Analysis of surveillance data on outbreaks of foodborne diseases during 2000 - 2009 in Ningbo

Objective To explore the epidemiological characteristics of foodborne disease outbreaks in Ningbo and provide the scientific and reliable basis for establishment of rigorous prevention mechanisms. Methods Data on foodborne diseases reported through the public health emergency information management system in Ningbo from 2000 to 2009 were retrospectively analyzed. Results A total of 112 outbreaks of foodborne diseases were reported in Ningbo from 2000 to 2009, involving 3759 patients and 8 deaths. The largest portion of events and affected victims was caused by microbial pathogens, accounting for 69.64% and 87.15%, respectively. Salmonella typhi and paratyphi (34.72%) and Vibrio parahaemolyticus (17.27%) were the main culprits. Conclusion The incidence of foodborne disease outbreaks showed an overall declining trend after 2006. The health authority should strength the surveillance and management of foodborne diseases, actively publicize food hygiene knowledge via any possible means and encourage the citizens to get out of the poor dietary habit of consuming raw seafood such as shellfish.
