FSSC 22000 (Food Safety System Certification) and ISO 22000 (Food Safety Management Systems) are both international standards for food safety management. However, there are some key differences between the two:
 
Certification Body: FSSC 22000 certification is issued by third-party certification bodies, while ISO 22000 certification can be self-declared or issued by a third-party certification body.
 
Scope: FSSC 22000 is specifically designed for food manufacturers and covers the entire food supply chain, while ISO 22000 certification can be applied to all organizations involved in the food chain, including feed producers, primary producers, food manufacturers, transport and storage operators, and retailers.
 
Additional Requirements: FSSC 22000 includes additional requirements for prerequisite programs (PRPs) and food safety plans (HACCP), while ISO 22000 only requires the implementation of a HACCP-based food safety management system.
 
Recognition: FSSC 22000 is recognized by the Global Food Safety Initiative (GFSI), which means it is accepted by many retailers and food service companies worldwide. ISO 22000 is not GFSI-recognized, but it is widely recognized and accepted in many countries.
 
In summary, FSSC 22000 is a more comprehensive and rigorous standard that is specifically designed for food manufacturers and recognized by the GFSI, while ISO 22000 is a more general standard that can be applied to all organizations involved in the food chain.
