Genetically modified (GM) wheat is expected to receive regulatory approval in Canada between 2003 and 2005. There may be a definitive portion of the supply chain for wheat set to realize the potential benefits of GM wheat. However, by September 2000, 18 countries and the EU, 21 food retailers, 29 food manufacturers and six restaurant chains around the world had announced intentions to introduce either mandatory or voluntary labelling requirements for genetically modified foods. Thus, to allow genetically modified varieties of crops to be grown in Canada, while maintaining access to export markets requesting labelling, crop segregation or identity preservation systems must be introduced. The primary objective of the study was to compare the private and regional costs of three potential segregation alternatives, all of which utilize the bulk commodity infrastructure already established in western Canada to handle the segregation of non-GM wheat. The systems that were examined included the designation of a high throughput terminal, the designation of multiple small wooden elevators and lastly, the segregation of GM and non-GM wheat within terminals. The three options were analyzed under various GM adoption rates and volumes of non-GM wheat being demanded under the assumption that the low-cost option would be dependant on the availability of non-GM wheat in the region, as well as the amount of product requiring segregation. A model was used that attempted to simulate the decision-making processes of producers in the region as well as methods used by the companies handling the segregation in their attempts to source the required amount of non-GM grain. The results of the model indicated that segregation within terminals was almost always the low-cost option. However, an analysis of the potential risk of contamination indicated that this option was most likely the least feasible option. An analysis of the remaining two options indicated that the low-cost option for the entire region would be to designate a high throughput terminal under any circumstances. The results of the study illustrate the importance of contamination risk when determining the low-cost segregation strategy. The results also illustrate that failing to include regional costs, including lost rail incentives and the inefficiencies of small elevators may lead to sub-optimal strategies.
