1.When Food Safety Becomes Personal
The call comes late on a Friday afternoon. A retailer pulled your product from shelves in three states. A customer reported finding something in their food that should not have been there. The retailer wants answers. They want to know your lot codes, your distribution records, and your investigation findings by Monday morning.
You pull your production records. The lot in question ran two weeks ago. You trace the ingredients back to their suppliers. You review your sanitation records and inspection logs. Everything looks normal. But somewhere, somehow, something went wrong.
2.What is ISO 22000?
ISO 22000 is the international standard for food safety management systems. It provides a framework for organizations across the food chain to demonstrate their ability to control food safety hazards and consistently provide safe products.
ISO 22000 integrates principles from Codex Alimentarius HACCP guidelines with ISO management system structure. It combines the systematic hazard analysis approach that food safety professionals know with the management framework that drives organizational commitment.

3.The Foundation: Prerequisite Programs
Before you can manage specific food safety hazards, you need basic conditions and activities that maintain a hygienic environment. ISO 22000 calls these prerequisite programs, or PRPs. They form the foundation on which effective HACCP plans build.
Common Prerequisite Programs
- Facility construction and layout
- Equipment design and maintenance
- Pest control
- Cleaning and sanitation
- Personnel hygiene
- Supplier control
- Allergen management
- Storage and distribution
4.Hazard Analysis and Critical Control Points
HACCP provides the systematic approach to identifying and controlling food safety hazards. ISO 22000 incorporates HACCP principles while integrating them into the broader management system framework.
1Hazard Analysis
Identify all food safety hazards that could reasonably be expected to occur - biological hazards like pathogens, chemical hazards like allergens and toxins, and physical hazards like foreign materials. Evaluate likelihood and severity for each.
2Control Measures
For each significant hazard, identify control measures that prevent, eliminate, or reduce the hazard. These might be PRPs, operational PRPs (OPRPs), or critical control points depending on their role.
3Critical Control Points
CCPs are steps where control is essential. For each CCP, establish critical limits, monitoring procedures, corrective actions, and verification activities.
4OPRPs
Operational prerequisite programs are control measures identified as essential but not managed as CCPs. They require monitoring and corrective actions but may not need the same critical limits as CCPs.
5.Traceability and Recall
ISO 22000 requires traceability systems that identify product lots and their relationship to raw material batches and delivery records. When problems occur, you must be able to trace forward to affected products and trace backward to ingredient sources.
Traceability Requirements
- Link product lots to raw material batches
- Link lots to delivery records
- Enable trace forward to affected products
- Enable trace backward to ingredient sources
- Establish and test withdrawal/recall procedures
- Consider post-delivery activities affecting food safety
