Safety Assessment of Transgenic Organisms in the Environment, Volume 6

OECD Consensus Documents

image of Safety Assessment of Transgenic Organisms in the Environment, Volume 6

This series represents a compilation of the biosafety consensus documents developed by the OECD Working Group on Harmonisation of Regulatory Oversight in Biotechnology over the periods 2011-12 (Volume 5) and 2013-15 (Volume 6). Volumes 5 and 6 describe the biology, centres of origin, genetics, hybridisation, production and use, and ecology elements of several crops (sugarcane, cassava, sorghum, common bean, cucurbits) and trees (eucalyptus species). They also provide considerations on pathogenicity factors in assessing the potential adverse health effects of bacteria, and the low level presence of transgenic plants in seed and grain commodities.

The consensus documents contain information for use during the regulatory assessment of products of modern biotechnology, i.e. transgenic organisms (plants, animals, micro-organisms), when intended for release in the environment. As such, it should be of value to applicants for use of genetically-engineered organisms in agriculture mainly, to regulators and risk assessors in national authorities for their biosafety assessments, as well as the wider scientific community. More information on this OECD programme is found at BioTrack online (www.oecd.org/biotrack).




Low-level presence of transgenic plants in seed and grain commodities

Environmental risk/safety assessment and availability and use of information

This chapter provides guidance and information on the environmental risk/safety assessment of low-level presence (LLP) situations. LLP relates to seed containing small amounts of transgenic material that have been authorised for cultivation in an exporting country, but not in the country of import. It covers agricultural seed used for planting, and commodities (e.g. grains and oilseeds) that can grow into plants when unintentionally released in the environment or used for cropping. This chapter discusses the availability and the use of information when facing LLP situations: LLP occurrences in seed, national systems dealing with them, principles for determining environmental risk/safety for transgenic plants, data and information available to perform such an assessment, with examples of scenarios. Approaches to the management of LLP situations and possible ways to proactively address their environmental safety are considered.
