  ABSTRACT: The interdisciplinary EC consortium (the PEGASUS project) aimed to examine the issues raised by the development, implementation, and commercialisation of genetically modified (GM) animals, and derivative foods and pharmaceutical products. The results integrated existing social, (including existing public perception) environmental and economic knowledge regarding GM animals in order to formulate policy recommendations relevant to new developments and applications. The use of GM in farmed animals (aquatic, terrestrial, and pharmaceutical) was mapped and reviewed. A foresight exercise was conducted to identity future developments. Three case studies (aquatic, terrestrial, and pharmaceutical) were applied to identify the issues raised, including the potential risks and benefits of GM animals from the perspectives of the production chain (economics and agri-food sector) and the life sciences (human and animal health, environmental impact, animal welfare, and sustainable production). Ethical and policy concerns were examined through application of combined ethical matrix method and policy workshops. The case studies were also used to demonstrate the utility of public engagement in the policy process. The results suggest that public perceptions, ethical issues, the competitiveness of EU animal production, and risk-benefit assessments that consider human and animal health, environmental impact, and sustainable production need to be considered in EU policy development. Few issues were raised with application in the pharmaceutical sector, assuming ethical and economic issues were addressed in policy, but the introduction of agricultural GM animal applications should be considered on a case-by-case basis.

  ABSTRACT: Emerging and major infectious animal diseases can have significant international impact on social, economic and environmental level, and are being driven by various factors. Prevention and control measures should be prepared at both national and international level to mitigate these disease risks. Research to support such policy development is mostly carried out at national level and dedicated transnational research programmes are still in its infancy. This research reports on part of a process to develop a common strategic research agenda on emerging and major infectious diseases of livestock in Europe, covering a 5-15-year time span. A two round online Delphi study was conducted to explore the views of experts on issues relating to research needs on emerging infectious diseases of livestock in Europe. Drivers that may influence the incidence of emerging infectious animal diseases in both the short (next 5 years) and medium term (10-15 years) were identified. Drivers related to regulatory measures and biological science developments were thought to decrease the incidence, and socio-economic factors to increase the incidence of emerging infectious animal diseases. From the first round a list of threats to animal health was compiled and participants combined these threats with relevant drivers in the second round. Next to identifying threats to animal health, also possible mitigatory actions to reduce the negative impact of these threats were identified. Participants emphasised that interdisciplinary research is needed to understand drivers of emerging infectious animal diseases, as well as to develop prevention and control measures which are both socio-economic and technical. From this it can be concluded that interdisciplinary research combining both natural and social research themes is required. Some of the European member states research budget needs to be allocated so that effective prevention and mitigation strategies can be developed.

  Article: Impact of the European clinical trials directive on prospective academic clinical trials associated with BMT.

  L J Frewer, D Coles, I A van der Lans, D Schroeder, K Champion, J F Apperley
  [show abstract] [hide abstract]
  ABSTRACT: The European Clinical Trials Directive (EU 2001; 2001/20/EC) was introduced to improve the efficiency of commercial and academic clinical trials. Concerns have been raised by interested organizations and institutions regarding the potential for negative impact of the Directive on non-commercial European clinical research. Interested researchers within the European Group for Blood and Marrow Transplantation (EBMT) were surveyed to determine whether researcher experiences confirmed this view. Following a pilot study, an internet-based questionnaire was distributed to individuals in key research positions in the European haemopoietic SCT community. Seventy-one usable questionnaires were returned from participants in different EU member states. The results indicate that the perceived impact of the European Clinical Trials Directive has been negative, at least in the research areas of interest to the EBMT.

• Article: Consumer perceptions of best practice in food risk communication and management: Implications for risk analysis policy

  S. Cope, L.J. Frewer, J. Houghton, G. Rowe, A.R.H. Fischer, J. de Jonge
  [show abstract] [hide abstract]
  ABSTRACT: As a consequence of recent food safety incidents, consumer trust in European food safety management has diminished. A risk governance framework that formally institutes stakeholder (including consumer) consultation and dialogue through a transparent and accountable process has been proposed, with due emphasis on risk communication. This paper delivers actionable policy recommendations based on consumer preferences for different approaches to food risk management. These results suggest that risk communication should be informed by knowledge of consumer risk perceptions and information needs, including individual differences in consumer preferences and requirements, and differences in these relating to socio-historical context associated with regulation. In addition, information about what is being done to identify, prevent and manage food risks needs to be communicated to consumers, together with consistent messages regarding preventative programs, enforcement systems, and scientific uncertainty and variability associated with risk assessments. Cross-cultural differences in consumer perception and information preferences suggest a national or regional strategy for food risk communication may be more effective than one applied at a pan-European level.

• Article: How trust in institutions and organizations builds general consumer confidence in the safety of food: a decomposition of effects.

  [show abstract] [hide abstract]
  ABSTRACT: This paper investigates the relationship between general consumer confidence in the safety of food and consumer trust in institutions and organizations. More specifically, using a decompositional regression analysis approach, the extent to which the strength of the relationship between trust and general confidence is dependent upon a particular food chain actor (for example, food manufacturers) is assessed. In addition, the impact of specific subdimensions of trust, such as openness, on consumer confidence are analyzed, as well as interaction effects of actors and subdimensions of trust. The results confirm previous findings, which indicate that a higher level of trust is associated with a higher level of confidence. However, the results from the current study extend on previous findings by disentangling the effects that determine the strength of this relationship into specific components associated with the different actors, the different trust dimensions, and specific combinations of actors and trust dimensions. The results show that trust in food manufacturers influences general confidence more than trust in other food chain actors, and that care is the most important trust dimension. However, the contribution of a particular trust dimension in enhancing general confidence is actor-specific, suggesting that different actors should focus on different trust dimensions when the purpose is to enhance consumer confidence in food safety. Implications for the development of communication strategies that are designed to regain or maintain consumer confidence in the safety of food are discussed.

  Article: Consumer evaluations of food risk management quality in Europe.

  [show abstract] [hide abstract]
  ABSTRACT: In developing and implementing appropriate food risk management strategies, it is important to understand how consumers evaluate the quality of food risk management practices. The aim of this study is to model the underlying psychological factors influencing consumer evaluations of food risk management quality using structural equation modeling techniques (SEM), and to examine the extent to which the influence of these factors is country-specific (comparing respondents from Denmark, Germany, Greece, Slovenia, and the United Kingdom). A survey was developed to model the factors that drive consumer evaluations of food risk management practices and their relative importance (n= 2,533 total respondents). The measurement scales included in the structural model were configurally and metrically invariant across countries. Results show that some factors appear to drive perceptions of effective food risk management in all the countries studied, such as proactive consumer protection, which was positively related to consumers' evaluation of food risk management quality, while opaque and reactive risk management was negatively related to perceived food risk management quality. Other factors appeared to apply only in certain countries. For example, skepticism in risk assessment and communication practices was negatively related to food risk management quality, particularly so in the UK. Expertise of food risk managers appeared to be a key factor in consumers' evaluation of food risk management quality in some countries. However, trust in the honesty of food risk managers did not have a significant effect on food risk management quality. From the results, policy implications for food risk management are discussed and important directions for future research are identified.

• Article: Consumer acceptance of technology-based food innovations: lessons for the future of nutrigenomics.

  A Ronteltap, J C M van Trijp, R J Renes, L J Frewer
  [show abstract] [hide abstract]
  ABSTRACT: Determinants of consumer adoption of innovations have been studied from different angles and from the perspectives of various disciplines. In the food area, the literature is dominated by a focus on consumer concern. This paper reviews previous research into acceptance of technology-based innovation from both inside and outside the food domain, extracts key learnings from this literature and integrates them into a new conceptual framework for consumer acceptance of technology-based food innovations. The framework distinguishes 'distal' and 'proximal' determinants of acceptance. Distal factors (characteristics of the innovation, the consumer and the social system) influence consumers' intention to accept an innovation through proximal factors (perceived cost/benefit considerations, perceptions of risk and uncertainty, social norm and perceived behavioural control). The framework's application as a tool to anticipate consumer reaction to future innovations is illustrated for an actual technology-based innovation in food science, nutrigenomics (the interaction between nutrition and human genetics).

  [show abstract] [hide abstract]
  ABSTRACT: There are considerable uncertainties regarding how stakeholder engagement should be enacted. The lack of clear guidelines on good practice is arguably a consequence of an absence of evaluations on the effectiveness of past engagement exercises. Here we describe the evaluation of one engagement event concerning food risk management. This event involved presenting a novel food risk analysis model to key stakeholders in two workshops (in 2005 and 2007) in order to gather opinions and to consider the model’s likely impact on the wider community. The workshops and their evaluation, using elements of a previously developed evaluation framework, are described. The discussion emphasises how the organisers utilised the first evaluation report in order to improve the subsequent workshop. In the concluding section, the merits of both the engagement process and the methods used to evaluate it are discussed. Broader lessons for the academic, practitioner and policy communities are developed
