    RESIDUES

    Explanation

    The Codex Committee on Pesticide Residues (CCPR) requested the meeting
    to reconsider the definition of the residue. The original data
    submitted to the 1968 Meeting 1/ and some additional data were
    studied.

    The layer chromatographic tests referred to in FAO/WHO 1968b indicate
    that the concentration of the oxygen analogue in samples of animal
    origin is negligible. The experience of members of the Codex Ad Hoc
    Working Group on Methods of Analysis confirms the lack of oxygen
    analogue in samples moving in commerce, as reported by the 12th
    Session of CCPR, 1980. The exclusion of the oxygen analogue from the
    definition of residues is justified.

    RECOMMENDATION

    The Meeting suggested changing the definition of the residue. The
    maximum residue limits refer to the parent compound alone. The new
    definition does not alter the limits recommended previously.
