Abstract:
Objective To study the infection, serotype distribution and etiological food sources of Salmonella in active surveillance of foodborne diseases in Jiangsu Province from 2015 to 2020, so as to understand the infection of Salmonella in foodborne diseases in Jiangsu Province. Methods A total of 68656 cases were collected from sentinel hospitals in 13 districts and cities in Jiangsu Province, and 1920 strains of Salmonella were detected and isolated. The serological typing, seasonal variation trend, patient gender, age and traceability of related etiological food were studied. The results were statistically analyzed. Results The 1920 Salmonella strains isolated from sentinel hospitals were widely distributed in 124 serotypes, and the serotypes showed polymorphic distribution, with Salmonella typhimurium (accounting for 25.10%%) and Salmonella enteritidis (accounting for 23.49%%) as the dominant strains. The season of onset was mainly summer. The onset age was mainly infants under 3 years old. The proportion of male cases was higher. Milk and dairy products (accounting for 11.98% with a detection rate of 3.93%) were the main type of suspected pathogenic foods. Conclusion Relevant departments should strengthen the market supervision of meat and dairy foods, continue to actively monitor Salmonella diseases, improve the ability of early identification, early warning and control of food safety hazards, and reduce the occurrence of foodborne diseases.
