The term genetic
modification can be defined as a procedure that alters the DNA inside an
organism by the transfer of genes between the same, or different types of
organisms. These organisms do not have to be apart of the same biological
kingdom.

Genetically modified food
in particular occurs when an organism, which is to be consumed, consists of
altered DNA. An example of this is transfer of genes from a fish that lives in
a very cold climate to a strawberry. This strawberry is then resistant to
frost, thus the consumer is presented with fruit of a higher standard. Genetic
modifications like this may also occur between two animals or two plants
depending on the desired outcome for the product.

There are different
stages of genetic modification within food products, thus only a small section
of the product may in fact contain genetically modified genes. These stages are
as follows:
- Present in whole foods (e.g. corn, tomatoes)
- Present as ingredients in processed food (e.g. Soybean)
- Present in original food, yet absent after processing (e.g. cottonseed oil does not contain genetically modified material present in its original form, cotton plant)
- Present in early stage of food chain but not in final product (e.g. Beef from cows that have been fed genetically modified corn)

Ultimately, genetically modified food is any
product for consumption that contains altered characteristics in order to
create resistances to changes in the products environment (weather, habitat
etc.) and provide higher quality and more economical food to the public.
