The average detection rate was 3. 25% in Huangpu District, which was slightly higher than the average level of Shanghai （3.13% ）. Most cases occurred between May and October. The incidence rate in male was 1.53 times higher than that in female. People between 20 and 39 were more likely to get infected. Salmonella Enteritis （ 31.83% ） and Salmonella Typhimurium（ 15.57% ） were the dominant serotypes.
