    Abstract:

    To analyze the epidemiological characteristics of foodborne disease in Jilin Province in 2013-2015, and to propose targeted measures and recommendations for the prevention and control of foodborne disease outbreaks.Methods Descriptive analysis and statistical tests were used to analyze data from foodborne disease surveillance and report system in Jilin Province in 2013-2015. Results There were 12 049 cases of foodborne diseases in Jilin Province in 2013-2015. Among all specimens for pathogen detection collected from 11 497 cases, 807 patients were detected positive for pathogenic microorganisms. The overall foodborne pathogen detection rate was 7.02%; the detection rate was 15.63% (389/2 489) for Norovirus, 2.54% (283/11 141) for Salmonella, 1.32% (147/11 167) for Diarrheagenic E.coli, 0.08% (9/11 153) for Shigella, 0.06% (6/9410) for Vibrio parahaemolyticus, and 0.00% (0/201) for Yersinia nterocolitica. Norovirus, Salmonella and Diarrheagenic E.coli were more common foodborne than Shigella, Vibrio parahaemolyticus and Yersinia enterocolitica in Jilin Province (P<0.05). The detection rate of Norovirus in the first quarter (31.00%) was the highest in the year; the detection rate of Salmonella in the second and third quarters (3.78%, 3.12%) were higher than the first and fourth quarters; the detection rate of Diarrheagenic E.coli in the second and third quarters (1.32%, 1.69%) were also higher than the first and fourth quarters; the detection rates of Shigella and Vibrio parahaemolyticus in the third quarter (0.14 %, 0.15%) were the highest. Norobvirus detection rates were higher in over 85 year-old group and under 5 year-old group (20.00%, 18.90%), the detection rates of Salmonella and Diarrheagenic E.coli were the highest in under 5 year-old group (3.38%, 1.75 %). The detection rate of foodborne pathogens in 2015 was higher than those in 2013 and 2014 (P<0.05), and the detection rate was lower in the fourth quarter than the other three quarters (P<0.05).The detection rate had no significant difference between genders (P>0.05). Those under 5 years old, commercial service staff, urban residents had the highest detection rate of foodborne pathogens (P<0.05). Conclusion Since 2013, pathogen detection rate of foodborne disease in Jilin Province has been increasing year by year. The detection rates in the first, second and third quarters were higher than the fourth quarter. Norovirus, Salmonella and Diarrheagenic E.coli wer e main pathogens, and those under 5 years old and commercial service staff were vulnerable group.
