Which dairy categories require strict cold-chain handling?

• A. Milk, cheese, yogurt, cream, and other perishable dairy products
• B. Powdered milk and butter
• C. Frozen desserts only
• D. Cheese only

Answer: (A)

Keeping dairy products cold is essential because they are perishable and can support rapid bacterial growth if left at room temperature. Milk, yogurt, cream, cheese, and other fresh or perishable dairy items must stay in a cold chain from production through transport and storage to maintain safety and quality. Powdered milk stays dry and shelf-stable, so it doesn’t require the same strict refrigeration, and while some items like butter or frozen desserts are refrigerated or frozen, the broad category that truly requires strict cold-chain handling is perishable dairy products across the board.
