A framework for the recursive risk-ranking of foodborne zoonotic threats along food supply chains

concept), we focus on foodstuffs as sources of pathogens because they directly lead to exposure through consumption. The framework allows iterative application of the evaluation model to prioritize threats and update these priorities as new evidence emerges, while also enabling refinement of the model as the decision context evolves. We assessed the framework at the German Federal Institute for Risk Assessment with encouraging results. We discuss our results and the potential benefits of such recursive assessments for managing supply-chain food risks and enhancing national and global food safety.
