A case study of critical points for the entry and spread of Salmonella Infantis in a broiler farm.

ABSTRACT: Salmonella Infantis is a zoonotic pathogen that frequently persists in broiler production systems, posing a risk to food safety and animal health. Understanding its entry and spread in these systems can inform control measures and reduce contamination.A longitudinal field study (2021-2022) was conducted on an eight-house broiler farm managed by three farmers to identify critical contamination points for S. Infantis. In 2021, 49 out of 536 samples (9.1%) were positive for S. Infantis, with the highest contamination rates found in anterooms (11.7%), the farm exterior (9.1%) and in the production area (7.5%). Only two out of 196 samples were positive after the implementation of cleaning and disinfection (C&D) measures. After destocking, 5.9% of samples tested positive for S. Infantis. The cri
