| description | ObjectiveTo investigate the monitoring status and epidemiological characteristics of foodborne disease pathogens in Baoshan District， Shanghai so as to improve early detection and warning capabilities of foodborne diseases outbreaks， and to provide a scientific basis for the prevention and control of foodborne diseases.MethodsAnal swabs or fecal samples from food-borne diarrhea cases were collected from two sentinel surveillance medical institutions in Baoshan District of Shanghai during 2019 and 2021. Salmonella， diarrheagenic Escherichia coli， Shigella， Vibrio parahaemolyticus， campylobacter and norovirus were tested in anal swabs and fecal samples， and all the testing results were statistically analyzed.ResultsA total of 1 693 cases were reported， among which 1 693 anal swabs and fecal samples were collected， with a male-to-female ratio of 1.04∶1. The largest number of cases was from the age group of 45-64 years （504 cases）. The highest number of reported cases was among retirees （762 cases）. The high-incidence period of the diseases was in summer and autumn， with the highest number of cases associated with meat and meat products （566 cases）. The primary location of exposure was at home （1 260 cases）. The detection rate of pathogenic bacteria and virus was 21.32%， among which campylobacter accounted for the largest proportion （10.28%）. The peak incidence rate was from May to September. The detection rate of norovirus was 13.29%， with a higher incidence in winter and spring. The predominant serotype of Salmonella was Salmonella enteritidis （41.82%）， and the predominant local serotype of diarrheagenic Escherichia coli was EAEC （50.52%）. Campylobacter was mainly represented by jejuni （81.61%）， and the predominant type of norovirus was GⅡ （60.87%）.ConclusionCampylobacter has the highest proportion among foodborne pathogens causing foodborne diseases in Baoshan District， followed by diarrheogenic Escherichia coli. And norovirus GⅡ type is the predominant virus. Appropriate prevention and control measures should be taken based on the characteristics of each pathogen's epidemiology. |
