From March 2021 - What changes for S1 greenhouses with the new GenTSV (2019)?

The new GenTSV came into force in March. Over the next few months, you will be able to read a series here about the new regulations that must be observed. Corresponding series on laboratory and animal husbandry will also be published shortly. The new GenTSV contains more specific details in many areas. The clear format, already familiar from the Technical Rules (TRBA) on biological substances, is already recognizable in its structure. A clear focus was placed on preventing the release of GMOs from genetic engineering facilities. This may not be so easy and will certainly need to be rethought in some genetic engineering facilities. A look at the structural and technical safety measures: With regard to ventilation options, the old GenTSV stated that appropriate measures to prevent the release of GMOs were recommended. Appropriate measures (e.g., nets) are now necessary if there is a possibility that GMOs, possibly in the form of pollen, could leave the genetic engineering facility via insects or birds (I. a) No. 2 Annex 3 GenTSV (2019)). Greenhouses often already have the appropriate protection to prevent the unwanted entry of small animals and insects as pests. In the future, however, greater attention will be paid to the integrity of these protective measures, as they are now classified as "necessary." Furthermore, from now on, there must be an easily accessible washing facility for cleaning hands with disposable towels and disinfectant dispensers, which was previously not necessary for greenhouses operated as S1 genetic engineering facilities (I. a) No. 1 Annex 3 GenTSV (2019)). In concrete terms, this means that buildings that previously lacked washing facilities must be retrofitted accordingly. What hasn't changed? Furthermore, the floor in greenhouses can also consist of gravel or earth beds, and the walkways should be paved. A water collection system should be in place if there is a possibility of GMOs entering the runoff water.
