- The plant microbiome is an important factor for plant health and productivity. While the impact of nitrogen (N) availability for plant growth and development is well established, its influence on the microbial phyllosphere community structure is unknown. We hypothesize that nitrogen impacts the growth and abundance of several microorganisms on the leaf surface. The bacterial and fungal communities of baby leaf spinach (Spinacia oleracea), and rocket (Diplotaxis tenuifolia) were investigated in a field trial for two years in a commercial setting. Nitrogen fertilizer was tested in four doses (basic nitrogen, basic + suboptimal, basic + commercial, basic + excess) with six replicates in each. Culture-independent (Illumina sequencing) and culture-dependent (viable count and identification of bacterial isolates) community studies were combined with monitoring of plant physiology and site weather conditions. This study found that alpha diversity of bacterial communities decreased in response to increasing nitrogen fertilizer dose, whereas viable counts showed no differences. Correspondingly, fungal communities of the spinach phyllosphere showed a decreasing pattern, whereas the decreasing diversity of fungal communities of rocket was not significant. Plant species and effects of annual variations on microbiome structure were observed for bacterial and fungal communities on both spinach and rocket. This study provides novel insights on the impact of nitrogen fertilizer regime on a nutrient scarce habitat, the phyllosphere.

Tidskriftsartikel (refereegranskat)abstract
- Empiriska studier om lärares kompetens för undervisning inom utbildning för hållbar utveckling (UHU) är efterfrågade, men få forskningsinstrument finns tillgängliga. Studiens syfte är att ta fram ett enkätinstrument som kan beskriva lärares kompetens att implementera UHU. Ett andra syfte är att undersöka samband mellan UHU-kompetens och bakgrundsvariablerna: kön, ålder, undervisningsämne och antal år i yrket. I studien undersöks gymnasielärares (n=183) förhållningssätt till undervisning om UHU på en skola med ett uttalat UHU-arbete där förhållningssätt ses som ett uttryck för lärares UHU-kompetens. Utvecklingen av enkätinstrumentet baseras på det internationellt vedertagna OECD-ramverket DeSeCo:s (Definition and Selection of Competencies) definition av kompetensbegreppet. Explorativ faktoranalys identifierade fyra dimensioner av UHU-kompetens: didaktik, motivation, kapacitet och hinder. Inga korrelationer hittades mellan dimensionerna och bakgrundsvariablerna, vilket kan bero på en gemensam skolkultur. I framtida studier behöver instrumentets validitet för lärare som inte arbetat med UHU studeras.

Tidskriftsartikel (refereegranskat)abstract
- The influence of organic nitrogen sources on the establishment of E. coil 0157:H7 and the occurrence of other potentially human pathogenic bacteria on baby leaf salads was evaluated. Greenhouse-grown rocket and Swiss chard were spray-inoculated with gfp-tagged E. coil 0157:H7 twice a week from when their first true leaves reached a length of 2 cm until three days before harvest. Analysis of nitrogen content in leaves revealed differences between treatments. Untreated plants had the lowest values, followed by plants fertilized with pig hair pellets and chicken manure. The same pattern was seen for the growth medium at the day of harvest. The applied strain showed similar establishment (measured using culture-dependent methods) irrespective of treatment, but Swiss chard hosted significantly more E. coli 0157:H7 than rocket. Differences in the risk of infection were found for the crops, with plants fertilized with pig hair pellets showing a slightly higher risk. No relationship was found for total nitrogen content in leaves and colonization with E. coli 0157:H7 gfp+. Isolating dominant Enterobacteriaceae from leaves, some strains showed conformity to bacterial species that have previously been identified to influence the establishment of E. coli 0157:H7 in the phyllosphere. In this study, no inhibitory effects were observed in vitro.Colonies showing matching characteristics for Listeria spp. and Salmonella spp. were detected up to 5.5 and 5 log CFU g(-1) fresh weight, respectively. However, presumptive Listeria spp. and Salmonella spp. could not be confirmed by sequencing of the 16S rRNA gene. (C) 2017 Elsevier Ltd. All rights reserved.

Conceptual work on ESD from a school improvement perspective
- 2018
-
Konferensbidrag (refereegranskat)abstract
- Chair: Anna Mogren, PhD, Karlstad University SwedenDiscussant: Professor Arjen Wals, Wageningen University, The Netherlands & Gothenburg University,SwedenThis symposium places Education for Sustainable Development ( ESD) within the field of school improvementtheory and research. In a number of studies, the Whole school approach in ESD is suggested and referred toas the work of embedding ESD into existing school visions and action plans (Breiting, Mayer & Mogensen2005 “Quality Criteria for ESD-schools”; Hargreaves 2008; Scott 2013.) The symposium therefore focuses onhow the research field of school improvement – which investigates, how efforts to help schools becomeincreasingly effective learning environments for the full range of their students have been more or lesssuccessful – might inform and challenge ESD and the ESD the Whole school approach.If ESD is to be framed and studied from a “within perspective” as an ongoing school improvement processrather than as an add-on activity to existing organisational arrangements and educational practices, it isnecessary to discuss models of school improvement in terms of their contribution to ESD. It is also importantto identify models of school improvement that can identify drivers and barriers for ESD implementation atorganisational level as well as on teaching and learning level (see Scherp 2013; Reezigt & Creemers 2005“Comprehensive framework for effective school improvement” ; Rolff 2010 “Trias of school development”;Rolff 2002 “P.dagogische Qualit.tsmanagement (PQM)”.In school improvement theory, a school’s organisation is commonly understood as reflexive in relation tocontext and supportive to the action of all members of the school community and their cooperation.Further, research suggests there are basic mechanisms contributing to effective school improvement such asgoal setting for improvement, pressures to improve, cyclical improvement processes and autonomy (seeScheerens & Demeuse 2005). Further, the school culture ought to be build up on dialogue supported byschool leadership. By this definition of school organisation, school improvement refers to collectivelysupporting factors in the organisation, to the end that students’ possibilities for learning in relation to acomplex surrounding world are enhanced.The recognition of multiple perspectives within the school organisation, e.g. cultural, structural, political andtransformational is central in investing possible models of school improvement. The search for schoolimprovement models that can discern those perspectives that are closely linked to ESD is crucial. Suchmodels of school improvement have the potential to constitute the link between the research fields of ESDand school improvement. They could serve as a tool for further research on how the Whole school approachis constructed in formal education, which is searched for in the practical work on ESD implementation.In this symposium examples from ongoing research projects on ESD where models of school improvementare used, considered or asked for in a German, Swedish and Hungarian context are presented. Thesymposium will explore the potential of integrating, adapting and rejecting theoretical perspectives andempirical evidence from school improvement into the ESD research field through intention papers with thegoal of developing knowledge about- how selected conceptual work on the Whole school approach in ESD draw on models andperspectives from school improvement theory,- how in an empirical case study a school improvement model was used to measure the ESD Wholeschool approach,- how school improvement has informed efforts and plan for upscaling ESD implementation in Eco-Schools to a larger number of public schools.Following questions from the audience, Arjen Wals (Wageningen University, The Netherlands & GothenburgUniversity, Sweden) will draw together the discussion and to explore implications for research in ESD.

- Research on Education for Sustainable Development (ESD) implementation tends to focus primarily on student and teacher outcomes, and there have been few studies on leadership practices at the school organisation level that provide information on how quality in education contributes to ESD implementation. To address this issue, we conducted an empirical mixed methods study of existing practices in 10 highly ESD-active upper secondary schools in Sweden. The schools’ principals, who were responsible for implementing ESD, were interviewed to obtain information on the quality criteria they used to guide their work. Twenty-six criteria were identified and grouped into four main principal quality criteria on the basis of statistical analysis: Collaborative interaction and school development; Student centred education; Cooperation with local society; and Proactive leadership and continuity. This categorization both supports existing research on ESD quality criteria and highlights new criteria that are important but were previously unrecognized. Trends in the identified quality criteria are discussed and related to prior research in order to identify potentially fruitful school leadership and management for implementing ESD at the school organisational level.

Tidskriftsartikel (refereegranskat)abstract
- Previous research has suggested that adopting a transformative school organisation perspective when implementing ESD may be more productive than the previously recommended transmissive perspectives, but it is not clear how transformative perspectives could be introduced. To address this issue, we conducted an empirical mixed methods study of existing practices in 10 highly ESD-active upper secondary schools in Sweden. The schools’ leaders, who were responsible for implementing ESD, were interviewed to obtain information on the quality criteria they used to guide their work. The arguments used by the leaders to justify their criteria were analysed and categorised based on their relationships with the transmissive and transformative quality strategies. Both school organisation perspectives were found to co-exist within the schools. A detailed analysis of schools where the transformative perspective was dominant revealed three distinct quality strategies, one of which was found to embody a strong focus on a transformative approach. This specific quality strategy is discussed and suggested as a way for interested schools to implement ESD in a more transformative way at the school organisation level.

Failed Quality in ESD Implementation : School Leaders in Evidence Seeking of School Legitimacy to Become Whole School Organisations
- 2017
-
Konferensbidrag (refereegranskat)abstract
- This study seeks to investigate and understand the already established anchoring structures of quality education in schools that actively implement ESD (Laurie, Nonoyama-Tarumi, Mckeown and Hopkins 2016). The anchoring structures on leadership level are criticised for building cultures of standards and conformity (Bottery Wright and James 2012), rather than progress change and renewal in education, which is considered a way to prevent a negative societal development (Huckle and Wals 2015). Standards and conformity is found to coexist with transformative expressions of progress and change in education. In recent research the anchoring qualities are criticised as being too structural, predefined and apart from a real school context (Scott in Jucker and Reiner 2015) and referred to as counteracting a fruitful ESD implementation (Peters, Michael and Wals 2016; Lotz-Sisitka, Wals, Kronlid and McGarry 2015).The focus of this study is to outline which role the qualities that constitute structures and conformity (in this study called transmissive) play in schools, and what specific quality criteria the empirics underpin as necessary structures that anchor quality at ESD active schools? Qualities in transformative ESD implementation distinguish from qualities in transmissive ESD implementation. The gap between these two ESD implementation strategies can be described by qualities related to improve schools in transmissive ESD implementation to qualities used to develop schools in transformative ESD implementation (Hargreaves 2008). The term ESDquality criteria is a specific term used in studies that directly inquired about the qualities related to ESD settings in education (Breiting, Mayer and Mogensen 2005). The study investigates the school leaders understanding of transmissive quality criteria at ESD active schools and especially those appointed high importance in the school organisation.The authors have in earlier studies investigated ESD implementation at school organisation level with the focus of qualities that are process orientated (transformative). It was found that the school organisations most frequently based on transformative qualities in education also displayed the highest degrees of transmissive qualities (Mogren and Gericke a, b). The result of high levels of transmissive qualities in schools with a successful ESD implementation created research interest for their role. The study also intends to indicate transmissive quality criteria that seems to threatens a sound ESD implementation in that they display a vague anchoring function or hinder the transformative ESD implementation. The study will answer the questions:1, What characterizes the transmissive weighted quality criteria that ESD active schools use (as anchoring) in governing a school organisation of high quality?2, Can the realization of ESD WSA at teacher level indicate which transmissive weighted quality criteria (anchors in quality criteria) that is important for a school organisation to consider?The experience of schools with an active ESD implementation is informative and crucial in breaking new ground for ESD of a high quality (Jucker and Reiner2015). Research based on school leadership within such schools is accounted for in the study. Temporarily ´role model-schools´ are used to stand model and learn from for schools seeking information and proof on the power of a transformative ESD implementation as to redirect education to a higher quality in accordance to the local and global sustainability problems (Hargreaves 2008; Laurie, Robert, et al. 2016).The attention given to the transmissive quality criteria in this study is an attempt to find the anchoring structures that not previously has been the central interest for researchers studying ESD implementation (Schwarzin 2012). Rickinson, Hall and Reid (2016) urge the need to be more curious to which factors that do make implementation programmes to work overtime beyond the fact that they are present as a tool within educational settings.In this study two different datasets are used that relates to two levels of the same school organisations. One dataset is collected at the school leader level by interviews with principals. The other dataset is based on a questionnaire study with teachers. ESD schools from a Swedish nationwide sample are identified. This is done by investigating the schools ESD activity in national ESD award systems and national databases on ESD schools. The 10 most active ESD schools are selected and validated by interviewing local school personal and ESD stakeholders. In the first data collection semi structured interviews were conducted with the principals. The main objective for the interviews was to collect data about the way principals choose to organize their schools in relation to their perception of high quality in education. During the interviews concept maps were constructed by the researcher based on the interviewees’ statements. The concept maps hold information of which quality criteria that were highlighted by different schools, and the argumentation for those choices. The trustworthiness of the concept map is confirmed by each principal. Qualitative data in the form of concept maps are translated into quantitative data by using an assessment system in which each quality criteria were given a score depending on the emphasis given by the principal. The scores separate transmissive and transformative statements. The statements formed 26 quality criteria. In this study, we compare the ranking of single quality criteria to their ranking as transmissive weighted. We identify in that way the transmissive quality criteria that is used to anchor ESD. Excerpts by school leaders help us to interpret quantitative data. The datasets on teacher level at selected ESD schools consist of a survey about school development measuring the teacher’s opinion on quality in school development. This survey was developed and used within a larger school development project in Sweden (Scherp 2013). It is an operationalisation of a school organisation model. The model is used to understand high quality in ESD active schools in an earlier study by the Authors. This study assumes the use of the model one step further; as a tool to define ESD Whole School Approach, WSA. We define what is meant by WSA and explain how the model can be used to judge the realisation of WSA at ESD active schools. This allows an identification of transmissive qualities used in schools realising ESD.Our research contributes to an empirically based understanding on the impact of the transmissive quality criteria at school organization level in schools with an active ESD implementation. This gives new arguments and input to the design of implementation programmes on ESD that holds the ambition to scale up ESD. Universally the study also contributes to the definition on quality education related to actual policy documents on ESD realisation, Global Action Programme on ESD (UN 2014). The concept of Whole School Approach, WSA is introduced as the benchmark for high quality in education. Finally, the study is designed with an interdisciplinary approach where the ESD research field rapproach the research field of educational organisation and leadership, which contributes to a modest field of research. Our first results indicate that political support is an important transmissive weighted quality criterion that leads to ESD WSA implementation. I Hence, the sharing of ideological ideas within the school or networks to measure one owns practice and organisation against seems to be an important anchoring for ESD implementation. School organisation with a lower realization of ESD WSA search their legitimization of school organisation in evidence by external actors but seems less successful in their strategy. At time for the ECER conference we foresee that we will have even more detailed results to share.

Guiding Principles of Transformative Education for Sustainable Development in Local School Organisations : Investigating Whole School Approaches through a School Improvement Lens
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The importance of an education that empowers students to engage with real societal problems to promote a sustainable future is widely acknowledged. However, the organisational characteristics of schools that facilitate such education for sustainable development (ESD) have received little attention. This thesis aims to fill this research gap by contributing new knowledge on ways that school organisations can implement transformative ESD, while aligning with a whole school approach.Swedish upper secondary schools actively implementing ESD were selected for the study. The research design used a mixed-method approach developed from the field of school improvement research. Methods included semi-structured interviews with school leaders and questionnaire surveys for teachers. School leaders’ and teachers’ understanding of quality in their local school organisation was studied.The thesis identifies the guiding principles that school leaders and teachers found important for promoting transformative ESD. These include four principal quality criteria that need structural support through collegial meetings to establish a holistic idea of ESD, namely collaborative interaction and school development, student-centred education, cooperation with local society, and proactive leadership and long-term perspective. With the support of the guiding principles, the whole school organisation contributes to teaching and learning practices in ESD active schools.The two main contributions are 1) identification of the school organisation that provide firm ground for local implementation of transformative ESD, and 2) that the internal school organisation is a prerequisite for school collaboration with the surrounding society, which is a main goal of ESD, according to policy and theory. In the case of the latter, a student-centred approach in organising education was found to facilitate such links between education and the community, which is a main goal of ESD, according to policy and theory. The results may provide useful recommendations for schools and ESD implementation programmes.

Implementering av lärande för hållbar utveckling : En studie av rektors förståelse av kvalitet i skolans organisation
- 2017
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Student outcomes of Education for Sustainable Development (ESD) is reported to be weak and empirical studies investigating the underlying causes have been called for. School organization is pointed out as essential, which highlights the role of school leaders in realizing ESD. This study aims to identify characteristic features of ESD active school organizations, by investigating how school leaders maintain high quality in their organizations. ESD is thus studied from an internal organizational perspective. Fourteen school leaders at ten upper secondary schools, active in ESD implementation, were interviewed and qualitative data quantified. A special focus was on school leaders’ transformative statements, in response to earlier criticism that ESD implementation has been too structural. Results consist of 26 identified quality criteria. By means of cluster analysis, the quality criteria were merged into four principal quality criteria: collaborative interaction and school development, student-centred education, cooperation with local society and proactive leadership and continuity. The school leaders’ quality strategies were identified through correlation analysis of their principal quality criteria. The quality strategies reveal a difference in the schools’ internal or external focus. An analysis of the school leaders’ quality statements in relation to their quality strategy implementation indicates that ESD to a large degree is introduced from a transformative perspective. One school in the study stands out as highly transformation-oriented, and has a quality strategy combining an internal and external focus, thus making it a possible benchmark for successful ESD-implementation. The study contributes a suggestion on how a progression of ESD implementation can take place and as well as possible obstacles.

Tidskriftsartikel (refereegranskat)abstract
- In this article, we consider the problem of ensuring that Education for Sustainable Development (ESD) is firmly embedded in a school through appropriate management and planning of the school’s activities (or characteristics of the school organization). To this end, we identify the domains of school organization that would benefit from particular structures and routines in order to embed ESD. We identify these domains by thematically analyzing responses of interviewed leaders of schools employing a transformative approach to ESD. We divided the leaders into two groups, based on the extent to which their respective schools employed a transformative approach to ESD. We analyzed the differences in responses of the two groups, enabling us to identify and compare the structures that school leaders in the respective groups believe to be important. In addition to reporting the results, we discuss their implications. We focus particularly on how structures identified by leaders of highly transformative schools could contribute to long-lasting transformative implementation of ESD, and how structures identified by leaders of the other group could be used to circumvent barriers to such implementation.

The work of higher education institutions to promote sustainable development
- 2018
-
Konferensbidrag (refereegranskat)abstract
- In March 2016, the Swedish Higher Education Authority (UKÄ) was tasked by the Swedish government to conduct an evaluation of how universities and university colleges promote sustainable development, pursuant to the provisions of the Higher Education Act (1992:1434) introduced ten years earlier, 2006. The evaluation has resulted in a unique collection of empirical material that would have been difficult for an individual researcher to collect independently. The evaluation includes an analysis, but is related to background theory not a strict scientific study. The empirical material could, however, form a basis for numerous interesting studies on, for example, the important factors for successfully working to integrate sustainable development into higher education. A comparison between nations is also possible to conduct based on the methodology of self-reporting by Higher Education institutions, HEI:s. The evaluation defined sustainable development by the Bruntland detention, that the present and future generations are ensured a healthy and good environment, financial and social welfare, and justice. The evaluation was limited to the educational area of sustainable development, education for sustainable development ESD. The purpose of the evaluation was to contribute with knowledge and a national comparison of HEIs, work with ESD, and also to present the results that have been achieved so far. The evaluation was further conducted to give support to the HEIs development work on ESD. Success factors of a positive ESD implementation due to pre-defined criteria were identified in the evaluation; the significance of management and control, building institutional support and providing support in implementation. Apart from investigated criteria, factors that showed effects on a positive ESD implementation was also identified in the evaluation. An example is that several of the large and medium-sized HEIs referred their ESD work from teaching- and engineering programmes, which is the only two programmes where sustainable development is included in the national qualitative programme targets. Central bodies with specific responsibilities for sustainable development was also appointed an important structure in translating ESD policy document to the local context and practice. An interesting finding was the link between HEIs rated high in this evaluation, to institutions with an environmental management system intended to improve the organisation’s environmental performance and contribute to national environmental goals and to the achievement of UN global goals for sustainable development. Such system takes a wider responsibility of sustainable development than education but seems influential and important in HEIs ESD work. A remaining challenge for a majority of HEIs in Sweden is the process of sustainable development in education where the ESD perspective is not only accounted for as a specific content in education but also a driving force to reach high quality education and society transformation.

Tidskriftsartikel (refereegranskat)abstract
- This study applies a model of school organisation developed by one of the authors to investigate school improvement processes leading to a whole school approach in Education for Sustainable Development (ESD) literature. The model is operationalized to a survey instrument and distributed to Swedish upper secondary teachers. The instrument provides empirical indications of teachers’ perceptions of their schools in terms of four major dimensions of an ESD whole school approach, the importance assigned to a holistic vision, routines and structures, professional knowledge creation, and practical pedagogical work. The aims of the study are to compare the teachers’ perception of their school organisation. We compare perceptions of teachers working in schools actively implementing ESD and teachers in comparable reference schools. Comparisons are also made between teachers from schools applying different strategies and quality approaches in implementing ESD. The results indicate that, relative to teachers in ordinary schools, those in ESD schools perceive their school organisations to have higher quality and coherence, with greater potential to support teaching and pedagogical work in practice. However, there is substantial variation in perceptions of teachers from different ESD schools. The model’s robustness is validated by coherence of earlier results in the same schools.

The hurdle approach-A holistic concept for controlling food safety risks associated with pathogenic bacterial contamination of leafy green vegetables. A review
- 2018
-
Ingår i: Frontiers in Microbiology. - : Frontiers Media SA. - 1664-302X. ; 9:AUG

Forskningsöversikt (refereegranskat)abstract
- Consumers appreciate leafy green vegetables such as baby leaves for their convenience and wholesomeness and for adding a variety of tastes and colors to their plate. In Western cuisine, leafy green vegetables are usually eaten fresh and raw, with no step in the long chain from seed to consumption where potentially harmful microorganisms could be completely eliminated, e.g., through heating. A concerning trend in recent years is disease outbreaks caused by various leafy vegetable crops and one of the most important foodborne pathogens in this context is Shiga toxin-producing Escherichia coli (STEC). Other pathogens such as Salmonella, Shigella, Yersinia enterocolitica and Listeria monocytogenes should also be considered in disease risk analysis, as they have been implicated in outbreaks associated with leafy greens. These pathogens may enter the horticultural value network during primary production in field or greenhouse via irrigation, at harvest, during processing and distribution or in the home kitchen/restaurant. The hurdle approach involves combining several mitigating approaches, each of which is insufficient on its own, to control or even eliminate pathogens in food products. Since the food chain system for leafy green vegetables contains no absolute kill step for pathogens, use of hurdles at critical points could enable control of pathogens that pose a human health risk. Hurdles should be combined so as to decrease the risk due to pathogenic microbes and also to improve microbial stability, shelf-life, nutritional properties and sensory quality of leafy vegetables. The hurdle toolbox includes different options, such as physical, physiochemical and microbial hurdles. The goal for leafy green vegetables is multi-target preservation through intelligently applied hurdles. This review describes hurdles that could be used for leafy green vegetables and their biological basis, and identifies prospective hurdles that need attention in future research.

- Background: Despite the recommendations to continue the regime of healthy food and physical activity (PA) postpartum for women with previous gestational diabetes mellitus (GDM), the scientific evidence reveals that these recommendations may not be complied to. This study compared lifestyle and health status in women whose pregnancy was complicated by GDM with women who had a normal pregnancy and delivery. Methods: The inclusion criteria were women with GDM (ICD-10: O24.4 A and O24.4B) and women with uncomplicated pregnancy and delivery in 2005 (ICD-10: O80.0). A random sample of women fulfilling the criteria (n = 882) were identified from the Swedish Medical Birth Register. A questionnaire was sent by mail to eligible women approximately four years after the pregnancy. A total of 444 women (50.8%) agreed to participate, 111 diagnosed with GDM in their pregnancy and 333 with normal pregnancy/ delivery. Results: Women with previous GDM were significantly older, reported higher body weight and less PA before the index pregnancy. No major differences between the groups were noticed regarding lifestyle at the follow-up. Overall, few participants fulfilled the national recommendations of PA and diet. At the follow-up, 19 participants had developed diabetes, all with previous GDM. Women with previous GDM reported significantly poorer self-rated health (SRH), higher level of sick-leave and more often using medication on regular basis. However, a history of GDM or having overt diabetes mellitus showed no association with poorer SRH in the multivariate analysis. Irregular eating habits, no regular PA, overweight/obesity, and regular use of medication were associated with poorer SRH in all participants. Conclusions: Suboptimal levels of PA, and fruit and vegetable consumption were found in a sample of women with a history of GDM as well as for women with normal pregnancy approximately four years after index pregnancy. Women with previous GDM seem to increase their PA after childbirth, but still they perform their PA at lower intensity than women with a history of normal pregnancy. Having GDM at index pregnancy or being diagnosed with overt diabetes mellitus at follow-up did not demonstrate associations with poorer SRH four years after delivery.

- The food safety risk of Shiga toxin-producing Escherichia coli (STEC) infection per serving of leafy vegetables was investigated using a quantitative microbial risk assessment (QMRA) approach. The estimated level of E. coli O157 contamination was based on observed numbers of Enterobacteriaceae and E. coli on leafy vegetables grown and processed in southern Sweden from 2014 to 2016. Samples were collected before harvest, after washing, and at the end of shelf life. The observed counts were combined with data on the ratio of E. coli to E. coli O157 taken from earlier studies to estimate the probability of illness. The risks of STEC infection associated with species, either spinach (Spinacia oleracea) or rocket (Diplotaxis tenuifolia), growing season (spring or autumn), and washing (washed or not washed) were then evaluated. The results indicated that leafy vegetable species and growing season could be possible hurdles for reducing the food safety risk of STEC infection. At harvest, the probability of infection was 87% lower when consuming rocket compared with spinach and 90% lower when consuming leafy vegetables grown in spring compared with autumn. These relative risk reductions remained consistent even with other serving sizes and dose-response models. The lowest risk of STEC infection was associated with leafy vegetables early in the production chain, i.e., before harvest, while the risk increased during storage and processing. Consequently, the highest risk was observed when leafy vegetables were consumed at the end of shelf life. Washing had no effect on the food safety risk of STEC infection in this study. To improve the quality of QMRA, there is a need for additional data on the relationship between indicator organisms that can be easily enumerated (e.g., E. coli and Enterobacteriaceae) and E. coli strains that can cause STEC infection (e.g., E. coli O157) but are difficult to identify in food samples such as leafy vegetables.
