Shift in the process of traditional poultry supply chain to vertical integration has developed way for poultry meat availability in India, but there is food-borne risk for human health by contamination with Salmonella spp. Therefore, the present research work was planned to study risk of Salmonella spp. in chicken meat production. Samples (n=684) were collected from farms (non-integrated and integrated) and processing units (semi-automated and automated) located around Mumbai, India and subjected to Salmonella spp. detection. Isolation of Salmonella spp. was carried out following IS 5887. The obtained isolates were subjected to identification biochemical tests, PCR testing for specific Salmonella spp. gene (invA) and serological identification. The results indicate that, over all occurrences of Salmonella spp. in farming and processing system were 6.70% and 7.53%, respectively. Higher isolation rate was observed (p<0.05) amongst various farms and processing units. Positive sample frequencies of Salmonella spp. found higher in litter (20.83%), faeces (10.41%), de-feathering (16.66%) and evisceration (25.00%). Amongst environmental samples of processing unit, knife (16.66%) and evisceration workers hands (12.50%) found to be major cross contaminating risk points. The results highlighted relevance of farm and processing level contamination for Salmonella spp. Therefore, it is essential to apply multiple interventions like, sourcing of Salmonella free chicks, litter management at farm, HACCP plan at the processing stages, use of chlorine wash and systematic cleaning or sanitation programs to avoid cross contamination.
