During the meal outside, do the tableware be used before?

When dining abroad, you may have seen or practiced such a "pre -meal ceremony" for yourself: tore the tableware packaging, pour hot water, wash and cup the chopsticks and dishes ...

Many people think that the tableware outside is unsanitary, and the hot water has a disinfection effect. So the question is, is this method useful?

Is a dining tool hygienic?

Hygiene is not hygienic. In addition to visible dirt, it is more important to have pathogenic bacteria.

"GB 14934-2016 National Standard Disinfection Meal (Drink)" stipulates that "the colonic flora and Salmonella must not be detected."

In recent years, the detection rate of Salmonella has a low detection rate. Let's take a look at the more common colonobacteria.

(1) The results of the sampling inspection of the Shanghai Market Supervision Department

In March 2021, Putuo District notified that 6 batches of catering utensils were unqualified, and unqualified projects were large intestinal flora;

In May 2021, Baoshan District notified 150 food and beverage tools for random dining units, of which 5 were unqualified. All unqualified items were instructed (total colonies, colonic flora);

In June 2021, Huangpu District notified 9 catering units on the tableware to detect the colonic flora.

(2) Related investigation and research

(3) Internet report

There are also reports on the detection of the large intestinal flora in the online celebrity Japanese ingredients and well -known hot pot restaurants.

Taken together, the microbial pollution of catering utensils is generally acceptable, but there are still unqualified situations. In most cases, direct use problems do not cause disease. Although occasionally may cause abdominal pain, gastrointestinal discomfort, and severe symptoms such as diarrhea, vomiting, most people may not notice it. Instead, it is considered to eat too spicy or cold drinks, which stimulates the gastrointestinal tract.

Can I disinfect with hot water?

We analyze from two aspects: thermal and mechanical effects.

(1) Thermal effect

Common intestinal infectious diseases can be transmitted through unclean tableware, such as hepatitis A virus, which requires up to 5 minutes at 100 ° C.

After the family daily daily drinking utensils are boiled and disinfected, it should be kept for more than 10 minutes after the water is boiling, and the tableware needs to be completely immersed in the water. The hot water provided by the restaurant is generally less than 100 ° C, let alone just rushing to the area for more than ten seconds. From a professional perspective, the role is relatively limited and cannot achieve the purpose of sanitary disinfection.

(2) Mechanical effect

In addition to thermal effects, it can also use mechanical effects to remove some microorganisms and flush some washing residues. However, due to short time and no cleaners, sterilization and disinfection effects are very limited.

Micro -biological washed off the tableware at most, but it is impossible to kill them. It can only be said that it is slightly useful.

Three before using catering tools should be "two -see and one smell"

1. See if there is any mildew

Especially wood and bamboo chopsticks are more likely to mold.

2. See if there are stains

See if there are debris, residues and other foreign bodies on the tableware.

3. Whether it smells without smelling

I heard whether there is a pungent, irritating, and abnormal smell.

If the above situation is existing, it is useless to span, and it is the right way to change the new tableware directly!

Is it necessary to bring your own tableware?

For most people, it is not necessary. For people with immune -related diseases or allergic diseases, infants and young children, it is recommended to go out with tableware.
