    Abstract The use and application possibilities of the multi-criteria decision analysis (MCDA) methodology, as a decision support tool in food safety risk management was demonstrated in a case study on the washing of minimally processed leafy greens, a multidimensional food safety decision problem involving public health, economic, environmental and socio-cultural aspects. The washing procedure remains a critical step in the production chain of ready-to-eat leafy vegetables, as the process water could act as a vector for cross-contamination of pathogens. The use of chemical sanitizers in produce wash water is scattered over EU member states and regulations remain unharmonized. The most appropriate washing methodology was determined, for the Belgian situation, based on an evaluation of weighted criteria, following the PROMETHEE II algorithm. Hereto multiple sources of information were consulted, including scientific and grey literature, expert evaluations and information provided by vegetable processing companies. Data generated over the past 10 years and published in scientific literature were selected and aggregated into probabilistic distributions using @Risk® software. An online stakeholder consultation, organized in Belgium, had the aim to measure stakeholders' preferences. The MCDA case study indicated that washing leafy greens in potable (ice) water, should be considered the most appropriate method for the Belgian case. The MCDA methodology can be applied for building evidence-based risk management decisions in the field of food safety, as it provides a transparent framework for the collection of evidence and the inclusion of stakeholders' interests.

    Abstract The current society consists of an increasing number of people vulnerable to infections. For certain people with severe immunodeficiency, a neutropenic or low-microbial diet is being prescribed, which substitutes high-risk foods that are more likely to contain human (opportunistic) pathogens with lower-risk alternatives. These neutropenic dietary guidelines are typically set up from a clinical and nutritional perspective, rather than from a food processing and food preservation perspective. In this study, the current guidelines in use by the Ghent University Hospital were evaluated based on the current knowledge of food processing and preservation technologies and the scientific evidence on microbiological quality, safety, and hygiene of processed foods. Three criteria are identified to be important: (1) the microbial contamination level and composition; (2) the potential presence of established foodborne pathogens such as

  3. Article: Evaluation of B. thuringiensis-based biopesticides in the primary production of fresh produce as a food safety hazard and risk

    Abstract B. thuringiensis is a naturally occurring insect pathogen, genetically closely related to the human pathogen B. cereus. Commercial B. thuringiensis biopesticides have a long track record of safe use. Still, concerns are raised on the potential for enterotoxin production by biopesticide strains, especially since B. thuringiensis found in salad was a hypothesized cause of a foodborne outbreak in the EU.This review uses the basic steps of a risk assessment to collect available knowledge relevant to B. thuringiensis biopesticides and their impact on food safety of fresh produce. Subsequently, some directions for effective risk management strategies are provided, reflecting on various aspects that might impact decision-making on the use of B. thuringiensis as a biopesticide.Phylogenetic studies show that B. thuringiensis biopesticide strains are part of another clade compared to highly pathogenic B. cereus group strains. Although they contain enterotoxin genes, their ability to produce these toxins in the human gastrointestinal tract may be more limited. Furthermore, surveys show that it is unlikely to find elevated levels of B. thuringiensis on ready-to-eat fresh produce, higher than the established action limit of 10⁵ CFU/g for presumptive B. cereus on foods. Finally, the B. cereus diarrheal syndrome is generally mild and self-limiting. Therefore, the use of B. thuringiensis biopesticides is expected to pose a low food safety risk.

    Abstract Background: Sport-for-All emphasizes that every individual has the right to participate in sport. Despite all efforts to deliver Sport-for-All during the past decades, studies indicate that sport participation rates have been stagnating, whereas social inequalities in sport continue to exist. By applying an institutional theory lens, this study sheds light on how the dual mission of sport federations, i.e., providing Sport-for-All and high performance sport, affects the Sport-for-All projects of Flemish sport federations (e.g., amount of projects and target groups). In particular, Sport-for-All projects have to reduce barriers to engage in the sport system and be supported by a sport federation. Furthermore, this study seeks to better understand the impact of the underlying institutional logic on the institutional pressure and legitimacy of the sport federations.
    Method: This study implemented a cross-sectional field study in sport federations. In particular, the sport federations selected for our study are the 47 Flemish sport federations. Both qualitative (i.e., document analysis) and quantitative research methods (i.e., a new questionnaire was developed based on institutional theory) were applied in the study.
    Results: Results indicated that sport federations are important partners in support of Sport-for-All projects, but also suggested that there is a discrepancy between the projects of the high performance-oriented and the Sport-for-All-oriented federations. Specifically, the high performance-oriented federations were targeting youth participants, whereas Sport-for-all-oriented federations aimed to reach disadvantaged groups. Furthermore, the results indicated that high performance-oriented federations endured more institutional pressure than Sport-for-All-oriented federations.
    Conclusion: The results of our study indicated that the Sport-for-All projects of performance-oriented federations are often more superficial compared to Sport-for-All oriented federations, and that the latter federations play an important role in attaining public health targets. Moreover, policymakers should consider how they can optimize the role of the performance-oriented federations in the Sport-for-All delivery (e.g., they could function as a bridge to guide participants who prefer a less competitive setting towards Sport-for-All oriented federations).
