ISO 22000 is quickly growing in popularity. A hybrid of the ISO 9001 Quality Management System and the HACCP Food Safety system, 22000 has been developed as an international solution for improving food safety.
HACCP is based on seven principles: 1  Conduct a Hazard Analysis. 2  Identify the Critical Control Points. 3  Establish a maximum or minimum limit for temperature, time, pH, salt level, chlorine level or other processing characteristic that will control the hazard. 4  Establish Critical Limits. 5  Establish Monitoring Procedures. 6  Establish Corrective Actions.
