ISO 22000 is an international food safety management standard that was published in 2005 and revised in 2018. It outlines requirements for organizations to develop and implement a food safety management system to ensure safety throughout the entire food supply chain. The standard was developed in response to several food crises and the need for harmonization. ISO 22000 can be applied by organizations of any size in the food industry. It incorporates key elements like hazard analysis, prerequisite programs, and HACCP principles. The revision in 2018 aimed to better align an organization's strategic direction with its food safety management system.
