An imported rice product has been withdrawn from sale, after it was found to have trace quantities of an unauthorised genetically modified (GM) rice variety. New Zealand Food Safety Authority (NZFSA) ensured the withdrawal after tests showed traces of (GM) rice variety, Bt63, in "rice vermicelli" from China. NZFSA was not aware of health concerns from eating the product, it said. "However, Bt63 is not approved for sale in food in New Zealand as it has not had a Food Standards Australia New Zealand (FSANZ) safety assessment."
