Why Are Buyers Asking for FSSC 22000 When You Already Have ISO 22000?

Many food manufacturers face a common situation: they already have ISO 22000 certification, but their customers ask for FSSC 22000 or another food safety certification recognised by the Global Food Safety Initiative (GFSI).

This can be confusing because ISO 22000 is an internationally recognised standard. However, there is an important difference between the two, and understanding it can help businesses avoid losing potential customers.

What IS isO 22000?

ISO 22000 is an international standard for food safety management systems. It helps organisations identify and control food safety risks through management processes, HACCP principles and prerequisite programmes.

It is a recognised and certifiable standard, but ISO 22000 certification alone does not provide GFSI recognition.

What does FSSC 22000 offers?

FSSC 22000 is a food safety certification scheme built on ISO 22000. It includes additional requirements to provide a more comprehensive approach to food safety.

It combines ISO 22000 with the relevant sector-specific prerequisite programme standards from the ISO 22002 series and additional requirements covering areas such as:

• Food defence and protection against intentional contamination

• Food fraud prevention

• Allergen management

• Environmental monitoring

FSSC 22000 is recognised by GFSI. This recognition is important because many large retailers and food manufacturers prefer suppliers certified under a GFSI-recognised scheme.

It allows buyers to accept certification under approved schemes instead of conducting separate food safety audits for every supplier.

Why Does This Matter for Your Business?

If your customers only require ISO 22000, your existing certification may be sufficient.

However, if you supply or plan to supply multinational retailers and large food manufacturers, they may require a GFSI-recognised certification scheme.

Common options include FSSC 22000, BRCGS, IFS and SQF.

In such cases, ISO 22000 alone may not meet the customer's supplier approval requirements. Discovering this late in the sales process can lead to delays, additional costs or missed business opportunities.

The Good News: You May Already Have a Strong Foundation

If your organisation already holds ISO 22000 certification, you have an established food safety management system that can serve as the foundation for FSSC 22000.

The main additional work usually involves implementing the relevant sector-specific prerequisite programme standard and meeting the scheme's additional requirements.

For example, ISO 22002-1 has traditionally been used for food manufacturing, while other sector-specific requirements apply to different activities. The applicable requirements depend on the organisation's operations and the version of the scheme being used.

Much of the effort involves reviewing and strengthening existing practices related to facility design, equipment, utilities, waste management, pest control, cleaning and personnel hygiene.

ISO 22000 requires organisations to establish prerequisite programmes, while the relevant ISO 22002 standards provide more detailed requirements for these programmes.

Therefore, moving to FSSC 22000 is not necessarily starting from scratch. It involves identifying and closing the gaps in your existing system.

What Should Your Organisation Do?

If you are choosing a certification for the first time: If your target market includes large retailers or multinational food companies, check their supplier requirements before deciding.

Choosing an appropriate GFSI-recognised scheme from the beginning may help you avoid the cost and effort of upgrading later.

If you already have ISO 22000: There is no immediate need to upgrade unless your customers, contracts or business plans require it. However, it is worth discussing your future target markets with your sales team.

Understanding which customers you want to serve over the next two years can help you decide whether FSSC 22000 should become a priority.

Final Takeaway

ISO 22000 provides a strong foundation for food safety management, while FSSC 22000 adds sector-specific and additional scheme requirements and offers GFSI recognition.

The right certification is not just about meeting a standard. It is about meeting customer expectations and creating opportunities to grow your business.
