Abstract:
Objective To master the changes of foodborne disease pathogen spectrum in Yichang during 2014-2020, and to understand the impact of the toilet revolution on the pathogen spectrum of foodborne diseases in Yichang. Methods The basic information on the cases of foodborne diseases in Yichang from 2014 to 2020 was collected. The fecal specimens were collected to detect pathogens, including Salmonella , Vibrio parahaemolyticus, Shigella, and diarrheogenic Escherichia coli and Norovirus. The distribution of foodborne pathogenic bacteria in food was obtained from the surveillance project report of food microorganisms and their pathogenic factors in Yichang. From 2017 to 2020, water samples from the Yangtze River were collected from May to October with frequent intestinal diseases to detect pathogenic bacteria of foodborne diseases. Results The monitoring results of foodborne diseases showed that the detection rate of norovirus increased to 6.12% year by year from 2015 to 2017, and plummeted to 0.43% in 2018, with a statistically significant difference (χ2＝60.962，P<0.05). The detection rate of bacterial pathogens decreased significantly in 2018, showing a statistically significant difference (χ2＝106.47，P<0.05). The detection rate of Salmonella was the highest. The salmonella serotypes of 2015 to 2018 and 2020 were mainly typhimurium, and the main serotypes of 2014 and 2019 were dublin and enteritidis, respectively. From 2017 to 2020, only Salmonella and Vibrio parahaemolyticus were detected in the Yangtze River water, and the detection rate was the lowest in 2018. There was significant difference in the detection rate in different years. (χ2＝44.036 , P<0.05). Conclusion The toilet revolution can reduce the detection rate of pathogens of foodborne diseases in Yichang and reduce the detection rate of Salmonella in Yangtze River water, but it has little impact on the composition of foodborne disease pathogen spectrum.
