Surveillance results of foodborne diseases in Jinan in 2013 - 2021 / 公共卫生与预防医学

ABSTRACT

Objective To understand the epidemiological and etiological characteristics of foodborne diseases in Jinan City, and to provide targeted measures for the prevention and control of foodborne diseases. Methods Data were collected from the reporting system of two sentinel hospitals for active surveillance of foodborne diseases in Jinan City from 2013 to 2021, and pathogens were detected in stool/anal swab samples of the cases. Constituent ratio was used for enumeration data, and χ2 test was used for comparison of detection rates. Results A total of 5,417 cases of foodborne diseases were reported in the two sentinel hospitals in Jinan from 2013 to 2021, and most of them were children aged 0-5 years (48.57%). The high incidence period of foodborne diseases was from May to August (53.72%). The main clinical symptoms were digestive system symptoms. Meat and meat products accounted for the largest number of suspected exposed foods (13.89%), and home-made food was the main exposure source (45.83%). The total detection rate of pathogens was 38.40%, mainly Escherichia coli (24.22%), and the detection rate of norovirus was 17.76%. There was a significant difference in the detection rate of pathogenic bacteria before and after the establishment of Healthy City (χ2=107.22, P <0.001). Conclusion The high-risk population for foodborne diseases is children aged 0 to 5 years old. Summer and fall are the high incidence seasons, with E. coli and norovirus as predominant pathogens. It is necessary to continue to strengthen the monitoring of foodborne diseases in high-risk seasons and infants, improve the food safety awareness of high-risk groups, increase monitoring sentinel hospitals, and expand the coverage. In addition, relevant departments should take corresponding prevention and control measures to reduce the occurrence of foodborne diseases.
