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
indications for genotoxicity were obtained. Finally, no formation of smaller particles following colonic fermentation of NC was observed. For the integration of these results in regulatory hazard assessment of ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
the STEC strain from the endogenous E.coli strains while an Illumina MiSeq run takes 48 hours. Moreover, the lower-cost Flongle flow cell showed the same results after 24 hours of sequencing when using ...
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
level, were specifically designed for this application and need to be assessed. Results: In this study, with different bacterial cocktail mixes, analyzed as pure or spiked in a synthetic fecal matrix, we ...
Migration of mineral oil from cardboard packaging for food: Identification of the hazards and assessment of the exposure of the Belgian population
Next, the dietary exposure of the Belgian population to mineral oil was assessed by combining the analytical results with consumption data of the Belgian Food Consumption Survey. Overall, the exposure to ...
Simultaneous determination of parabens, bisphenols and alkylphenols in human placenta by ultra-high performance liquid chromatography- tandem mass spectrometry
0.6-2.1 ng g−1 for BPF and from 0.8-1.3 ng g−1 for BPS. BPB and NP were not detected and OP levels ranged from 0.5-3.7 ng g−1. The results demonstrate that the developed analytical method is very sensitive ...
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:.
modifications of the existing workflows were also tested. This allowed us to propose data analysis schemes most suitable for routine SNP-based subtyping applied to S. Typhimurium and S. 1,4,[5],12:i:-. Results ...
Biological activity conferred by endocrine disrupting chemicals in hospital effluent and river water from the Brussels Region, Belgium
hospital effluent and, respectively, 52.3 and 1.2ng EEQ /L for WWTP influent and effluent. For comparison reasons, commercial drinking waters amount to 0.004-0.070 ng EEQ /L. These results indicate that ...
In vitro model to study the endocrine disrupting activity of migration products from plastic food contact materials
replacing polycarbonate, that are used on the Belgian market, it resulted in the conclusion that polymers used for the manufacture of baby bottles are mainly polypropylene, polyethersulfone, silicone, ...
