Method development for analysis of nanoplastics in drinking water and milk using transmission electron microscopy (TEM)
risk assessment. This TEM-based approach was validated using polystyrene (PS) reference beads in the size range 60-500 nm, encompassing all analysis steps, from sample preparation to image analysis. Typically, the ...
Dietary exposure of Sorbates (E 200 – 202) and Benzoates (E 210 – 213) for the Belgian population
(EC) No 1333/2008 requires the Member States to monitor the consumption and use of FA s using a risk-based approach and communicate the results to the European Commission and the National authorities. ...
Spectroscopic approaches for conformity analysis of e-liquids
legislation, was also taken into account of this study, due to its popularity. In this study spectroscopic approaches were explored to check the label conformity for nicotine and the presence of caffeine, ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
bivalve). These samples were not enriched as it is particularly arduous to culture these viruses in laboratory conditions. Because the contamination level was low in a complex matrix, we tested several sample ...
Identification of Mycobacterium abscessus Subspecies by MALDI-TOF Mass Spectrometry and Machine Learning.
J Clin Microbiol, Volume 61, Issue 1 (2023) Keywords: Humans Mycobacterium Mycobacterium abscessus Mycobacterium Infections, Nontuberculous Nontuberculous Mycobacteria Spectrometry, Mass, Matrix ...
Targeted LC-MS/MS combined with multilocus DNA metabarcoding as a combinatory approach to determine the amount and the source of pyrrolizidine alkaloids contamination in popular cooking herbs, seeds, spices and leafy vegetables.
levels. As a proof of concept, multilocus DNA metabarcoding was performed on six highly contaminated samples, belonging to each subtype matrix, containing high levels of heliotrine type of PA / PANO s. Each ...
Clinical Origin and Species Distribution of spp. Isolates Identified by Molecular Sequencing and Mass Spectrometry: A European Multicenter Hospital Prospective Study.
to allow a fast, accurate and free-access identification of fungi by matrix-assisted laser desorption ionization-time of flight (MALDI- TOF) mass spectrometry. Taking advantage of the MSI database user ...

multilocus DNA metabarcoding was performed on six highly contaminated samples, belonging to each subtype matrix, containing high levels of heliotrine type of PA / PANO s. Each time the analysis demonstrated ...
Strain-Level Metagenomic Data Analysis of Enriched In Vitro and In Silico Spiked Food Samples: Paving the Way towards a Culture-Free Foodborne Outbreak Investigation Using STEC as a Case Study.
successful foodborne outbreak investigation using a metagenomic approach, it is, however, necessary to bioinformatically separate the genomes of individual strains, including strains belonging to the same ...
A Practical Method to Implement Strain-Level Metagenomics-Based Foodborne Outbreak Investigation and Source Tracking in Routine.
outbreak depends on the rapid and accurate identification of the responsible food source. Conventional methods based on isolation of the pathogen from the food matrix and target-specific real-time polymerase ...
