Abstract
Mass food production improves food availability, affordability, standardization, and distribution efficiency, but it can also magnify the consequences of a localized food-safety failure. This structured qualitative integrative review examines how biological hazards, chemical contaminants, allergens and emerging contaminants enter, persist and spread through large-scale food-production systems, and how these hazards can develop into highconsequence public-health events. The synthesis draws on 60 peer-reviewed publications from 2020 through September 2026, supplemented by Codex and ISO framework documents for benchmarking established food-safety approaches. The evidence indicates that scale is best understood as a consequence multiplier rather than an independent hazard: large batches, interconnected equipment, persistent environmental reservoirs, crosscontamination, centralized distribution and delayed detection can expand both the number and geographic reach of exposures. Effective mitigation therefore requires a defence-indepth architecture that integrates supplier assurance, hygienic design, validated process controls, sanitation, allergen management, environmental monitoring, rapid diagnostics, digital traceability, recall preparedness and organizational learning. Emerging technologies, including biosensors, whole-genome sequencing, high-pressure processing, cold plasma, Internet-of-Things monitoring and data-driven analytics, can strengthen these layers, but their evidential maturity and industrial readiness vary and each application requires matrixspecific validation and governance. The review proposes an integrated risk-amplification framework that links hazard introduction, persistence, transfer, batch amplification, distribution, detection delay, exposure and consequence containment while explicitly positioning the framework as complementary to HACCP and food-safety management systems.
