New edition: NMKL Procedure 4 Validation and Verification of Chemical Analytical Methods
NMKL Procedure 4 describes how to validate and verify chemical analytical methods and was revised in 2026, and transferred to the new NMKL template.
The revisions include various changes and improvements: text generally clarified for readability, updated references, clarification on acceptance of reproducibility and definition of selectivity, and clarification of calculation formulas.
NMKL Procedure 4 Ed. 4 (2026) was issued 8th of July 2026.
New version: NordVal Protocol 1 Validation for Microbiology
NordVal International Protocol No. 1 Validation of microbiological alternative (proprietary) methods against a reference method version June 2026 is available here: Validation protocols – NMKL
The protocol follows the EN ISO 16140-2: Microbiology of the food chain — Method validation — Part 2: Protocol for the validation of alternative (proprietary) methods against a reference method.
New in the version of June 2026 (29.06.26):
- The protocol has been aligned with ISO 16140-2 Amd 1, except for the recognised errors in the amendment, and LOD has been included as described.
- For qualitative studies, new formulas have been included for both MCS and ILS.
- For the ILS, calculations are included for paired studies only (not unpaired studies).
- For quantitative studies, the Excel file includes Bland–Altman plot and Accuracy Profiles for both MCS and ILS, organized in separate worksheets. For the Bland–Altman analysis, there is a minor modification to the confidence factor, using 1.96 instead of 2, i.e. no big change for the plots.
- For the Accuracy Profile, the ISO spreadsheets are recommended.
New edition: NMKL107 Titratable acidity. Determination in Milk and Cream.
NMKL 107 Ed. 3 2026 Titratable acidity. Determination in Milk and Cream specifies a routine method for determination of the titratable acidity in all types of milk and cream. The revision includes layout update and the option to use pH-meter instead of colorimetric indicator.

NordVal 050 Compact Dry YM RAPID from Shimadzu Diagnostics Corporation was renewed with additional 2 years validity until 15.06.28.
The method has been tested for enumeration of viable yeasts and moulds in a broad range of foods.
Renewed: NordVal 020, 022, 049 for Bio-Rad RAPID methods
The NordVal certificates for the Bio-Rad RAPID broad range methods were renewed with additional 2y validity:
- NordVal 020 RAPID’E.coli 2 Agar – NMKL valid to 14.05.28
- NordVal 049 RAPID’Staph – NMKL valid to 20.05.28
- NordVal 022 RAPID’L.mono – NMKL valid to 14.05.28
New edition of Proc 12 Guide on Sampling for Analysis of Foods
NMKL published 30 Apr 2026 a new edition of the Procedure 12 Guide on Sampling for Analysis of Foods.
This guide is intended for anyone involved in planning and conducting sampling for analysis of foods.

Correction to NMKL 71 Ed. 6 2025 Salmonella. Detection in Foods.
The 4th of April 2026 the method “NMKL 71 Ed. 6 2025 Salmonella. Detection in Foods” published 20 March 2025 were corrected:
- In “11.3 Selective enrichment” a sentence was added: “As an alternative, the incubation time can be extended to 48 ± 4 hours.”
- In “11.6 Confirmation” a sentence was rephrased “Presumptive colonies should be confirmed.” and a sentence added “Alternatively, whole-genome-sequencing (WGS) can be applied for serotype determination.”
NMKL methods in Codex (CCMAS45)
NMKL was represented at the 45th session of the Codex Committee on Methods of Analysis and Sampling (CCMAS45) in Budapest, Hungary, 9 – 13 March 2026.
Several NMKL methods were endorsed as Codex standards, and the official report from the meeting is available from the CCMAS45 website and the link here.
The Codex Alimentarius is a collection of internationally adopted food standards and related texts presented in a uniform manner. These food standards and related texts aim at protecting consumers’ health and ensuring fair practices in the food trade. The publication of the Codex Alimentarius is intended to guide and promote the elaboration and establishment of definitions and requirements for foods to assist in their harmonization and in doing so to facilitate international trade.
New edition: NMKL 201 Sensory quality control of marine oils Ed.2
A new edition of NMKL 201 Sensory quality control of marine oils Ed.2 2026 was published 27 Mar 2026.
The method describes a sensory quality test of marine oils as an umbrella term for oils extracted from fish, shellfish or marine mammals that are rich in healthy polyunsaturated fatty acids.
