- The containers are not food grade
- Chemical residue can remain in the container and contaminate food, and it creates confusion about the container's contents (Correct answer)
- The containers are too large for food

Correct answer: Chemical residue can remain in the container and contaminate food, and it creates confusion about the container's contents
Chemical residues can persist in containers even after washing, potentially contaminating food. Additionally, using chemical containers for food creates confusion and the risk of someone pouring chemicals into what they think is a food container.
Question 2: What is the maximum shelf life for leftover cooked rice stored at 4°C?
- 24 hours
- 3 days
- 1 day from preparation (Correct answer)
- 7 days
Correct answer: 1 day from preparation
Cooked rice should be used within 1 day (24 hours) when stored at 4°C due to the risk of Bacillus cereus, which forms heat-resistant spores. Rice must be cooled rapidly and refrigerated promptly after cooking.
Question 3: How should raw eggs be stored in a food premises?

Eggs must be stored in the refrigerator at 4°C or below in their original carton, which protects them from damage, absorbing odors, and moisture loss. The carton also displays the best before date.
Question 4: What is the proper way to store food in a walk-in cooler?

Correct answer: On shelves at least 15 cm off the floor, covered or in sealed containers, with raw products below ready-to-eat items
Food must be stored on shelves (at least 15 cm off the floor), covered or sealed to prevent cross-contamination and drying, with raw products positioned below ready-to-eat items to prevent drip contamination.
Question 5: Why is it important to keep dry storage areas well-ventilated?
- For employee comfort only
- Good ventilation controls humidity, prevents mold growth, and helps maintain consistent temperatures (Correct answer)
- Ventilation is not important for dry storage
- To keep the area smelling fresh
Correct answer: Good ventilation controls humidity, prevents mold growth, and helps maintain consistent temperatures
Proper ventilation in dry storage controls humidity levels, prevents condensation and mold growth on food packaging, and helps maintain temperatures within the ideal range of 10°C–21°C.
Question 6: What should a food handler do when they find a food item without any date marking in the cooler?
- Smell it to determine if it is still good
- When in doubt, throw it out — undated food should be discarded if its age and safety cannot be determined (Correct answer)
- Use it immediately before it goes bad
- Add a date label with today's date and continue storing it
Correct answer: When in doubt, throw it out — undated food should be discarded if its age and safety cannot be determined
Food without date marking cannot be verified as safe. The item should be discarded and the issue reported to prevent recurrence. 'When in doubt, throw it out' is a fundamental food safety principle.
