Pig head contaminates elbow, new coronavirus cold chain spread is hard to prevent

On November 24, the news of the two major sources of new crown infection "cases solved" swept the screen

Recently, the positive detection rate of nucleic acid in imported cold chain food has increased significantly, and the number of affected provinces has increased, involving products ranging from seafood to livestock and poultry meat products, and the scope of imported materials contaminated by viruses has expanded from cold chain food to containers

So, how to sterilize the cold chain to be safe? Will there be a risk of infection to the public if a product that tests positive is accidentally left on the market? Can cold chain food be eaten?

In response to these issues of public concern, the Joint Prevention and Control Mechanism of the State Council held a press conference on November 25 to introduce cold chain food and food safety in autumn and winter

The cold chain becomes a "carrier", bringing the virus into the country

At the press conference, Li Ning, deputy director of the National Center for Food Safety Risk Assessment, reminded that many countries are in the outbreak period of the new crown epidemic, and the surface of imported objects may be contaminated by the new coronavirus.

For the public, in the face of the most severe situation, the simplest method is often the most effective - guarding the "last door" around you

"Individuals who come into contact with these cold chain foods can prevent possible contact transmission through disinfection

How reliable is the cold chain disinfection?

Cold chain food has been standardized and sterilized according to relevant specifications from the moment it enters the country

In the port link, Bi Kexin, Director of the Import and Export Food Safety Bureau of the General Administration of Customs, introduced that the General Administration of Customs issued the Work Plan for Preventive Comprehensive Disinfection of Imported Cold Chain Foods issued by the Joint Prevention and Control Mechanism of the State Council on November 8 and issued on November 9.

In terms of production and operation, the Joint Prevention and Control Mechanism of the State Council released the Technical Guidelines for the Prevention and Control of Novel Coronavirus in the Production and Operation of Cold Chain Foods in a timely manner, giving technical guidance on the disinfection of the packaging surfaces of low-temperature cold chain food at room temperature

In the tracing process, Chen Xu, the market inspector of the Food Management Department of the State Administration for Market Regulation, introduced that after receiving the information notification, the market supervision department immediately organized a comprehensive inspection of the same batch of products with positive nucleic acid tests, and urged relevant food production and operation.

　　"We have also organized and developed the 'Imported Cold Chain Food Traceability Platform', which connects to local traceability systems in real time, quickly determines the product circulation path and scope of influence, and is gradually realizing the full chain information traceability

　　Therefore, products that test positive will be quickly traced to the source with the help of information technology, and the cleaning and disinfection of storage sites, production and processing equipment, etc.

　　Disinfection in the cold chain is still a problem to be solved

　　"For disinfection of food surfaces in low-temperature cold storage, related technical methods are still being researched

　　Because the disinfection ability of conventional disinfectants is significantly reduced at low temperatures, common disinfection methods will fail

　　Cold chain food can be eaten, but pay attention to these points

　　"At present, no new coronavirus infection caused by direct consumption of these cold chain foods has been found

　　Cold chain food can be eaten, but experts believe that it is necessary to keep in mind the "five points" of food safety in the specific processing and cooking process, that is, keep clean, use safe water and raw materials, separate raw and cooked, cook thoroughly, and maintain a safe temperature of food

　　"We are now disinfecting the surface of frozen food packaging, and it is safe for consumers to touch these surfaces after disinfection
.
" Zhang Liubo said, of course, there are a few points to pay attention to: First, if you buy from a non-regular channel, and It is some overseas shopping products.
The surface of these food packaging must be disinfected and protected
.
Second, do good hand hygiene after touching these foods
.
Third, it is best to eat cooked food during the epidemic
.
Fourth, avoid splashing when handling food and avoid contamination of the surrounding environment
.
Fifth, after the treatment, the environment and surfaces should be cleaned and disinfected as necessary
.
