Products from genetically modified crops can be identified at low concentration

It is important to be able to monitor genetically modified (GM) crops, not only in the field but also during the food processing chain. New research published in BioMed Central‘s open access journal BMC Biotechnology shows that products from genetically modified crops can be identified at low concentration, using bioluminescent real time reporter (BART) technology and loop mediated isothermal amplification (LAMP). The combination of these techniques was able to recognise 0.1% GM contamination of maize, far below the current EU limit of 0.9%.

In agriculture GM crops have been bred to improve crop yield or viability. For example some are resistant to herbicides or viruses. They are also used in the pharmaceutical industry to produce proteins such as collagen. However there is a constant debate about the safety of these crops and whether the human-made transgenes might enter the wild population by cross-fertilization.and produce herbicide resistant weeds.

Careful handling and sampling techniques are required to assess the GM content of a crop.
