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

bacterium that occurs as a contaminant in food and feed, occasionally resulting in food poisoning through the production of various toxins. In this study, we retrospectively characterized viable B. cereus ...

Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety

the host depletion DNA extraction method. We then investigated the issue of the detection and characterization of genetically modified microorganisms (GMM s) in microbial fermentation products as a case ...

Targeted High-Throughput Sequencing Enables the Detection of Single Nucleotide Variations in CRISPR/Cas9 Gene-Edited Organisms

and their derived food/feed products commercialized on the European Union market fall within the scope of European Union Directive 2001/18/ EC. Consequently, their control in the food/feed chain by GMO ...

LC-MS/MS Validation and Quantification of Cyanotoxins in Algal Food Supplements from the Belgium Market and Their Molecular Origins

worldwide. However, harmful natural compounds can contaminate these products. In the case of algae-based products, the presence of toxin-producing cyanobacteria may cause health risks. However, data about the ...

Development of a taxon-specific real-time PCR method targeting the Bacillus subtilis group to strengthen the control of genetically modified bacteria in fermentation products

fermentation products, such as enzymes, additives and flavorings, belong to the  Bacillus subtilis  group. Recently, unexpected contaminations with unauthorized genetically modified (GM) bacteria (viable cells ...

Shotgun metagenomics as a ONE Health tool for better protecting human health

identify all biological material in a sample without a priori knowing what to look for, could transform the way specific key public health questions can be addressed, in a ONE Health context. Metagenomics is ...

Listeria monocytogenes isolates from Cornu aspersum snails: Whole genome-based characterization and host-pathogen interactions in a snail infection model.

infection model showed that hypervirulent isolates triggered programmed host cell death pathway by increasing up to 30% the circulating apoptotic hemocytes in combination with induced nitrate production and ...

Development of a real-time PCR marker targeting a new unauthorized genetically modified microorganism producing protease identified by DNA walking

DNA walking analysis was performed on a protease product suspected to contain a new unauthorized genetically modified microorganism (GMM). Though the characterization of unnatural associations of ...

Adjunct Culture of Non-Starter Lactic Acid Bacteria for the Production of Provola Dei Nebrodi PDO Cheese: In Vitro Screening and Pilot-Scale Cheese-Making.

enzymatic activities, suitable as adjunct culture for the Provola dei Nebrodi cheese production. One hundred and twenty-one lactic acid bacteria, isolated from traditional Provola dei Nebrodi cheese samples, ...
