What key document outlines the requirements for food safety management systems?

The key document that outlines the requirements for food safety management systems is ISO 22000. This standard provides a comprehensive framework for managing food safety throughout the food supply chain. It integrates elements of good manufacturing practices, hazard analysis, and critical control points (HACCP) principles, ensuring that organizations effectively control food safety hazards.

ISO 22000 is specifically designed to ensure that food is safe for consumption, addressing the specific needs of the food industry. This includes requirements for developing, implementing, and maintaining a food safety management system, as well as continuous improvement based on performance monitoring.

The other standards mentioned serve different purposes: ISO 9001 is focused on quality management systems, ISO 14001 is about environmental management, and ISO 45001 pertains to occupational health and safety management. While each of these contributes to their respective areas within organizational management, none specifically addresses food safety like ISO 22000 does.
