Today, the prevention and control of internal epidemics have become regular. While the epidemic situation abroad remains dire, the country strictly controls foreigners entering the country, effectively halting the spread of the epidemic. However, the cunning new corona virus has found other forms of import, namely cold chain transport, which spreads the epidemic through imported cold chain food. Recently, imported cold chain food and its outer packaging frequently show positive nucleic acid tests, and a large part of the new local cases in many places in China are also related to imported cold chains.
Some time ago, the outbreaks in Beijing, Dalian and Qingdao were caused by cold chain seafood, and the origin of the first Wuhan epidemic was the South China seafood market in Wuhan. This does not make the people doubt if it was also an imported cold chain. Product caused. This has also raised public concern about the safety of cold chain foods. Can you buy food from the cold chain? In addition to strict national control, what measures against the epidemic can we take?
Can you buy imported products from the cold chain?
According to the research, under normal temperature conditions, at 21-23 ° C, the new coronavirus cannot survive more than 4 hours on copper surfaces, cannot survive more than 24 hours on cardboard surfaces, and cannot survive more than 3 hours. days on stainless steel and plastic surfaces. In low temperature conditions of 4 ° C and -20 ° C, the new coronavirus remains infectious after 3 weeks. In the process of packaging, transporting and retailing of cold chain products, the temperature is generally controlled to around -18 ° C, which means that the cold chain will provide a good pathway for the spread of the new coronavirus. .
So, can you buy imported products from the cold chain? In fact, everyone should know that a positive coronavirus nucleic acid does not necessarily mean that it is a live virus that is infectious. Live viruses, dead viruses, and virus fragments can be detected. The nucleic acid is positive. Regarding the detection of the new corona virus in imported cold chain products, the competent Chinese authorities have adopted a series of effective control and control measures. On November 9, the Joint Prevention and Control Mechanism of the State Council for imported food from the cold chain issued the “Prevention of imported food from the cold chain”. Comprehensive disinfection work program.
Therefore, under the country’s strong prevention and control measures, the vast majority of food that eventually reaches consumers is very safe food. Therefore, imported cold chain food can still be purchased with confidence, without undue panic.
What should we do?
Faced with the spread of the new coronavirus through the cold chain, the first anti-epidemic method that we think of is not to touch food directly with your hands, not to touch your mouth, eyes and nose with hands that come into contact with fresh food , and use soap, hand sanitizer or soap after purchase. Wash your hands well under running water. However, we have overlooked a problem, that is, the purchased products may not be able to be eaten all at once, if they cannot be eaten, they will face storage conditions and the place to store the food is the refrigerator .
As we mentioned earlier, in low temperature conditions of 4 ° C and -20 ° C, the new coronavirus is still infectious after 3 weeks. And this temperature range corresponds exactly to the refrigeration temperature and the freezing temperature of the refrigerator. In other words, the refrigerator is also a hotbed for the spread of the virus. So how can we prevent the refrigerator from becoming an accessory to the spread of the virus?
Clean and disinfect the refrigerator regularly
The first is to clean and disinfect the refrigerator regularly. The common method of cleaning your refrigerator is to use hot water and soapy water or baking soda to clean and dry. These methods can effectively clean the refrigerator, remove the peculiar smell, and also have a certain sterilization and disinfection effect. Of course, in order to have a better disinfection effect, it is recommended to clean and disinfect with 1000 ~ 2000mg / L quaternary ammonium salt disinfectant for 30 minutes, clean with clean water, or clean with 75% alcohol twice. It should be noted that chlorine-containing disinfectant is harmful to the human body and cannot be used to clean the inside of the refrigerator.
Also, the refrigerator partitions and door sealing strips need to be cleaned too, where bacteria can easily breed. It is also necessary to pay attention to the shutdown when cleaning the refrigerator to avoid unnecessary risks.
Store cold chain foods properly
It is also necessary to strictly classify the ingredients in the refrigerator. Cold chain products to be purchased should be stored separately from other ingredients, especially some cooked foods, to avoid cross infection, it is better to use separate sealable fresh food preservation boxes to sort and store the ingredients. You can also divide the purchased meat into small pieces and pack them in fresh preservation bags according to the amount consumed at one time.
If purchased cold chain foods are placed in the refrigerator for a short period of time, since the ingredients in the refrigerator will thaw slowly, the water that comes out will contaminate other ingredients. Therefore, it is better to place them in the bottom of the refrigerator and use containers to prevent the leakage of sewage.
Write at the end
Although the new corona virus can be transmitted through the cold chain, under the country’s strong epidemic prevention measures, most of the products finally sold on the market are safe and our consumers can still buy with confidence, without Panic. But at the same time, we should not take it lightly, we still have to take all kinds of epidemic prevention measures, especially refrigerators, which store food, in this special period we must pay special attention to cleaning and correct use.
