Photographed by Xinhua News Agency reporter Ren Chao Why does the imported cold chain frequently become the focus? Since the outbreak, many places have reported positive nucleic acid detection of imported cold chain food. Experts point out that cold chain food and packaging may become carriers of COVID-19 in the process of cross-border transportation. Wang Hui, Dean of the school of public health of Shanghai Jiaotong University, analyzed that in the imported epidemic caused by imported cold chain goods, infected persons involved in management, operation, loading and unloading and other positions. It was found that the daily life and work of infected persons had some intersection, including living together, eating together, sharing toilets, etc. Liu Jue, a member of Peking University's School of public health and National Expert Committee on New Coronavirus pneumonia, said that the longer the COVID-19 survives in the environment, the greater the risk of infection. "The low temperature environment can prolong the survival time of the virus. The COVID-19 observed at present can survive for about 21 days at low temperature." Liu Jue said. In addition, novel coronavirus pneumonia and asthma were collected by Liu Jue in the research group. The data showed that the lower the temperature, the higher the incidence of pneumonia. "Every time the temperature decreases by 1 ℃, the number of patients increases by 0.3%." Liu Jue said.

Photographed by Xinhua News Agency reporter Ren Chao What is the proportion of imported cold chain food on consumers' table? With the continuous improvement of living standards, consumers have higher and higher requirements for eating fresh and healthy. Cold chain logistics plays an important role in the storage and transportation of fresh products. Taking the purchase of Spring Festival New Year goods as an example, fresh "foreign new year goods" are popular year by year on many e-commerce platforms, and are favored by consumers. According to jd.com data, from January 9, 2022, when the new year's Festival opened to the eve of the lunar new year, the transaction volume of imported cherizi increased by 282% over the same period of the lunar calendar last year, the import of frozen and chilled shrimp increased by 200%, and the import of emperor crab increased by 162%. Taking meat as an example, according to the data of the National Bureau of statistics, the output of pig, cattle, sheep and poultry meat in China was 88.87 million tons in 2021. "The imported meat and peripheral products are 9.38 million tons, accounting for 10.6% of the output of pig, cattle, sheep and poultry meat in China, which constitutes an important part of consumers' table." Qin Yuming, Secretary General of the cold chain logistics professional committee of China Federation of logistics and procurement, said. Can imported cold chain transportation stop? "A consumer asked whether the import cold chain transportation could be stopped because of the epidemic risk of the import cold chain for many times. If the import cold chain transportation was stopped, it would have a great impact on the economy, industry, consumption and other aspects." Qin Yuming introduced that imported cold chain products, as an important supplement to the supply of relevant domestic categories, play an important role in balancing supply and demand in the domestic market and stabilizing prices. "Imported vegetables, fruits, livestock products and aquatic products are highly dependent on cold chain logistics. If the imported cold chain logistics is stopped, the relevant cross-border business will stagnate, a large number of resources such as port inspection warehouses, cold storages and freezers will be idle and wasted, and about 300000 employees of imported cold chain food will have nothing to do, which will have a great impact on the economy and industry, as well as both domestic and international Impact on the construction of recycling system. " Qin Yuming analysis. In addition, experts said that the categories and output of some domestic fresh agricultural products can not meet the daily needs of domestic consumers. Stopping the import cold chain logistics will have a great impact on the diversity of consumers' dining tables. Can imported cold chain products be purchased and eaten at ease? "In general, consumers are not at risk to infect COVID-19 by eating imported cold chain food." Liu Jue said that the WHO and FAO assessed the existing literature and data, and believed that consumers or the public were very likely to infect COVID-19 through contaminated media. "At present, there is no case report of infection due to eating cold chain food, including frozen food and refrigerated fruit." Liu Jue said. "At present, novel coronavirus pneumonia is the main risk factor for cold chain food infection. It is mainly in transportation, operation and other aspects. It is safe and effective to sterilize the surface of cold chain food packaging." Ke Rui, head of JD logistics cold chain pharmaceutical business, said. According to experts, after continuous practice, exploration, research and improvement, at present, the national multi department linkage has gradually formed a set of risk control measures for imported cold chain food, including killing protection, daily operation and management, epidemic related food screening and cold chain traceability system, through the introduction of a series of policy documents. According to Wang Hui, at present, all 31 provinces, autonomous regions and cities have built provincial imported cold chain food traceability management platforms, realized data docking and sharing with the national imported cold chain food traceability management platform, strengthened the collaborative linkage of cross departmental and cross regional traceability management, and improved the accuracy and timeliness of epidemic related food inspection and control. "For imported cold chain products through formal channels, consumers can buy them at ease." Qin Yuming said. What should we pay attention to when purchasing imported cold chain products? Experts suggest that when dealing with cold chain products, consumers can take alcohol or disinfectant to disinfect the outer packaging of products, and choose appropriate cleaning and killing methods according to the type of food materials. At the same time, wear masks and disposable gloves during disinfection and cleaning. Liu Jue suggested that everyone should maintain healthy eating and behavior habits. "For example, if you want to buy cold chain food in regular supermarkets or markets, do not buy cold chain food without obvious information sources; it is recommended to eat the food after it is cooked and cooked, and try not to eat raw and cold food, which will also help to prevent some other foodborne diseases." Liu Jue said. (Xinhua News Agency)
