HACCP is a food safety hazard-analysis method developed under Codex Alimentarius, while ISO 22000 is an international, certifiable management system standard that incorporates HACCP principles. Choose HACCP to control process hazards or meet regulations; choose ISO 22000 for organisation-wide governance, supply-chain assurance, and globally recognised certification.
Food businesses often treat HACCP and ISO 22000 as competing options, but they work at different levels. HACCP is a technique for controlling hazards at specific process steps. ISO 22000 wraps that technique inside a management system covering leadership, planning, communication, internal audit and continual improvement. Knowing where one ends and the other begins helps you avoid paying for more than you need, or stopping short of what your customers and regulators expect. This guide sets out scope, structure, certification route and typical users so you can match the right approach to your legal position and market goals.

HACCP: A Hazard-Analysis Method from Codex Alimentarius
HACCP stands for Hazard Analysis and Critical Control Points. It was developed through Codex Alimentarius, the joint FAO/WHO food standards programme, and appears in the Codex General Principles of Food Hygiene. The method gives a food business a logical way to find the hazards that could make food unsafe, decide which are significant, and control them where control matters most.
The method rests on seven principles:
- Conduct a hazard analysis
- Determine the Critical Control Points (CCPs)
- Establish critical limits
- Establish monitoring procedures
- Establish corrective actions
- Establish verification procedures
- Maintain documentation and records
Codex also lays out twelve application steps, from assembling the HACCP team to validating the plan. HACCP depends on prerequisite programmes (PRPs) such as cleaning, pest control, supplier approval and staff hygiene. These cover general hygiene conditions, so the HACCP plan can concentrate on hazards that need specific control.
Many national food regulations require HACCP-based procedures, and the method underpins several GFSI-recognised schemes. However, HACCP is not a stand-alone ISO-style standard, so there is no single “HACCP standard” to certify against. A HACCP certificate is normally issued by a third-party body against a regulation or recognised scheme, which is why its scope and credibility vary between markets. If you need support, see our HACCP certification service.
ISO 22000: A Certifiable Food Safety Management System
ISO 22000:2018, published by the International Organization for Standardization, specifies the requirements for a Food Safety Management System (FSMS). It applies to any organisation in the food chain, from primary producers and processors to packagers, transporters, distributors, retailers and caterers.
The standard follows the ISO High Level Structure, with requirements in Clauses 4 to 10: context, leadership, planning, support, operation, performance evaluation and improvement. It runs on two linked Plan-Do-Check-Act cycles, one for the management system and one for operational hazard control. HACCP principles sit inside the operational clause, so a business implementing ISO 22000 is already carrying out hazard analysis, CCP control and monitoring.
On top of HACCP, ISO 22000 adds requirements the method does not address on its own:
- Top management commitment, a food safety policy and defined responsibilities
- Risk-based planning covering food safety hazards and organisational risks
- Operational prerequisite programmes (oPRPs) for hazards controlled outside CCPs
- A hazard control plan that brings CCPs and oPRPs together
- Defined communication with suppliers, customers and authorities
- Internal audits, management review and continual improvement

Side-by-Side Comparison: Scope, Structure and Who Needs Each
HACCP is the method; ISO 22000 is the management system that contains it. If you implement ISO 22000, you are already implementing HACCP.
| Aspect: | HACCP: | ISO 22000:2018: |
|---|---|---|
| Nature | Hazard-analysis method built on 7 principles | Certifiable standard for a Food Safety Management System (FSMS) |
| Governing document | Codex General Principles of Food Hygiene (CXC 1-1969), HACCP annex | ISO 22000:2018 |
| Scope | Process level: controls significant hazards at specific steps | Organisation-wide: management, planning, operations and improvement across the food chain |
| Structure | 7 principles and 12 application steps | High Level Structure (Clauses 4-10) on the PDCA cycle, with HACCP embedded |
| Operational controls | PRPs and Critical Control Points (CCPs) | PRPs, oPRPs and CCPs, managed through a hazard control plan |
| Management elements | Not required | Leadership, policy, risk-based planning, internal audit, management review, continual improvement |
| Communication | Not specified | Internal and external (supply-chain) communication requirements |
| Certification | No stand-alone standard; verified against a regulation or scheme, often by a third party | Certifiable by accredited certification bodies; internationally recognised |
| Legal and market position | Mandated or expected by many national regulations | Not a legal requirement; valued in tenders, exports and multinational supply chains |
| Who needs it | Any food business handling hazards, especially where regulation requires HACCP; SMEs wanting a focused, cost-effective system | Manufacturers, processors, packagers, distributors and caterers seeking an integrated, certifiable system for export, retail or multi-site operations |
| Integration | None | Shares structure with ISO 9001, ISO 14001 and ISO 45001 |
| Effort and cost | Lower | Higher, with broader scope and annual surveillance audits |
Regional Regulatory Context: Where HACCP Is a Legal Requirement
HACCP is not only a voluntary tool. In many markets it is a legal baseline, and that changes how you should read the choice between HACCP and ISO 22000.
- European Union. Article 5 of Regulation (EC) No 852/2004 requires food business operators to put in place, implement and maintain permanent procedures based on HACCP principles. It applies to businesses at any stage after primary production, and the records required are proportionate to the nature and size of the business. In the EU, HACCP-based procedures are therefore compulsory, while ISO 22000 remains a voluntary step up. Read the full text on EUR-Lex.
- United States. HACCP-based controls apply through several rules, depending on the product. USDA FSIS requires HACCP systems in meat and poultry plants under 9 CFR Part 417. FDA requires HACCP for seafood and juice, and most other food facilities must follow the hazard analysis and risk-based preventive controls rule under FSMA. That rule is HACCP-based but not identical to classic HACCP.
- Saudi Arabia. An SFDA circular dated January 2021 made HACCP mandatory for food and water factories across all regions of the Kingdom. SFDA inspections check that a HACCP system exists and works, and that an effective tracking system is in place. Violations recorded during its 2024 campaign included the absence or ineffectiveness of a HACCP system. Check current requirements directly with the SFDA.
What this means for your choice. Legal HACCP compliance is the minimum in each of these markets, not a competitive advantage. ISO 22000 becomes the differentiator when you export, bid for tenders, supply multinational buyers or need a recognised certificate to show beyond local inspectors. Rules differ by country, product and business type, so confirm your own obligations before deciding. Our team can map them for you through our ISO certification services.
How the Two Fit Together in Daily Operations
Follow a single hazard through both systems. Suppose a dairy identifies pathogen survival as a significant hazard. Under HACCP, pasteurisation becomes a CCP with a critical limit for time and temperature, a monitoring routine, a corrective action if the limit is missed, and records as proof.
ISO 22000 keeps all of that, then asks further questions. Who is accountable for the CCP, and are they trained and authorised to act? How is monitoring equipment calibrated? How are process changes assessed before they are made? What happens when a complaint or audit shows the control is weaker than assumed? These requirements turn a good technical control into a managed, auditable and continually improving system.
The difference between oPRPs and CCPs is also worth understanding. A CCP has measurable critical limits and is usually the last step able to control a hazard. An oPRP is a prerequisite control the hazard analysis identifies as essential, managed with action criteria rather than critical limits, for example allergen changeover cleaning between production runs. HACCP-only systems often treat such controls informally, while ISO 22000 requires them to be identified, monitored and verified.
Choosing the Right Approach for Your Business
Your decision should follow your legal obligations, customer requirements and growth plans:
- HACCP suits small and medium businesses that need an affordable, targeted way to control hazards and meet legal obligations. It is often the right starting point for restaurants, bakeries and small production kitchens.
- ISO 22000 suits organisations that want an integrated food safety management system, with global certification ambitions and tighter supply-chain communication. It is common among exporters, large processors, central kitchens and hotel groups.
- Customer or tender requirements can settle the question. If a buyer asks for a GFSI-recognised scheme such as FSSC 22000, ISO 22000 is the core of that route, so building on it avoids rework.
- Regulatory requirements come first. If your country requires HACCP-based procedures, those obligations apply whether or not you pursue ISO 22000.
- Smaller kitchens and cafés should confirm that Good Hygiene Practices (GHP) are firmly in place first, because both HACCP and ISO 22000 rely on that prerequisite layer.
A useful test is to ask who needs to be convinced. If it is a local inspector, a well-run HACCP system may be enough. If it is an overseas buyer or procurement panel, an accredited ISO 22000 certificate carries more weight.
Moving from HACCP to ISO 22000
A business already running HACCP does not start from zero. Your hazard analysis, CCPs, monitoring records and prerequisite programmes carry across. The work lies in the management-system layer:
- Gap assessment against ISO 22000:2018
- Context and risk planning, including interested parties and scope
- Leadership and policy, with objectives and assigned responsibilities
- Operational upgrade, including oPRPs, a hazard control plan and communication procedures
- Internal audit and management review before the external audit
- Certification audit by an accredited body, followed by annual surveillance audits
Timelines depend on size, existing maturity and the number of sites.
Certification in Practice: Two Examples
- Jeddah-based café: After adopting HACCP certification, the café improved customer satisfaction and reduced service delays through tighter, more consistent kitchen procedures.
- Fresh Dairy Ltd: This mid-sized Kenyan dairy company achieved ISO 22000 certification in 9 months. By upgrading its HACCP plans, training staff and improving traceability, it saw a 30% drop in product complaints, export approval to the Middle East and a 22% revenue increase.

FAQ
Is ISO 22000 the same as HACCP?
No. HACCP is a hazard-analysis method developed under Codex Alimentarius, built on seven principles. ISO 22000 is a certifiable standard for a Food Safety Management System that incorporates HACCP principles and adds leadership, communication, internal audit and continual improvement requirements. HACCP is the method, and ISO 22000 is the system that contains it.
Can a business get ISO 22000 certified without HACCP?
No. HACCP principles are built into ISO 22000, so you must carry out hazard analysis, identify control measures and monitor them. A business already running HACCP has a strong head start. The remaining work is the management-system layer: policy, planning, oPRPs, internal audits and management review. Our ISO 22000 certification team can map those gaps.
Does ISO 22000 certification replace legal HACCP requirements?
Not automatically. Certification shows that an accredited body has audited your management system, but it is not a regulator’s approval. If your country requires HACCP-based procedures, such as under EU Regulation 852/2004, those obligations still apply. Confirm with your national food authority that your ISO 22000 system also meets the local legal requirements.
Is ISO 22000 worth it for a small café or restaurant?
Usually not at the start. A small café typically needs solid Good Hygiene Practices and a well-run HACCP system to meet regulations. ISO 22000 becomes worth the extra effort when you supply hotels or chains, bid for tenders, export or expand to multiple sites, where buyers ask for an accredited certificate.
