First of all, it can be clearly said that the cold chain food traceability system will not only have a negative impact on consumption, but also increase people's desire to shop. In this special period of epidemic situation, food safety is the top priority, and the cold chain food traceability system will make the food safety rise linearly. Under such conditions, consumers can naturally buy all kinds of cold chain foods with more confidence. Strictly controlling the import process of cold-chain food is obviously more beneficial than harmful to consumers. The only impact of this traceability system is that it will increase the steps for merchants to import food. For example, in the past, merchants only needed to pass a simple safety inspection when importing cold-chain food, but after the traceability system went online, they not only needed to upload the source of food, but also needed to show the COVID-19 quarantine certificate. After a series of traceability processes, cold-chain food could enter the country and be sold to people.

The reason why the cold chain food traceability system was launched is that some imported aquatic products detected Covid-19 during the period of COVID-19, but this traceability system launched in Henan Province can effectively solve this problem. All aquatic products imported from high-risk areas are not allowed to enter the China market, which directly cuts off the spread across the sea in Covid-19. China managed to control the COVID-19 epidemic with great difficulty, and naturally, the efforts of many front-line doctors should not be wasted because of imported food.

From another point of view, after the cold chain food traceability system goes online, consumers can check the source of food by scanning the code, and they can see all kinds of information of cold chain food at a glance on their mobile phones, even the quarantine certificate can be easily queried, and under such circumstances, consumers' sense of security will soar. The earlier aquatic product COVID-19 incident made consumers panic about some cold-chain foods, and the panic of consumers will naturally dissipate after the traceability system goes online.

To sum up, I think the cold chain traceability system launched in Henan Province can not only improve the food safety, but also effectively enhance consumers' shopping desire. I have to say that this traceability system is worth popularizing in the whole country.
