A cold chain and a supply chain are related but distinct concepts in the field of logistics and supply chain management.
A supply chain refers to the network of entities, activities, and resources involved in the production and delivery of a product from the point of origin to the point of consumption. It includes suppliers, manufacturers, distributors, and retailers, as well as the transportation and storage of goods.
A cold chain, on the other hand, refers specifically to the temperature-controlled portion of the supply chain that is involved in the storage and transportation of perishable goods, such as food, pharmaceuticals, and biologics. The goal of a cold chain is to maintain the freshness, quality, and safety of perishable goods by keeping them within a specific temperature range throughout the entire supply chain, from the point of origin to the point of consumption.
In other words, a cold chain is a subset of a supply chain that involves the temperature-controlled storage and transportation of perishable goods. The management of a cold chain requires specialized equipment, processes, and personnel to maintain the temperature and prevent spoilage or degradation.
