Food preparation and safety: hygiene, food spoilage and poisoning, kitchen safety and safe storage of food

What this module demands

Food safety is the part of the syllabus where a wrong answer could make someone ill, so SEAB (6073) tests it carefully. You need to explain the rules of personal and kitchen hygiene, describe how food spoils and how food poisoning happens, state the conditions bacteria need, prevent the common kitchen accidents, and store food correctly. The written Paper 1 asks for these as recall and short explanation, and the coursework food study marks you on safe, hygienic practice throughout your practical work. This overview links every dot point in the module.

Keeping bacteria off food

Start with food hygiene and personal cleanliness. The aim is to stop harmful bacteria reaching food: wash hands with soap at the right moments, tie back hair, wear a clean apron, cover cuts, keep surfaces and utensils clean, and use separate chopping boards for raw and cooked foods to prevent cross-contamination. These habits remove the routes by which bacteria get onto food.

Food spoilage and food poisoning explains why food goes off and how it makes us ill. Spoilage is caused by moulds, yeasts, bacteria and natural enzymes and shows as changes in smell, taste, colour and texture. Food poisoning is illness from eating food contaminated with harmful bacteria or their toxins. The key fact is the conditions bacteria need to multiply: warmth, moisture, food and time, with the danger zone between about 5 degrees C and 60 degrees C.

Working safely and storing food

Kitchen safety and accident prevention covers the common hazards: cuts, burns and scalds, fires and falls, and how to prevent each. Most accidents come from rushing, so the safe cook works calmly, uses equipment correctly, turns pan handles inward and clears spills at once.

Safe storage of food ties it together: keep the fridge at about 0 to 5 degrees C and the freezer at about minus 18 degrees C, store raw meat below ready-to-eat foods so juices cannot drip down, keep dry goods airtight, rotate stock so older items are used first, and follow date labels (use-by for safety, best-before for quality).

How this module is examined

• State hygiene rules with reasons. Recall questions ask for rules; the marks come from adding why, such as "use separate boards to stop bacteria from raw meat cross-contaminating cooked food".
• Apply the danger zone. Questions describe food left out and ask why it is unsafe. Name the danger zone (about 5 to 60 degrees C) and the four needs of bacteria.
• Read date labels and storage. Data-response questions show a label or a fridge and ask where a food should go or whether it is safe to eat.
