Why Is ISO 22000 Important?

The food industry operates in a high-risk environment. A single error in handling, storing, or processing can lead to serious health issues or even fatalities.

In short, ISO 22000 certification shows that your organization puts safety first and that’s a strong competitive advantage.

Key Components of a Food Safety Management System (FSMS)

An FSMS is a structured approach to identifying, controlling, and preventing food safety hazards in an organization. ISO 22000 provides a framework for building and managing an effective FSMS based on the Plan-Do-Check-Act (PDCA) model.

Main elements of FSMS under ISO 22000:

ISO 22000 and HACCP Integration

One of the strengths of ISO 22000 is its full integration with HACCP (Hazard Analysis and Critical Control Points) — a globally accepted method for food safety risk assessment.

ISO 22000 not only incorporates the seven principles of HACCP but also strengthens them by adding additional layers of system management, communication, and performance evaluation.

The integration provides:

By combining ISO 22000 with HACCP, your business can create a foolproof safety system that reduces risks and meets global expectations.

Who Needs ISO 22000 Certification?

Any organization directly or indirectly involved in the food supply chain can benefit from ISO 22000 certification. This includes:
