- Discusses study on application of HACCP principle 1 by manufacturing HACCP teams.
- Identifies weaknesses in knowledge of and errors in hazard analysis practice.
- Key hazard analysis issues include errors applying structured risk evaluation tools.
- Identifies need for further detailed guidance in the application of HACCP principle 1.
- Debates application of risk evaluation tools in HACCP, identifying further work needs.

HACCP is a key element of modern food safety management practice such that design, implementation, control and management of HACCP systems are crucial to the production of safe food products. Whilst it is widely accepted that food companies should apply HACCP, understanding of the factors impacting successful HACCP application is limited and this knowledge is important to the delivery of systems that will control all relevant food safety hazards. HACCP principle 1, Conduct a Hazard Analysis, forms a central pillar of any HACCP plan since hazards need to be identified, analysed and understood before effective control measures can be specified. However limited guidance is available to HACCP teams on exactly how to approach the application of this principle. This paper discusses an investigation into the application of HACCP principle 1 by HACCP teams operating within manufacturing sites of a multinational food company. Using a combination of HACCP knowledge testing and HACCP plan assessment, the study identified weaknesses in knowledge of significant hazard identification and errors in the hazard analysis process, including errors in application of structured risk evaluation methods. Findings suggest that this is an area of difficulty for HACCP teams and that further detailed guidance in the application of this HACCP principle is urgently needed.
