Transforming the German Food System – How to Make Start-ups Great!

The food system represents a key industry for Europe and particularly Germany. However, it is also the single most significant contributor to climate and environmental change. A food system transformation is necessary to overcome the system's major and constantly increasing challenges in the upcoming decades. One possible facilitator for this transformation are radical and disrup-tive innovations that start-ups develop. There are many challenges for start-ups in general and food start-ups in particular. Various support opportunities and resources are crucial to ensure the success of food start-ups. One aim of this study is to identify how the success of start-ups in the food system can be supported and further strengthened by players in the innovation ecosystem in Germany. There is still room for improvement and collaboration toward a thriving innovation ecosystem. A successful innovation ecosystem is characterised by a well-organised, collaborative, and supportive environment with a vivid exchange between the members in the ecosystem. The interviewees confirmed this, and although the different actors are already cooperating, there is still room for improvement. The most common recommendation for improving cooperation is learning from other countries and bringing the best to Germany.

Dissection of Highly Prevalent qnrS1-Carrying IncX Plasmid Types in Commensal Escherichia coli from German Food and Livestock

Plasmids are mobile genetic elements, contributing to the spread of resistance determinants by horizontal gene transfer. Plasmid-mediated quinolone resistances (PMQRs) are important determinants able to decrease the antimicrobial susceptibility of bacteria against fluoroquinolones and quinolones. The PMQR gene qnrS1, especially, is broadly present in the livestock and food sector. Thus, it is of interest to understand the characteristics of plasmids able to carry and disseminate this determinant and therewith contribute to the resistance development against this class of high-priority, critically important antimicrobials. Therefore, we investigated all commensal Escherichia (E.) coli isolates, with reduced susceptibility to quinolones, recovered during the annual zoonosis monitoring 2017 in the pork and beef production chain in Germany (n = 2799). Through short-read whole-genome sequencing and bioinformatics analysis, the composition of the plasmids and factors involved in their occurrence were determined. We analysed the presence and structures of predominant plasmids carrying the PMQR qnrS1. This gene was most frequently located on IncX plasmids. Although the E. coli harbouring these IncX plasmids were highly diverse in their sequence types as well as their phenotypic resistance profiles, the IncX plasmids-carrying the qnrS1 gene were rather conserved. Thus, we only detected three distinct IncX plasmids carrying qnrS1 in the investigated isolates. The IncX plasmids were assigned either to IncX1 or to IncX3. All qnrS1-carrying IncX plasmids further harboured a β-lactamase gene (bla). In addition, all investigated IncX plasmids were transmissible. Overall, we found highly heterogenic E. coli harbouring conserved IncX plasmids as vehicles for the most prevalent qnr gene qnrS1. These IncX plasmids may play an important role in the dissemination of those two resistance determinants and their presence, transfer and co-selection properties require a deeper understanding for a thorough risk assessment.

Toward the commoning of governance

Conventional political thought and practice continue to be stifled by a dilemma of choosing between the ideal imaginaries of State and/or Market solutions. Widely presupposed as the only valid possibilities in both theory and practice, this stale dilemma covers up a real multitude of actually existing alternative approaches to governance practiced in civil society. State/Market approaches are identical in the way that they construct a ‘spectator’ role for communities, who are left to choose between their preferred set of rules and norms developed elsewhere. The concept of commoning governance offers an opportunity to break free of this stalemate. It creates a new role for citizens and their communities as ‘sparring partners’; who although they operate within the limits of current State/Market institutions, create new norms and rules against and beyond them. In the paper, we first expand on our understanding of commoning governance: re-designing governance arrangements to serve the common good. That is here understood in terms of (radical) democracy, solidarity and sustainable ecological relationships. Second, we illustrate how commoning efforts on the ground contribute to the reclaiming of the democratic imaginary as a political arena by zooming in to a case study of the three cities involved in civic-led network of German Food Policy Councils. Finally, we reflect on the empirical barriers that communities of commoning endure, and call on policymakers, planners and scholars to interrogate their own normative understandings of citizenship and democracy, and begin to recognize theoretical and latent possibilities by enabling commoning with new or re-designed institutions of governance.

Phenotypic and Genotypic Properties of Fluoroquinolone-Resistant, qnr-Carrying Escherichia coli Isolated from the German Food Chain in 2017

Fluoroquinolones are the highest priority, critically important antimicrobial agents. Resistance development can occur via different mechanisms, with plasmid-mediated quinolone resistance (PMQR) being prevalent in the livestock and food area. Especially, qnr genes, commonly located on mobile genetic elements, are major drivers for the spread of resistance determinants against fluoroquinolones. We investigated the prevalence and characteristics of qnr-positive Escherichia (E.) coli obtained from different monitoring programs in Germany in 2017. Furthermore, we aimed to evaluate commonalities of qnr-carrying plasmids in E. coli. We found qnr to be broadly spread over different livestock and food matrices, and to be present in various sequence types. The qnr-positive isolates were predominantly detected within selectively isolated ESBL (extended spectrum beta-lactamase)-producing E. coli, leading to a frequent association with other resistance genes, especially cephalosporin determinants. Furthermore, we found that qnr correlates with the presence of genes involved in resistance development against quaternary ammonium compounds (qac). The detection of additional point mutations in many isolates within the chromosomal QRDR region led to even higher MIC values against fluoroquinolones for the investigated E. coli. All of these attributes should be carefully taken into account in the risk assessment of qnr-carrying E. coli from livestock and food.
