The Australia New Zealand Food Authority (ANZFA) and biotechnology ethics advocates are at blows over plans to launch new genetically modified foods in supermarkets without warning labels. ANZFA has approved genetically modified corn and canola oil, for use in breakfast cereals, bread, pastries and snack foods. The food undergoes distilling in the production, which destroys the DNA and releases the manufacturer and retailer from the obligation to label the end product as genetically modified.
