The National Health and Health Commission introduced that as the northern hemisphere enters winter, the global epidemic of new crown pneumonia is accelerating and the risk of transmission is further increasing. Recently, the positive detection rate of nucleic acid in imported cold chain food in China has increased significantly, and the number of provinces affected has increased.
The National Center for Food Safety Risk Assessment (NCFSRA) said that up to now, the sampling rate of imported cold-chained food and its outer packaging is 0.48 per 10,000, which is maintained at a relatively low level, and is mainly concentrated in the outer packaging of the food. In addition, relevant experts introduced issues of public concern such as disinfection, risk prevention and control of cold chain food.
1. How can the general public be well protected from the new coronary pneumonia epidemic in winter?
For the general public, to do to reduce the gathering, wear masks, wash hands regularly, maintain social distance; winter ventilation conditions are not good, to do a good job of home ventilation, in the public **** transportation, take the elevator and other poorly ventilated environments must wear a mask.
2. Spring Festival population flow, epidemic prevention and control situation?
After entering the winter, the global epidemic is becoming increasingly serious, in the past 11 months China has summarized a set of preventive and control measures, to be able to control the epidemic at the first time in the smallest possible range. Especially like the National Day, there are 600 million to 700 million people flow, there is no epidemic rebound. In the case of the Spring Festival, as long as there are no infected people in the crowd, there will be no major outbreaks.
Summarizing the experience of the past 11 months, China is confident of preventing a resurgence of the epidemic and a serious outbreak like the one in early 2020.
3. Why have the outer packages of imported cold-chain food tested positive for the new coronavirus in many places recently?
On the one hand, because many foreign countries are currently in the new crown outbreak, the surface of various objects, including food and its packaging may be contaminated by the new crown virus, and the new crown virus in the low temperature of the survival time is long, so imports of cold-chained food and its packaging may become a cross-border long-distance transportation to carry the new crown virus carriers.
On the other hand, various departments and localities have recently increased nucleic acid testing and sampling of imported cold-chained foods and their outer packaging for neocoronaviruses in accordance with the requirements of the State Council's Joint Prevention and Control Mechanism, and the probability of finding positives has increased with the increase in the frequency of testing, the frequency, and the scope of coverage.
Overall, the positive rate is also relatively low, up to now the national sampling and monitoring of the positive rate is 0.48 per 10,000, and mainly concentrated in the food packaging.
4. Imported frozen food can still be eaten without fear?
So far, low-temperature frozen food-related is mainly the circulation link caused by the spread, and did not find because of the consumption of these cold chain food caused by infection. However, the following points still need to be noted:
First, if you buy cold-chained food from informal channels, the surface of these food packages must be well sterilized to do their own protection.
Second, after touching these foods, do a good job of hand hygiene.
Third, it is best to eat cooked food during an outbreak.
Fourth, handle these foods in a way that prevents splashing and avoids contamination of the surrounding environment.
Fifth, after handling, the environment and surfaces should be cleaned and sterilized as necessary.
5. How to disinfect after contacting cold chain imported food?
Individuals who come into contact with these cold-chain foods can prevent possible contact transmission by sanitizing them.
First of all, good hand hygiene is needed. Wash your hands immediately after contact, there is a "six-step method" of hand washing, according to the "six-step method" of hand washing is usually enough. If you are not sure about washing your hands, you can add hand sanitizer. This is one of the most necessary measures.
Secondly, cooking utensils used for frozen foods that may come into contact with them, such as knives and cutting boards, should be cleaned in a timely manner. Splashes should be prevented during cleaning. At the same time for the knife, cutting board can be used to heat the method, with boiling water, boil a boil, soak in 60 degrees Celsius water for a period of time can be. You can dry them, spray 75% alcohol or 500mg/l, 1000mg/l chlorine disinfectant. Of course there are some table, you can also consider using alcohol, chlorine disinfectant wipe disinfection.
In addition, the residue should be collected and sent to the garbage collection point in time.
6. How should cold chain food workers be protected?
Recently, there have been cases of imported cold chain food handlers in Dalian, Qingdao and Tianjin being infected with the new coronavirus, which indicates that people of specific types of work may be infected with the new coronavirus due to frequent contact with cold chain items contaminated by the new coronavirus if protection is not in place in the specific environmental conditions. Therefore, in order to effectively do a good job of physical defense, human defense and other aspects of work, the State Council Joint Prevention and Control Mechanism issued the "cold chain food production and operation of the new coronavirus prevention and control of technical guidelines," "Guide" requirements on the cold chain of food practitioners in all aspects of the work, including loading and unloading, production, processing, transportation, sales, food and beverage, how to do a good job of prevention and control of the new coronavirus at each link has put forward specific requirements.
The requirement is for practitioners to strengthen daily protection, health monitoring, and active screening of nucleic acids. For example, for repeated contact with imported cold chain food high-risk groups, such as loading and unloading porters, before going on duty must wear a good working clothes and hats, wear disposable medical masks, gloves, but also wear goggles and face screen when necessary, in the whole process of carrying to prevent the skin from direct contact with the surface of the cold chain items, and wash their hands to disinfect immediately after the end of handling. Do not touch the mouth, eyes and nose before you take off your work clothes and wash your hands and disinfect them, but also strengthen the regular nucleic acid screening of practitioners.
