HACCP has evolved over the years, and so has ASQ. As a result of this evolution, the ASQ Certified HACCP Auditor examination has also evolved. It first started as an add-on certification to the Certified Quality Auditor; then in 2004, the ASQ Certification Board approved it as a stand-alone certification. Along with this change, the Body of Knowledge was updated to include the principles of management systems auditing and the analytical tools of quality assurance.
As a result, this new handbook was developed to assist the certification candidate to prepare for the CHA examination. This volume incorporates most of the resource material that was first published in the book The Quality Auditor's HACCP Handbook, and includes brand new chapters covering the HACCP audit, the HACCP auditor, and quality assurance analytical tools. In addition, new appendices describe ISO 22000:2005, Food safety management systems - Requirements for any organization in the food chain, and also validation of HACCP systems.
