Food supply chains are complex and vulnerable to many factors (e.g. climate, economy and human behavior) having a direct and indirect effect on the development of food safety risks. A system approach is needed that takes all of these factors into account in its complex interactions and that makes use of the huge amount of available data. In such system approach, it is clear that big data technologies and tools such as artificial intelligence and machine learning are needed, including a safe and powerful infrastructure allowing handling of big data and ensuring interoperability.
The potential of Bayesian Networks (BNs) in system approach will be demonstrated and the impact of climate and use of agrichemicals on the safety of feed for dairy cows will be used as an example. Relevant data sources and models were transferred to the WUR High Performance Cluster (WUR-HPC) infrastructure and automatic data extraction and visualization in a dashboard was realized. Both the BN model and the RIKILT big data infrastructure on WUR-HPC will be demonstrated.
It is expected that in future, the food safety WUR-HPC infrastructure developed by RIKILT will pave the road towards the implementation of the lab to the sample approach for on-line, real-time data acquisition systems that can feed food safety models on a cloud-based e-infrastructure empowering risk assessors (industry and authorities) to perform timely intervention actions at the sample site.
