Objective: In order to solve the problem of food hygiene in cooked food knives, plates and tableware disinfection of grassroots units. Methods: According to the principle of UV disinfection, a UV disinfection cabinet was developed. E. coli (80 99) was used as an indicator bacteria to observe the disinfection effect of disinfection cabinet on different samples after inoculation. Meanwhile, the application effect was monitored. Results: After being inoculated, the chopping knives and chopping boards were put into the sterilizing box for 5 min, and the protective effect of low concentration (10%) serum for 5 ~ 10 min could achieve the killing effect of over 99.8%. The temperature and humidity No effect; through field use and monitoring, bactericidal effect and experimental results are basically the same. Conclusion: The UV disinfection disinfection disinfection effect is reliable, short duration of action, is the grassroots company catering health protection in a better equipment
