Listeria Velox certified by NordVal International
The certificate NordVal 058 Listeria Velox was just issued to DNA Diagnostic 10 Feb 2023 and is valid for 2 years.
Listeria Velox is a fast, simple, and reliable method for horizontal detection of Listeria monocytogenes and Listeria species in food and environmental samples. Using an 18 hours-enrichment step, a simple and easy extraction protocol followed by a fast, sensitive, and highly specific qPCR reaction, the entire protocol from sample to result can be carried out in 20 hours.
Aerobic microorganisms: Renewed NordVal certificate 018 for Hygicult® TCP from Aidian
NordVal 018 Hygicult® TPC for rapid monitoring of microbiological hygiene from Aidian is renewed until 01.02.2025.
Hygicult® TPC is a hinged dip-slide culture method for the detection of total microbial count from surfaces. The slide is covered on both sides with Total Plate Count Agar which supports rapid growth of most common bacteria and fungi. Hygicult® TPC slides are intended for rapid monitoring of microbiological hygiene in different types of materials – contact plates and swabs.
Discontinued NordVal certificate: 041 Salmonella detection method by real-time PCR
The NordVal 041 certificate for Salmonella detection method by real-time PCR has been discontinued. The certification was withdrawn 31.12.2022.
New edition: NMKL 117. Pathogenic Y. enterocolitica. Detection in food, animal feed and environmental samples.
The NMKL Method No. 117 “Pathogenic Yersinia enterocolitica. Detection in food, animal feed and environmental samples” 4th edition has been published. The principle of the 4th edition has been completely revised compared to the 3rd edition of the method (cold enrichment). Amended cold enrichment protocol has been included as ANNEX 3.
The method can be purchased for 60 Euro or downloaded free of charge for subscribers.
Clarification about Reassessment of Publications
In certain intervals NMKL evaluates the methods and procedures in a process referred to as reassessment (here).
We address whether there are known challenges with the current edition and evaluate if a revision is needed. If we decide that the current edition is still valid a revision is not performed. The current edition is thereby confirmed, meaning that the pdf file available for download is not changed.
The outcome of a reassessment of methods and procedures will be either one of the four options:
- The edition is still valid (confirmed) – the pdf file is kept as is
- Minor adjustments are needed but not qualifying for a new edition – the adjustments are inserted into the pdf file and also noted on the respective webpage
- Revision needed – a new edition is produced and published when ready
- The method or procedure is outdated or superfluous – withdrawal, the pdf file is available for 5 years in the Repealed folder then removed
The information about reassessments is included on the respective webpage for each method and procedure.
