RECOMMENDATIONS FOR METHODS OF ANALYSIS AND SAMPLING (Agenda Item 10)


(a) Revision of Recommended Methods of Sampling for the Determination of Pesticide Residues
(b) Revision of the List of Recommended Methods of Analysis for Pesticide Residues and Other Matters Related to Methods of Analysis for Pesticide Residues

(a) Revision of Recommended Methods of Sampling for the Determination of Pesticide Residues[20]

82. The Committee considered the referenced documents with the assistance of the ad hoc Working Group on Methods of Analysis, which had considered the Proposed Draft Recommended Methods extensively during this Session and had made a number of proposals for amendments.

83. The Committee exchanged views on sampling of low fat meat for determination of residues of fat-soluble pesticides; and the portion of stone fruits on which MRLs were established and which should be taken into account when calculating residue levels. After some discussion, the Committee accepted all the proposed amendments contained in CX/PR 97/12, and those recommended by the Group, except the deletion of Sections 2.3 and 5.2 in Table 3 on sampling of meat parts without adhering fats. The Committee also agreed to add notes in Sections 1 and 4 of Table 3 referring to Sections 2 and 5, respectively. The Committee decided to advance the Proposed Draft Recommended Methods of Sampling as amended[21] to Step 5 for adoption by the Commission with the understanding that at its next session the Committee would consider only fundamental issues.

84. To promote coordination within Codex, the Committee agreed to bring the amended document to the attention of the CCMAS and CCRVDF.

(b) Revision of the List of Recommended Methods of Analysis for Pesticide Residues and Other Matters Related to Methods of Analysis for Pesticide Residues[22]

- Revision of the List of [Recommended] Methods of Analysis for Pesticide Residues

85. The Committee was informed by the Chairperson of the ad hoc Working Group, Dr. van Zoonen (The Netherlands) that an updated list had not been prepared. He offered to screen validated methods from the current list and to prepare a less complicated document. The Committee noted that the Working Group had considered the merits of recommending generic methods or criteria with which methods should comply but no conclusion had been reached.

86. Member Governments were again invited to provide methods for cycloxidim (179), etofenprox (184), clethodim (187), teflubenzuron (190), fenarimol (192), fenpyroximate (193) and haloxyfop (193).

- MRLs Set at or about the Limit of Determination (LOD)

87. The Committee agreed to maintain MRLs for abamectin set at or about the LOD at 0.01 mg/kg.

- Others

88. In relation to the lack of validation data for methods of analysis for veterinary drug residues[23] and, to an extent, pesticide residues, the Committee supported the proposal of the CCRVDF that the Commission request FAO and WHO to give consideration to convening an expert consultation on method validation for food control purposes.

89. The Committee agreed to convene a new ad hoc Working Group under the Chairship of Dr. van Zoonen (The Netherlands) at its next session.
