Implementation of a traceability system in the bulk grain supply chain is a complex task. Grain lots are often commingled to meet buyer specifications and the lot-identity is not maintained. In this paper, a systems approach is used to develop methods for implementing bulk grain supply chain traceability in the United States, that includes both internal and chain traceability. First, the usage requirements of a traceability system are defined for all the actors in the supply chain. Second, a model is developed for implementing internal traceability system for a grain elevator that handles specialty grain. Then, we develop a model for information exchange between the supply chain actors. The model shows what grain lot information must be recorded and then passed on to the next actor. A sequence diagram is developed to show the information exchange in the grain supply chain when a user requests additional information about a suspect product. Finally, we discuss some suitable technologies to enable this information exchange. A few sample XML documents are shown for the transfer and sharing of information in the grain supply chain.
