One Health Perspectives on Food System Transformation: Insights from the InsectERA Agenda

Abstract Background One Health framework recognises the interconnectedness of human, animal, plant and environmental health. With this understanding, it becomes imperative to address challenges such as those posed by food systems through a One Health lens. Food systems pose significant public health challenges, particularly in terms of food safety and security. Pressures from factors such as population growth, changing consumption patterns and intensified production systems, particularly animal-based protein production, contribute to environmental pressures. In addition, environmental changes, including climate change, further threaten food safety and access to healthy food. Methods Through the InsectERA agenda, funded as part of the Recovery and Resilience Plan, stakeholders collaborated across sectors to explore the potential of insects as bioindustrial tools to address food system challenges. A structured, integrated approach combining health and sustainability considerations was matured and applied to pilot food products developed through this initiative. Recognising the potential health and sustainability impacts of these products, a comprehensive assessment was carried out. Results This study defined a structured, integrated approach to assessing the health and sustainability impacts of foods developed under the InsectERA agenda. Key steps included i) identifying critical issues and questions, ii) prioritising considerations, iii) defining methodologies, iv) collecting and analysing data, and v) integrating results for communication. Conclusions The study highlights the importance of integrated approaches in addressing food system transitions. Integrated approaches, guided by the One Health framework, play a critical role in informing policy decisions by providing policy makers with robust evidence. There is an urgent need for food system transformation based on decisions that holistically consider health and sustainability impacts, to ensure the protection of Public Health. Key messages • Integrating health and sustainability into the transition of food systems, within the One Health framework, is crucial for identifying options that safeguard Public Health. • A structured, integrated approach within a multi-stakeholder environment offers robust insights for policy decisions, advancing sustainable food systems.
