The term bioengineered foods refers to foods produced using Genetic Modification (or GM). We currently don't produce any GM foods in Australia, and any imported foods with GM sold here must be pre-approved before they are sold to ensure safety. Any GM foods must also be labelled so you can make an informed choice. Genetic Modification is a way of fast-tracking the creation of a desired characteristic in a crop. In the past it took a long time to create changes through selective breeding whereas now GM technology allows plant scientitists to change the DNA, or genetic blueprint, of a plant to creat the desired trait straight away. For example, common GM plants are resistant to particular pests or herbicides. GM also offers a means to nutritionally improve food crops as well, such as rice with increased levels of vitamin A. There is a lot of controversy about GM foods and most of the information out there is negative and not a good representation of the science (but rather driven by emotion, ethics, ideology, fear and misunderstanding). There are positives and negatives to GM foods, but lack of safety is not well supported by the science.
You can read more about GM food in my book Food Myths (New Holland) or check out the Food Standards Australia and New Zealand fact sheet at http://www.foodstandards.gov.au/consumerinformation/gmfoods/
