The Walk-In Cooler Failure Over a Long Weekend
A 90-seat restaurant closes Friday at 23:00 for a three-day holiday weekend. The walk-in cooler holds 200 kg of raw chicken, 60 kg of raw ground beef, 40 L of milk, 30 kg of cooked rice and 25 kg of sliced deli meat. The cooler has a temperature alarm, but it is routed to the manager's phone, which is turned off. On Monday at 08:00 the kitchen manager opens the cooler and finds the temperature at 14 °C; condensation is running down the walls and the milk cartons feel cool but not cold. She does not know how long the cooler was above 4 °C. The restaurant opens at 11:00 and the first delivery is due at 10:00.
1. Decide what can be kept and what must be discarded, and justify each decision.

With an unknown time above 4 °C, the default is to discard high-risk foods unless there is reliable evidence they stayed safe.
- Raw chicken and raw ground beef: discard. At 14 °C for an unknown period, pathogens such as Salmonella and E. coli O157:H7 could have multiplied substantially; smell and touch are not reliable.
- Milk: discard. It is a high-risk, low-acid liquid and has clearly been above 4 °C.
- Cooked rice: discard. Bacillus cereus is a real risk in cooked rice held warm, and reheating does not destroy the toxin.
- Sliced deli meat: discard. Ready-to-eat meat supports Listeria growth and is eaten without a kill step.
- What can be kept: intact, unopened, shelf-stable items and whole produce that was not cut; check and clean the unit. Nothing in this cooler qualifies as safe high-risk food without time-temperature records, which do not exist. The manager should photograph, record temperatures and quantities, and keep the discard log for the authority and insurer.
2. What does the absence of usable monitoring records mean for the restaurant's food safety plan, and how should the plan be fixed?
Read the worked answer
Monitoring is a core element of a food safety plan: a limit without a check is not a control. Here the alarm existed but was routed to a phone that was off, so the control was not functional. The plan failed at monitoring and at corrective action. Fixes:
- Alarm routing: send alerts to at least two people and to a monitored service, with an escalation list.
- Remote monitoring: a data logger that records continuously and can be downloaded.
- Pre-holiday checklist: verify cooler performance, clear out unnecessary stock, and designate someone on call.
- Written corrective action: if the cooler exceeds 4 °C for more than a defined time, discard high-risk food; do not guess.
- Records: daily temperature logs plus alarm logs, reviewed weekly by the manager.
- Verification: periodic review of logs and a test of the alarm system. The authority will expect to see that the plan is followed in practice, not just written.
3. The 10:00 delivery arrives and the manager needs food for the 11:00 service. What should she do about receiving and about the day's menu?
Read the worked answer
She should receive the delivery only after checking it: vehicle temperature, product temperature (4 °C or below for chilled, frozen solid for frozen), packaging integrity, dates and signs of thawing. If the delivery is out of specification, reject it and record why. She should not use the delivery to backfill a cooler that has not been cleaned and returned to temperature; the unit must be cleaned, sanitized and verified at 4 °C or below first, with product staged elsewhere.
For the menu, the honest move is to reduce the menu to items that do not depend on the discarded stock, or to delay opening the affected dishes. Substituting questionable product to protect the 11:00 service is exactly the pressure that causes outbreaks. The manager should tell the owner, document the loss, and use the event to test the revised plan.
