The genetically modified linseed lines show an altered fatty acid composition in seeds towards very long-chain polyunsaturated fatty acids. No difference regarding persistence in agricultural habitats or invasiveness in natural habitats compared to conventional linseed is expected. Nor is it expected that a selective advantage or disadvantage is conferred to the GM lines via the introduced trait. Due to the measures to be taken during the release (distance to or absence of cultivated and wild relatives) and linseed as a self-pollinating crop is the potential for permanent gene transfer will be virtually excluded. Interactions of the GM linseed lines with non-target species and resulting effects will be comparable to those of conventional linseed varieties. The potential of altered fatty acid composition in seed resulting in any effects on animal health from contact or consumption is considered negligible. Measures in place under current field trials in relation to handling, harvest, storing, transport or disposition will further minimize the probability of any negative effects on health or environment. No effects are expected on biogeochemical processes from the predicted trait. The GM linseed lines will be cultivated under conventional agricultural practices.
