For imported cold chain food, there will still be some new coronavirus.

Announcement of the General Administration of customs,Due to the detection of NCV nucleic acid positive in one outer packaging sample of a batch of frozen chicken legs imported from the United States, the national customs suspended the import declaration of Simmons prepared foods, Inc. (Registration Number: p1949) products from the United States poultry production enterprise for one week.

For the elimination of cold chain new coronavirus, China is also promoting some new technologies, such as nuclear technology is expected to use.

Before that, China Tongfu and Institute of Microbiology of Chinese Academy of Sciences decided to carry out the experimental scheme of inactivation of new coronavirus by using small irradiator. China Tongfu is responsible for designing and providing special irradiation equipment, and Institute of Microbiology of Chinese Academy of Sciences is responsible for the detection and evaluation of virus before and after irradiation. The experimental scheme has been approved and implemented.

The main research goal of this project is to carry out the research on the irradiation disinfection of new coronavirus, establish the irradiation disinfection process of new coronavirus, and provide the basis for the irradiation disinfection of new coronavirus in imported cold chain food. The research results are of great significance for the elimination of new coronavirus in imported cold chain food and the prevention of new coronavirus in important international competitions.

According to reports, CNNC's key technology project team has carried out the research on the simulation process of inactivation of new coronavirus in cold chain food. In the past three months, a series of irradiation inactivation experiments have been carried out using two kinds of simulation new coronavirus, and a large number of experimental data have been obtained. The simulation experiment shows that the lower radiation absorbed dose can achieve the inactivation effect, and has no impact on food safety.

At present, the research team has initially determined the dose range of irradiation inactivation of new coronavirus, but it is still a huge challenge to verify the experimental inactivation dose by using new coronavirus, and there is no similar literature report and research work in the world for reference.
