The effect of a shelf placement intervention on sales of healthier and less healthy breakfast cereals in supermarkets: A co-designed pilot study.
category (breakfast cereals), was selected for testing. A pilot study (baseline, intervention and follow-up, 12-weeks each) was undertaken in six supermarkets (three intervention and three control) in ...
Development of a genoserotyping system for the identification of Salmonella serotypes
biochemical test. From this molecular markers’ selection, 4 MOL- PCR assays were developed, i.e. the molecular markers were recognized by probes through a ligation-amplification reaction (MOL- PCR), followed by ...
Molecular Subtyping of Salmonella Typhimurium with Multiplex Oligonucleotide Ligation-PCR (MOL-PCR).
oligonucleotide ligation reaction for detection of the molecular marker, followed by a singleplex PCR for signal amplification and analysis of the MOL- PCR products on a Luminex platform. This last step occurs ...

Belgian Campylobacter European Follow up FOLLOW-UP ON study Workshop Health Topics: Food consumption and food safety Consommation et sécurité alimentaires Voedselconsumptie en –veiligheid Service: ...
A two-step lyssavirus real-time polymerase chain reaction using degenerate primers with superior sensitivity to the fluorescent antigen test.
culture infectious dose. The related vesicular stomatitis virus was not recognized, confirming the selectivity for lyssaviruses. The assay was applied to follow the evolution of rabies virus infection in ...
Determination of caramel colorants' by-products in liquid foods by ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).
the concentration range expected in the type of foods targeted. For the determination of the imidazole substitutes (THI, 2- and 4- MI), a sample enrichment and clean-up step by strong cation solid-phase ...
Multi-dye residue analysis of triarylmethane, xanthene, phenothiazine and phenoxazine dyes in fish tissues by ultra-performance liquid chromatography-tandem mass spectrometry.
ultra-performance liquid chromatography-tandem mass spectrometry. Samples were extracted with acetonitrile, followed by an oxidation step using 2,3-dichloro-5,6-dicyanobenzoquinone. Further clean-up was performed by ...
