Application of fault tree analysis: Failure mode and effect analysis to evaluate critical factors influencing non‐GM segregation in the US grain and feed supply chain

Background and Objective Adventitious presence (AP) or unintentional commingling of genetically modified (GM) grain in non-GM lots is a concern for stakeholders who wish to produce grain-based products. AP that exceeds tolerance levels results the loss product marketability as “non-GM” subsequent premium market price. The objective this study was evaluate US commodity corn supply chain using Fault Tree Analysis (FTA) Failure Mode Effect (FMEA) assess factors contributing chains handle both GM Findings Systematic analysis farm-to-feed identified key processes actors involved. FTA 27 potentially along with their root causes. Ranking FMEA prioritized 14 “critical” comparatively higher likelihood occurrence impact on levels. Conclusions were found across chain, indicating successful segregation relies all participants. Identification prioritization critical make it possible target resources small number significant attain low rather than distributing entire set factors. Significance Novelty This an initial attempt provide insights into assessment management feed novel application techniques.
