HACCP principles are a systematic way of identifying and controlling food-safety hazards before they make someone ill. HACCP stands for Hazard Analysis and Critical Control Point. It is used throughout food businesses, from preparation kitchens to large-scale manufacturers, and is part of the WJEC Level 1/2 Hospitality and Catering health and safety content. This guide breaks the system into clear steps, using practical examples such as preparing chicken, making a sandwich or serving a dessert. Learning the process will help you explain why controls are needed, not simply memorise a list of terms.
What does HACCP mean?
HACCP is a preventive food-safety system. Preventive means that it aims to stop a problem happening, rather than relying only on checking food at the end.
The name describes its purpose:
- Hazard analysis: identifying anything that could make food unsafe and considering how serious and likely the risk may be.
- Critical control point, or CCP: a stage where control is essential to prevent a hazard, remove it or reduce it to an acceptable level.
For example, cooking poultry is likely to be a critical control point because effective cooking can control harmful microorganisms. Separating raw poultry from ready-to-eat salad is also an important control, because it helps prevent cross-contamination. The exact controls used depend on the food, the equipment, the people preparing it and the premises.
The seven HACCP principles
HACCP is usually explained through seven connected principles. In an exam, use the technical term and then explain what it means in the situation given.
1. Conduct a hazard analysis
First, identify hazards at each stage of the food process. A hazard is something that could cause harm if it is not controlled.
- Biological hazards: harmful microorganisms, such as bacteria, viruses or moulds.
- Chemical hazards: harmful chemicals, cleaning products or unsuitable substances getting into food.
- Physical hazards: objects such as packaging fragments, pieces of broken equipment or jewellery.
- Allergen hazards: an ingredient or trace of an ingredient causing a reaction in someone with an allergy. Allergens must be managed carefully and information must be accurate.
Consider the whole process, including delivery, storage, preparation, cooking, cooling, serving and cleaning. For example, raw meat could contaminate a chopping board during preparation, while a cleaning chemical could contaminate food if it is stored or used incorrectly.
2. Identify the critical control points
Next, decide which steps are critical control points. These are not simply every stage where good hygiene matters. A CCP is a point where a specific control is essential for food safety and where losing control could create a significant risk.
For a cooked dish, a CCP might be the cooking stage because the process is intended to control harmful microorganisms. For a cold ready-to-eat food, keeping preparation hygienic and preventing contact with raw food may be a key control. A business should examine its own process rather than automatically labelling every stage a CCP.
3. Set critical limits
A critical limit is the boundary that separates safe control from loss of control at a CCP. It must be clear and measurable or observable where appropriate. Depending on the process, a limit could relate to time, temperature, appearance, condition, separation or another suitable check.
For example, a kitchen may set a required cooking control and use an appropriate method to check it. Do not invent a number in an exam or revision answer. If a question supplies a critical limit, use it accurately. Food-safety guidance can change, so check current advice from the Food Standards Agency or your teacher rather than relying on an old figure.
4. Monitor the critical control points
Monitoring means carrying out planned checks to make sure a CCP remains within its critical limit. A member of staff may check a process, inspect food or use suitable equipment, depending on the control.
Monitoring should answer three questions:
- What is being checked?
- How and when is it checked?
- Who is responsible for checking and recording it?
For instance, a person preparing a dish may record a cooking check or confirm that raw and ready-to-eat foods have been kept separate. Regular monitoring helps staff find a problem before unsafe food is served.
5. Take corrective action
Corrective action is what happens when monitoring shows that a critical limit has not been met. The response should deal with the immediate food-safety problem and help prevent it happening again.
Depending on the situation, action might include stopping the process, continuing a process safely if the procedure allows it, isolating or disposing of affected food, cleaning and disinfecting equipment, reporting the problem and checking why it occurred. A vague statement such as “sort it out” is not enough. Explain what would happen to the food and what would happen to the process.
6. Verify that the system works
Verification means checking that the HACCP system is being followed and is effective. This is different from monitoring. Monitoring is a routine check at a CCP. Verification reviews whether the overall system and its records are working properly.
Verification could include reviewing monitoring records, observing staff practices, checking equipment and reviewing procedures after a change to the menu or premises. If verification finds repeated problems, the HACCP plan may need to be improved.
7. Keep records and documentation
Documentation is the written or electronic evidence of the HACCP system. Records may show hazards identified, CCPs, critical limits, monitoring results, corrective actions and verification checks.
Records should be accurate, clear and completed at the correct time. They help staff communicate, demonstrate that controls are being followed and identify patterns such as repeated equipment or training problems. Documentation is useful only if it reflects what actually happened.
How the principles work together
The seven principles form a cycle rather than seven unrelated facts. A kitchen identifies a hazard, chooses a critical control point, sets a limit, monitors it, takes action if control is lost, verifies the system and keeps records. Verification may reveal that a hazard was missed or that a control is not practical, so the plan can be reviewed.
HACCP also depends on everyday hygiene procedures. Staff training, personal hygiene, cleaning, pest control, suitable equipment and safe storage support the system. However, when revising this topic, keep your answer focused on the HACCP principle the question asks about.

Quick retrieval checklist
- Can you expand HACCP correctly?

- Can you describe suitable corrective action when control is lost?
- Can you explain why accurate records matter?
Frequently asked questions
Is every hygiene check a critical control point?
No. A CCP is a stage where control is essential to prevent, remove or reduce a food-safety hazard to an acceptable level. Other hygiene controls still matter, but they are not automatically CCPs.
What is the difference between monitoring and verification?
Monitoring is a routine check of a critical control point. Verification is a wider review to confirm that the HACCP system is being followed and works effectively.
Why are records important in HACCP?
Records provide evidence of checks, show whether corrective action was needed and help a food business identify repeated problems.
