Genetically engineered crops (GM foods) began to be cultivated in the U.S.A. from 1994, and the present world-wide acreage planted is about 81 million hectares. The GM soybeans planted account for more than 56 percent of all soybeans in the world. Japanese probably consume a large amount of GM soybeans because 96 percent of the soybeans consumed are imported from several countries that cultivate GM soybeans. If processed foods are correctly labelled then the consumer can know whether GM soybeans are used but labelling is not always accurate. The object of our study is to promote truthful labelling and we chose to investigate tofu. Tofu samples were purchased from supermarkets, convenience stores and speciality stores in Tokyo, Kanagawa and Saitama prefectures. We detected recombinant DNA of soybeans in 14 of 42 tofu samples. From tofu produced from domestic soybeans, recombinant DNA was detected in 2 of 15 samples slightly.
