The cold chain is the supply chain that goods follow from the point of origin to the end consumer when goods need constant, proven refrigeration or freezing. Common examples of cold chain goods include produce, meat, and dairy. Not only do these goods need cold shipment and storage, but the entire journey needs to be auditable, with a proven record of temperature compliance to ensure that products meet safety and health regulations. Perishable goods must be kept at the correct temperatures during every stage of the supply chain to prevent spoilage, microbial contaminants, discoloring and bruising, and other forms of damage that affect the product’s quality and safety.
