Hot Eight:Imported Cold Chain Foods-Difficulties and Key Points in Epidemic Prevention and Control

Dear offline and online guests and media friends, good afternoon!
My topic is about imported cold-chain food. Imported cold-chain food is also a topic of very high attention in 2020. Why is the attention so high? It is because imported cold chain food and its packaging may become carriers for long-distance cross-border carrying and transmission of the new coronavirus.
At present, many foreign countries are in the outbreak period of the new crown epidemic, and the surface of various objects, including food and its packaging, may be contaminated.
The new crown virus survives for a long time under low temperature conditions. As the temperature in winter decreases, not only cold chain food and its packaging, but all international transportation environments are similar to cold chain systems, and related items may be carried over long distances across borders And the carrier that spreads the new coronavirus. High-risk groups are mainly people who frequently come into contact with these potentially contaminated items and are not properly protected.
The overall pollution rate of imported cold chain food and its packaging is relatively low, and it is mainly concentrated in the outer packaging. Although the new coronavirus nucleic acid positive has been detected in imported cold chain food and outer packaging in many places recently, overall, the pollution rate is relatively low, and the main contamination is the outer packaging. As of November 25, 2020, the national cold chain food and packaging sample monitoring and sampling results organized by the National Health Commission showed that the pollution rate was 0.48 per 10,000.
Consumers are generally unlikely to have access to the outer packaging, and the probability is relatively small. Therefore, the infection rate of consumers is relatively low. The main reason is that if the protection is not in place, the risk of infection of exposed people may increase.
my country adopts strict prevention and control measures for imported cold chain foods to effectively prevent the risk of epidemic importation. The State Council’s joint prevention and control mechanism has also issued a series of related requirements and documents on strengthening cold chain food management. Everyone has paid attention to several important documents. Cold-chain food production and operation new crown virus prevention and control technology guide, disinfection guide, preventive comprehensive disinfection work plan of imported cold-chain food, and notice on the traceability management of cold-chain food. The documents are all about the very important national level requirements for cold chain food. At the same time, the relevant departments have also strengthened the disinfection of imported goods and containers, treating other transportation involving international logistics as cold chain transportation to strengthen management, strengthening entry inspection, entry disinfection and the operation requirements of related practitioners, starting from the source Protection.
First, the prevention and control of imported cold chain foods should focus on strengthening the frontier. Imported cold-chain food requires a series of links such as customs entry, transportation, warehousing, and sales to consumers. It has the characteristics of long circulation chain, wide range, and long time. In this process, the implementation of epidemic prevention and control measures is advanced, prevention and control The lower the effectiveness and cost, it is necessary to move forward and strengthen source control.
Second, food producers and operators should strictly implement the main responsibilities of epidemic prevention and control. Although the new crown pneumonia is not a food-borne disease, it will have an impact on food safety and put forward higher hygiene requirements for the safety of the entire food industry chain.
Food producers and operators should adopt more stringent hygiene management measures for personnel and production and operation; those engaged in cold chain food production and operation should follow the relevant requirements of the”Cold Chain Food Production and Operation New Coronavirus Pollution Prevention and Control Technical Guide” and other relevant requirements The main responsibility of prevention and control, strengthen the daily protection, health monitoring and active nucleic acid screening of employees, and protect and disinfect in all links of production, loading and unloading, transportation, storage, sales and catering services to ensure normalization of epidemic prevention and control Normal operations.
Third, the prevention and control of the epidemic must be done with”people” and”things”. At present, the spread of the epidemic shows the coexistence of”from material to person” and”from person to person”. Therefore, the prevention and control of the epidemic requires the simultaneous prevention of”people” and”things”. While blocking imported cases abroad, it is also necessary to strictly control the risks of importing through logistics channels, especially cold chain logistics.
Control from the source as much as possible, on the one hand, increase the inspection and quarantine of imported cold chain foods, and carry out active preventive and comprehensive disinfection work; on the other hand, strengthen the protection of occupationally exposed people and the active screening of nucleic acids; in view of the winter The environment of all international transportation is similar to the cold chain system. While strengthening the disinfection of imported items, practitioners should also protect them in accordance with the requirements of relevant standards.
