Spilled GM canola growing in Japan - Citizens' survey results 2007. English Repo

The Japanese Ministry of the Environment and the National Institute for Environmental Studies (NIES) have been continuing to conduct surveys of oilseed rape (canola) populations around Japanese ports.

On July 7, 2007, NO! GMO Campaign published the findings of a survey of spilled GM canola found growing in Japan. The survey was carried out from March 2007 onwards by citizens in 43 out of the total of 47 prefectures in Japan. In total, 1617 samples were tested and of these 37 showed up as GMO positive. A similar survey was also conducted in South Korea.

The samples were collected not only around ports where canola (oilseed rape) is imported, and around factories where canola oil is extracted, as well as along canola transportation routes, but also in some urban areas and on farmland.

Oilseed rape is not cultivated much in Japan, so Japan mostly imports it from Canada and Australia. 80% of the canola imports come from Canada, and are presumably GM. Non-GM canola is imported from Australia.
