Food Service Systems, Food Safety, and Institutional Management
What this domain tests
This domain tests safe, compliant food production in hospitals and institutions, including HACCP, temperature control, therapeutic diet accuracy, and resource management.
Core rules
- HACCP has seven principles: hazard analysis, determine CCPs, set critical limits, monitor, establish corrective actions, verify, and keep records.
- The temperature danger zone is 5–60°C. Hot holding is at or above 60°C; cold holding at or below 5°C. Cook poultry to 74°C. Cooling should move food rapidly through the danger zone.
- A CCP is a step where control prevents, eliminates, or reduces a hazard to an acceptable level. Critical limits must be measurable, such as temperature and time.
- Cleaning removes soil; sanitizing reduces microorganisms. Both are required for food-contact surfaces.
- Therapeutic diets require verification at tray assembly. Use standardized recipes, color-coded trays, and double checks for allergens and texture-modified diets.
- FIFO and date labeling reduce spoilage. IDDSI levels standardize texture-modified foods and thickened liquids.
Worked example
Cooked rice is held on a tray line at 48°C for three hours. Hot holding is a CCP; the critical limit is at least 60°C. Monitoring shows a deviation. Corrective action: discard the rice or, if within an approved recovery procedure, reheat to 74°C and document. Then investigate the holding unit, recalibrate the thermometer, retrain staff, and verify records. Do not simply turn up the unit without documenting the batch.
Traps
Confusing cleaning with sanitizing; treating HACCP as the same as ISO 9001; using a probe thermometer without calibration; assuming a low oven setting is a safe hold; failing to record corrective actions; ignoring allergen cross-contact on the tray line.
