On November 25, the Joint Prevention and Control Mechanism of the State Council held a press conference on the cold chain of food and food safety in autumn and winter. Recently, the positive detection rate of imported cold chain nucleic acid foods has increased significantly, affecting more provinces. The products involved range from shellfish to beef and poultry products. The scope of imported virus-contaminated materials has expanded from cold chain foods to packaging. Therefore, consumers are very concerned about the safety of frozen food.

The “Daily Economic News” reporter asked at the press conference: “Is the current imported frozen food safe? Can I still eat it? How can I effectively avoid being infected by imported frozen food?”
Zhang Liubo, chief disinfection expert at the Chinese Center for Disease Control and Prevention and director of the Center for Infection Control and Disinfection at the Environmental Institute, responded that what we have seen so far is the circulation link related to frozen food. at low temperature, which is caused by the transmission and operation links. Infections caused by eating these cold chain foods were found.
On November 26, staff at the Shanghai Hongqiao Pinhui Healthy Food Hall cleaned frozen food containers with disinfectant, according to the Xinhua News Agency.

According to Zhang Liubo, consumers should not be too nervous about frozen foods.
In response to a question from a “Daily Economic News” reporter, he said that the surface of frozen food containers must now be disinfected and it is safe to touch these surfaces after disinfection.
On November 8, the Joint Prevention and Control Mechanism of the State Council issued the “Work Plan for Preventive and Comprehensive Disinfection of Imported Cold Chain Foods”, which clarified that after completing the new detection and Corona virus sampling as required, inspections, transportation, packaging and storage, wholesalers and retailers In other links, implement a preventive and comprehensive disinfection treatment before imported food from the cold chain comes into contact with the people in China for the first time.
Zhang Liubo also stressed that it should be noted that if you are buying some commercial products from abroad, the surface of these food packaging must be disinfected to protect itself. At the same time, after handling these foods, wash your hands and practice good hand hygiene. During the epidemic you have to pay attention, it is best to eat cooked food. Avoid splashing when handling these frozen foods to avoid contamination of the surrounding environment. After treatment, the environment and the surface should be cleaned and disinfected as necessary.
Li Ning, deputy director of the National Center for Food Safety Risk Assessment, also said that the new coronavirus is a respiratory virus that is transmitted mainly through respiratory droplets and close person-to-person contact, and the possibility of infection to through the digestive tract is very low. Although novel positive coronavirus nucleic acid has recently been detected in cold chain food and its outer packaging in many places, the overall positive rate is very low, mainly due to contamination of the outer packaging of food. Based on the epidemiological traceability analysis, the infected population is a high-risk population that repeatedly contacts the outer packaging of imported food from the cold chain in a specific environment, as carriers.
Confident to prevent the epidemic from returning
If consumers come into contact with imported food from the cold chain, how should it be disinfected?
Zhang Liubo pointed out that the first thing to do is practice good hand hygiene, wash your hands immediately after contact, and wash your hands according to the “six-step method.” If you are not concerned with washing your hands, you can add a hand sanitizer. This is one of the most necessary measures. Kitchen utensils that may come into contact with frozen food, such as knives and cutting boards, should be cleaned in time and splashing should be avoided during cleaning.
Zhang Liubo said that heating methods can be used for knives and cutting boards. It can be blanched and boiled in boiling water and soaked in 60 degree water for a period of time. Of course, after it dries, you can spray 75% alcohol or 500mg / l or 1000mg / l chlorine disinfectant to achieve the disinfection effect. Some counters may also consider using disinfectants that contain alcohol or bleach for wipe disinfection.
Zhang Liubo stressed that attention should be paid to collect the waste on time and send it to the garbage collection point on time. “If the frozen food garbage can be turned into a small package, it is better to send it on time.”
In addition, it will be the Spring Festival soon, and staff mobility will increase during the Spring Festival holidays, and some people are concerned about whether stricter epidemic prevention measures will be adopted as in the initial stage of the epidemic.
In this regard, Wu Zunyou, chief epidemiologist with the China Centers for Disease Control and Prevention, said that there was a large flow of 600 to 700 million people during the National Day and that there was no rebound in the epidemic. It is now winter and there will be a great flow of people during the Spring Festival. As long as there are no infected people in the crowd, there will be no major epidemic.
Wu Zunyou said that, summing up the experience of the past 11 months, we are confident of preventing a recurrence of the epidemic and preventing the emergence of a serious epidemic like the one at the beginning of the year. To achieve this, we must comprehensively apply scientific prevention and control measures. In short, they are scientific prevention and control, accurate policy implementation, concentrated effort and focus, so that prevention and control measures are “accurate and ruthless”, caught early, and the epidemic is minimized at the earliest. first rank.
