A woman in Shanghai specially tested the antigen of crayfish before cooking it. After learning that the test result was negative, she was relieved to cook crayfish. Contact with imported food during the epidemic requires attention to food safety. Personally, I think two things need to be done to ensure food safety. First, buy ingredients from regular supermarkets and try to avoid frozen products; Second, you can sterilize food without buying imported food.

First, there are formal channels for regular supermarkets to buy food, but there are no formal channels for purchasing goods from food supermarkets with unknown sources. For foods that may be involved in the epidemic, nucleic acid testing will be done. Big supermarkets pay for epidemic prevention work, so we can buy supermarket goods with confidence. Compared with epidemic prevention, the epidemic situation in supermarkets has a greater impact.

Therefore, in our daily life, we go to the regular supermarket near the living circle to buy food. Don't buy food from unknown sources. This can also reduce the chance of being infected by the virus and do your best to ensure your health. When we go shopping in the supermarket, we should try not to touch other foods except those we need to buy, which is also a powerful protection for ourselves in the COVID-19 epidemic.

Second, import food and fruits and try not to buy them. The situation of domestic epidemic prevention and control is very good. Compared with domestic epidemic prevention and control, foreign epidemic is rampant. If we want to avoid contact with COVID-19's food, we should buy as little imported food and fruit as possible. In the process of epidemic spread, many of them were caused by imported food from abroad.

Without buying food shipped from abroad, you can cut off the food chain shipped from abroad and spread the virus. Not only do you have to do this well, but also your relatives around you should be treated equally, so as to resist possible viruses.

The practice of women doing antigen testing for crayfish has sparked heated discussion among netizens. Some people think that the epidemic prevention and control is very good; Some people think that this is a waste of antigen detection reagents. How to treat this behavior?
