Buyer–supplier relationship's influence on traceability implementation in the vegetable industry

The increasing importance of food safety has made traceability a crucial issue in the agri-business industry. In this article, we have analysed the factors that shape buyer–supplier relationships, and how they influence the traceability of raw materials. In order to do so, first, we have reviewed the literature to develop an analytical framework. Next, we have carried out four case studies on vegetable firms with the purpose of uncovering the variables that characterise buyer–supplier relationships, and their influence on traceability in this sector. Finally, we have compared the observed links with the conceptual framework derived from the literature in order to build an improved model.
