2.3 Cooling & Thawing Controls

Cooling and thawing controls

Cooked food that will be stored must move through the danger zone quickly. The current Qatar MOPH Food Safety Code requires cooling to 5°C or colder within 2 hours. Do not substitute a six-hour two-stage rule from another jurisdiction. Start cooling promptly and use a method capable of removing heat from the centre of the food, not just its surface.

Practical controls include dividing a large batch into smaller or shallower food-grade containers, using a blast chiller, placing suitable containers in an ice-water bath and stirring with clean equipment, or using another validated facility method. Arrange containers so cold air can circulate. Avoid placing a deep, steaming stockpot into an overloaded refrigerator and assuming the unit will cool the centre in time. Measure the food with a clean and disinfected probe and record the result when required. If the limit is missed, follow the documented corrective-action and discard decision; relabelling the batch does not restore safety.

Thaw frozen food under controlled conditions that keep the product safe and prevent raw drips from contaminating ready-to-eat food. Controlled refrigeration is the usual planning method. Other approved methods may be used when the facility procedure controls time, temperature and immediate cooking. Do not leave high-risk food thawing unattended at room temperature. Keep it covered, use a container that contains drips and place it below ready-to-eat items in cold storage.

Plan backwards from service time. Large products need enough refrigeration time to thaw safely; a last-minute shortcut often creates both a warm surface and a frozen centre. In exam scenarios, prefer a monitored method, hygienic separation and documented corrective action over room-temperature thawing or an unsupported foreign time rule.
