MALDI-ToF workshop (food microbiology) in Oslo, Norway, on 5 June 2019

The workshop, which is arranged by NMKL, is not only useful for MALDI-ToF users but also for those who are considering to use MALDI-ToF in the future. It will focus on microbiology, however, there will be presentations about the general principles of MALDI-ToF, what is required, how to use it, how to expand the database, experience with usage and also presentations by the suppliers of the equipment.

New NordVal International certificate

Two NordVal International certificates issued to Biotecon have been renewed: NordVal International Certificate 023 "foodproof® Salmonella Detection Kit, Hybridization Probes and foodproof® Salmonella Detection Kit, 5’ Nuclease, in combination with foodproof® ShortPrep I Kit or foodproof® StarPrep One Kit” and  NordVal International Certificate 025 ”foodproof® Listeria monocytogenes Detection Kit, Hybridization Probes and foodproof® Listeria monocytogenes Detection Kit,  5’ Nuclease, in combination with foodproof® ShortPrep II Kit or foodproof® StarPrep Two Kit”.  Both methods are real-time PCR and use detection with specific, fluorescence labelled probes. The former is applicable for food, feed and environmental samples and the latter for food and environmental samples. See certificate No. 023 here and No. 025 here.

 

Two NordVal International certificates issued to Hyserve have been renewed: NordVal International Certificate 042 "Compact Dry X-SA Method for the Enumeration of Staphylococcus aureus in Foods" and NordVal International Certificate 043 ”Compact Dry YM Method for the Enumeration of Yeasts and Moulds in foods”. Compact Dry comprises ready-to-use dry media sheets with culture medium and a cold-soluble gelling agent, rehydrated by inoculating 1ml diluted sample into the centre of the self-diffusible medium. The Compact Dry X-SA and the Compact  Dry YM methods both contain chromogenic medium and selective agents for the detection and enumeration of Staphylococcus aureus or yeast and mould, respectively. See certificate No. 042 here and No. 043 here.

 

NordVal International Certificate 017 "Campylobacter real-time PCR” issued to Eurofins, has been renewed.
This real time PCR method is applicable for the detection of the human pathogenic thermotolerant Campylobacters  (C. jejuni, C. coli and C. lari) in chicken raw meat, cloacae swabs and faecal samples collected on disposable shoe covers in rearing houses. See the certificate here.

3rd edition of procedure on estimation and expression of measurement uncertainty in chemical analysis available in English

When the result of a chemical analysis is presented in an analytical report it is recommended that it should always be reported as a numerical result. For the result to be complete, the measurement uncertainty of the analysis should also be included. In many cases, a result can be very hard to interpret unless accompanied by its uncertainty.

In this updated version of the procedure, guidance on how to handle bias / systematic errors in relation to measurement uncertainty is included. The principles described in Nordtest TR 537 for environmental analyzes have been introduced in the NMKL procedure and examples showing how these calculations are to be performed have been added. Whether one can or should correct for systematic errors is a complex issue, and a new section has been added to explain his. Additionally, minor restructuration and update of references have been undertaken.

A scandinavian version of this 3rd edition will follow.

New method for determination of sodium by capillary electrophoresis in foodstuffs

NMKL method No. 203 describes the determination of sodium content in foodstuffs by capillary electrophoresis (CE). The CE method is quick and needs both very little sample handling and low amount of solvents. It is applicable to various matrices such as bread, vegetables and meat products. The salt content is calculated from the sodium content with the formula: salt = 2.5 x sodium.

Sodium is extracted from sample and analysed by CE with diode array detector. The minimum content of sodium that can be detected and quantified is 0.03 g/100 g.

International symposium in Norway in June 2019: Speeding towards -omics ...

Chemical and Microbiological Food Analyses

Don’t miss the opportunity to participate in this international symposium in Oslo, Norway, on 3-4 June 2019 arranged by AOAC Europe – NMKL – NordVal International.

The purpose of the symposium is to bring together scientists, technicians and companies to discuss emerging technologies and techniques with emphasis on recent advances and applications in food analyses.

The scope of this symposium is to discuss different aspects of use, validation and application of –omics related to food, but not only.

The topics are presented in plenum and in parallel sessions:

  • Genomics, proteomics, transcriptomics, metabolomics, foodomics
  • New rapid methods
  • Multi-methods
  • Hand-held instrumentation
  • Digitalization of the analytical process (from sampling to interpretation of results)

For programme see here.

Fees:
Registration, ordinary: 400 EUR
Registration, reduced for students: 200 EUR
Exhibitors: 1,600 EUR, covering facilities and registration for two persons

New deadline: 19 April 2019 or as long as there are free seats

New method for determination of isotope dilution in foodstuffs

NMKL method No. 202, "Methylmercury: determination by isotope dilution GC-ICPMS in foodstuffs", describes the quantitative determination of mono-methylmercury (MMHg) (10-5000 µg/kg dry weight) in mainly marine biota samples. The principle of the method is that the sample is spiked with an appropriate amount of Hg isotope-enriched MMHg and extracted. After derivatisation the sample is analysed using GC-ICPMS. The GC separates the different mercury species before MMHg is atomised and ionised in the high temperature of the ICP. The ions are extracted from the plasma, and in a mass spectrometer the ions are separated by their mass/charge ratio.
