SUMMARY AND CONCLUSIONS

The Twentieth Session of the Codex Committee on Methods of Analysis and Sampling reached the following conclusions:

MATTERS FOR CONSIDERATION BY THE COMMISSION AND THE EXECUTIVE COMMITTEE:

- Recommended the adoption of the IUPAC/ISO/AOAC Harmonized guidelines for internal quality control in analytical chemistry laboratories (paras. 37-40);

- Recommended amendments to the Committee’s Terms of Reference (paras. 63 & 67);

OTHER MATTERS OF INTEREST TO THE COMMISSION
- Agreed in principle to accept the criteria approach for evaluating methods of analysis for Codex purposes (para. 17);

- Agreed that the following quality criteria be adopted by laboratories involved in the official import and export control of foods:

  • Comply with the general criteria for testing laboratories laid down in ISO/IEC Guide 25:1990
  • Participate in appropriate proficiency testing schemes for food analysis which conform to the requirements laid down in “The International Harmonized Protocol for the Proficiency testing of (Chemical) Analytical Laboratories”,
  • Whenever available, use methods of analysis which have been validated according to the principles laid down by the Codex Alimentarius Commission; and
  • Use internal quality control procedures, such as those described in the “Harmonized Guidelines for Internal Quality Control in Analytical Chemistry Laboratories” (para. 21);

- Recommended the adoption of the IUPAC/ISO/AOAC Harmonized Protocol for the use of Recovery Factors for Codex purposes when the protocol was published by IUPAC (para. 27);

- Agreed to request Commodity Committees to identify how extensive the problem of indirect determinations was in Codex Standards (para. 30);

- Agreed to define selected core terms of direct relevance to the work of Codex and circulate to governments and international organizations for comments (para. 34);

- Noted the report of the Inter-Agency Meeting (para. 47);

- Noted the progress report on review of standard methods of analysis and sampling (para. 48);

- Requested commodity Committees to avoid selecting methods of analysis which use ozone-depleting solvents (paras. 61 & 62) and

- Proposed to undertake the following new work:

  • Review of methods of analysis using ozone-depleting substances and
  • Measurement uncertainty (para. 66).
