Can I still choose imported cold chain food for the New Year?

Tomorrow is New Year's Eve, and while the family is happy, "good fortune" must be indispensable

In response to everyone’s concerns, Jiang Rongmeng, deputy dean of Beijing Ditan Hospital and chief physician of the Infection Center, said that it is right for the public to be safe in purchasing New Year’s products, but there is no need to waste food due to choking, as long as the corresponding protective measures are taken when purchasing and handling food.

Why are imported cold chain foods repeatedly "positive"

The cold chain for the food refers to the processing, storage, transportation, distribution and retailing of perishable food after it is purchased or harvested from the place of origin (all links are always in the low temperature environment necessary for food, Ensure food quality and safety, reduce losses, prevent pollution), and finally reach the special supply chain system in the hands of consumers

Generally speaking, foods that may require a cold chain include the following categories:

Primary agricultural products: vegetables and fruits; meat, poultry, eggs; aquatic products; flower products

Processed food quick-frozen food; packaged cooked food such as poultry, meat, and aquatic products; ice cream and dairy products; fast food raw materials

Special commodity medicines, such as vaccines

Jiang Rongmeng introduced that China currently manages the entire chain of cold chain foods.

On the one hand, because many countries are still in the epidemic period of the new crown epidemic, or even the high-incidence period, the number of infections is large, and most of the patients are mild, ordinary, or even asymptomatic

Will you be infected if you come into contact with contaminated food packaging?

The source of infection of the new coronavirus is mainly confirmed cases and asymptomatic infections of the new coronavirus.

According to Jiang Rongmeng, contact transmission means that people touch items contaminated by the virus through their hands, and then touch the mouth, eyes, nose and other parts without washing their hands, thereby indirectly bringing the virus into the human body

Up to now, the foods that have tested positive for the new coronavirus nucleic acid include cherries, milk dates, ice cream, hairtail, beer, shrimp, hanami, bean buns, etc.

What needs to be clarified here is that the positive nucleic acid of the food and outer packaging involved does not mean that there is a "live virus", and it may just be a non-infectious viral nucleic acid component

The new coronavirus can invade multiple systems and organs, including the respiratory system.

Therefore, as long as precautions are taken, imported cold chain foods such as fish, shrimp, meat, and fruits can be purchased and eaten

Purchase and cook these precautions

The end of the cold chain is in the family and in the individual, and the "virus risk" has to be guarded against

1.

2.
To purchase imported cold chain food, go to a regular supermarket or market, and check the "four certificates" such as the traceability certificate, the entry cargo inspection and quarantine certificate, the nucleic acid test certificate, and the disinfection certificate
.
Resolutely refrain from buying imported cold chain food without a certificate of conformity or buying cold chain food online
.
If you purchase overseas frozen food online, you must pay attention to the customs food quarantine information and disinfect the outer packaging
.

3.
When buying cold chain foods, you should wear a mask correctly.
At the same time, it is recommended to use disposable gloves or wrap your hands with a plastic bag before choosing.
Avoid direct contact with the food and its packaging surface with your hands
.
Be careful not to think that you can touch everywhere with gloves
.
Gloves cannot replace hand hygiene .

4.
Wash your hands promptly and correctly after touching cold chain food and its packaging, and do not touch the mouth, nose, eyes and other parts before washing your hands
.

5.
When cooking cold chain foods, keep in mind the principles of keeping clean, separating raw and cooked food, cooking and cooking thoroughly, maintaining a safe temperature, and using safe water
.
In particular, the raw and cooked food should be separated.
The containers, knives, and cutting boards used in the processing of frozen fresh food should be placed separately, and cleaned and disinfected in time.
They should not be mixed with the utensils used to process directly ingested food to prevent cross-contamination
.
After washing or touching frozen frozen food, wash your hands before touching cooked food
.

6.
If not eaten on the day, cold chain food must be stored separately from cooked food
.
It is recommended to remove the original packaging and store the stored food in separate bags in the freezer compartment of the refrigerator
.

7.
Cooking food should be cooked thoroughly, avoid eating raw, half raw, soaked in wine, vinegar or salted and eaten directly
.

8.
The kitchen should be ventilated and cleaned regularly, and the environment and tableware and cooking utensils should be disinfected when necessary
.

9.
Put the processed garbage (including food residues, outer packaging, etc.
) into the garbage bag, tie it tightly, and discard it safely in accordance with the garbage classification requirements
.

10.
After eating cold chain foods, if symptoms such as fever and diarrhea occur, go to the fever clinic in time and actively inform the doctor of the eating time, food types, and sources of ingredients to assist in diagnosis and treatment
.

Wear disposable gloves when receiving overseas parcels

The new coronavirus likes a cold environment, the lower the temperature, the longer the survival time
.
A lot of cargo transportation in winter also produces an environment similar to cold chain transportation, so in addition to cold chain, other goods involving foreign countries should also be guarded against
.

Jiang Rongmeng suggested that you wear disposable gloves when you receive overseas express, and do not move too much when opening the outer package to avoid splashing
.
After opening the box or bag, fold it back into the trash bag, then clean your hands and take out the express items
.
Items that can be disinfected with alcohol are recommended to be wiped and disinfected with alcohol wipes
.

Respiratory tract transmission, digestive tract transmission, blood transmission, etc.
, are actually spread through contact
.
Therefore, to prevent the new coronavirus, an important principle is "avoid contact
.
" If it is judged that the items in contact may have a higher risk, you can choose the alcohol spray disinfection method.
After spraying, let it stand for 20-30 minutes before touching it, which can effectively prevent the spread of the virus

special reminder

Few meals during the Spring Festival to avoid "asymptomatic"

Chinese people enjoy the Spring Festival, but also pay attention to popularity
.
In previous years, gatherings with friends and family was an essential social event, but this year everyone still has to manage their mouths and control their legs
.

During the epidemic, due to the presence of asymptomatic infections, the risk of new coronavirus infection is difficult to eliminate
.
If you happen to have close contact with them, especially if you participate in a dinner party where you need to remove your mask, then the new coronavirus is very easy to invade your body through close droplet transmission
.
This is not alarmist.
The recent clusters of epidemics are all caused by gatherings or attending wedding banquets
.

Jiang Rongmeng reminded that even close relatives, neighbors and acquaintances, in theory, large-scale dinner parties may not be safe
.
During the Spring Festival, communication should not be confined to the dinner table to express.
It is also a good choice to go to a park, talk on the phone, or send a WeChat
.

A few days ago, the Beijing Municipal Bureau of Commerce announced the "Guidelines for Dining at Catering Business Places", advocating citizens to reduce unnecessary dining activities during the Spring Festival
.
If you must have a dinner together, try to control the dinner time within 2 hours, try to control the number of people under 10 people, wash your hands before meals or use quick hand sanitizers, use public spoons and chopsticks, do not clink glasses when toasting, and leave your seat or private room.
Wear a mask
