Multi-dye residue analysis of triarylmethane, xanthene, phenothiazine and phenoxazine dyes in fish tissues by ultra-performance liquid chromatography-tandem mass spectrometry.
the European Union and scientific literature. Good linearity (R ≥0.99 and goodness-of-fit (g) ≤10%) was achieved over the tested concentration range (0.25-2ngg(-1)). Limit of quantification was ...
Predicted dietary intake of selenium by the general adult population in Belgium.
people. The largest selenium concentrations (>1 mg kg(-1)) were found in Brazil nuts and offal, of which the consumption is limited. Usually consumed food groups with the highest selenium concentrations ...
Development and validation of qualitative SYBR®Green real-time PCR for detection and discrimination of Listeria spp. and Listeria monocytogenes.
of Listeria spp. The selected primers were designed to amplify short fragments (60 to 103 bp) in order to obtain optimal PCR efficiency (between 97 and 107 % efficiency). The limit of detection of the ...
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 ...
Fortification of bread with iodized salt corrected iodine deficiency in school-aged children, but not in their mothers: a national cross-sectional survey in Belgium.
should not be limited to children, but should be extended to women of child-bearing age. Health Topics: Food consumption and food safety Category: A1 FOS Classification: 3.03 Health sciences ...
Prevalence and levels of Bacillus cereus emetic toxin in rice dishes randomly collected from restaurants and comparison with the levels measured in a recent foodborne outbreak.

Follow-up of the Bacillus cereus emetic toxin production in penne pasta under household conditions using liquid chromatography coupled with mass spectrometry.
temperature as 4 °C did not allow any detectable cereulide production for any of the two tested strains. At the limited temperature abuse of 8 °C, a detectable amount of cereulide was observed after two days ...
Rapid method for the confirmatory analysis of chrysoidine in aquaculture products by ultra-performance liquid chromatography-tandem mass spectrometry.
water and an acetonitrile gradient within 6 min. Mass spectrometric analysis was performed in the positive electrospray MS / MS mode. The limit of quantification was 0.25 ng/g, which was 30 times lower ...
A theoretical introduction to "combinatory SYBRGreen qPCR screening", a matrix-based approach for the detection of materials derived from genetically modified plants.
RoundUp Ready soy GTS40-3-2 as an example. By applying a limited set of SYBRGREEN qPCR methods and through application of a newly developed “prime number”-based algorithm, the nature of subsets of ...
Lessons learned from the management of a national outbreak of Salmonella ohio linked to pork meat processing and distribution.
clinical isolates caused self-limiting gastroenteritis; both genders (32 males and 28 females) and all age groups (three children <5 years of age, three children 5 to 14 years of age, 32 adults 15 to 64 ...
