Cooking and Kitchen Safety
Core concepts
Understand food hygiene and the causes of foodborne illness - bacteria such as Salmonella, Campylobacter, E. coli, and Listeria, plus cross-contamination from raw to cooked food. Know the temperature danger zone (roughly 5–63 °C) and the need to keep hot food hot and cold food cold. Learn personal hygiene (handwashing, clean clothing, hair tied back), safe knife handling, and correct use of equipment. Know fire safety: never put water on a fat fire; use a fire blanket or lid. Understand electrical safety, gas safety, and safe storage of cleaning chemicals. Know first aid for cuts, burns, and scalds.
Traps to watch
- The danger zone is the range where bacteria multiply fastest; freezing does not kill bacteria, it only stops growth.
- Reheating food more than once increases risk; leftovers should be cooled quickly and refrigerated.
- Water on a chip-pan fire spreads flames; smothering removes oxygen.
- A sharp knife is safer than a blunt one because it is less likely to slip.
Worked example
A candidate is asked why raw chicken should not be chopped on the same board as salad. Answer: raw chicken may carry Salmonella or Campylobacter; the salad is eaten uncooked, so bacteria transfer directly to the food and are not destroyed by heat. Use separate colour-coded boards or wash thoroughly between uses.
Rule of thumb
For every hygiene question, trace the route of contamination and then state how to break it - separate, cook, chill, or clean.
