Shifts in surface microbiota after cleaning and disinfection in broiler processing plants: incomplete biofilm eradication revealed by robotic high-throughput screening.

ABSTRACT: Broiler processing environments are a source of spoilage bacteria and potential pathogens. The aim of this study was to investigate the impact of cleaning and disinfection (C&D) on bacterial load and diversity in two broiler processing plants and to determine the efficacy of industry-standard disinfectants (DIs). C&D significantly reduced average bacterial loads on surfaces from 3.7 to 1.8 log CFU/cm² in Plant A and from 7.0 to 3.8 log CFU/cm² in Plant B (P < 0.001). Metataxonomics revealed that Acinetobacter and an unknown Enterobacteriaceae genus dominated before C&D in Plants A and B, respectively, while Pseudomonas was predominant after C&D in both plants. Bacterial diversity only declined significantly after C&D in Plant B. Bacterial loads al
