Another place! Yunnan Health Commission notified on July 16: As of July 14, Yunnan has carried out a new coronavirus nucleic acid test on 2,750 frozen vannamei shrimp-related samples, of which 3 nucleic acids were detected from the outer surface samples of the packaging box Positive.
Prior to this, at the press conference of the Joint Prevention and Control Mechanism of the State Council on the afternoon of July 10, Bi Kexin, director of the Import and Export Food Safety Bureau of the General Administration of Customs, introduced that the customs found 6 samples of the 227934 cold chain monitoring samples to contain the new crown virus. Among the 6 samples found to contain the new coronavirus, the number of product samples was 0, the number of inner and outer packaging samples was 5, and the number of environmental samples was 1.
In other words, in these tests, the product itself has not been detected to contain the new coronavirus. It is the product packaging and the environment in which the product is detected to contain the new coronavirus.
In fact, last month Academician Li Lanjuan proposed that the new crown virus can survive for a long time in low temperature environments. Customs should strengthen the comprehensive investigation of cold chain foods and trace the source of imported and exported materials that are positive. The above-mentioned test results also verified the expert's previous judgment.
Nucleic acid-positive samples were successively found in the cold chain monitoring samples, which also aroused everyone's attention to the cold chain.
Can the new coronavirus be spread in food through the cold chain? Li Xingqian, Director of the Department of Foreign Trade of the Ministry of Commerce, said in response to a reporter's question that whether the new coronavirus can be spread in food and food packaging through the cold chain is still inconclusive.
'From the report, the detection of new coronavirus nucleic acid on the outer packaging of imported seafood or the inner wall of the container can only say that it may have been contaminated during the processing and packaging process. This shows that the new crown epidemic is still relatively serious in some foreign countries.' China Liu Changyong, vice chairman of the Institute of Refrigeration and director of the Refrigeration and Freezing Professional Committee, analyzed.
He also emphasized that cold chain technology is an important measure to ensure food safety. The detection of the new coronavirus on the packaging of imported food from overseas is because the packaging of imported products has been contaminated. It is not that the new coronavirus is produced in the cold chain, nor can it be said that the cold chain Technology has contributed to the new coronavirus. Cold chain technology is a very important technology to ensure food safety and freshness. It can inhibit the growth and reproduction of microorganisms in food and prevent food from spoiling.
Liu Changyong said that there is no fundamental difference in product quality between imported seafood and domestic seafood. Moreover, compared with foreign countries, the domestic epidemic is well controlled, and the possibility of seafood packaging being contaminated is very small.
Since the spread of the new coronavirus has not been controlled in many countries, it has a tendency to continue to spread, and it is impossible for my country to directly ban the import of all frozen foods. It is particularly important to strengthen the quarantine of cold chain foods.
'The sample is positive for nucleic acid, so people don't need to panic about it.' But Changyong Liu also reminded that in the context of strict prevention of imported epidemics, this latest test result undoubtedly reminds local customs once again that they must take good care of imported cold chain food. National Gate'. At the same time, try to choose to import food from places where the new crown epidemic is slightly better controlled.
Experts also reminded that in order to avoid contact with the virus that may be contaminated on the outer packaging of frozen seafood, seafood can be packed in a separate shopping bag when purchasing. Before processing, you can use 75% alcohol to sterilize the seafood packaging, and wear disposable gloves when taking out the food. Frozen seafood should be cleaned and stored after buying back to avoid contaminating the refrigerator and other food. It is best to eat it all at once on the same day. In the process of processing frozen seafood, be sure to separate raw foods from cooked foods, and do not touch your eyes, nose or mouth with your hands. Finally, after processing frozen seafood, remember to disinfect the items that have been touched.
