Analysis of monitoring results of foodborne pathogens in Baoshan Districtï¼ Shanghaiï¼ 2019â2021
Journal Title: Shanghai Journal of Preventive Medicine - Year 2023, Vol 35, Issue 10
Abstract
ObjectiveTo investigate the monitoring status and epidemiological characteristics of foodborne disease pathogens in Baoshan Districtï¼ Shanghai so as to improve early detection and warning capabilities of foodborne diseases outbreaksï¼ 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. Salmonellaï¼ diarrheagenic Escherichia coliï¼ Shigellaï¼ Vibrio parahaemolyticusï¼ campylobacter and norovirus were tested in anal swabs and fecal samplesï¼ and all the testing results were statistically analyzed.ResultsA total of 1 693 cases were reportedï¼ among which 1 693 anal swabs and fecal samples were collectedï¼ with a male-to-female ratio of 1.04â¶1. The largest number of cases was from the age group of 45-64 years ï¼504 casesï¼. The highest number of reported cases was among retirees ï¼762 casesï¼. The high-incidence period of the diseases was in summer and autumnï¼ with the highest number of cases associated with meat and meat products ï¼566 casesï¼. The primary location of exposure was at home ï¼1 260 casesï¼. The detection rate of pathogenic bacteria and virus was 21.32%ï¼ among which campylobacter accounted for the largest proportion ï¼10.28%ï¼. The peak incidence rate was from May to September. The detection rate of norovirus was 13.29%ï¼ with a higher incidence in winter and spring. The predominant serotype of Salmonella was Salmonella enteritidis ï¼41.82%ï¼ï¼ and the predominant local serotype of diarrheagenic Escherichia coli was EAEC ï¼50.52%ï¼. Campylobacter was mainly represented by jejuni ï¼81.61%ï¼ï¼ and the predominant type of norovirus was Gâ ¡ ï¼60.87%ï¼.ConclusionCampylobacter has the highest proportion among foodborne pathogens causing foodborne diseases in Baoshan Districtï¼ followed by diarrheogenic Escherichia coli. And norovirus Gâ ¡ type is the predominant virus. Appropriate prevention and control measures should be taken based on the characteristics of each pathogen's epidemiology.
