ISO 22000 integrates the principles of the Hazard Analysis and Critical Control Point (HACCP) system and application steps developed by the Codex Alimentarius Commission. It combines these principles with prerequisite programs (PRPs) and applies them across the entire food chain. This comprehensive approach helps organizations address food safety risks efficiently. ISO 22000 Internal Auditor Training covers all these aspects, ensuring that auditors can evaluate and enhance food safety management systems effectively.
