Cool Room Failure Before a Wedding Function
A catering company is preparing a 120-guest wedding lunch for Saturday. On Friday at 8:00 pm, the head chef discovers the main cool room is reading 14 degrees Celsius. The cool room holds 40 kg of raw chicken thighs, 15 kg of cooked prawns, 20 L of cream-based soup, 10 kg of cut fruit, and 30 kg of raw beef. The thermometer log shows the cool room was last checked at 3:00 pm and read 4 degrees Celsius. No one knows when the failure began. A second small cool room is working at 3 degrees Celsius but has only about one-third of the needed space. The wedding is at 12:00 pm Saturday and the client has paid a 50 percent deposit.
1. Apply the temperature danger zone and the two-hour/four-hour principle to decide what can be kept, what must be discarded, and what evidence you need before making that call.

The temperature danger zone is 5–60 degrees Celsius. The cool room was last verified at 4 degrees Celsius at 3:00 pm and is now 14 degrees Celsius at 8:00 pm, so the food has been above 5 degrees Celsius for an unknown period of up to five hours. That uncertainty is the central problem.
Use the two-hour/four-hour principle as a guide:
- Under 2 hours in the zone: food may be cooled back to 5 degrees Celsius or below and used.
- 2–4 hours: food may be used but must be consumed immediately and not returned to storage for later use.
- Over 4 hours: food must be thrown out.
Because the exact time is unknown, the chef must assume the worst credible case unless evidence proves otherwise. Practical decisions:
- Raw chicken and raw beef: if they are still cold to touch and there is any chance they were under 5 degrees Celsius for most of the period, they may be moved to the working cool room and cooked thoroughly to 75 degrees Celsius. If they are warm or the failure clearly exceeded four hours, discard.
- Cooked prawns and cream soup: these are ready-to-eat and high risk. If the failure time cannot be established, discard. Reheating soup does not make prawns safe.
- Cut fruit: discard. It is ready-to-eat and has been handled.
Evidence needed: the data logger or thermometer records, door-opening logs, and any staff statements. If no data exists, the conservative call is to discard all high-risk ready-to-eat items and treat raw meat as suspect. The chef should photograph the thermometer, record times and decisions, and keep the records for the food safety plan.
2. The chef wants to proceed with the wedding using the small cool room and rapid chilling. Evaluate whether this is feasible and outline the operational and communication steps required.

Feasibility depends on volume and time. The small cool room holds roughly one-third of the original load, so it cannot hold all 40 kg chicken, 15 kg prawns, 20 L soup, 10 kg fruit, and 30 kg beef. Rapid chilling can help only if there is enough refrigeration capacity to hold the chilled food afterwards; otherwise the food will warm again.
A workable plan only exists if:
- The suspect ready-to-eat items are discarded and replaced.
- Fresh raw protein is sourced early Saturday morning from an approved supplier.
- The small cool room is reserved for high-risk ready-to-eat items and the menu is simplified to reduce the cold-storage load.
- A refrigerated van or portable cool room can be hired for the function.
If none of these can be arranged before 12:00 pm, the chef should not serve the original menu. The operational steps are:
- Record the failure, temperatures, times, and all discard decisions.
- Notify the owner and the client immediately, explaining the menu change and the reason.
- Contact suppliers for emergency stock and hire refrigeration.
- Rewrite the menu around what can be safely stored and cooked.
- Brief staff on the revised plan and on not using any suspect product.
Communication with the client should be honest and early. Offering a revised menu or partial refund is better than serving unsafe food. The deposit does not create a legal right to serve unsafe food, and the business's food safety obligations override the contract.
