[...] Watson is an €11 million 3-year project with 45 partners across 20 countries funded by the European Union’s (EU) research and innovation framework Horizon Europe. The main goal of Watson is to combat fraudulent practices in the food chain by integrating various digital technological solutions that can be applied effectively across multiple agri-food supply chains. The proposed framework will be tested in 7 agri-food supply chains across different European countries considering different operational procedures and diverse environments: cereal, dairy, fish, honey, meat, olive oil, and wine. To achieve this, numerous digital technologies and platforms, such as portable DNA-based devices, multi-sensor scanning devices, IoT platforms, blockchain platforms, mobile apps, and digital product passports, will be used at different supply chain stages to prevent food fraud. Additionally, an early warning system based on robust and explainable artificial intelligence will be established in this food fraud prevention framework. This project will emphasize the need to enhance fraud prevention systems and validate the solutions in specific agri-food chains. The project will also contribute to raising consumer awareness regarding food safety and fraud, ultimately leading to the adoption of healthier lifestyles and the development of sustainable food ecosystems. The aim is to improve the integrity, authenticity, and safety of the global food supply chain, protect consumers, and foster trust in the food industry.
