Objective To analyze foodborne disease outbreaks caused by Vibrio parahaemolyticus in Xinbei District of Changzhou City in 2012-2022.Methods The data of foodborne disease outbreaks caused by Vibrio parahemolyticus from January 1,2012 to December 31,2022 in Xinbei District were collected for retrospective analysis.The general circumstances of foodborne disease outbreaks was described,and the time distribution,geographical distribution and patient population distribution of foodborne disease outbreaks caused by Vibrio parahemolyticus were described.The patients'clinical symptoms,distribution of occurrence sites and occurrence causes of foodborne diseases were compared.Results During January 1,2012 to December 31,2022,a total of 19 cases of foodborne disease outbreaks were reported,involving 287 patients,among which there were 9 cases of foodborne disease outbreaks caused by Vibrio paraholyticus(accounting for 47.37%),involving 103 patients(accounting for 35.89%).All the foodborne disease outbreaks caused by Vibrio parahaemolyticus occurred from June to October,and the number of outbreaks was the highest in September(5 times,accounting for 55.56%).Foodborne disease outbreaks caused by Vibrio parahaemolyticus occurred for 3 times(accounting for 33.33%)in urban areas and for 6 times(accounting for 66.67%)in rural areas.Among the 103 patients involved in foodborne disease outbreaks caused by Vibrio paratholyticus,53 patients were male(accounting for 51.46%)and 50 patients were female(accounting for 48.54%).In age distribution,the patients of 45-64 years old accounted for the highest proportion(54 cases,accounting for 52.43%).Among the occupational distribution,the proportion of housework and unemployment was the highest(35 cases,accounting for 33.98%).Among the suspicious food distribution,the proportion of seafood and products was the highest(30 cases,accounting for 29.13%).Among the patients with foodborne diseases caused by Vibrio parahemolyticus,91 cases(88.35%)had abdominal pain,95 cases(92.23%)had diarrhea,60 cases(58.25%)had nausea,and 55 cases(53.40%)had vomiting.The proportion of abdominal pain,diarrhea,nausea and vomiting in patients with foodborne diseases caused by Vibrio parahemolyticus was significantly higher than that in patients with foodborne diseases caused by other pathogens.Among the sites of foodborne disease outbreaks caused by Vibrio parahaemolyticus,the other sites had the highest proportion(3 times,accounting for 33.33%).There was no significant difference in the site distribution of foodborne disease outbreaks caused by Vibrio parahemolyticus and other pathogens.Among the causes of foodborne disease outbreaks caused by Vibrio parahaemolyticus,the proportion of cross contamination was the highest(5 times,accounting for 55.56%).There was no significant difference in the cause distribution data of foodborne disease outbreaks caused by Vibrio parahemolyticus and other pathogens.Conclusions The proportion of foodborne disease outbreaks caused by Vibrio parahemolyticus is large in this area,and the patients were mainly middle-aged and elderly people,and the occurrence time of the incidents is concentrated in summer and autumn.Meat and aquatic products are the main suspect foods,and the patients have acute gastroenteritis as the main clinical manifestations,and the main cause of such incidents is cross infection.
