HACCP vs ISO 22000 vs FSSC 22000: Which Certification Do You Actually Need?
The short answer: HACCP is a method, ISO 22000 is a management system, and FSSC 22000 is the scheme large international retailers actually accept — because it is the only one of the three recognised by GFSI.
Choosing wrongly is expensive. Kenyan processors regularly certify to ISO 22000, then discover their target buyer requires GFSI-benchmarked certification and the work must be extended. This guide is built to prevent that — a decision tool rather than another explanation of each standard.
If you want the depth on any one of them, we have full guides on HACCP, ISO 22000 and FSSC 22000. This article is about choosing between them.

🎯 The One Question That Decides It
“Which certification does my buyer contractually require?”
Not which is best. Not which is most respected. Which one does the organisation paying you actually demand? Ask them in writing, before you spend a shilling. Everything below only helps you interpret their answer.

The Side-by-Side Comparison
| HACCP | ISO 22000 | FSSC 22000 | |
|---|---|---|---|
| What it is | A hazard-control methodology | A management system standard | A certification scheme |
| Built on | Codex Alimentarius, 7 principles | HACCP + PRPs + management system | ISO 22000 + sector PRPs + additional requirements |
| GFSI recognised | ❌ No | ❌ No | ✅ Yes |
| Typically required by | EU & US market entry (Reg 852/2004) | Regional, EAC & institutional buyers | Large international retailers & brands |
| Relative effort | Lowest | Moderate | Highest |
| Unannounced audit | No | No | ✅ One per 3-year cycle |
| Best if… | You’re starting out or need the baseline | You want a genuine management system | Your buyer says “GFSI” |
Find Your Situation
Choose By Your Buyer
“I need to get my product into the EU or US at all.”
→ HACCP. It is mandatory under EU Regulation 852/2004 and embedded in US federal food safety rules. This is market entry, not competitive advantage.
“My buyer is a large international retailer or branded food company.”
→ FSSC 22000. They will almost certainly require GFSI-benchmarked certification. Neither HACCP nor ISO 22000 will satisfy that requirement.
“I supply Kenyan supermarkets, institutions, or EAC markets.”
→ HACCP, then ISO 22000 if you want a system that scales. GFSI recognition is usually not demanded at this level, so paying for FSSC 22000 may be premature.
“I don’t have a specific buyer yet.”
→ Start with HACCP and build the prerequisite foundations properly. Do not buy the most expensive certification speculatively — get a buyer, learn their requirement, then certify to it.

All three fail on the same thing
Whichever standard you choose, documentation is where audits are won or lost. Our free guide covers the 25 gaps that most commonly fail Kenyan audits.
The Fault Line
The GFSI Dividing Line
Almost every costly mistake in this area comes down to one misunderstanding, so state it plainly: the Global Food Safety Initiative recognises FSSC 22000. It does not recognise HACCP or ISO 22000 certification on their own.
That is not a judgement about quality — ISO 22000 is a rigorous international standard. It is a fact about what large retailers accept. When a buyer specifies “GFSI-benchmarked” or “GFSI-recognised,” they are excluding ISO 22000 whether they say so or not.
The useful consequence: FSSC 22000 is built on ISO 22000. So if you certify to ISO 22000 first and later need GFSI recognition, the foundation carries forward — KEBS notes that ISO 22000-certified operators can transition to FSSC 22000 relatively smoothly. It is a detour, not wasted work.
Common Ground
What All Three Share
- The same root. All three trace back to the Codex Alimentarius General Principles of Food Hygiene. Hazard analysis and critical control points sit inside every one of them.
- The same foundation requirement. Prerequisite programmes — cleaning, pest control, maintenance, staff hygiene — must be working before any of them means anything. KEBS positions Good Manufacturing Practices as the layer everything else is built on.
- The same failure mode. Audits are lost on records, not practice. Undated logs, missing verification, corrective actions taken but never documented.
- The same non-substitution rule. None of them replaces regulatory requirements — a KEPHIS phytosanitary certificate is still required for export regardless of which you hold.
Sequencing
Why the Order Matters
These are not three competing products. They are three rungs, and each one carries into the next:
GMP / prerequisites
↓
HACCP — hazard analysis & CCPs
↓
ISO 22000 — the management system
↓
FSSC 22000 — GFSI recognition
Build in this order and nothing is wasted: your hazard analysis, monitoring records, corrective-action procedures and prerequisite programmes all transfer upward. Skip rungs and you will usually end up building them anyway, under audit pressure, at higher cost.
Avoid These
Five Costly Mistakes
- Certifying to ISO 22000 when the buyer needs GFSI. The most expensive error in this article — and the most common.
- Treating HACCP as a certificate rather than a working system. A plan in a folder that nobody operates fails every audit, at every level.
- Skipping the prerequisite foundations. Hazard analysis on top of poor hygiene control is analysis of the wrong problem.
- Assuming certification replaces regulatory approval. It does not. Phytosanitary and licensing requirements apply regardless.
- Building documentation for audit day. Auditors check whether records were generated as work happened. Retrospective paperwork is visible and it is fatal.
Still not sure which one you need?
We help processors and exporters match the standard to what their buyers actually require — then build the system and prepare for the audit, so you certify once rather than twice.
Quick Answers
Frequently Asked Questions
What’s the main difference between the three?
HACCP is a hazard-control methodology. ISO 22000 is a full food safety management system standard including HACCP principles plus management, communication and improvement requirements. FSSC 22000 is a certification scheme built on ISO 22000 plus sector-specific prerequisite programmes and additional requirements — and it is the only one of the three recognised by GFSI.
Which do EU and US buyers require?
For market entry, HACCP-aligned systems are effectively mandatory — required under EU Regulation 852/2004 and embedded in US federal food safety regulation. Large international retailers typically go further and require GFSI-benchmarked certification, which means FSSC 22000. Always confirm the specific requirement with your buyer in writing.
Should I get ISO 22000 or FSSC 22000?
It depends on your buyer. If they require GFSI-benchmarked certification, ISO 22000 alone will not satisfy them. If you supply regional, EAC or domestic institutional buyers who value an international management system without demanding GFSI, ISO 22000 is appropriate and less demanding. Since FSSC 22000 is built on ISO 22000, work done for ISO 22000 carries forward if you upgrade later.
Can I skip HACCP and go straight to FSSC 22000?
You cannot skip the substance of HACCP, because both ISO 22000 and FSSC 22000 incorporate HACCP principles. What you can skip is a separate standalone HACCP certificate. Whether that makes sense depends on your starting point — organisations with weak prerequisite programmes usually benefit from building that foundation first.
Key Takeaways
- Ask your buyer first, in writing. Their requirement is the only answer that matters.
- Only FSSC 22000 is GFSI-recognised — that single fact decides most cases.
- HACCP is market entry for the EU and US, not competitive advantage.
- Build in order — GMP → HACCP → ISO 22000 → FSSC 22000. Nothing is wasted.
- All three fail on documentation, not on farming or processing practice.
