ISO 22000 is an international standard that specifies the requirements for a food safety management system (FSMS). It is designed to ensure that organizations in the food chain can consistently provide safe products and services. The standard integrates the principles of the Hazard Analysis and Critical Control Point (HACCP) system and application steps developed by the Codex Alimentarius Commission. It combines generally recognized key elements to ensure food safety along the food chain, including interactive communication, system management, and prerequisite programs.
