　　On the 17th, a follow-up investigation was recently conducted on the official website of the Chinese Center for Disease Control and Prevention. The investigation involved a new type of coronary pneumonia epidemic in Qingdao. The new coronavirus was detected in positive samples of imported frozen cod carried by workers. virus. Announcing that they are separated. This is the first time that a new original coronavirus has been isolated in the outer box of the cold chain cover, and it has been confirmed that contact with the outer box contaminated by the new coronavirus can cause infection.

　　The Chinese Center for Disease Control and Prevention said that separating live viruses from Qingdao's cold-chain food packaging can enable the new corona virus to survive long-term under special cold-chain transportation conditions. He said this was the first confirmation outside. The new corona virus has the potential for long-distance cross-border imports using cold chain products as carriers. Under certain environmental conditions, the virus on the surface of the product may cause susceptibility to contact infection without effective protection. People at risk of infection are mainly employees of cold chain commodities. This finding indicates that while preventing infected persons from importing from abroad, attention should be paid to the risk of importing viruses from cold chain items contaminated by foreign viruses. The Chinese Center for Disease Control and Prevention stated that the risk of cold chain foods on the Chinese market being contaminated by the new coronavirus is very low. Recently, relevant Japanese authorities conducted a new coronavirus nucleic acid sampling test on cold chain foods. As of September 15, 2.98 million test results have been submitted in 24 states across the country. These included 670,000 cold chain food and packaging samples, 1.24 million employee samples, 1.07 million environmental samples, and only 22 food and packaging samples were submitted. A new coronavirus-positive nucleic acid was detected in this virus, the nucleic acid load of this virus is low, and no live virus has been isolated so far.

　　If ordinary citizens touch or eat cold chain food, what is the risk of infection? The Chinese Center for Disease Control and Prevention said the risk is low. Existing research and prevention and management measures show that the new coronary heart disease is not a food-borne disease, and no infection caused by eating has been found. So far, no cases of consumer infection due to contact with contaminated cold chain seafood have been found, and the risk of infection for Chinese consumers is very low. The main transmission route of the new coronavirus is still in close contact with respiratory droplets. At the same time, relevant Chinese authorities have strengthened the monitoring and disinfection of new corona viruses in imported cold chain foods. The public should keep clean and separate raw and cooked food. They can buy and eat imported fresh food as usual. The Chinese Center for Disease Control and Prevention said that items contaminated by the virus that survived certain conditions may infect vulnerable contacts without effective protection, mainly among employees in related industries. It reminds me that I have sex. The latest "New Coronary Pneumonia Prevention Plan (Seventh Edition)" issued by the State Council's New Coronavirus Pneumonia Prevention and Control Mechanism is for employees of cold chain food in various places. It requires daily personnel protection, health monitoring and active nucleic acid screening. Improve the environmental sanitation conditions of production, processing and trade, and reduce the risk of employees contracting the virus.

　　The Chinese Center for Disease Control and Prevention is a practitioner in this industry. He maintains close contact with cold chain products (such as those who handle, process and sell cold chain products) that may be contaminated by the new coronavirus in the workplace. To enhance the awareness of protection, it is recommended that you need to do daily protection to avoid direct skin contact with cold chain products that may be contaminated and do not take off work clothes that may be contaminated after contact with cold chain products. Wash your hands before disinfecting. Do not touch your mouth, nose or eyes before disinfection. Wash and disinfect hands immediately after the work is completed, and conduct regular nucleic acid screening.
