What is covered in the Food safety module?

This module covers keeping food safe to eat. It includes the signs and causes of food spoilage by micro-organisms and enzymes, the conditions bacteria need to grow, the main food-poisoning bacteria and the difference between use-by and best-before dates; the principles of food safety, including personal, kitchen and equipment hygiene, preventing cross-contamination, the four Cs and temperature control; and how to buy, store, prepare, cook, cool, reheat and freeze food safely.

What are the four Cs of food safety?

The four Cs are a framework for safe food handling: Cleaning (keep yourself, surfaces and equipment clean), Cooking (cook food thoroughly so the centre reaches above 75 degrees C to destroy bacteria), Chilling (keep cold food below 5 degrees C to slow bacterial growth) and avoiding Cross-contamination (keep raw and ready-to-eat foods apart using separate boards and correct fridge storage).

What temperatures do I need to remember for AQA Food Safety?

Learn these key temperatures: the fridge below 5 degrees C, the freezer at minus 18 degrees C, the danger zone (where bacteria multiply fastest) between 5 and 63 degrees C, cooked food reaching above 75 degrees C at the centre, and hot food held above 63 degrees C. Bacteria grow fastest around body temperature, about 37 degrees C. Reheat food only once and until it is piping hot.

What this module covers
How it fits together
Study tips

The Food safety module of AQA GCSE Food Preparation and Nutrition (8585) is about stopping food making people ill. It is heavy on specific facts: temperatures, the conditions bacteria need, the main food-poisoning bacteria, and the rules for handling food from shop to plate. Learn the numbers precisely and you will pick up marks reliably.

What this module covers

The module has three connected areas:

Food spoilage and bacteria - the causes and signs of spoilage by micro-organisms and enzymes, the four conditions bacteria need (warmth, moisture, food, time), the main food-poisoning bacteria, and use-by versus best-before dates.
Principles of food safety - personal, kitchen and equipment hygiene, preventing cross-contamination, the four Cs, and using temperature control and probes correctly.
Buying, storing and preparing safely - how to buy, store, prepare, cook, cool, reheat, freeze and defrost food safely.

How it fits together

The module starts with why food becomes unsafe (spoilage and the conditions bacteria need), moves to the principles that keep it safe (hygiene, the four Cs and temperature control), and ends with applying those principles at every stage of food's journey. The danger zone (5 to 63 degrees C) and the four conditions for bacterial growth are the ideas everything else hangs on.

Study tips

Memorise the key temperatures. Fridge below 5, freezer minus 18, danger zone 5 to 63, cooked centre above 75, hot holding above 63.
Use the four Cs to structure answers. Cleaning, cooking, chilling and cross-contamination cover almost any safety question.
Apply to specific foods. Be ready to explain safe handling of a chicken curry, raw meat in the fridge, or cooling and reheating leftovers.

Work through the three dot point pages in this module, then test yourself with the module quiz.
