Level 2 Food Hygiene Certificate Food Storage & Temperature Control 2 — Questions and Answers
Question 1: What is the difference between a 'use-by' date and a 'best before' date?
- They mean the same thing
- 'Use-by' is about safety; 'best before' is about quality (Correct answer)
- 'Best before' is about safety; 'use-by' is about quality
- 'Use-by' applies to frozen food only; 'best before' applies to chilled food
Correct answer: 'Use-by' is about safety; 'best before' is about quality
A 'use-by' date is a food safety date — food must not be sold or consumed after this date. A 'best before' date is a quality indicator — food may be safe to eat after this date but its quality may have deteriorated.
Question 2: What temperature should a domestic or commercial freezer maintain to keep food safe?
- -10°C or below
- -15°C or below
- -18°C or below (Correct answer)
- -25°C or below
Correct answer: -18°C or below
Freezers should maintain a temperature of -18°C or below to keep food safe. At this temperature, bacterial growth is prevented and food quality is preserved for longer periods.
Question 3: Which of the following is NOT a safe method of thawing frozen food?
- Thawing in a refrigerator overnight
- Thawing under cold running water
- Thawing in a microwave and cooking immediately
- Thawing on a kitchen counter at room temperature for several hours (Correct answer)
Correct answer: Thawing on a kitchen counter at room temperature for several hours
Thawing food on a counter at room temperature for hours places the outer layers in the temperature danger zone while the inside is still frozen, allowing bacteria to multiply rapidly. Safe thawing uses the fridge, cold water, or microwave (with immediate cooking).
Question 4: Why is it important to store dry goods (flour, rice, cereals) in sealed containers?
- To prevent moisture loss only
- To prevent pest infestation and physical/microbiological contamination (Correct answer)
- To meet fire safety requirements
- Because sealed containers keep food warmer
Correct answer: To prevent pest infestation and physical/microbiological contamination
Storing dry goods in sealed containers prevents contamination from pests (rodents and insects), moisture ingress, and foreign bodies, and also prevents cross-contamination with other foods.
Question 5: How should raw fish be stored in a refrigerator relative to cooked shellfish?
- Raw fish above cooked shellfish
- Raw fish below cooked shellfish on a separate shelf (Correct answer)
- They can be stored together as they are both seafood
- Raw fish should be stored frozen only, never chilled
Correct answer: Raw fish below cooked shellfish on a separate shelf
Raw fish must be stored below cooked shellfish (and all ready-to-eat foods) to prevent drips from raw fish contaminating cooked products, which will not undergo further cooking.
Question 6: Once opened, which of the following high-risk foods has the shortest recommended shelf life in a refrigerator?
- Hard cheese
- Cooked rice (Correct answer)
- Unopened vacuum-packed cooked ham
- Whole uncut fruit
Correct answer: Cooked rice
Cooked rice has one of the shortest recommended shelf lives (24 hours) once cooked because Bacillus cereus spores survive cooking and can rapidly produce toxins at temperatures above 5°C.
