To evaluate the contamination and hazards of Salmonella in broiler industry and provide basic data for the risk assessment and control from farm to table.Methods Different samples were collected from broiler industry of incubation, cultivation, slaughter, sales and distribution process, and all samples were tested according to GB 4789.4-2010. Results 298 strains of Salmonella were isolated from 1 267 samples, and the total detection rate was 23.5%.The detection rates of incubation, cultivation, slaughter, sales and distribution process were 4.6%, 8.4%, 32.8% and 31.3%, respectively. The main serotypes were Salmonella Indianas and Salmonella enteritidis. Conclusion Salmonella was detected in the whole chain of broiler industry. There was no statistic significant in the detection rate of different seasons. Cross-contamination may be existed in slaughter process and this process is important to control Salmonella contamination for chicken and chicken products.
