Level 3 Food Safety Certificate Temperature Control and Monitoring 2 — Questions and Answers
Question 1: What is 'blast chilling' and when should it be used?
- Rapidly cooling cooked food from above 63°C to below 8°C within 90 minutes, using a blast chiller, to minimise the time food spends in the danger zone (Correct answer)
- Freezing food immediately after cooking
- Cooling food overnight on a counter
- Putting hot food directly into a standard refrigerator
Correct answer: Rapidly cooling cooked food from above 63°C to below 8°C within 90 minutes, using a blast chiller, to minimise the time food spends in the danger zone
Blast chilling rapidly reduces temperature to prevent bacterial growth — hot food must not be cooled slowly at room temperature or placed hot into a refrigerator, as this allows prolonged danger zone exposure.
Question 2: What temperature should a commercial refrigerator display?
- 1°C to 4°C (Correct answer)
- 5°C to 8°C
- 0°C to 8°C
- Below 0°C
Correct answer: 1°C to 4°C
Commercial refrigerators should operate between 1°C and 4°C for optimal food safety and quality — this is colder than the legal maximum of 8°C, ensuring a safety margin.
Question 3: What is 'cook-chill' and what are its food safety requirements?
- A system where food is cooked, quickly chilled, stored at below 3°C, and reheated to 75°C before service — with strict time and temperature controls (Correct answer)
- A method of cooking without refrigeration
- A technique for raw food preparation
- A low-risk catering method requiring minimal temperature monitoring
Correct answer: A system where food is cooked, quickly chilled, stored at below 3°C, and reheated to 75°C before service — with strict time and temperature controls
Cook-chill is a catering system requiring rapid chilling post-cooking (to below 3°C within 90 minutes), cold storage (below 3°C), and thorough reheating to at least 75°C — strict monitoring is essential.
Question 4: What does 'reheating to 75°C' achieve in food safety?
- It kills most vegetative bacteria that may have multiplied during storage, ensuring the food is safe to eat (Correct answer)
- It improves the flavour of the food
- It meets a legal requirement only — there is no microbiological reason
- It is only required for foods containing poultry
Correct answer: It kills most vegetative bacteria that may have multiplied during storage, ensuring the food is safe to eat
Reheating to 75°C (for at least 2 seconds, or 70°C for 2 minutes in Scotland) kills most vegetative bacteria that may have grown during chilled storage, reducing the risk of food poisoning.
Question 5: What is a 'temperature log' and why is it a HACCP requirement?
- A written record of temperature checks at CCPs, providing evidence that critical limits are being met and enabling corrective action traceability (Correct answer)
- A record only required for Ofsted inspections
- A voluntary best practice document
- A log only required for frozen foods
Correct answer: A written record of temperature checks at CCPs, providing evidence that critical limits are being met and enabling corrective action traceability
Temperature logs are documentary evidence that critical limits are being monitored and met — they are a HACCP requirement (Principle 7: documentation) and essential for demonstrating due diligence.
Question 6: What is 'time as well as temperature control' (TAATC) in UK food hygiene regulations?
- Allowing foods to be held outside temperature control for a limited time (up to 4 hours cumulative) if the food business can demonstrate this is safe (Correct answer)
- A method that replaces temperature control entirely
- A rule only applying to displays in retail shops
- A rule allowing chilled food to be stored at any temperature overnight
Correct answer: Allowing foods to be held outside temperature control for a limited time (up to 4 hours cumulative) if the food business can demonstrate this is safe
UK regulations allow a food business to use time as well as temperature control — food can be held outside temperature control for up to 4 hours total (cumulative, not per occasion) if properly managed.
