Two Paths to Food Safety Certification
If you are in the food industry and exploring food safety certification options, you have almost certainly come across both ISO 22000 and SQF. They both deal with food safety management. They both require audits. And they both carry real weight with buyers and retailers. But they are not the same thing, and choosing the wrong one for your business can cost you time, money, and the very contracts you were trying to win.

This article breaks down the difference between ISO 22000 and SQF certification in plain terms. We will cover what each standard actually requires, who recognises each one, which industries tend to prefer each, and how to figure out which one makes sense for your specific situation.
What Is ISO 22000?
ISO 22000 is an international standard for food safety management systems, published by the International Organization for Standardization. It provides a framework for any organisation in the food chain to identify and control food safety hazards. That includes farms, processors, manufacturers, packaging companies, transport and storage operators, and even equipment suppliers.
The standard is built around two core concepts: HACCP (Hazard Analysis and Critical Control Points) and prerequisite programmes. It follows the same high-level structure as other ISO management system standards like ISO 9001 and ISO 14001, which means it integrates well if you already hold or are pursuing other ISO certifications. You can read more about ISO 22000 in detail in our essential guide to safe and reliable food production.
ISO 22000 is a genuinely global standard. It is recognised in over 180 countries and is published in multiple languages. If your business operates internationally or exports to markets across Europe, Asia, the Middle East, or Latin America, ISO 22000 carries strong recognition with buyers and regulators in those regions.
What Does ISO 22000 Actually Require?
ISO 22000 requires your business to establish, implement, maintain, and continually improve a food safety management system. The key elements include:
- Context of the organisation: Understanding your internal and external environment, including interested parties and the scope of your food safety system
- Leadership commitment: Top management must actively support and be accountable for the food safety system
- Risk-based thinking: Identifying risks and opportunities that could affect food safety outcomes
- Hazard analysis: A systematic process to identify biological, chemical, and physical hazards at every step of your operation
- Operational prerequisite programmes (OPRPs): Controls for hazards that are not managed through critical control points but still need to be addressed
- HACCP plan: A documented plan covering critical control points, critical limits, monitoring procedures, and corrective actions
- Traceability: The ability to trace products through the supply chain, which connects closely with ISO 22005 traceability requirements
- Internal audits and management review: Regular checks to ensure the system is working and improving
Certification to ISO 22000 is granted by accredited third-party certification bodies. The audit process typically involves a Stage 1 documentation review followed by a Stage 2 on-site audit. Surveillance audits happen annually, with full recertification every three years.
What Is SQF Certification?
SQF stands for Safe Quality Food. It is a food safety and quality management programme owned and managed by the Safe Quality Food Institute (SQFI), which is a division of the Food Marketing Institute (FMI) based in the United States. SQF is recognised by the Global Food Safety Initiative (GFSI), which is the benchmark that most major retailers and food service companies around the world now require from their suppliers.
Unlike ISO 22000, which is a single standard, SQF is a programme with a code that is updated periodically. The current version is SQF Code Edition 9. The programme covers a wide range of food sectors and includes specific modules for primary production, food manufacturing, food packaging, distribution, and retail.
The Three Levels of SQF Certification
One of the features that makes SQF distinct is its tiered certification structure. There are three levels:
- SQF Level 1 (Food Safety Fundamentals): This is the entry level, focused on basic food safety controls. It is designed for lower-risk operations or businesses that are just beginning to formalise their food safety practices. It is not GFSI recognised at this level.
- SQF Level 2 (HACCP-based Food Safety Plans): This is the most commonly pursued level. It requires a full HACCP-based food safety plan and is GFSI benchmarked. Most retailers and food service buyers who require GFSI certification will accept Level 2.
- SQF Level 3 (Comprehensive Food Safety and Quality Management System): This level adds a quality management layer on top of the food safety requirements. It is suited to businesses that want to demonstrate both food safety and quality to their customers.
SQF audits are conducted by licensed SQF auditors who are registered with SQFI. The audits are unannounced in some sectors, which is worth knowing before you pursue this route.
ISO 22000 vs SQF: The Key Differences
Now that you understand what each one is, here is where they actually differ in ways that matter to your business decision.
Geographic Recognition
ISO 22000 has broader international recognition. If you are exporting to Europe, the Middle East, or Asia, ISO 22000 is often the preferred or required certification. European retailers and food authorities are very familiar with it.
SQF is dominant in North America, particularly in the United States and Canada. If your primary market is supplying US grocery chains, foodservice distributors, or retailers, SQF is often what they specifically ask for. Many US retailers have SQF written into their supplier approval requirements.
GFSI Recognition
Both ISO 22000 and SQF Level 2 and Level 3 are GFSI benchmarked. This means that in theory, major retailers who require GFSI certification should accept either. In practice, some buyers have a preference or a specific requirement for one over the other. Always check with your actual customer what they will accept before committing to a certification path.
Scope and Flexibility
ISO 22000 is a single standard that applies broadly across the entire food chain. It does not have sector-specific modules built in, though it is often used alongside ISO/TS 22002 sector-specific prerequisite programmes (covering food manufacturing, catering, farming, and packaging).
SQF has sector-specific codes built directly into the programme. There are separate modules for primary production, food manufacturing, storage and distribution, retail, and food packaging. This means the SQF audit is more tailored to your specific sector from the start.
Quality vs Pure Food Safety
ISO 22000 focuses specifically on food safety. It does not include quality management requirements in the same way that ISO 9001 does. If you want both food safety and quality, you would typically implement ISO 22000 alongside ISO 9001, or consider an integrated management system.
SQF Level 3 includes quality management requirements within the same programme. So if your customers require both food safety and quality certification and they operate in North American markets, SQF Level 3 can cover both in a single audit.
Audit Style and Unannounced Audits
ISO 22000 audits follow the standard ISO certification audit process. Stage 1 and Stage 2 audits are scheduled in advance. Surveillance audits are typically announced.
SQF can include unannounced audits depending on your sector and the requirements of your customers. Some retailers specifically require that their suppliers undergo unannounced SQF audits. This changes how you need to maintain your system day to day. You cannot tidy things up the week before an audit. Your system has to be genuinely operational at all times.
Cost and Implementation Effort
Neither standard is cheap to implement properly. The costs depend heavily on the size of your operation, your current level of food safety maturity, and whether you use a consultant to help. If you are comparing quotes from consultants or certification bodies for either programme, the guide to comparing ISO certification quotes covers what to look for so you are not comparing apples with oranges.
Generally speaking, SQF can involve higher ongoing costs because of the SQFI licence fee that certification bodies must pay, and because the sector-specific requirements can be more prescriptive. ISO 22000 tends to have more flexibility in how you demonstrate compliance, which can reduce implementation effort if you have a capable consultant who knows the standard well.
Who Should Choose ISO 22000?
ISO 22000 tends to be the better fit if:
- You export or plan to export to international markets, particularly in Europe, the Middle East, or Asia Pacific
- Your business already holds other ISO certifications and you want to integrate your management systems
- You operate somewhere in the food chain that is not food manufacturing, such as logistics, packaging, or equipment supply
- Your customers have not specified SQF and are comfortable with GFSI benchmarked certification generally
- You want a flexible, internationally recognised standard that a wide range of certification bodies can audit
A food manufacturer in Australia supplying to export markets in Asia and the Middle East, for example, would almost always be better served by ISO 22000 than SQF. The recognition is stronger in those markets and the pool of accredited certification bodies is larger.
Who Should Choose SQF?
SQF tends to be the better fit if:
- Your primary customers are US or Canadian retailers, grocery chains, or foodservice distributors who specifically require SQF
- You have received a direct request from a buyer to become SQF certified
- You want sector-specific requirements built into your audit rather than having to reference separate technical specifications
- You are pursuing Level 3 and want to combine food safety and quality management in a single programme
- You are already operating in a market where SQF is the dominant standard and switching would create friction with customers
A food manufacturer in the United States supplying private-label products to a major grocery chain would almost always need SQF, because that is what the retailer requires and what their supplier approval process is built around.
Can You Hold Both ISO 22000 and SQF?
Yes, and some businesses do. If you are supplying to both North American and international markets, holding both certifications removes any ambiguity about which standard a particular customer requires. The two systems are compatible enough that the documentation and operational controls largely overlap. You would not be building two completely separate systems from scratch.
That said, maintaining two certifications does mean two sets of audits, two sets of fees, and two sets of ongoing surveillance obligations. For most small to medium businesses, the cost of dual certification is hard to justify unless you have a clear commercial need for both. Be honest with yourself about whether your customer base actually requires it before going down that path.
A Note on FSSC 22000
If you are researching food safety certification, you will almost certainly come across FSSC 22000 as well. FSSC 22000 is a certification scheme built on top of ISO 22000, adding sector-specific prerequisite programmes and additional FSSC requirements. It is also GFSI benchmarked and is widely recognised by major global food manufacturers and retailers.
FSSC 22000 is often the preferred choice for food manufacturers who want ISO 22000 as the foundation but need the additional rigour and GFSI recognition that comes with the FSSC scheme. If your customers are large multinational food companies, FSSC 22000 may be what they specifically require rather than plain ISO 22000.
So in practice, the decision is sometimes not just ISO 22000 versus SQF, but ISO 22000 versus FSSC 22000 versus SQF. The right answer depends entirely on who your customers are and what they have written into their supplier requirements.
How to Make the Right Decision
Here is the most practical advice I can give you: before you spend a single dollar on implementation, contact your top three to five customers and ask them directly what food safety certification they require or prefer. Get it in writing. That one conversation will save you from months of wasted effort pursuing the wrong standard.
If your customers are split between markets, talk to a consultant who has genuine food industry experience. Not someone who knows ISO management systems generically, but someone who has worked in food manufacturing or food retail and understands how these standards are applied in practice. The difference in advice you will get is significant. Our article on why industry expertise matters when choosing an ISO consultant explains why this distinction is so important.
Also consider your longer-term growth plans. If you are a small Australian food manufacturer currently selling domestically but planning to export to the US in three years, it might be worth building toward SQF now rather than having to transition your system later. Conversely, if your export ambitions are focused on Asia and the Middle East, ISO 22000 or FSSC 22000 is the smarter long-term investment.
Getting Certified: What to Expect
Regardless of whether you choose ISO 22000 or SQF, the certification journey follows a similar pattern. You need to build or formalise your food safety management system, conduct a gap analysis against the standard, implement the required controls and documentation, run your system for a period to generate evidence, and then go through the certification audit.
For most food businesses starting from scratch, the implementation process takes somewhere between six and twelve months depending on the complexity of your operation and how much resource you can dedicate to it. Trying to rush it typically results in a failed audit or a system that passes on paper but does not actually function in practice. If you want a broader picture of what the certification journey looks like from start to finish, the first-time ISO certification guide covers the process in detail.
Getting the Right Help
Food safety certification is one of the areas where having the right consultant or certification body genuinely makes a difference. The standards are technical, the audits are rigorous, and the commercial stakes are high. A consultant who has actually worked in food manufacturing or food safety management will help you build a system that works, not just one that passes an audit.
