Quick Answer
The 7 principles of HACCP provide the scientific framework for food safety management. They guide food businesses through identifying hazards, establishing critical controls, and maintaining records. A properly designed HACCP plan based on these principles is legally required under EU food safety law and enforced in Ireland by the Food Safety Authority of Ireland (FSAI).
Key Facts Table
| HACCP Principle | Action Required |
| 1. Hazard Analysis | Identify all biological, chemical, physical hazards |
| 2. Identify CCPs | Determine Critical Control Points in the process |
| 3. Establish Critical Limits | Set min/max values for each CCP |
| 4. Monitor CCPs | Record measurements at defined intervals |
| 5. Corrective Actions | Define responses when limits are breached |
| 6. Verification | Confirm the HACCP system is working |
| 7. Documentation | Maintain all records as evidence of compliance |
Introduction
HACCP stands for Hazard Analysis and Critical Control Points. It is the internationally recognised, scientifically validated approach to food safety management that forms the backbone of food safety law in Ireland and across the EU. Every food business – from a café to a large food manufacturer – must implement a system based on the 7 HACCP principles. Understanding these principles is not just a legal requirement; it is the foundation of a food-safe workplace. Irish HACCP offers HACCP Food Safety Level 1 & 2 training that covers every principle in practical, accessible detail.
The 7 Principles of HACCP: A Full Explanation
Principle 1 – Conduct a Hazard Analysis
The first step in any HACCP plan is identifying all potential food safety hazards associated with each stage of your food production process. Hazards fall into three categories:
- Biological: Bacteria (Salmonella, E. coli, Listeria), viruses, parasites
- Chemical: Cleaning products, pesticide residues, allergens, additives
- Physical: Glass fragments, metal shavings, bone, packaging materials
A thorough HACCP risk assessment examines every ingredient, process step, and piece of equipment to determine what could go wrong and how likely it is to cause harm.
Principle 2 – Identify Critical Control Points (CCPs)
A Critical Control Point is any step in the food process where a control measure can be applied to prevent, eliminate, or reduce a food safety hazard to an acceptable level. Common CCPs include:
- Cooking (killing pathogens through heat)
- Chilling (slowing bacterial growth)
- Metal detection (identifying physical contamination)
- Pasteurisation (eliminating pathogens in liquids)
Not every step is a CCP. A systematic decision tree approach helps identify which steps genuinely require CCP designation.
Principle 3 – Establish Critical Limits
For each CCP, you must define the specific values that must be achieved to ensure the hazard is controlled. Examples:
- Cooked poultry must reach a core temperature of 75°C
- Chilled foods must be stored at 5°C or below
- Hot-held food must be kept at 63°C or above
Critical limits must be measurable, scientifically justified, and documented in the HACCP plan.
Principle 4 – Establish Monitoring Procedures
Monitoring is how you verify that each CCP remains within its critical limits during normal operations. This involves:
- Designating staff responsible for monitoring
- Defining the frequency of monitoring (e.g., every 2 hours)
- Specifying the measurement tools to be used (thermometers, pH meters)
- Recording all monitoring data in logs
Regular monitoring creates the evidence trail that inspectors look for.
Principle 5 – Establish Corrective Actions
When monitoring reveals that a critical limit has been breached, a pre-defined corrective action must be taken immediately. Examples:
- If a cooked product has not reached 75°C – continue cooking or discard
- If a chilled product has risen above 5°C – assess for safety, discard if in doubt
All corrective actions must be recorded, including what happened, what was done, and who made the decision.
Principle 6 – Establish Verification Procedures
Verification confirms that your HACCP system is actually working as intended. Verification activities include:
- Internal audits of HACCP records
- Microbiological testing of food products
- Calibration of monitoring equipment
- Review of customer complaints
The FSAI recommends that HACCP verification be conducted at regular intervals and whenever significant process changes occur.
Principle 7 – Establish Documentation and Record Keeping
The final principle requires that all HACCP activities be fully documented. Required records typically include:
- The written HACCP plan itself
- Hazard analysis worksheets
- CCP monitoring logs
- Corrective action records
- Verification and audit reports
- Staff training certificates (including HACCP course records from https://www.irish-haccp.ie/)
HACCP Risk Assessment: Practical Application
A HACCP risk assessment evaluates each identified hazard against two factors:
- Likelihood – How probable is it that this hazard will occur?
- Severity – How serious would the consequences be if it did occur?
High likelihood + high severity = highest priority for CCP designation and control.
In our experience, food businesses that invest in structured HACCP training – such as the HACCP Food Safety Level 1 & 2 course available at https://www.irish-haccp.ie/ – are significantly better equipped to carry out meaningful risk assessments and maintain compliant HACCP plans.

Frequently Asked Questions
Q1: What are the 7 principles of HACCP? They are: (1) Conduct a hazard analysis, (2) Identify CCPs, (3) Establish critical limits, (4) Establish monitoring, (5) Establish corrective actions, (6) Establish verification, (7) Establish documentation.
Q2: Is a HACCP plan legally required in Ireland? Yes. EU Regulation 852/2004 requires all food businesses in Ireland to have a HACCP-based food safety management system in place.
Q3: What is a HACCP risk assessment? A HACCP risk assessment evaluates food safety hazards based on their likelihood of occurrence and their potential severity, to determine which require CCP designation.
Q4: How do I learn to create a HACCP plan? The HACCP Food Safety Level 1 & 2 course from Irish HACCP teaches you how to develop, implement, and maintain a HACCP plan. Visit https://www.irish-haccp.ie/.
Q5: How often should a HACCP plan be reviewed? At minimum annually, and whenever there are changes to menu, process, equipment, suppliers, or food safety law.
