Imported food packaging is contaminated, experts call for -
Don't negate cold chain technology because of detection of new coronavirus
Another place! The Yunnan Health Committee notified on July 16: As of July 14, Yunnan had carried out a new coronavirus nucleic acid test on 2,750 frozen samples of white shrimp, of which three nucleic acid samples were positive from the outer surface of the packaging.
Earlier, at the press conference held by the Joint Defense and Joint 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 6 of the 227,934 cold chain surveillance samples contained new coronavirus. Among the 6 samples found to contain new coronavirus, the number of product samples is 0, the number of inner and outer packaging samples is 5, and the number of environmental samples is 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 new coronavirus is detected.
In fact, academician Li Lanjuan proposed last month that the new coronavirus can survive for a long time in a low temperature environment, and the customs should strengthen the comprehensive investigation of cold chain food, and at the same time trace the traceability of imported and exported materials that are positive. The above test results also verify the expert's previous judgment.
Numerous positive samples of cold chain monitoring samples have been detected, which also aroused everyone's attention to the cold chain.
Can the new coronavirus spread in food through cold chain? In response to questions from reporters, Li Xingqian, director of the Department of Foreign Trade of the Ministry of Commerce, said whether the new coronavirus can be spread in food and food packaging through the cold chain method, it is still inconclusive.
"According to reports, the detection of new coronavirus nucleic acid positive in the outer packaging of imported seafood or the inner wall of the container can only be said that it may be contaminated during the processing and packaging process, which shows that the new crown epidemic situation in some foreign countries is still relatively serious." China Liu Changyong, deputy chairman of the Refrigeration Society and director of the Refrigeration and Freezing Committee, said.
He also emphasized that cold chain technology is an important measure to ensure food safety. The detection of new coronavirus from overseas imported food packaging is because the packaging of imported products is contaminated. It is not that the new coronavirus is produced in the cold chain, nor can it be said that the cold chain Technology fuels 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 situation is well controlled, and the possibility of contamination of seafood outer packaging is very small.
Because the spread of the new coronavirus is not only under control in many countries, but also has a tendency to continue to spread, and my country cannot directly ban the import of all frozen foods, it is particularly important to strengthen the quarantine of cold chain foods.
"The samples tested positive for nucleic acids, so people don't have to panic about it." But Liu Changyong also reminded that in the context of strict prevention of imported epidemics, this latest test result undoubtedly reminds the local customs again that they must import cold-chain food. National Gate". At the same time, we must try to choose to import food from places where the new crown epidemic situation has been controlled slightly.
Experts also reminded that in order to avoid contact with viruses 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 sterilize the seafood packaging with 75% alcohol, and wear disposable gloves when taking out the food. Frozen seafood should be washed and stored after being bought back to avoid contaminating the refrigerator and other foods. It is best to eat them all at once on the same day. In the process of processing frozen seafood, be sure to separate raw food from cooked food, and do not touch the eyes, nose or mouth with your hands. Finally, after processing frozen seafood, remember to sterilize the contacted items.
