ISO 22000 is an international accredited standard that harmonizes existing international and industry certification schemes and incorporates HACCP principles, though HACCP can still be implemented as a separate risk management tool. ISO 22000 creates an effective and common structure for food safety management, communication throughout the supply chain, and management of food safety critical control points.
ISO 22000 integrates the principles of the Hazard Analysis and Critical Control Point (HACCP) system and application steps developed by the Codex Alimentarius Commission. Hazard analysis is the key to an effective food safety management system, since conducting a hazard analysis assists in organizing the knowledge required to establish an effective combination of control measures. ISO 22000 requires that all hazards that may be reasonably expected to occur in the food chain, including hazards that may be associated with the type of processes and facilities used, are identified and assessed. Thus, it provides the means to determine and document why certain identified hazards need to be controlled by a particular organization and why others need not.
