Accurate labelling of GMOs requires an extensive identity preservation system in the food supply chain from farmers to retailers (Maltsbarger and Kalaitzandonakes, 2000). It is also found that either testing or detailed record-keeping of traceable GM ingredients in food supply chain are needed at various steps in some GM-sensitive countries. Estimated costs of mandatory labelling vary from a 1-2 dollars per person per year up to 10% of a consumer’s annual food bill (Gruere and Rao, 2007). Caswell (1999) demonstrated a significant influence of labelling preference over the initial direction and speed of market development for foods produced by using GMOs. In support of his argument he mentioned that segregation difficulties, elevated marketing cost due to segregation and setting limits for disclosable amount of GM ingredients in food label are the key economic reasons to avoid mandatory labelling.
