How Students Lose Marks (Examiner Pitfalls)
Common mark loss traps and how to write 100% full-mark answers
Pitfall: Confusing 'use by' and 'best before' dates, leading to incorrect food safety decisions.
❌ Weak Answer (Loses Marks):Use by dates are about quality, best before dates are about safety.
✅ 100% Model Answer (Full Marks):Use by dates are safety indicators; food must not be consumed after this date as it may pose a health risk. Best before dates are quality indicators; food may be safe to eat after this date but quality may deteriorate. In food manufacturing, stock rotation must prioritise use by dates to prevent foodborne illness.
Examiner Tip: Always link date labels to food safety legislation and practical stock control.
Pitfall: Failing to identify critical control points (CCPs) correctly in HACCP.
❌ Weak Answer (Loses Marks):CCPs are any steps where we check the food.
✅ 100% Model Answer (Full Marks):A Critical Control Point is a step in the process where control can be applied and is essential to prevent, eliminate, or reduce a food safety hazard to an acceptable level. For example, cooking is a CCP for eliminating pathogenic bacteria, whereas visual inspection is not a CCP because it does not control a hazard.
Examiner Tip: Remember: a CCP must have a measurable limit (e.g., temperature, time) and a monitoring procedure.
Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A batch of cooked chicken is cooled from 90°C to 5°C. The cooling process takes 4 hours. Calculate the average cooling rate in °C per hour and state whether this meets the legal requirement for cooling cooked food.
- 1.Step 1: Identify initial and final temperatures: 90°C and 5°C.
- 2.Step 2: Calculate temperature drop: 90 - 5 = 85°C.
- 3.Step 3: Divide by time taken: 85°C ÷ 4 hours = 21.25°C/hour.
- 4.Step 4: Compare to legal requirement: UK food safety regulations require cooling from 60°C to 10°C within 2 hours (or equivalent). Here, the average rate is 21.25°C/hour, but the critical 60°C to 10°C range must be achieved within 2 hours. Since the total cooling took 4 hours, it likely fails the requirement.
Final Answer: The average cooling rate is 21.25°C per hour, but the batch does not meet the legal cooling requirement because the time from 60°C to 10°C must be within 2 hours, and the total time of 4 hours is too long.
Question: A food manufacturer uses a metal detector as a CCP. The critical limit is set to detect ferrous, non-ferrous, and stainless steel spheres of 2.0 mm diameter. During a routine check, a test piece of 2.5 mm is detected, but a 1.5 mm piece is not. Explain the corrective action required and why.
- 1.Step 1: Identify the deviation: the metal detector fails to detect a 1.5 mm test piece, which is below the critical limit of 2.0 mm.
- 2.Step 2: Follow HACCP corrective action: isolate all product since the last satisfactory check, recalibrate the detector, and re-test.
- 3.Step 3: Investigate the cause (e.g., detector drift, incorrect settings) and document the action.
- 4.Step 4: Dispose of or re-screen affected product to ensure no contaminated product reaches consumers.
Final Answer: The corrective action is to quarantine all product produced since the last good check, recalibrate the metal detector, and re-screen the product. This is necessary because the detector failed to reject a metal piece smaller than the critical limit, posing a physical hazard risk.
