Detection of GM food
In March 2000, the Codex Task Force on Foods Derived from Biotechnology
established a Working Group on Analytical Methods (WGAM).
The WGAM compiled a list of available analytical methods,
including those for the detection or identification of foods or food ingredients
derived from biotechnology, and indicated the performance criteria and status
of the validation of each method.In 2002, the Working Group introduced
this list to the Codex Committee on Methods of Analysis and Sampling (CCMAS)
for endorsement. CCMAS was informed that the presence of a genetically modified
organism or its derivatives could be detected through DNA sequences present
as a result of recombination, or through the protein coded by the inserted
gene.
In 2004, CCMAS discussed Criteria for the Methods for the Detection and Identification
of Foods Derived from Biotechnology. FAO and WHO, in collaboration with ILSI,
held a workshop to introduce the tools, information and experiences available
to test for protein/DNA from foods derived from modern biotechnology to CCMAS
delegates and other interested parties. Emphasis was placed on similarities
and differences among chemical analytical methods available, with particular
attention to how biological factors can affect measurement results. Current
efforts in methods development, standardization and validation, including those
within ISO, were also described. |
