ISO 22000 or FSSC 22000: which certification to choose in 2026?

Your food business has decided to get its food safety management certified, and two acronyms keep coming up: ISO 22000 and FSSC 22000. The two share a common foundation — to the point that the second contains the first — but they do not serve exactly the same markets. Here is how to decide, without discovering after the audit that your customers expected the other certificate.

The common foundation: the ISO 22000 standard

ISO 22000, in the edition currently in force published in 2018, defines the requirements of a food safety management system: the Codex Alimentarius HACCP principles, prerequisite programmes (PRPs), and the continuous-improvement logic shared by the ISO management standards. It addresses the whole food chain and is certified by accredited bodies, over a three-year cycle with annual surveillance — details on our ISO 22000 certification page.

It is a demanding, internationally recognised certification. But it has one precise commercial limit: it is not recognised by the GFSI (Global Food Safety Initiative), the industry body whose recognised schemes most large retail chains require from their suppliers.

What FSSC 22000 adds

FSSC 22000 is a certification scheme that explicitly builds on ISO 22000 and completes it:

Brick	ISO 22000	FSSC 22000
Management system (the ISO 22000 standard)	Yes	Yes — in full
Standardised sector PRPs (ISO/TS 22002 series)	Recommended as support	Required by sector
Additional scheme requirements	—	Yes (topics such as food fraud and food defense)
GFSI recognition	No	Yes

Direct consequence: a company certified against FSSC 22000 applies all of ISO 22000, plus complementary requirements. The upgrade path runs in one direction only, and none of the work is ever lost.

Choose by your markets, not by brand awareness

The right question is not “which certification is best?” but “who will read my certificate?”.

• Your customers are manufacturers, wholesalers, contract caterers, or you target exports: ISO 22000 generally meets the need — it provides third-party evidence of organised, managed food safety, in an international language.
• You target retail listing, especially under private label: you need a GFSI-recognised scheme. FSSC 22000 is the natural choice if your culture is already “ISO”; IFS and BRCGS are the historical alternatives, requested depending on retailers and regions. Our dedicated page compares that family of GFSI-recognised schemes.
• You are not ready for either yet: start with the foundation — a solid PMS (the French sanitary control plan), a living HACCP, then the management system. Our guide to getting ISO 22000 certified details this progressive trajectory.

A word on what “certificate” means to your customers: the scheme’s value rests on the rigour of the third-party audit. The work of Friederike Albersmeier, Holger Schulze, Gabriele Jahn and Achim Spiller, published in 2009 in Food Control, analysed the reliability of certification systems in the food chain and argues for risk-oriented audits rather than mere checklist verification (see the study). That is exactly what buyers look for: a genuinely lived system, not a compliant binder. Whatever scheme you choose, the maturity of your system is what gives your certificate its value.

What stays the same across schemes

Whichever option you pick, several invariants structure the project — worth factoring in from the start:

• the regulatory baseline: the EU hygiene package, HACCP procedures and the sanitary control plan remain mandatory and state-enforced, certificate or not — see our HACCP and PMS page;
• third-party accredited certification: in both cases the certificate is issued by an accredited certification body after an on-site audit;
• the certificate’s life cycle: initial audit, periodic surveillance, renewal — a long-term commitment, not a one-off project;
• the internal workload: a living hazard analysis, kept records, internal audits, management review. The same engine runs under both bonnets.

In other words, the bulk of the investment — building a genuinely managed food safety system — is common. The choice of scheme mostly decides the commercial recognition of the result.

The practical decision criteria

1. The contractual requirement. Re-read the specifications: if a customer demands “a GFSI-recognised scheme”, ISO 22000 alone will not do — clarify before committing to any audit. The exact status of each requirement is covered in our article Is ISO 22000 mandatory?
2. Your maturity. FSSC 22000 assumes PRPs at the level of the ISO/TS 22002 specification for your sector and the additional requirements covered: if the gap is wide, an intermediate step through ISO 22000 can secure the trajectory.
3. The budget over the cycle. Both schemes follow a three-year cycle with annual surveillance; compare quotes over the full cycle and on an identical scope.
4. Group consistency. If other sites in the group are already certified against one scheme, harmonising simplifies audits and documentation.

Take action

Start by mapping your customers’ actual requirements, then measure your gap to the foundation: the ISO 22000 certification page — process, cycle, frequently asked questions, free ebook — gives you the working base. The ISO 22000 foundation is never a detour: it underpins every trajectory, including the one towards GFSI recognition.
