Power Cut, 40 kg of Rice, and a 1:30 pm Bell
It is 1:05 pm at a government higher secondary school and 250 students are waiting for lunch. Forty kilograms of rice was cooked at 8:30 am and split into three 20-litre patilas with tight lids. The power failed at 9:00 am; the cold room did not come back on and the kitchen has stayed at 32–34 °C all morning. Two patilas were never refrigerated at all. The third went into the cold room at 9:00 am and is still reading 14 °C on the probe. The cook proposes to reheat everything together for ten minutes in the kadhai, 'until it is steaming', and serve it with dal. Reheating this volume to a safe core temperature would take about 25 minutes, and the meal is due at 1:30 pm. The store has 300 bananas, 40 kg of wheat flour, 5 kg of dal and cooking oil.
1. Should the rice be served? Give the decision with the temperature and time reasoning behind it.

No. All three patilas should be discarded.
Reasoning:
- Cooked rice is a temperature-control-for-safety food. Between 5 °C and 60 °C it is in the danger zone, and the working rule is a maximum of 2 hours cumulative in that zone (with 4 hours as the absolute outer limit before discard in most guidance).
- The two unrefrigerated patilas sat at 32–34 °C from 8:30 am to 1:30 pm - 5 hours in the danger zone. They are outside every limit.
- The third patila is not safe either. At 14 °C it never reached 5 °C, so it too spent roughly 4.5 hours above the safe cold-holding temperature. 'Colder than the others' is not the same as safe.
- Reheating does not rescue this. The 25 minutes needed also makes the 1:30 pm service impossible without pushing the food further into the danger zone.
What to serve instead: fresh chapati or puri from the 40 kg flour, dal, and the bananas. That is a complete, culturally normal meal, it can be produced in 25 minutes with the staff available, and it protects 250 children from a risk that has no upside. The decision is documented in the kitchen register with times and probe readings.
2. The principal argues that thorough reheating kills any bacteria, so the rice is fine. How do you respond, and what corrective steps go into next month's plan?
Read the worked answer
Response to the principal: reheating kills vegetative bacteria but not everything that makes people ill. Rice is the classic source of Bacillus cereus. Its spores survive cooking, germinate when the rice cools slowly, and produce cereulide, an emetic toxin that is heat-stable to well over 100 °C. No amount of boiling destroys it. Staphylococcus aureus toxins behave the same way. So 'it was boiled twice' is not a safety argument for rice held warm for hours.
Corrective actions for next month:
- Cook-chill: cook in batches sized to be served within 2 hours; if not, spread rice in shallow trays and chill to below 5 °C within 90 minutes.
- Hot holding: hold cooked rice above 60 °C in a hot case or insulated container, not in lidded patilas at room temperature.
- Power failure protocol: a written rule that no TCS food stays above 5 °C for more than 2 hours cumulatively, with a named person checking and signing a time-temperature log.
- Probe thermometer kept in the kitchen with calibration checks.
- Backup menu (chapati/dal/banana, poha, upma) agreed in advance so no one improvises under pressure.
3. Write the incident note the cook should make in the kitchen register, and explain why a written record matters here.
Read the worked answer
Register entry (factual, timed, signed):
- 08:30 - 40 kg rice cooked, divided into three 20 L patilas.
- 09:00 - power failure; cold room off; kitchen ambient 32–34 °C.
- 09:00 - patila 3 placed in cold room.
- 13:00 - probe check: patilas 1 and 2 at 33 °C, patila 3 at 14 °C. All three held above 5 °C for more than 4 hours.
- 13:05 - decision taken by head cook and principal: all rice discarded, not served.
- 13:10 - 3 patilas denatured with detergent and marked 'not for service', then disposed as per waste procedure.
- 13:15–13:40 - replacement meal (chapati, dal, banana) prepared and served to 250 students.
- Signed: head cook, principal.
Why it matters: the note proves the decision was made on evidence, protects the school if a child later reports illness from something else, and gives the next cook a real data point for the 2-hour rule. It also shows an examiner or inspector that the kitchen understands why it discarded food, not just that it did - which is the difference between a trained kitchen and a lucky one.
