What is cold chain?

Cold chain refers to a temperature-controlled supply chain used to store, transport, and handle products that are sensitive to temperature fluctuations, such as vaccines, pharmaceuticals, and certain foods. Maintaining the correct temperature throughout the entire process is crucial to preserving the quality, safety, and efficacy of these products. Cold chain management involves specialized equipment like refrigerated trucks, cold storage warehouses, and monitoring systems to ensure products remain within required temperature ranges.
