Information on the current applications of blockchain in food systems and the potential applicability, uses, and limitations of blockchain for feed ingredients common to the swine industry was gathered from a multitude of sources. The information on applications representative of supply chain logistics for imported feed ingredients was evaluated and limitations of blockchain in tracing lots of packaged ingredients vs. ingredients in bulk transportation was assessed. Overall, blockchain application is a viable technology to ensure traceability of feed ingredients. Blockchain provides key benefits including transaction security, auditability, and transparency. However, these benefits are accompanied by costs including, most importantly, the need for all-in
participation and a value-driven incentive to participate that is shared across the supply chain. In addition, due to the bulk commodity nature of many feed ingredients common to the swine industry, traceability to individual manufacturer or producer through any technology becomes limited to the largest storage and/or transportation unit in the supply chain. Ingredients that move through the supply chain as discreetly packaged products, whether in kilogram packages or metric ton super sacks, have an easier entry into and more optimal traceability within blockchain technology. These concepts were modeled into a scenario for potential soybean shipments including where suppliers may verify the implementation of key preventive controls to decrease the risk of disease transmission via feed distribution.Swine Health Information Cente
