Development of novel analytical methods to trace small micro- and nanoplastics in food matrices
a diameter smaller 1 µm, called nanoplastics (NP s) that could be found in food matrices and environmental samples, by means of specific measurement techniques. Therefore, the aim of this work is to develop ...
EFSA Project on the use of New Approach Methodologies (NAMs) for the hazard assessment of nanofibres. Lot 1, nanocellulose oral exposure: gastrointestinal digestion, nanofibres uptake and local effects
(iii) assessment of any digestion or degradation of NC by the human microbiome. Eight NC samples belonging to the three NC types, plus a comparator in the micro-range, were selected as study materials and ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
based on the sequencing of all genetic material of the sample without isolation has become available some years ago, e.g. shotgun metagenomics. It allows to get a screenshot of every microbiological ...
Comparison of 6 DNA extraction methods for isolation of high yield of high molecular weight DNA suitable for shotgun metagenomics Nanopore sequencing to detect bacteriaAbstractBackgroundResultsConclusion
must be able to isolate pure high molecular weight (HMW) DNA from complex metagenomics samples, without introducing any bias. New methods released on the market, and protocols developed at the research ...
Report on initial findings of on-site diagnostic tests and IT solutions for human clinical, veterinary and environmental samples for early warning of emerging resistant pathogens
Publication Type: Sci. report, recommendat°, guidance doc., directive, monograph Authors: Manal AbuOun; Indre Navickaite; Thomas I. Wilkes; Marco Di Domenico; Giuliano Garofolo; Bram Bloemen; Mathieu Gand; Nancy Roosens; Kevin Vanneste; Sigrid C.J. De Kee ...
Migration of mineral oil from cardboard packaging for food: Identification of the hazards and assessment of the exposure of the Belgian population
The detected MOSH and MOAH concentrations were then compared to the action thresholds set by the Scientific Committee (SciCom) of the Belgian Food Safety Agency (FASFC) in 2017. Only one sample exceeded ...
Nanomaterials for food applications: Analytical challenges and practical solutions for enforcing labeling of nanoingredients in food products in the European Union
“nano” labeling poses several analytical challenges. This includes the many potential sources of NP s in food which can interfere with the analysis, the challenges in relation to sample preparation, the ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
BPB, BPF, and BPS) and two alkylphenols (nonyl phenol (NP) and tert-octylphenol (OP) in human placenta samples. After a short sample preparation time the extracts are analysed by UHPLC- MS / MS using ...
Comparison of SNP-based subtyping workflows for bacterial isolates using WGS data, applied to Salmonella enterica serotype Typhimurium and serotype 1,4,[5],12:i:.
including five isolates from a confirmed outbreak and three isolates obtained from the same patient at different time points. The analysis was carried out using the original (high-coverage) and a down-sampled ...
Biological activity conferred by endocrine disrupting chemicals in hospital effluent and river water from the Brussels Region, Belgium
assess endocrine activity by comparing the mixture or cocktail effect originating from the sample extract. Added value is that this technique picks up effects from compounds that are not ...
