To establish a proactive, multi-stage preventive framework that identifies and mitigates Listeria monocytogenes contamination risks before positive pathogen samples occur in food processing plants.
Synthesized findings from scoping reviews, simulation studies, whole genome sequencing research, and root cause analysis case studies across ready-to-eat food processing environments.
Assessed operational implementation barriers, including capital costs, technical capacity constraints, and organizational culture.
Identified that conventional reactive monitoring permits persistent Listeria harborage and recurrent contamination due to resilient biofilm formation in equipment and drains.
Formulated a five-pillar preventive strategy incorporating risk-based zone mapping, harborage-targeted sanitation, molecular surveillance, predictive risk analytics, and closed-loop corrective actions.
