In this farm‐to‐fork trial, genetically engineered (GE) Bt sweet‐corn and Bt potatoes were grown side‐by‐side with conventional varieties in the 2000 growing season at a farm and market in Hillsburgh, Ontario, Canada. The Bt sweet‐corn required no insecticides. From an economic perspective, only the first planting had pest pressure high enough to warrant the higher seed cost of the GE variety. The sweet‐corn harvested throughout the trial was segregated and labeled, and direct consumer evaluation of purchasing preferences was conducted. Overall, the Bt sweet‐corn outsold the conventional sweet‐corn by a margin of 680 dozen (or 8,160 cobs) to 452.5 dozen (or 5,430 cobs). A limited number of intercept interviews were conducted after consumers made their purchasing decision. The majority of consumers interviewed said they were more concerned about pesticides than genetic engineering; however, taste and quality also had a strong influence on purchasing decisions.
