Toxicity in GE maize approved for Australia

Genetically-engineered maize which has toxic effects on the kidney and liver of laboratory rats has been cleared for use as food for humans and animals. This maize has been authorised for markets in Australia as well as other countries.
Would you know if you are eating GE maize? In restaurants, for example? Would you know that you got sick from the maize oil used for cooking or in a salad dressing?
Meanwhile in Europe, organic farmers are trying to protect their regions from the damaging effects on farming caused by the introduction of GE crops. These include contamination by GE pollen and the effects on bees producing organic honey.
