Application of failure mode and effect analysis (FMEA), cause and effect analysis and Pareto diagram in conjunction with HACCP to a potato chips manufacturing plant

Summary Failure mode and effect analysis (FMEA) model has been applied for the risk assessment of potato chips manufacturing. A tentative approach of FMEA application to the snacks industry was attempted in order to analyse the critical control points (CCPs) in the processing of potato chips. Preliminary hazard analysis was used to analyse and predict the occurring failure modes in a food chain system (potato processing and potato chips processing plant), based on the functions, characteristics and/or interactions of the ingredients or the processes, upon which the system depends. CCPs have been identified and implemented in the cause and effect diagram (also known as Ishikawa, tree diagram and fishbone diagram). Finally, Pareto diagrams were employed towards the optimisation potential of FMEA.
