What this dot point is asking
CCEA wants you to explain how food is kept safe from purchase to plate: preventing cross-contamination, personal, kitchen and storage hygiene, the safe temperatures for cooking, chilling and reheating, the HACCP system of hazard control, and the role of food-safety legislation and enforcement.
Hygiene and cross-contamination
Personal hygiene: wash hands thoroughly before handling food and after the toilet, handling raw meat or touching the face; wear clean protective clothing; tie back hair; cover cuts with a blue waterproof dressing; and do not handle food when ill with sickness or diarrhoea. Preventing cross-contamination: keep raw and ready-to-eat foods separate, use separate, colour-coded chopping boards and utensils, store raw meat below ready-to-eat foods in the fridge, and clean and sanitise surfaces and equipment.
HACCP, legislation and enforcement
Food safety is also backed by legislation and enforcement. Food businesses must by law produce safe food, follow good hygiene practice and operate a HACCP-based system; environmental health officers inspect premises, and the Food Standards Agency oversees food safety. CCEA expects you to connect everyday hygiene practice with this formal management and regulatory framework.
Examples in context
Example 1. Colour-coded boards in a kitchen. A professional kitchen uses red boards for raw meat, blue for raw fish and green for salad and fruit, with separate knives, so bacteria from raw meat never reach ready-to-eat food. This simple system prevents cross-contamination, applying the hygiene principles that flow from the microbiology of food poisoning.
Example 2. The fridge layout rule. Storing raw meat on the bottom shelf, below ready-to-eat foods, means any drips cannot fall onto food that will not be cooked. Combined with keeping the fridge below 5 degrees and using date labels, this controls both cross-contamination and temperature, showing safe storage in practice.
Try this
Q1. State the core temperature to which food should be cooked to destroy bacteria. [1 mark]
- Cue. At least 75 degrees Celsius.
Q2. Describe two ways of preventing cross-contamination in the kitchen. [2 marks]
- Cue. Any two of: separate raw and ready-to-eat foods, use colour-coded boards, store raw meat below ready-to-eat food, clean and sanitise surfaces.
Q3. Explain what HACCP is used for. [2 marks]
- Cue. A preventive food-safety system that identifies hazards and controls them at critical control points, with safe limits, monitoring and records.

An 8-mark answer needs measures across hygiene, cross-contamination and temperature control.
Personal hygiene: wash hands thoroughly before handling food and after using the toilet, handling raw meat or touching the face; wear clean protective clothing; tie back hair; cover cuts with blue waterproof dressings; and do not handle food when ill with sickness or diarrhoea.
Preventing cross-contamination: keep raw and ready-to-eat foods separate; use separate, colour-coded chopping boards and utensils; store raw meat below ready-to-eat foods in the fridge; and clean and sanitise surfaces and equipment.
Temperature control: cook food thoroughly to a core temperature of at least 75 degrees Celsius to destroy bacteria; keep chilled food below 5 degrees and hot food above 63 degrees; cool leftovers quickly and refrigerate; reheat only once and to at least 75 degrees; and defrost frozen food fully before cooking. Avoid leaving food in the danger zone (5 to 63 degrees).
Storage and stock: store food correctly, use date labels and stock rotation (first in, first out), and keep the kitchen clean to prevent pests.
Markers reward measures across all three areas (personal and kitchen hygiene, cross-contamination, temperature control), with correct temperatures, for the higher marks.
CCEA A2 20204 marksExplain what is meant by HACCP and how it is used to control food-safety hazards.Show worked answer →
A 4-mark answer needs what HACCP is and how it works.
HACCP stands for Hazard Analysis and Critical Control Points. It is a systematic, preventive food-safety management system used by food businesses to identify hazards and control them before they cause harm, rather than relying on testing the finished product.
The business analyses each step of its process to identify hazards (biological, chemical or physical), determines the critical control points where a hazard can be prevented, eliminated or reduced (such as cooking or chilling), sets safe limits (for example a core temperature of 75 degrees Celsius), monitors those points, and takes corrective action and keeps records when limits are not met.
Markers reward the meaning of HACCP, that it is a preventive system identifying and controlling hazards at critical control points, and at least one example such as setting and monitoring a safe cooking temperature.
