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,P2=106.47,P2=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.
