- Fertile genetically modified plant material has to be stored in closed and clearly labelled repositories for transport and storage at any time outside the release site and laboratory. On the labels it needs to be noted that these potatoes are unfit for consumption. Remaining potato tubers have to be disposed by chopping, squeezing or autoclaving.
- To prevent entering of the release site by wild animals (including rabbits) a fence has to surround the release site.
- Inspection of the release site on unexpected biological traits of the LMO and reciprocal effects between LMO and other organism has to be accomplished weekly during the experimental release and monthly after the experimental release.
- Monthly inspection of the surrounding area [20 m] of the release site for transgenic potato volunteers and their removal and disposal.
- After completion of the field trial the soil needs to be loosen up to uncover remaining potato tubers in the field site which have to be removed and disposed.
- Machines that have been in contact with LMOs have to be cleaned after use.
- After completion of the field trial an inspection of the release site and the surrounding area for transgenic potato volunteers, their documentation and removal and disposal has to be accomplished monthly for one year. if volunteers were observed the inspection period has to be extended for another year. Thereby the release site must not be cultivated with plants impairing the detection of transgenic volunteers.
