RESUMEN
The dynamic field of food safety faces continuous challenges, prompting stakeholders to develop collaborative actions for improved food safety systems. As part of these actions, the EU-FORA fellowship programme was dedicated to a multi-actor collaboration addressing risks of the unregulated mycotoxins T-2 and HT-2 toxins in oats. Critical gaps in risk assessment procedures were identified, leading to a joint effort to develop a strategy for rapid data collection and risk assessment, including the development of a risk assessment toolkit comprising of a training manual and two intuitive Microsoft® Excel files. The toolkit enables efficient data collection and processing, facilitating risk assessment calculations and rapid risk detection. Applying the toolkit to assess T-2 and HT-2 toxin risks in Belgian oats revealed minimal concerns, except for children aged 3-9 years, likely due to an overestimation. The toolkit is available on the FoodSafety4EU Platform and will be refined based on user feedback, promoting better risk assessment practices. This approach empowers stakeholders, from professionals to policymakers, fostering collaboration and enhancing food safety practices.
RESUMEN
Food safety is a top priority for the European Commission, which policies aim at sustaining a high level of protection of human health and consumers' interests, while ensuring an effective functioning of the internal EU market. Under the New Transparency Regulation (EU/2019/138), the 3-year EU-funded foodsafety4eu project (FS4EU) kicked off in January 2021, represents a significant step for the European Union (EU) food safety system (FSS), towards more transparency, better engagement, and closer cooperation. This Horizon 2020 Project, coordinated by CNR-ISPA (Italy), focuses on building a multi-stakeholder platform for the future EU FSS. The foodsafety4eu Network currently consists of 23 consortium partners and around 50 stakeholders: Food Safety Authorities (FSA), consumer associations, academia, research centres and networks, food industries and sector associations, thinktanks, etc. Through a structured, digitally supported, participatory process, the platform hosts the co-design of future strategic research and innovation agenda (SRIA), as well as risk communication models tailored to the specificities of various target groups. Among the goals: providing scientific advice and technical support for EU food safety policies, by enabling actors to access, share and exchange scientific knowledge, resources, and data more efficiently, to better synchronise food safety research and policies, and to contribute to a more transparent communication through the FSS. Overall, the FS4EU project underpins the EFSA missions in risk assessment, including risk communication, with the ambition to be a basis for a Knowledge Centre for Food Safety in Europe. Accordingly, the EU-FORA 2021-2022 fellow (based in CNR-ISPA under the Work Programme RECIPE: Risk AssEssment/Risk CommunIcation: understanding the context and addressing Priorities of the futurE - a learning-by-doing approach) committed to multiple Work Packages, actively participated to various activities, thus successfully contributing to the FS4EU project meeting its objectives by the end of 2023.
RESUMEN
BACKGROUND: Seed germination is a key phase of the parasitic plant life cycle that is stimulated by the secondary metabolites, mainly strigolactones (SLs), secreted by the host roots. Interventions during this stage would be particularly suitable for parasitic weed management practices, as blocking these chemical signals would prevent seed germination and thus parasite attack. Four fungal strains with different ecological functions were considered for their possible ability to metabolise SLs: Fusarium oxysporum and F. solani, biocontrol agents of Phelipanche ramosa; Trichoderma harzianum, a potential biopesticide; Botrytis cinerea, a phytopathogenic fungus. Four different SLs [the natural strigol, 5-deoxystrigol (5DS) and 4-deoxyorobanchol (4DO), and the synthetic analogue GR24] were added to fungal cultures, followed by determination of the SL content by liquid chromatography-tandem mass spectrometry. RESULTS: Differences were observed among microorganisms, treatments and SLs used. T. harzianum and F. oxysporum were the most capable of reducing the SL content; considering the whole set of fungi used, 5DS and 4DO proved to be the most degradable SLs. CONCLUSIONS: Beneficial microscopic fungi could differently be used for biocontrolling parasitic weeds, acting as a 'physiological' barrier, by preventing the germination of their seeds through the ability to biotransform the stimulatory signals. © 2016 Society of Chemical Industry.
