The cold chain describes the unbroken sequence of temperature-controlled steps – production, storage, transport, and final delivery – through which perishable or temperature-sensitive goods must pass without deviation from their specified range. Any breach at a handover point, loading dock, or during transit can compromise food safety, drug efficacy, or the viability of biological samples. Infrastructure components include insulated packaging, refrigerated vehicles, temperature-controlled warehouses, and continuous monitoring systems with data loggers and GPS. Pharmaceutical cold chains are governed by Good Distribution Practice (GDP) guidelines; food logistics must comply with applicable food safety regulations. The cold chain is a system-level concept spanning multiple parties, contracts, and responsibilities – not a single asset or mode of transport.
