Elective Group A – Hygiene: Food Safety from Receipt to Service
The concepts you must know
Hygiene electives test the full food safety chain: personal hygiene, safe food handling, temperature control, cross-contamination, cleaning and sanitising, pest control and the legal framework. Know the temperature danger zone (5°C to 60°C), the two-hour/four-hour rule for ready-to-eat food, and the requirement to keep cold food at or below 5°C and hot food at or above 60°C. Understand the difference between cleaning (removing visible dirt) and sanitising (reducing microorganisms to safe levels). Learn the main causes of foodborne illness: poor personal hygiene, inadequate cooking, improper cooling, cross-contamination and unsafe holding temperatures.
Traps to watch
Many candidates confuse food poisoning with food spoilage; spoiled food is not always the cause of illness, and food carrying pathogens may look, smell and taste normal. Another trap is allergen management: allergens cannot be 'cooked out', and cross-contact must be prevented through separate utensils and surfaces. Questions on handwashing may test timing; hands must be washed after handling raw food, after using the toilet, after touching the face or bins, and before handling ready-to-eat food. Watch for items that suggest wiping a board with a dry cloth, which spreads bacteria rather than removing them.
Worked example
A cook receives frozen chicken at 2°C and leaves it on the bench to thaw for service. The trap is thawing at room temperature. Correct practice is to thaw in the refrigerator at or below 5°C, in a microwave if cooking immediately, or under cold running water as a last resort, and to keep raw juices away from ready-to-eat items.
Rule of thumb
If in doubt, throw it out; and keep raw and ready-to-eat separate at every step.
