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 The certification was withdrawn 31.12.2022.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- The method or procedure is outdated or superfluous – withdrawal, the pdf file is available for 5 years in the Repealed folder then removed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.

NMKL 162, 1998. Total dietary fibre. Gas chromatographic, colorimetric and gravimetric determination in foods – Uppsala method
The methods from our cooperation partner AOAC can replace the withdrawn NMKL methods:
NMKL 129 can be replaced by AOAC 985.29 or AOAC 991.43.
NMKL 162 can be replaced by AOAC 994.13.

Method 137 on bacterial count in raw meat is withdrawn
The Method 137 “Bacterial count. Determination by direct epifluorescent filter technique (DEFT) in raw minced meat.” was withdrawn 02 Nov 2022 and moved to the Repealed folder. This means that the method will not be further maintained, but available on nmkl.org for 5 years.
New edition: NMKL Procedure 17 Guidelines for Requirement Specifications for Food Analysis
NMKL Procedure 17 “Guidelines for Requirement Specifications for Food Analysis” 2nd Edition was published 25 October 2022. The procedure was elaborated by a project group within NMKL. The rational for revision was an update due to new EU regulations, especially on requirements and designation of laboratories for analysis in official controls and other official activities in addition to new EU regulation on procurement.
