From Food Safety to Operational Readiness: A Risk-Based Framework for Military Ration Systems

Abstract

Context: Operational rations constitute a health-support system rather than a simple inventory item. They must remain safe, nutritionally appropriate, acceptable, and usable across diverse missions and environments. A ration may meet its written specification yet fail operationally if it is not consumed, is degraded during storage, cannot be prepared under field conditions, or cannot be rapidly traced during a safety event. This expert review presents a risk-based framework that links ration governance to measurable readiness outcomes. Evidence Acquisition: PubMed/MEDLINE was searched from inception through July 31, 2026, supplemented by targeted searches of official military, food-safety, and standards sources. Eligible evidence addressed energy balance and intake, acceptability, nutrient adequacy, enteric disease, packaging, shelf life, hazard control, traceability, and surveillance. A reproducible PubMed search logic is reported in the full text. Twenty-eight sources were retained for narrative synthesis; because the original expert-review search was iterative, a formal PRISMA-style deduplicated screening count was not maintained prospectively. Results: Evidence supports an implementation gap between food issued and food consumed. Field studies show marked energy deficits despite ration availability, and factors such as preparation time, food temperature, task tempo, menu fatigue, and equipment constraints influence intake. Foodborne outbreaks can cause clustered illness and duty loss, and thermal or packaging failures can degrade quality before obvious spoilage. The proposed five-domain Ration-to-Readiness (R2R) framework comprises mission profiling, product and supplier assurance, logistics integrity, consumption assurance, and health-readiness feedback, with leading indicators, example accountable functions, and illustrative, locally calibrated triggers. Conclusions: Military ration systems should be evaluated based on verified consumption, safety, and readiness effects rather than procurement compliance alone. The R2R framework is an author-developed, standards- and evidence-informed policy model; however, its proposed benefits and action thresholds require prospective validation across forces, climates, and mission profiles.
