The Buffet at 13:15: No Logs, a Dead Chafing Fuel and Four Temperatures
13:15 in a hotel ballroom. The lunch buffet opened at 11:30 for 200 guests and runs until 14:30. A spot check with a calibrated probe gives: chicken skewers on the steam table at 51 °C; mashed potatoes at 64 °C; shrimp cocktails on the cold line at 9 °C; and a large bowl of dressed leafy salad at 13 °C. The steam table water has almost boiled dry and one chafing fuel has gone out under the chicken. Nobody has logged placement times, and there is no record of when the chicken went out or how long it sat below 60 °C, although the captain believes it was "around 11:30." The captain wants to top up the chicken pan with a fresh batch from the oven, add ice under the shrimp, and keep the line open because the client paid for two full hours of service.
1. Make a keep / reheat / chill / discard decision for each of the four items, and explain how the missing log changes the answer.

The governing limits: hot holding ≥60 °C, cold holding ≤4 °C. Where food has left temperature control, the common rule is that if it has been out of range for less than 2 hours it may be corrected (reheated to 74 °C for hot food, rapidly chilled to 4 °C for cold food); beyond that it is discarded. The alternative is time as a public health control: a maximum of 4 hours with the start time labelled, the food starting at ≤4 °C or ≥60 °C, and discard at the end.
- Chicken skewers, 51 °C: the failure is in the missing record, not the thermometer. 51 °C is not hot holding. If a label or log proved the skewers were placed at 11:30, they have been under 60 °C for at most 1 h 45 min, and you could reheat to 74 °C, return them to a working steam table and start a log. With no log and a fuel that has gone out, the time below 60 °C is unverified - discard is the defensible call.
- Mashed potatoes, 64 °C: compliant. Keep, and fix the water level and fuel to keep them there.
- Shrimp cocktails, 9 °C: cold holding violation. Under 2 hours, nest the trays in ice with drainage and bring back to ≤4 °C, then monitor. Any uncertainty about time means discard.
- Dressed leafy salad, 13 °C: cut greens plus dressing is TCS. Same 2-hour logic; in practice, dressed salad will not re-chill usefully on a warm buffet, so discard and replace from refrigerated stock.
When the record is missing, the inspector cannot verify the short-duration exception, so the burden of proof fails and the food goes.
2. Explain why topping up the chicken pan is unacceptable even though the added chicken is freshly cooked.
Read the worked answer
Topping up blends new food into old food and destroys the only information you have: the age of the product in the pan.
- The fresh skewers inherit the temperature history and contamination of the old ones, including anything the guests' serving tongs introduced.
- The 4-hour clock, if you were relying on time as a control, is reset for the whole pan, so the old food effectively becomes immortal - every top-up restarts the timer.
- The pan never returns to a verified ≥60 °C as a whole, because adding hot food to a 51 °C mass gives a mixed, unverified temperature.
- An inspector reading a top-up as routine practice will treat the entire holding operation as uncontrolled.
Correct practice: pull the old pan, discard its contents, wash and sanitize the pan, and refill with a freshly cooked batch in a clean pan that carries its own label with the time it was placed. The same rule applies to the salad bowl and the shrimp trays - replace, never replenish.
3. Set out what must be in place for the remaining 75 minutes of service, and what records the banquet team must complete.

Before the line reopens:
- Restore the steam table - refill water, replace dead fuel, or move to a working hot-holding unit - and verify with a probe that it can hold ≥60 °C.
- Discard and replace all non-compliant items; reheat anything being recovered to 74 °C and verify with a probe.
- Set cold items in deep ice with drainage, not a shallow garnish of ice; keep the ice level above the food line.
- Reduce pan sizes so food turns over faster, and hold back backup product in the cooler rather than putting everything out at once.
- Assign one named monitor per service with a calibrated probe, checking each item every 30 minutes and writing the number down.
- Label any item held under time as a public health control with its start time and the discard time, and take that decision before the food goes out, not after.
Records to complete: temperature log with times and initials; corrective action log listing each discarded item with quantity and reason; the probe calibration check; and a note of the equipment fault. Brief the captain that the buffet closes at 14:30 and everything left out is discarded at that point - the client's contract does not override the limit.
