Chinanews.com, November 25. Recently, many places have been tested positive for the new coronavirus nucleic acid in imported cold chain food and its outer packaging. Why does this phenomenon frequently occur?
Li Ning, deputy director of the National Food Safety Risk Assessment Center, explained two main reasons.
The State Council’s Joint Prevention and Control Mechanism held a press conference today. Responsible comrades and experts from the General Administration of Market Supervision, General Administration of Customs, China Centers for Disease Control and Prevention, and National Food Risk Assessment Center attended to introduce cold chain foods and the safety of autumn and winter foods, and answered reporters ask.
Li Ning said, on the one hand, because many countries abroad are currently in the outbreak of the new crown, the surface of various objects, including food and their outer packaging, may be contaminated by the new crown virus, and the new crown virus survives for a long time at low temperatures, so it is imported. Cold-chain food and its outer packaging may become carriers for cross-border long-distance transportation carrying the new coronavirus.
On the other hand, in accordance with the requirements of the State Council’s joint prevention and control mechanism, various departments and localities have recently increased the detection and sampling of imported cold chain foods and their outer packaging for new coronavirus nucleic acid. As the frequency, frequency and coverage of the detection increase, the probability of finding a positive Just increase.
Li Ning pointed out that this also shows from another aspect that the measures taken by my country in strengthening physical defense are very effective. After increasing monitoring and other measures, problems are found, and timely response and treatment are carried out to reduce the risk of the spread of the new crown virus.
In general, the positive rate is relatively low. So far, the positive rate of random inspections across the country is 0.48 per 10,000, and it is mainly concentrated in food packaging.
