The Temperature Log Gap
During a Year 12 practical, your team prepares chicken rissoles and a cold rice salad for a school lunch service of 60 people. At 10:15 am the chicken mince is removed from the cool room (recorded at 3°C). At 10:50 am the rissoles are shaped and placed in the oven. The rice salad is cooked, cooled on the bench, and mixed with dressing at 12:10 pm. At 12:30 pm a teacher asks to see your temperature records. Your log shows the cool room reading and the oven setting of 180°C, but no internal cooking temperature, no cooling record for the rice, and no holding temperature for either dish.
1. Identify the critical control points that are missing from the log and explain the food safety risk associated with each gap.

Three control points are missing.
Internal cooking temperature of the rissoles. Oven setting is not the same as food temperature. Poultry mince must reach at least 75°C in the centre to destroy pathogens such as Salmonella. Without a probe reading, you cannot demonstrate the hazard was controlled.
Cooling record for the rice. Cooked rice is a classic risk food for Bacillus cereus. If it sits on the bench, it passes through the danger zone (5°C–60°C) slowly. The safe approach is to cool it rapidly, ideally to below 5°C within a short window, and record the time and temperature at intervals.
Holding temperature. Once the rissoles are cooked and the salad is dressed, both must be held either hot (above 60°C) or cold (below 5°C) until service. No holding record means you cannot show the food stayed out of the danger zone between 12:10 pm and service.
The judgement being tested is that a temperature log is evidence of control, not a decoration. Recording the oven dial is a common student error because it feels like a temperature record but does not measure the food.
2. The rice was left on the bench from 11:40 am to 12:10 pm before dressing. Evaluate whether this is acceptable and recommend a corrective action.
Read the worked answer
Thirty minutes on the bench is a borderline situation. The rice was likely still hot when removed from the stove at about 11:40 am, so it may have remained above 60°C for part of that time. However, without a probe reading at 11:40 am and 12:10 pm, you cannot prove it stayed out of the danger zone.
The safe evaluation is: do not assume it was fine. The absence of evidence is treated as a failure of control in a food business.
Recommended corrective action: if the rice cannot be verified as safe, it should not be served. For future service, spread the rice thinly on a shallow tray, cool it quickly (for example in front of a fan or in a blast chiller), and record the temperature at the start and end of cooling. Dressing should be added only once the rice is cold. The reasoning is that Bacillus cereus spores survive cooking, and slow cooling allows them to germinate and produce toxin that reheating does not destroy.
