What Is the Role of Cold Chain Logistics in Food Safety?

Cold chain logistics, also known as low-temperature logistics, refers to a specialized supply chain system that handles refrigerated foods to extend shelf life or fresh perishable agricultural products. Cold chain logistics is essential for maintaining food quality and reducing losses from production to retail. The business scope of cold chain logistics is not limited to dairy products, frozen foods, and other agricultural and processed foods, but also includes high-value medical supplies, vaccines, and special products such as wine and precision industrial components.

Over 90% of Hong Kong's food supply is imported, and fresh food needs to be refrigerated before retail. Through temperature monitoring equipment, cold chain logistics covers upstream and downstream processes such as production, pickup, unloading, storage, processing, picking, loading, transportation, and distribution.

Cold chain logistics is closely related to food. The key link is low-temperature storage and transportation, where the concept of seamless cold chain logistics plays an important role. From production, storage, and transportation to distribution to consumers, maintaining the freshness and quality of food is crucial to safeguarding consumer health.

Seamless cold chain logistics is vital for preventing the growth of harmful bacteria and other microorganisms that can cause foodborne illnesses. For example, perishable foods such as meat and dairy products must be kept at low or even freezing temperatures to prevent harmful bacteria from multiplying. Even a brief interruption in the cold chain can make food unsafe.
