Location: Poultry Microbiological Safety and Processing Research Unit
Project Number: 6040-32000-085-006-S
Project Type: Non-Assistance Cooperative Agreement
Start Date: Sep 1, 2023
End Date: Aug 31, 2025
Objective:
1) Determine the prevalence of multi-serovar populations in broiler parts at processing
2) Identify serovar-specific colonization in broilers and assess how this impacts serovars detected during broiler processing
Approach:
Co-operator will perform deep serotyping analyses of Salmonella sampling in parts to determine whether the increased prevalence of Salmonella in parts (it is higher in parts than in post-chill carcasses) is associated with an increase in serovar complexity (i.e., increased number of serovars per parts sample). Co-operator will perform live bird experiments in isolator units and in floor pens to assess colonization of different serovars. Carcasses will be processed in collaboration with ARS, and then Salmonella assessed.
