The document provides guidance for food manufacturers on integrating the requirements of the US Food Safety Modernization Act (FSMA) Preventive Controls for Human Food (PCHF) rule into an existing Food Safety System Certification (FSSC) 22000 system. It outlines key FSMA requirements in areas such as hazard analysis, food safety plans, supply chain controls and record keeping. The guidance is intended to help FSSC 22000 certified organizations demonstrate compliance with FSMA without needing separate food safety systems. Auditors must be trained on both FSSC 22000 and FSMA to conduct reviews using this guidance.
