Cold Chain

Cold chain refers to the temperature-controlled supply chain required to transport and store perishable products like food, pharmaceuticals, and chemicals.

Examples: Shipping fresh seafood from Alaska to Japan, distributing COVID-19 vaccines that must stay at -70°C, or moving dairy products across the U.S. in refrigerated trailers.

Advantages: Preserves product quality, prevents spoilage, and ensures compliance with health and safety regulations.

Challenges: High operating costs, strict regulatory requirements, and increased risk if refrigeration equipment fails.

Real-world example: Pfizer’s COVID-19 vaccine rollout required specialized freezers and cold chain logistics providers worldwide.

Explain like I’m five: It’s like keeping your ice cream in a cooler so it doesn’t melt before you get home.

FAQ: What technology is used in cold chain? Refrigerated trucks (reefers), insulated containers, and temperature-monitoring sensors.

Bottom line: Cold chain logistics are vital for perishable and sensitive goods, but they require precision and investment to succeed.
