Physico-chemical characterisation of the fraction of silver (nano)particles in pristine food additive E174 and in E174-containing confectionery.

is a specific concern for the E174 risk assessment. This study characterised the fraction of silver (nano)particles in 10 commercially available pristine E174 food additives and 10 E174-containing ...

Chemical and toxciological characterization of e-liquid cigarettes

information on their genotoxicity was present. For four of these flavourings, a commercial standard was available and thus could be tested in vitro using an Ames- and micronucleus test. One of the four ...

Bénédicte Source: Emerging Infectious Diseases, Volume 26, Issue 8 (2020) Abstract: In 2019, an outbreak of avian influenza (H3N1) virus infection occurred among commercial poultry in Belgium. Full-genome ...

The African swine fever virus isolate Belgium 2018/1 shows high virulence in European wild boar.

viral genome were also detected in genitals and accessory sex glands of two boars. There were no antibodies detectable in commercial antibody ELISA s, antibody LFD s and indirect immunoperoxidase tests. ...

Selection of a Noninvasive Source of Human DNA Envisaging Genotyping Assays in Epidemiological Studies: Urine or Saliva?

Genomic DNA was extracted using commercial kits. Quantitative and qualitative evaluation was done by assessing the yield, the purity, and integrity of the extracted DNA. As a proof-of-concept, genotyping ...

Strategy for the identification of micro-organisms producing food and feed products: Bacteria producing food enzymes as study case

regulations require safety assessments of food enzymes (FE) before their commercialization. FE are mainly produced by micro-organisms, whose viable strains nor associated DNA can be present in the final ...

Detection strategy targeting a chloramphenicol resistance gene from genetically modified bacteria in food and feed products

resistance (AMR) genes as selection markers, are frequently used to produce food and feed enzymes, additives and flavourings. Such commercialized microbial fermentation products should not contain GMM, or ...

Genotoxic evaluation of the liquids present in electronic cigarettes

European CH emicals Agency. In a next step, compounds for which no data were found and that were commercially available were studied in the Ames test and the in vitro micronucleus test (i.e. b-phellandrene, ...

Batch release of vaccines in Europe: from method transfer to first commercial batch available on the market. Straightforward approach that requires a proactive mindset of the manufacturer.

a lengthy process. Sometimes more than one year should be taken into account between the intention of putting a vaccine on the market and the first available commercial batch. Since OCABR in EU is obligatory, ...
