Abstract:

Objective To analyze the epidemiological characteristics of pathogens in foodborne disease cases in Binzhou City,and provide a basis for the prevention of foodborne diseases. Methods The distribution characteristics and serotypes of Salmonella,diarrheagenic Escherichia coli,and norovirus detected through active monitoring of foodborne diseases in Binzhou City from 2019 to 2023 were analyzed. Results A total of 1 109 samples were monitored from 2019 to 2023,from which 207 pathogens were isolated,with an overall detection rate of 18.67%(207/1 109). The detection rate was highest in 2020 at 8.52%(67/786). Among the detected pathogens,Norovirus had the highest detection rate,followed by diarrheagenic Escherichia coli,Salmonella,and Vibrio parahaemolyticus,while Shigella was not detected. Norovirus was detected in the first and fourth quarters,with norovirus genotype II being the predominant type,accounting for 80.56%. Among the diarrheagenic Escherichia coli strains,enteroaggregative Escherichia coli(EAEC) had a relatively high detection rate(38.67%). In terms of age groups,the positive detection rate of norovirus was lowest in the ≥60 age group(3.09%),and the difference was statistically significant(P<0.05). The detection rate of norovirus in males(11.40%) was significantly higher than that in females(7.32%),and the difference was statistically significant(χ2=5.070,P<0.05). There was no statistically significant difference in the detection of Salmonella,Escherichia coli,and norovirus among different types of suspicious food samples(χ2=6.941,5.404,5.581,all P>0.05). There was no statistically significant difference in the detection of pathogens among food samples processed by different methods(P>0.05). Conclusion From 2019 to 2023,foodborne diseases in Binzhou City are mainly caused by norovirus genotype II and EAEC,with a high incidence in autumn and winter,and children and young adults are more susceptible. It is necessary to strengthen the full-chain supervision of food,standardize catering operations,focus on collective venues,and carry out health education.
