Hỏi đápWhat Is Cold Chain and How Does It Work in Logistics?

I keep hearing the term cold chain in logistics, pharmaceuticals, and food supply discussions. Can someone explain what a cold chain is and how it works? I understand it involves temperature-controlled storage and transport, but I want to know the complete process—from production to delivery.

How do companies ensure that perishable products like food, vaccines, and medicines remain safe and fresh throughout the supply chain? What equipment and technologies are commonly used, such as cold storage warehouses, refrigerated trucks, or temperature monitoring systems?

I am also curious about the challenges of maintaining a cold chain. For example, what happens if the temperature is not maintained, or if there’s a power failure or transportation delay? How do companies prevent spoilage and losses?
