Food safety and hygiene is the foundation of SQA National 5 Practical Cookery. The SQA is clear that safety and hygiene must permeate the whole course, so these rules are demonstrated and marked in the practical activity and examined in the question paper. This page maps the area and shows how the parts connect.
The key topics in food safety and hygiene
- Personal hygiene
- Handwashing and when to do it, clean protective clothing, hair and jewellery rules, covering cuts with blue plasters, and why an ill cook must not prepare food for others.
- Kitchen and equipment hygiene
- Cleaning as you go, sanitising work surfaces, washing up in the correct order (cleanest first, greasiest last), using clean cloths, and the safe disposal of waste to keep pests away.
- Food storage and temperature control
- The four conditions bacteria need (food, warmth, moisture, time), the danger zone, fridge and freezer temperatures, storing raw meat below ready-to-eat food, and the safe cooking, cooling and reheating of food.
- Preventing cross-contamination
- What cross-contamination is, its three routes (direct contact, hands and equipment), and how to prevent it with separation, colour-coded boards and knives, and thorough cleaning.
How the topics connect
The four parts share one purpose: control bacteria. Bacteria come from the cook (personal hygiene), build up in a dirty kitchen (environment), multiply when warm (temperature control), and spread between foods (cross-contamination). The same key numbers appear again and again, and the same idea, that ready-to-eat food is never cooked again, drives both the storage rules and the cross-contamination rules.
How to study this area
- Learn the rule and its reason together. The question paper asks you to explain, so a rule with no reason loses marks. Pair every habit with what bacteria it stops.
- Memorise the key numbers. Fridge 0 to 5 degrees Celsius, freezer minus 18 degrees, core cooking temperature at least 75 degrees, danger zone 5 to 63 degrees.
- Practise scenarios. Storing a shop, preparing a chicken salad, cooling leftovers: scenario questions are where the marks are.
- Use it in the practical. Demonstrate hygiene from the start of the practical activity, because clean working is marked directly.
For the official course specification
The SQA publishes the full National 5 Practical Cookery course specification, specimen question paper and coursework task at sqa.org.uk. Always revise from the current specification, because the course was updated for session 2026-27 (the assignment was removed and the marks rebalanced).
