Strain-level characterization without culture enrichment? Easing and accelerating outbreak investigation using shotgun metagenomics facilitated with nanopore adaptive sampling
various living organisms or the cultivation parameters. Moreover, the current methods require a subsequent but not always successful isolation. In part due to these two drawbacks, not all outbreaks can be ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
sample preparation methods allowed to obtain a full characterization to strain level of the spiked strain in the beef sample, carrying another non-pathogenic strain of E.coli. The simplest protocol was ...
Targeted High-Throughput Sequencing Enables the Detection of Single Nucleotide Variations in CRISPR/Cas9 Gene-Edited Organisms
analytical and interpretation levels since this requires methodological approaches that can target and detect a specific single nucleotide variation (SNV) introduced into a GE organism. In this study, we ...
Development of a reliable UHPLC-MS/MS method for simultaneous determination of zearalenone and zearalenone-14-glucoside in various feed products
impurities and enriching the target analytes in different feeds. The critical parameters affecting the performance of the solid-phase extraction (SPE) procedure were carefully optimized, and 20% acetonitrile ...
Development, Validation and Application of a Targeted LC-MS Method for Quantification of Microcystins and Nodularin: Towards a Better Characterization of Drinking Water
well-functioning society. However, due to climate change and pollution, access to safe freshwater sources diminishes. Increasing salinization, increasing sea levels and the presence of organic and non-organic ...
A Targeted UHPLC-MS/MS Method Validated for the Quantification of Ergot Alkaloids in Cereal-Based Baby Food from the Belgian Market
12 ergot alkaloids, would be non-conforming to the newly proposed Maximum Residue Level (MRL). Health Topics: Food consumption and food safety Consommation et sécurité alimentaires Voedselconsumptie ...
Organisation of Multi-Mycotoxin Proficiency Tests: Evaluation of the Performances of the Laboratories Using the Triple A Rating Approach
targeted in the 2 matrices. The triple A rating seems to be appropriate in evaluating the performances of laboratories involved in multi-mycotoxin analyses. Accredited and non-accredited analytical methods ...
Retrospective survey of unauthorized genetically modified bacteria harbouring antimicrobial resistance genes in feed additive vitamin B2 commercialized in Belgium: Challenges and solutions
allowing to provide a first picture of GM bacterial contaminations. It consisted in a first-line screening strategy gathering available PCR-based methods targeting both the B. subtilis species, frequently ...
Food Chemistry, Function and AnalysisDNA Techniques to Verify Food Authenticity CHAPTER 8. GMO Detection and Identification Using Next-generation Sequencing
feasibility in supporting the current genetically modified organism (GMO) routine detection systems for unauthorized GMO. Depending upon the specific samples under investigation, two categories of NGS ...
Development and Validation of a UHPLC-ESI-MS/MS Method for Quantification of Oleandrin and Other Cardiac Glycosides and Evaluation of Their Levels in Herbs and Spices from the Belgian Market
develop a targeted analytical method utilizing liquid chromatography—tandem mass spectrometry (LC- MS / MS) for quantification of these plant toxins in a herbal-based food and human urine. The method ...
