Optimised dispersion protocol for particle size measurement of copper oxides applied as feed additives and plant protection products
distribution to assess whether a nano-specific risk assessment should be performed. To measure the particle size distribution using electron microscopy (EM), a dispersion protocol that aims at maximal ...
Implementation of METROFOOD services in the Belgium node
tested for performance and high-quality service provision, and (e) sufficiently valorized. METROFOOD- FED. BE services will be made available for Open Access to external target users and stakeholders via ...
Development of a shotgun metagenomics workflow for the comprehensive surveillance of biological impurities in vitamin-containing food products
a novel bioinformatics pipeline, MetaCARP, compatible with short and long reads, enabling species-level identification and GMM detection. Workflow performance was evaluated using vitamin-containing food ...
Physicochemical characterization and genotoxicity assessment of nanomaterials using new approach methodologies
technique will be developed. This research is performed under the NAMS4NANO action via funding from the European Union through a grant of the European Food Safety Authority (agreement GP / EFSA / MESE ...
An interlaboratory proficiency test using metagenomic sequencing as a diagnostic tool for the detection of RNA viruses in swine fecal material.
sequencing (mNGS) can serve as a generic molecular diagnostic tool. An mNGS proficiency test (PT) was performed in six European veterinary and public health laboratories to detect porcine astroviruses in fecal ...
Per- and polyfluoroalkyl substances in food and beverages: determination by LC-HRMS and occurrence in products from the Belgian market.
population. More than a decade ago, such assessment was performed only for PFOS and PFOA and is currently outdated. For the determination of PFAS in foodstuffs, an extraction based on a “quick, easy, cheap, ...
FT-IR spectroscopy as a rapid method for Salmonella spp. typing
within serogroup O:4 would require more in-depth analysis to increase the performance. S. Infantis and S. Enteritidis, being the only representatives of the O:7 and O:9 serogroup respectively, do not allow ...
Reflections of the NRL: implementation of EN ISO 11133 in food microbiology laboratories
11133 food microbiology laboratories Quality Abstract: Microbiology testing is critical to guarantee food safety and quality. Laboratories performing these tests are required to deliver accurate and ...
Validation of the measurement of Aluminium in food by ICP-OES after acid digestion
ICP- OES was performed, during which the precision, trueness and quantification limits (LOQ) of the measurement were determined. An expanded measurement uncertainty could be calculated. Keywords: ...
Strain-level characterization without culture enrichment? Easing and accelerating outbreak investigation using shotgun metagenomics facilitated with nanopore adaptive sampling
adaptive sampling, following whole genome amplification to increase the amount of genetic material to meet sequencing standards. The strain-level data analysis was performed as previously described (Buytaers ...
