Main outcomes of the IDF/ISO Analytical Week
Back

Over 190 experts gathered at the IDF/ISO Analytical Week (23-27 May) in Lyon, France, to discuss the latest developments and future projects for methods of analysis in the dairy sector, in project groups and standing committee meetings and a mid-week symposium. exploring the theme “How can analysis promote sustainability in the dairy chain?”.


Successfully hosted by the IDF French National Committee (FIL France), the joint IDF/ISO event provided a platform for experts to work on topical analysis issues, such as the need for a reference system for somatic cell counting in milk, and initiatives underpinning food safety testing.


Workshop collaborative studies and standard development

A Two hours workshop was organized to help experts and project leaders in particular, with the organization and process of the collaborative studies, thanks to exercises based on a case study. This workshop was very well received, and the organizers will make available a template for the statistical treatment of data in order to help the projects groups in their evaluation.


Symposium on “How can analysis promote sustainability in the dairy chain?” 25 May 2011

All speakers presented new initiatives and recommendations that showed for the first time that the analysis sector makes significant contributions to the advancement of a sustainable dairy industry, in particular on the economic and environment standpoints. The symposium highlighted the triple bottom-line sustainability.

IDF expert Sophie Bertrand presented current IDF activities focused on LCA methodology, water quality and water footprint, and ecosystem and biodiversity. ISO expert Magali Tralan presented the principles of the innovative standard ISO 26000 on corporate social responsibility.

Hans Cruijsen (NL) demonstrated that within-laboratory initiatives can reduce the burden on the environment through the implementation of the ISO 14001 standard as part of the company policy towards corporate social responsibility.

Félicie Faucon-Lahalle (FR) presented the PhénoFinlait project which aims at developing precise milk composition analysis methods for sustainable milk production. These methods could help understanding how genetics and feeding strategies impact milk composition, and allow estimation of greenhouse gas emissions based on fatty acid profiles.

Furthermore Moniek Muskee (NL) showed that specifically-developed new testing methodology was developed to reducing chemical uses, adapted for maximized recycling in water waste testing.

Finally Richard Johnson (NZ) underpinned wider sustainability initiatives by the dairy sector such as using FTIR technology to improve waste water management practices, while minimizing the financial impact of solids losses.

The takeaway message is that analyses in the dairy chain are becoming cleaner, more efficient, and comprise a set of tools from the farm to the dairy plant to evaluate impact on environment and the maintenance of corporate social responsibility.

After the symposium, participants had the choice between the technical visit at BioMérieux, which allowed participants to discover the range of activities and products produced by Biomérieux for microbiology analysis, and a technical workshop where the sponsors presented their latest developments.


Highlights from Standing Committee meetings


  • SC Analytical Methods for Additives and Contaminants (SCAMAC)

The SC acknowledged the publication of the ISO/TS 15495|IDF/RM 230 – Determination of melamine and cyanuric acid in milk powders and infant formulas, and noted the Codex request to validate a method in order to endorse the method. The PG will reflect on how to validate the method according to the criteria approach.

A first draft of the guidelines on detection limits of screening methods and MRL's confirmatory analysis and penalties for antibiotic residues was available and lead to a additional New Work Item (NWI) proposal on guidelines for the validation of screening methods for residues of veterinary medicines.


  • SC on Analytical Methods for Composition (SCAMC)

The collaborative studies for the merger of part 1 & 2 and extension of scope of the ISO 8968|IDF 20 – Determination of nitrogen are now completed. The working draft will be updated accordingly and enter the ISO process.

The NWI on Determination of fatty acids has been approved with IDF and ISO, and the SC agreed to extend of its scope to encapsulated products, and also to a wider range of products.

Several NWI proposals are under preparation.


  • SC on Analytical Methods for Dairy Microorganisms (SCAMDM)

A proposal for NWI on Enumeration of lactic acid bacteria by flow cytometry will be sent shortly for approval. However for current work items and new proposals, active project leaders are needed.


  • SC on Analytical Methods for Processing Aids and Indicators (SCAMPAI)

The SC advanced all work items including the revision of the standard on determination of alkaline phosphatase activity, Determination of lipase activity, determination of chymosin and bovine pepsine contents, and determination of total-milk clotting activity. The SC is also considering several new work items proposals.


  • SC on Harmonization of Microbiological Methods (SCHMM)

The SC has prepared IDF input to work items to be discussed at the ISO/TC34/SC9 level.


  • SC on Statistics and Automation (SCSA)

The SC is finalizing the revision on the IDF 135B – Precision characteristics of analytical Methods - as an IDF Bulletin for guidance for the use of ISO 5725 for milk and milk products.

The SC also noted the important progress of several Project Groups regarding the IDF/ICAR project on Reference System for Somatic Cell Counting, the revision of ISO 9622|IDF 141 – Guidance on operation of Mid-Infra Red Instruments, and on the revision of the ISO 16297|IDF 161 : Guidance on Evaluation of Routine Methods for the Determination of Bacteriological Quality.


Minutes of the meetings of the Standing Committees will be available by mid-July on the IDF Intranet (password needed).
