  • EFSA endeavours to develop networking and stronger cooperation with the Member States, and to strengthen its relationship with institutional partners (European Union and international) and stakeholders, as recommended by EFSA’s Management Board. In accordance with EFSA’s strategy for cooperating with Member States, the EFSA Scientific Network for Risk Assessment of GMOs (hereafter referred to as “the GMO Network”) was established in 2010. Since its inaugural meeting in November 2010, the GMO Network has met once per year.

    The overall goals of the GMO Network are to improve dialogue among members, build mutual understanding of risk assessment principles, enhance knowledge and confidence in the scientific assessments carried out in the EU, and increase the transparency of the process among Member States and EFSA. It aims to raise the level of harmonisation of the risk assessments developed in the EU.

    Currently 27 Member States and Norway are members of the GMO Network. Switzerland is invited to the GMO Network as observer. Each country was allowed to nominate two Member Organisations: one with competence in molecular characterisation and food-feed safety (MC/FF) and one with competence in environmental risk assessment (ERA). These Member Organisations have appointed in total over 60 selected scientific experts to attend the yearly meetings in the light of the topics on the agenda. A maximum of two experts per country are invited to each meeting.

    The sixth meeting of the GMO Network, held in May 2015, was attended by 42 scientific experts from 25 Member States and Norway, one observer from Switzerland, two hearing experts invited as speakers, one representative of the European Commission (Directorate General for Health and Consumers – DG SANTE), five EFSA GMO Panel members, and 14 EFSA scientific staff members from the GMO and Evidence Management (DATA) Units.

    At the sixth meeting of the GMO Network, the appointed experts were informed about follow-up activities to the discussions held at the fifth meeting of the GMO Network, active mandates of the EFSA GMO Panel, including GMO applications, risk assessment guideline development, requests for scientific advice, and procurement contracts. This was followed by discussions on the draft guidance on agronomic and phenotypic characterisation of GM plants and the draft guidance document for the risk assessment of the renewal of GM plant products authorized under Regulation (EC) No 1829/2003. Two breakout sessions were organised according to the expertise of the two groups of experts, to allow in-depth discussion of specific topics. The experts in the field of MC/FF discussed the use of EFSA Comprehensive European Food Consumption Database for estimating dietary exposure to GM foods. The experts in the ERA field discussed EFSA’s self-task activity to supplement its previous risk mitigation measures reducing exposure of non-target Lepidoptera to maize MON 810, Bt11 or 1507 pollen. At the following joint plenary session, the GMO Network experts discussed with the invited speakers risk assessment considerations for plants developed by new plant breeding techniques or synthetic biology, and for second generation GMOs respectively. This was followed by a discussion on the use of negative segregants in the comparative assessment of GMOs. EFSA also presented its Document Management System and shared information on upcoming scientific events.

    In 2015, GMO Network experts participated in two EFSA meetings relevant for the risk assessment of GMOs. The first one was the 96th GMO Panel plenary meeting, which was held in Brussels on 4-5 March 2015. During this meeting, the draft guidance document on agronomic and phenotypic characterisation of GM plants and the draft guidance for the risk assessment of the renewal of GM plant products authorised under Regulation (EC) No 1829/2003 were discussed. GMO Network members expressed their views and asked questions related to these draft documents, in their quality as observers to this meeting. The second one was the ‘Workshop on allergenicity assessment of GM plants’, held in the context of guidance development in Brussels, on 17 June 2015. The objective of this workshop was to involve stakeholders at an early stage of the guidance development and to enhance their participation in EFSA scientific work. GMO Network members actively participated to the discussions held at this workshop and provided valuable input.

    • To enhance cooperation with Member States on specific topics, EFSA established in 2010 Scientific Networks, among which the Network for Risk Assessment of Nanotechnologies in Food and Feed. This Network is used to facilitate harmonisation of assessment practices and methodologies, to enhance exchange of information and data between EFSA and Member States and to achieve synergies in risk assessment activities. The Annual reports of the Network inform the public, stakeholders, research community, risk assessment community and the EFSA Advisory Forum about its specific activities and advice. During 2015, the Network followed-up on its priority topic to discuss test methods and test results that are relevant for risk assessments at EFSA. At its 2015 meeting, twenty Network experts participated and focussed on issues that merit further method development or scientific unravelling such as the physico-chemical characterisation, the role of solubility/shape/coating in translocation mechanisms and toxicity as well as the risk assessment of soft nanomaterials and the fate and effects of nanoparticles in the environment. Updated information was presented by the Joint Research Centre and a representative of the EU Framework Program 7 project NanoDefine on the technical aspects and implementation of the EC Recommended definition for Nanomaterial. The Network received overviews of the activities on nanomaterials in the European Chemicals Agency and the European Medicines Agency, based on which synergies and common needs were further explored. The Network also exchanged views on the risk assessment of applications (being) assessed at EFSA and comprising implicitly or explicitly nanoforms. The list with national research projects and the list with contact details of national laboratories that can analyse nanomaterials in complex matrices were updated.

    • 日前,欧洲食品安全署(EFSA)发布了关于转基因大豆305423和40-3-2两种品系新的测序研究结果。 转基因生物研究小组目前就转基因大豆305423单一品系及双品系305423×40-3-2杂交组成部分来进行检测评估。这些品系的大豆经科学检测,其安全性与普通种类或其他类似植株一样,不会对人类和其他动物个体健康和生存环境造成威胁。2017年2月,欧盟委员会(EC)要求欧洲食品安全署(EFSA)对转基因大豆305423品系进行核酸序列测定,更新相关的生物信息学数据,以验证转基因生物研究小组之前对其作出的评估结果是否仍然有效。 研究表明,单品系305423转基因大豆与双品系杂交系305423×40-3-2之前的评估测定结果仍旧有效。而且,新的测序数据及其相应生物学分析研究,包括RNA脱靶搜索干扰,并没有引起安全问题。由此,欧洲食品安全署(EFSA)得出结论:之前做的关于品系305423转基因大豆与双品系杂交系305423×40-3-2的评估报告截至目前仍然有效。 同样地,转基因生物研究小组针对转基因大豆40-3-2单一品系及双品系305423×40-3-2杂交组成部分来进行检测评估。并且这些大豆品系的检测评估结果与305423品系相同,其安全性与普通种类或其他类似植株一样,不会对人类和其他动物个体健康和生存环境造成威胁。2017年4月,欧洲食品安全署(EFSA)对转基因大豆40-3-2品系进行新的核酸序列测定,更新了相关的生物信息学数据,验证了转基因生物研究小组之前对其作出的评估结果是否仍然有效。研究表明,单品系40-3-2转基因大豆与双品系杂交系305423×40-3-2之前的评估测定结果仍旧有效。而且,对新的测序数据的生物学分析也并没有显示出安全性问题有任何提升。因此,欧洲食品安全署(EFSA)得出结论:基于目前掌握的数据,转基因大豆40-3-2单一品系及双品系305423×40-3-2的原始风险评估仍旧有效。 需要了解更多信息,请查阅相关欧洲食品安全署期刊,以了解转基因大豆305423和40-3-2两个品类的更多资料。
