In this synthesis review, EatSafe evaluates the characteristics of successful food safety training interventions with the goal to inform EatSafe’s own interventions in Nigerian and Ethiopian traditional food markets. Previous EatSafe research has identified how food safety trainings have been developed as a standalone intervention or one component of a broader intervention package, seeking to increase the knowledge of consumers, vendors, and other food value chain actors. However, the characteristics that underlie intervention efficacy have yet to be explored in detail. Therefore,EatSafe assessed 16 food safety training approaches using a qualitative evaluation framework, or a list of behavioral theory-based research questions on training approach, audience, context, and training curricula. The following paragraphs summarize key results.
