There are worries that the hay from genetically modified canola may contain seeds that will escape and grow. A lack of rain has forced some farmers to cut their crops, instead of harvesting for oilseeds. Fodder dealers may purchase the hay and then sell it to farmers who are unaware where the product came from. Alex Schaap, general manager of biosecurity at the Tasmanian Department of Primary Industries, says he didn’t expect segregation issues in the first year of GM canola in NSW and Victoria.
