Genetically modified foods
Genetically modified (GM) foods are foods derived
from organisms whose genetic material (DNA) has been
modified in a way that does not occur naturally, e.g. through
the introduction of a gene from a different organism.
Currently available GM foods stem mostly from plants, but
in the future foods derived from GM microorganisms or
GM animals are likely to be introduced on the market. Most
existing genetically modified crops have been developed
to improve yield, through the introduction of resistance to
plant diseases or of increased tolerance of herbicides.
In the future, genetic modification could be aimed at
altering the nutrient content of food, reducing its allergenic
potential, or improving the efficiency of food production
systems. All GM foods should be assessed before being
allowed on the market. FAO/WHO Codex guidelines exist
for risk analysis of GM food.
