A cold room is a refrigerated room for storing food at chill temperatures, also called a cold store. Found in restaurants, catering operations, and food factories, it holds perishable stock, from dairy and meat to prepared dishes, at 0°C to 5°C in bulk quantities that would overwhelm domestic refrigerators. Good design includes even air circulation, easy-clean surfaces, calibrated temperature monitoring with alarms, and organised racking that separates raw and ready-to-eat foods. Staff discipline matters: doors left open, warm stock loaded carelessly, and poor rotation all undermine the room’s purpose. It is the heart of a professional kitchen’s food safety system.
