HACCP Explained: The 7 Principles in Plain English
Every food business in Ireland is legally required to operate a food safety management system based on HACCP. It sounds technical, but the idea behind it is simple — here are the seven principles in plain English.
What HACCP actually means
HACCP stands for Hazard Analysis and Critical Control Points. At its heart it is a structured way of thinking: look at everything that could make food unsafe, work out where you can stop those hazards, and put controls in place at exactly those points. It is preventive, not reactive — the goal is to keep problems from happening rather than to catch them afterwards.
Under EC Regulation 852/2004, food business operators in Ireland must put in place, implement and maintain procedures based on HACCP principles. The Food Safety Authority of Ireland (FSAI), working with local Environmental Health Officers (EHOs), oversees how well businesses do this.
The seven principles
HACCP is built on seven steps that flow logically from one to the next.
1. Conduct a hazard analysis
Identify the biological, chemical and physical hazards that could affect your food — from harmful bacteria to allergens to foreign objects. You can only control what you have first identified.
2. Determine the critical control points (CCPs)
A CCP is a step where control is essential to prevent or remove a hazard — for example, cooking, chilling or hot-holding. These are the points where getting it wrong genuinely makes food unsafe.
3. Establish critical limits
For each CCP, set a measurable limit that must be met, such as a minimum cooking temperature or a maximum chilled storage temperature. Our guide to food safety temperature control covers the key numbers.
A critical limit turns a vague intention — "cook it properly" — into something you can actually measure, record and prove.
4. Establish monitoring procedures
Decide how you will check that each CCP stays within its limits: who measures it, how, and how often. Monitoring is what tells you a control is working before food reaches a customer.

5. Establish corrective actions
Plan in advance what you will do when a critical limit is breached — discard the affected food, re-cook it, or adjust the process. Knowing the response before a failure happens keeps a small problem from becoming a serious one.
6. Establish verification procedures
Check that the whole system is actually working — for example by reviewing records, calibrating thermometers and reviewing the plan when menus or processes change. Verification is the quality check on your quality checks.
7. Establish documentation and record-keeping
Keep clear, honest records. Documentation is your evidence that the system is being followed, and it is the first thing an EHO will ask to see during an inspection.
Making HACCP work day to day
HACCP is not a folder that sits on a shelf. It only protects customers when it lives in the daily routine of the kitchen — temperatures checked, fridges logged, allergens managed. The most reliable way to embed it is to make sure every member of staff understands the principles, which is exactly what food hygiene training delivers.

Key takeaways
- HACCP is a preventive system: find hazards, control them at critical points.
- Irish food businesses must operate HACCP-based procedures under EC Reg 852/2004.
- The seven principles run from hazard analysis through to record-keeping.
- Critical limits make controls measurable; monitoring proves they are met.
- Records are your evidence of compliance for an EHO inspection.
Prerequisite programmes come first
HACCP does not stand alone. It sits on top of a set of basic good-practice routines known as prerequisite programmes — the foundations that make a HACCP plan workable. These include cleaning and sanitation, pest control, personal hygiene, staff training, and proper waste management. If the foundations are weak, no amount of paperwork at the critical control points will keep food safe.
Think of prerequisites as keeping the whole kitchen clean and orderly, and HACCP as the targeted controls layered on top. Both are needed, and an Environmental Health Officer will look at both.
Keeping the plan alive
A common mistake is to write a HACCP plan once and never revisit it. But menus change, suppliers change and equipment ages. The plan should be reviewed whenever something significant changes, and at regular intervals regardless. A living plan that reflects how the kitchen actually works is worth far more than a perfect document that no longer matches reality. Regular staff training is what keeps the principles fresh in everyone's mind between reviews.
The bottom line
HACCP can sound intimidating, but stripped back it is just disciplined common sense applied to food safety. Get the seven principles into your daily routine and trained into your team, and you have a system that protects customers and stands up to inspection.
