Retrospective surveillance of viable Bacillus cereus group contaminations in commercial food and feed vitamin B2 products sold on the Belgian market using whole-genome sequencing
Viable B. cereus was identified in 18 of the 75 (24%) tested products, resulting in 36 WGS datasets, which were classified into eleven different ST s, with ST165 (n = 10) and ST32 (n = 8) being the most ...
BSFM 2023- L. monocytogenes in Plant-Based Foods: insights from of a recent foodborne outbreak linked to vegan alternative to cheese
plant-based food production. For example, challenge tests performed on bovine milk and plant-based milk demonstrated similar growth of L. monocytogenes. The outbreak described here provides strong evidence of ...
Strain-level characterization without culture enrichment? Easing and accelerating outbreak investigation using shotgun metagenomics facilitated with nanopore adaptive sampling
outbreak. Additionally, the living S. aureus strain was spiked into mashed potatoes at a level of 10 5 CFU per 25 grams and three DNA extraction kits were tested, in combination with two databases for ...
EFSA Project on the use of New Approach Methodologies (NAMs) for the hazard assessment of nanofibres. Lot 1, nanocellulose oral exposure: gastrointestinal digestion, nanofibres uptake and local effects
submitted to a thorough physicochemical characterisation. A battery of in vitro tests was used to provide insight into NC hazard and mode of action according to a tiered approach, which lead to selection of ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
It was proven that whole genome sequencing has a higher resolution than any combination of tests carried out so far. But the isolation is not always possible, and it is time-consuming. A new method ...
Comparison of 6 DNA extraction methods for isolation of high yield of high molecular weight DNA suitable for shotgun metagenomics Nanopore sequencing to detect bacteriaAbstractBackgroundResultsConclusion
on-site application. In addition to the comparison of the quality, quantity and purity of the extracted DNA, the performance obtained when doing Nanopore sequencing on a MinION flow cell was also tested ...

Methodological choices in brucellosis burden of disease assessments: A systematic review
Most studies retrieved brucellosis epidemiological data from administrative registries. Incidence data were often estimated on the basis of laboratory-confirmed tests. Not all studies included mortality ...
How theory can help to understand the potential impact of food environment policies on socioeconomic inequalities in diet: an application of Bourdieu's capital theory and the scarcity theory.
on the mechanisms underlying socioeconomic inequalities in health can help to guide future empirical studies in testing theory-based hypotheses on differential effects of policies, and thereby enhance ...
