Monitoring and Analysis of Coliform Bacteria in Disinfected Tableware(Drinking)in a Certain District from 2021 to 2023
Objective:To investigate the hygienic status of tableware(drinking)in various units of a district and explore the influencing factors,so as to provide reference for relevant departments to supervise food safety and make monitoring plan.Method:The coliform bacteria after disinfection of tableware(drinking)from 2021 to 2023 was monitored,and SPSS 21.0 software was used for χ2 tests.Result:From 2021 to 2023,a total of 1 098 tableware(drinking)samples were monitored,with 1 048 samples meeting disinfection standards,resulting in a pass rate of 95.45%.The differences in the pass rates of coliform bacteria in disinfected tableware(drinking)across different years were statistically significant(χ2=6.5,P＜0.05),with the pass rate initially increasing and then decreasing.The differences in the pass rates of coliform bacteria in disinfected tableware(drinking)among different types of units were also statistically significant(χ2=10.028,P＜0.05),with lower pass rates observed in employee canteens and passenger trains.Additionally,the differences in the pass rates of coliform bacteria in different types of disinfected tableware(drinking)were statistically significant(χ2=17.08,P＜0.05).Conclusion:The qualified rate of disinfection effect of tableware(drinking)was high in all units in the district,and the general condition of hygienic quality was good,but some units still had the phenomenon of incomplete disinfection of tableware(drinking),it is suggested that health supervision departments should continue to strengthen the supervision,inspection and guidance of key passenger trains,implement food safety risk control measures and guard the bottom line of railway food safety.
