The risk of contracting the virus from eating imported cold-chain foods is low

the global outbreak of new crown pneumonia has accelerated as the northern hemisphere enters winter. The number of countries of origin of imported cases outside China is increasing, and the risk of transmission is further increased. The spread of the epidemic is characterized by "from thing to person" and "from person to person".
At the same time, the recent import of cold chain food nucleic acid positive detection rate increased significantly, affecting more provinces, involving products ranging from marine products to livestock and poultry meat products, imported materials contaminated by the virus from cold chain food to containers.
this,
relevant departments of the Joint Prevention and Control Mechanism issued policy measures and technical guidelines to deploy and strengthen the import of cold chain food preventive and comprehensive disinfection, cargo source control, production and operation process prevention and control and protection of employees. Recently,
joint anti-control mechanism held a press conference to introduce the cold chain food management and winter food safety related situation.recently, many in the import of cold chain food and its packaging tested positive for the new coronavirus nucleic acid. In this regard, the deputy director of the National Food Safety Risk Assessment Center
explained that, on the one hand, because many foreign countries are currently in the outbreak period of the new crown, the surface of various objects including food and its packaging may be contaminated with the new crown virus, and the new coronavirus at low temperature survival time is long, so imported cold chain food and its outer packaging may become cross-border long-distance transport carrying the new crown virus carrier.
other hand, various departments and places in accordance with the requirements of the
joint prevention and control mechanism, increased the import of cold chain food and its packaging of new coronavirus nucleic acid detection and sampling efforts. As the frequency, frequency, and coverage of tests increase, the probability of finding a positive increases. This shows from the side that China's measures to strengthen physical defense are very effective, after increased monitoring and other measures to identify problems, timely response to the disposal, thereby reducing the risk of the spread of the new coronavirus.
" overall, the positive rate is relatively low. "
, the positive rate of national sampling and testing is 0.48 per 10,000, and mainly concentrated in food packaging.
since the discovery of cold-chain food packaging and outbreaks have a relatively large correlation,
joint prevention and control mechanism timely issued the "cold-chain food production and operation process of the new crown virus prevention and control disinfection technical guide."
" has not found infections caused by direct consumption of imported cold-chain foods. Zhang Liubo, chief expert in disinfection at the CDC and director of the Environmental Disinfection and Infection Control Center, said the current infections occur in the circulation of cryogenic frozen foods, such as unloading, handling and other operations. Do a good job of disinfection treatment, eat imported cold chain food, the risk is very low.The General Administration of Customs issued on November 9 the Implementation Plan for Preventive Disinfection of Imported Cold Chain Food Ports, which made specific deployments for preventive disinfection of imported cold chain food at ports, including clarifying the work requirements, operational procedures, disinfection technical specifications and supporting regulatory measures for preventive disinfection at ports.
According to the General Administration of Customs Import and Export Food Safety Bureau Director Bi Kexin introduced, the customs department is responsible for carrying out the monitoring and testing of imported cold chain food new crown virus in accordance with the provisions, organize and guide importers of cold chain food, customs inspection sites of the business units to do a good job in the port link of the import cold chain food container wall and cargo packaging preventive comprehensive disinfection work.
Since the program was issued to November 24 at 24 hours, the port link preventive disinfection of imported cold chain food packaging accumulated more than 1.6 million pieces, weight of more than 30,000 tons, disinfection scope includes the pumped imported cold chain food packaging, containers, air transport pallets, land transport container trucks, bulk fishing boats and so on.
some parts of the country have been found in the winter low temperature environment, container transport process has produced a cold chain-like effect, causing sporadic or even local clustering outbreaks.
To this, China CDC's chief epidemiologist Wu Zunyou said that into the winter, whether by air, land, sea, because the environmental temperature and cold chain system environment is the same, the relevant departments have been involved in international logistics as other transport as cold chain transport to strengthen management. Once there is environmental pollution, once someone infected, can be found in time, can be the first time to control the outbreak in the bud. This series of measures to prevent international logistics as a carrier of the virus to bring the epidemic into China, plays a very important role.winter, the global epidemic has become increasingly severe, with more than 600,000 confirmed cases often reported daily since November. In China, sporadic cases have recently been reported in Shanghai, Anhui, Tianjin and Inner Mongolia. The emergence of these sporadic cases gives the feeling that the virus is knocking on the door of the country and is about to break in. As a result, the world is facing a big test, and China is also facing a big test.
, Wu Zunyou said that in the past 11 months we have summarized a set of prevention and control measures, can be the first time to control the outbreak to a minimum. "In the face of a global outbreak, everyone should have a more objective and realistic expectation." "The occurrence of sporadic cases is a normal phenomenon under normal prevention and control, " he said. We have experienced and succeeded in the past 11 months. In particular, there was a large movement of 600 million to 700 million people on National Day, and there was no rebound in the outbreak. Now into the winter, followed by the Spring Festival personnel flow, as long as there are no infected people in the population, there will be no major outbreak. Inresponse to recent outbreaks, large-scale nucleic acid testing was carried out immediately after the outbreak. Some people have questions: Is this test necessary? Is it compliant with scientific protection requirements? Is it cost-effective?
, Wu Zunyou said, with the development of technology, more and more mature, has become a standard for the prevention and control of the new coronary pneumonia outbreak. After the outbreak, large-scale nucleic acid testing is very necessary, nucleic acid detection sensitivity is relatively high, soon be able to determine the scale of the outbreak. In this way, we have eaten a "heart-stopping pill."
detection of large-scale nucleic acids is scientific. "Large-scale testing generally uses a 1 to 5 mixed test, 5 people's samples put together a test, if it is negative on the past. If it is positive, then take a tube-by-tube test. Because the infection rate of the population is very low, in less than one in 10,000, the use of a one-to-five mixed testing model, can be found in a timely manner infected people, while being able to carry out large-scale, large-scale, cost-effective. Wu Zunyou said.
, it's also good for individuals. Wu Zunyou said nucleic acid testing is still the most effective way to detect early cases in a timely manner. Through nucleic acid testing, the tester himself will benefit. If positive is found, it can prevent the disease from becoming light to heavy, reduce damage to oneself, and prevent further transmission.
