Identification and characterization of inorganic food additives and pearlescent pigments in sprays for food decoration by STEM-EDX
control laboratories and only limited guidance is currently available3. This study developed electron microscopy-based methods to identify and characterize the particles of individual components in eight ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
Ultimately, a validation of the method is still necessary in order to obtain a precise limit of detection based on the analysis of a large dataset of samples. Moreover, other technologies can still be ...
ESCAIDE 2022 Oral presentation: International outbreak of Salmonella Typhimurium linked to a chocolate factory in 2022: Belgian findings
investigations indicated two clusters: HC5_296366 (cluster 1) and HC5_298160 (cluster 2). We assessed the extent of the outbreak in Belgium and took measures to limit further spread. Methods Probable and ...
Shotgun metagenomics as a ONE Health tool for better protecting human health
composing genes such as virulence or antimicrobial resistance (AMR) genes, without prior knowledge, nor the need to isolate. Such approaches could offer efficient and fast solutions to limitations faced by ...
Development of a genoserotyping system for the identification of Salmonella serotypes
(EU regulation N°2160/2003, Belgian royal decree 27/04/2007 and Belgian FASFC note BP- MN- FDS / LABO /1557457 v8), with the aim to limit their transmission to humans. Unfortunately, the classical ...
Open Lab Application for the Characterization of Nanomaterials by Transmission Electron Microscopy
dedicated infrastructures remain limited to specialized research institutions. Over the last years the National Reference Laboratory for Nanomaterials in Food of Sciensano (Belgium) has acquired high level ...
Study of the possible migration risks of food contact materials for children under 3 years
migration limits) showed that for some baby bottles, several not authorised compounds exceeded the generally adapted “no-detection limit” of 10 µg kg-1. Substances, such as 2,4-di-tertbutylphenol (up to 118 ...
Proteomic detection as an alternative for the quantification of Staphylococcus aureus enterotoxins
existence of the toxins in foods and immunoassays are not specific enough, not suitable for quantification and more importantly limited in the range of toxins they can identify. The proteomic approach method ...
Design of multiplex assays for molecular subtyping of pathogens with the Luminex xMAP technology
IT limitation Limitations Luminex microorganism microorganisms Molecular molecular subtyping Multiplex assay Oligonucleotides outbreak outbreaks pathogen reducing regulation Sample SOFTWARE specificity ...
Food contamination with pyrrolizidine alkaloids: the expected and the unexpected
Several steps were carefully optimized for each targeted food matrices with a specific focus on very low limits of quantification (LOQ s < 1 ng/g or ng/mL), taking into account the various interfering ...
