The Wedding Buffet and the Warm Van
A catering team is delivering a cold buffet for 120 guests at a village hall. The van is not refrigerated. The food was cooked and chilled the previous evening and is packed in insulated boxes with ice packs. The journey takes 40 minutes and the buffet is due to be served 90 minutes after arrival. On arrival, the head chef uses a probe thermometer and finds the potato salad at 12°C, the sliced cooked chicken at 9°C, and the quiche at 15°C. The hall has no commercial fridge, only a domestic under-counter unit already holding drinks. The chef must decide what can be served and how to manage the remaining time before guests arrive.
1. Using the temperature readings, identify which items present a food safety risk and explain the reasoning for each.

Cooked chicken and potato salad are both high-risk foods that support bacterial growth. The chicken at 9°C is above the 8°C cold-holding limit, and the potato salad at 12°C is well above it. The quiche at 15°C is also outside safe cold holding. All three have been in the danger zone (8°C to 63°C) for an unknown but potentially significant time during transport. The safest judgement is to treat all three as potentially unsafe unless the time in the danger zone can be shown to be under the 4-hour rule and documented. The chef should not serve them on the assumption that 'they look fine' - appearance and smell are not reliable indicators of bacterial load.
2. The chef wants to use the domestic fridge for the chicken. Evaluate whether this is a sound decision and what alternatives exist.

A domestic fridge is not designed for rapid cooling or bulk storage, and it is already full of drinks. Putting warm food into it will raise the internal temperature and may push the drinks and any other food above 8°C. It also cannot cool the chicken quickly enough before service. Better options: if the total time out of refrigeration can be kept under 4 hours and documented, the food may be served within that window; otherwise it should be discarded. The chef should also check whether the ice packs are still frozen and whether the insulated boxes were pre-chilled. For future events, the lesson is to use a refrigerated van or to transport food in smaller, well-iced containers with a data logger.
3. Guests are due in 90 minutes. Outline the immediate actions the chef should take and the records that should be completed.

Immediate actions: segregate the affected items, stop any further service of them, and check whether any other items in the boxes are also out of range. If the 4-hour rule has not been exceeded and the chef can evidence the time out of temperature control, serve those items first and keep them under monitoring. If the time cannot be evidenced, discard. Record the probe readings, the time of arrival, the time of any decision, the items affected and the action taken. Notify the event organiser so they can plan alternatives. If any guests have already eaten affected food, monitor for symptoms and be ready to report under the food safety management system.
