ILSI IFBiC Workshop

Safety of GM crops: compositional analysis, Washington, DC, USA, 13–15 September 2012

The ILSI International Food Biotechnology Committee (IFBiC) hosted a workshop on September 13-15, 2012, in Washington, DC, to identify and address topics related to plant composition from a scientific perspective. The workshop brought together experts in plant breeding and crop composition from all over the world.

Fifteen invited speakers participated in four thematic sessions: conventional development of new crop varieties, development of crops using modern biotechnology, compositional analysis methods, and interpretation of composition data. In addition to these formal presentations, round table discussions were held involving all conference attendees to address four related topics: effects of transgenic versus conventional crop improvement methods on germplasm development, effect of natural variability in crop composition on data interpretation and safety evaluations, selection of comparators for compositional analysis as part of safety assessments, and design of compositional analyses/adequacy of existing OECD consensus guidelines.

Workshop Proceedings

The following documents are available for download in PDF format.


List of Participants


The fifteen invited speakers will each contribute a manuscript to be submitted for publication in a special issue of theJournal of Agricultural and Food Chemistry (JAFC). The keynote speakers will write an additional manuscript following the conference to summarize the discussions and highlight key points made by individual speakers. ILSI intends to purchase the copyrights for the JAFC special issue, so that all members of the scientific community will have open access to the sixteen papers produced by the conference speakers.
