Abstract: Objective To analyze the epidemiological and pathogenic features of foodborne disease cases in Baotou City from 2017 to 2021,so as to provide reference basis for the prevention and control of foodborne diseases. Methods The monitoring data of foodborne disease in Baotou City from 2017 to 2021 were collected from the foodborne disease monitoring and reporting system,the pathogen testing was performed on the collected stool/anal swab samples,and the data were analyzed. Results A total of 8 971 foodborne disease cases were included and 1 207 stool/anal swab samples were collected,including 4 221 males and 4 750 females.The largest number of cases was in the age group of 18-<35 years old（2 246 cases）,the largest number of cases was in students in terms of occupation（1 332 cases）,the peak incidence period was July-September,the cases caused by the meat and meat products among exposed foods were the most（1 636 cases）,the packaging method was mainly bulk mode（3 603 cases）,and the exposed places were mainly at home（6 202 cases）.The detection rate of pathogens was 25.35%,among which the detection rate of pathogenic bacteria was 15.07%,mainly diarrheogenic Escherechia coli（13.50%）,and the detection rate of norovirus was 11.27%. There were statistically significant differences in pathogen detection rates among age,occupation,and seasonal groups（all P<0.01）. Conclusion The main pathogens of foodborne diseases in Baotou City from 2017 to 2021 are diarrheogenic Escherechia coli and norovirus,the incidence of foodborne disease is relatively higher in summer and autumn,and it is necessary to strengthen publicity and training to minimize the occurrence of foodborne diseases and ensure the health of the public.
