On August 10, 2013, several members of different groups started to show gastrointestinal symptoms after consuming dinner food at X Ranch restaurant and were sent to several hospitals or clinics for medical care. We conducted a case-control investigation on one marathon association members. The results from 59 questionnaire data showed 40 persons fitted to the case definition with an attack rate of 67.8%. The figure of case onset date distribution indicates this cluster event is a food poisoning outbreak. The dish of the chopped garlic chicken shows statistically responsible for this food poisoning outbreak (P<0.05). According to the laboratory results, the characteristics of patients’ symptoms and incubation period, the etiologic pathogen of this outbreak can be determined to be Salmonella, group O7.
