so there is no problem.
Sometimes, when there are problems, it is too late, or there are some problems, but you just don't find them.
1 Transmission of Helicobacter pylori
Helicobacter pylori, most of which were found by physical examination, may have no clinical symptoms, or may have clinical symptoms that have not been taken seriously. It is an important pathogenic factor of chronic gastritis and peptic ulcer, and is also related to the occurrence of gastric cancer.
Chopsticks will spread to people's stomachs when they are clamped. As a result, there will be a situation in which "one person tests pylorus and the whole family has it" and "the office often has dinner, and six people have five people infected".
The epidemiological survey of Helicobacter pylori infection among natural people in China published in Modern Digestion and Interventional Diagnosis and Treatment (20 10) involved more than 30,000 people in 9 provinces, municipalities and autonomous regions, and the total detection rate of Helicobacter pylori was 54.76%. In other words, more than half of China people have Helicobacter pylori in their stomachs.
When a table of people poke around in the dish with chopsticks they have smoked, the spread of germs may be inadvertently completed.
2. Causing the spread of respiratory infectious diseases
Recently, in many places in COVID-19, there have been many family gatherings or eating out.
Chen Jinjun, the chief physician of the Department of Infectious Diseases, Southern Hospital of Southern Medical University, introduced in the article "Prevention and control of epidemic situation cannot be relaxed, and it is recommended that many people use public chopsticks for meals" published in Guangzhou Daily on February 24th that although droplet transmission at close range is the main transmission route in COVID-19, the possibility of virus transmission through saliva-tableware-food-tableware cannot be ruled out.
COVID-19 may experience it once in a lifetime, but so does the annual flu, and there may be the possibility of saliva-tableware-food-tableware.
Hepatitis A, hepatitis E and herpes zoster ...
Many infectious diseases may spread quietly during meals. Guo Peng, chief physician of the Department of Hepatology, Xiyuan Hospital, Chinese Academy of Traditional Chinese Medicine, told Health Times reporter in July 20 14 that both hepatitis A and hepatitis E can be transmitted through oral cavity, and there are usually four weeks of infection (two weeks before onset and two weeks after onset), so we can really eat together.
Li Honglin, deputy director of the Center for Disease Control and Prevention in Zhabei District, said in April 20 17 that someone infected with herpes simplex virus may have itchy blisters on the corners of his mouth, just like "getting angry". And if there is no public chopsticks, it may be transmitted to others.
Don't let the use of chopsticks become a slogan!
After experiencing this epidemic, I hope to change some of our concepts and habits. At least in the use of public chopsticks, it is no longer a slogan.
Using public chopsticks or eating together does not mean losing friendship, which is not in line with traditional culture. Everyone is still eating at the same table and sharing food together, but there is an extra process of filling rice.
This process is also very simple to implement, such as: adding chopsticks or spoons to each dish; At home, meals are directly packaged into exclusive meals and drinking utensils for family members. This extra serving process ensures everyone's health.
