Traceabilit y is an integral requirement in the agri food sector especiall y due to the perishable nature of food and the potential for health risks through transmission of bacteria. There are various traceabilit y s y stems that allow companies to keep track of their products both upstream and downstream.Radio Frequenc y Identification (RFID) is one such technolog y that facilitates eas y and automatic data collection. With the prolif eration of traceabilit y s y stems using different technologies, it becomes imperative for these s y stems to be able to interact with one another and be integrated into the compan y 's existing information infrastructure. This work aims to review the current research in this field with special emphasis on RFID s y stems. We also seek to identif y future areas of research in this field.

His research interests include production, planning and control of manufacturing systems, application of lean principles, study of discrete-event systems and cost estimation for various manufacturing processes. Dale Masel, Ohio University Dale received his PhD in Industrial Engineering from Penn State University in 1998 and in that same year, joined the faculty of the Department of Industrial and Systems Engineering at Ohio University. He is currently an Associate Professor at Ohio University, with teaching interests in Facility Design, Material Handling, and Warehousing. In addition, he is actively involved in research to develop methodologies for estimating the manufacturing cost of parts in the design phase of the life cycle.
