Summary

During the period of COVID-19, the health problems caused by the contamination of imported cold chain food by pathogenic microorganisms attracted widespread attention, which brought new risks and challenges to cold chain products. The traditional liquid disinfection method has obviously been unable to meet the existing disinfection and sterilization needs, and establishing a complete set of cold chain product disinfection system has become the focus of research. This paper takes the process of importing cold chain food from Tianjin's primary cold storage as an example, and proposes the closed-loop cold storage disinfection system of "Human-Cargo-Apparatus-Waste". The establishment of the disinfection system determined the working characteristics of different areas of the primary cold storage and the risk level of virus transmission through on-site analysis and simulated aerosol diffusion experiments. According to the characteristics of different working areas in the cold storage, targeted sealing measures and disinfection techniques are adopted. It can effectively ensure the complete disinfection of cold chain products and avoid the negative impact of disinfection and sterilization methods. The expected research results provide certain technical support for the development and application of safe virus elimination throughout the entire process of imported cold chain.
