Objective To explore the epidemiological characteristics of foodborne diseases in a specific pathogen in Jiaxing City. Methods A total of 2 711 cases of food-borne diseases that met certain pathogens were selected in 2014. Basic information was collected and stool specimens were collected for the detection of specific pathogens. Results A total of 265 positive strains were detected in 2 711 stool specimens, with a crude detection rate of 9.77%. The detection rates of Salmonella, Vibrio parahaemolyticus, diarrheal Escherichia coli and Norovirus were 1.70% , 2.62%, 2.07% and 10.66%, respectively. The detection rate in summer was higher. 604 cases provide suspicious food exposure history, mainly aquatic products, accounting for 16.72%. Conclusions Foodborne pathogens are mainly Norovirus and Vibrio parahaemolyticus. Suspicious exposure to foodstuffs is aquatic products. Health education should be strengthened to improve people’s food safety awareness.
