Methods A field epidemiological investigation and laboratory testing were carried out. Results A total of 85 people were investigated, including 55 patients（aged 24-69 years,male 26 and female 29） with an incidence rate of 64%. There were no deaths. The clinical symptoms were nausea, vomiting,abdominal pain, diarrhea and fever. Twenty-two kinds of food were sampled, and Del＇s Salmonella were detected from 3 kinds of them. Fifty-seven stool samples from kitchen staffs were collected and detected, but no pathogenic bacteria were found, and also no pathogenic bacteria were found in the samples from kitchenware. Conclusion The food-borne disease is caused by Del＇s Salmonella food poisoning. The possible reason is that the raw food and cooked food were not divided in the processing, that causes food contamination by Del＇s Salmonella. Therefore, the health education and food safety consciousness should be strengthened to effectively prevent the occurrence of similar food-borne diseases.
