    China's Centers for Disease Control and Prevention said on its official website that it tested positive samples of imported frozen cod carried by workers to isolate live viruses during an investigation into the origin of the qingdao new crown pneumonia outbreak.
    this is the first time in the world in the cold chain food packaging isolated to the new coronavirus, and confirmed that exposure to the new coronavirus contamination of the outer packaging can lead to infection.
    does it mean to isolate a live virus? Dr. Lin Yuliang, director of the infection department of the Third Hospital affiliated with Sun Yat-sen University, explained in an interview with the Health Times, "In the past, the outer packaging detected is the virus nucleic acid, equivalent to the 'wreckage' of the virus, the live virus is more spread than the virus 'wreckage', not the live virus, it is difficult to bind to the cell's recipient, so it is difficult to invade the human body."
    "Why haven't you been isolated to a live virus before and have an infected person?" "Patients infected with the new coronavirus through contact with cold-chain foods are still alive at the time of early exposure, but have not been detected before, but after the subsequent detection, it is not a live virus, it is only the virus 'wreckage', nucleic acid is a component of the virus.
    ," Lin said.
    you still be able to buy frozen seafood? For the average person, there is no need to be nervous at all, the CDC said, the general public contact or eat cold chain food infection risk is very low.
    under certain environmental conditions, viruses that survive on the surface of items can cause infection in susceptible contacts without effective protection, and the population at risk of infection is mainly cold chain article practitioners.
    July 22, Dalian City, Liaoning Province, a new confirmed case of local new crown pneumonia, this is one of the first cases to be found to be positive nucleic acid test, Shi a male for a marine products processing enterprise employees, the enterprise engaged in import and domestic aquatic products processing, refrigeration and other business.
    the outbreak in Qingdao is traced back to Qingdao Port on September 24 identified two asymptomatic infected people Dong and Chen.
    are both loading and unloading workers of Qingdao Port Corporation.
    the focus of epidemic prevention and control has shifted to "people, things and prevention" in the disease control said that the discovery also suggests that in the prevention of overseas infected people input at the same time, need to pay attention to the virus contaminated cold chain items outside the virus input risk.
    October 16, the Office of the State Post Office issued the "Recommendations on the Production Practices of the Postal Express Industry during the Epidemic Prevention and Control (Sixth Edition)", proposing that the Border International Mail Exchange Bureau (exchange station), border express processing sites and other international mail express processing sites to strengthen disinfection, ventilation and other work, strictly prevent overseas outbreaks, especially high-risk countries and regions through the delivery channel input.
    the outbreak prevention and control of the Autumn and Winter Festival need to focus on imported cold-chain food and cross-border express delivery? Lin said, not only in autumn and winter, each season should pay attention to strictly guard against international logistics, because international logistics express items in a sealed state, will not be exposed to sunlight, ultraviolet light and other external environment, can survive longer, especially cold chain food, because the cold chain itself in the frozen environment, in a low temperature situation, so every season to pay attention to.
    Lin pointed out that the survival of the virus is related to temperature, humidity, but not the main factors, but the virus in the cold chain of this low temperature environment, survival time is indeed longer.
    how long it will take to survive in a cold chain environment, and there is no accurate data for the time being.
    , the focus of China's new crown epidemic prevention and control has shifted from "people prevention" to "people and prevention".
    September 7, Zhejiang Province, the new coronavirus pneumonia epidemic prevention and control leading group office pointed out that after May 1, 2020 imports of incremental cold-chain food, must be on the packaging of its products on the "cold-chain food traceability code."
    September 28, the Beijing Municipal Bureau of Commerce informed the relevant import and export enterprises to strengthen the prevention and control of overseas sources, take the initiative to avoid the import of cold-chain food from areas with severe outbreaks, take effective measures to do a good job of imported food alternatives.
    Lin Yuliang reminded that we should try to avoid Haitao, buy goods in areas where the situation of foreign outbreaks is severe.
    Through e-commerce, micro-commerce and other channels to buy fresh products, express packaging such as unsterilized do not bring into the room, contact with the outer packaging and fresh food should wash their hands in time, avoid touching the mouth, nose and eyes and other places.
    addition, the food is cooked through to ensure food safety.
