Japan banned imports of Canadian wheat after it was discovered that some of the grain was genetically modified. The move has Canadian farmers worried because Canada is one of the world’s biggest wheat producers, selling about CAN$11 billion (US$8.3 billion) annually. Japan alone buys CAN$500 million (US$379 million) a year from Alberta province, where the genetically modified wheat was found. The situation came to light after the Canadian Food Inspection Agency (CFIA) made public that it had found a small amount of genetically modified wheat in Alberta. Other crops like corn have been genetically modified to attain better yields and are widely distributed, but GMO (genetically modified organism) wheat is not used in commercial production because of consumer concerns. It is banned in most countries.
