Update of the risk assessment of nickel in food and drinking water

per day was selected as the reference point for the establishment of a tolerable daily intake (TDI) of 13 μg/kg bw. Eczematous flare‐up reactions in the skin elicited in nickel‐sensitised humans, ...

Risk assessment of glycoalkaloids in feed and food, in particular in potatoes and potato‐derived products

a lowest‐observed‐adverse‐effect level of 1 mg total potato GA s/kg body weight (bw) per day as a reference point for the risk characterisation following acute exposure. In humans, no evidence of health problems associated with ...

A Practical Method to Implement Strain-Level Metagenomics-Based Foodborne Outbreak Investigation and Source Tracking in Routine.

often time-consuming and not always successful. Therefore, we aimed to improve outbreak investigation by developing a method that can be implemented in reference laboratories to characterize the pathogen ...

Use of Whole Genome Sequencing Data for a First in Silico Specificity Evaluation of the RT-qPCR Assays Used for SARS-CoV-2 Detection.

reference genome and 2624 closely related other respiratory viral genomes. The specificity of the assays was generally good and stable over time. An exception is the first method developed by the China Center ...

The Benefits of Whole Genome Sequencing for Foodborne Outbreak Investigation from the Perspective of a National Reference Laboratory in a Smaller Country.

National Reference Laboratories of smaller countries often show slower uptake of WGS, mainly because of significant investments required to generate and analyze data of a limited amount of samples. To ...

PT-2020-NRL-TE-FASFC “Determination of As, Cd, Pb and Hg in food supplements"

Keywords: proficiency test Trace Elements Abstract: From the 1st of January 2008, the laboratory for Trace Elements at Sciensano (former CODA- CERVA), Tervuren, operates as National Reference Laboratory for ...

NAuRA: Genomic Tool to Identify Staphylococcal Enterotoxins in Strains Responsible for FoodBorne Outbreaks.

strains responsible for outbreaks in Europe as well as the RefSeq reference database. Based on phylogenetic inference performed using maximum-likelihood on the core genomes of the strains in this ...

Characterization of Nanoparticles: Measurement Processes for Nanoparticles: Characterization of nanomaterials by transmission electron microscopy: Measurement procedures

measurement. The results of published inter-laboratory comparisons are referred to, along with the availability of reference materials necessary for instrument calibration and method validation. The application ...

Risk assessment of chlorinated paraffins in feed and food

Panel selected as reference points a BMDL10  of 2.3 mg/kg bw per day for increased incidence of nephritis in male rats, and of 36 mg/kg bw per day for increased relative kidney weights in male and female rats for ...

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

Second, an in-house database, with 16S reference sequences from bacteria producing FE, was constructed for their fast identification through blast analysis. Third, the sensitivity was assessed on a spiked ...
