    RESIDUES

    Explanation

    The codex Committee on Pesticide Residues requested the Meeting to
    reconsider the definition of the residue. The original data submitted
    to the 1971 Meeting 1/ were studied for this purpose. The major
    metabolite in plants is the sulphoxide of the parent compound. Its
    sulphone and the sulphoxide and sulphone of the oxygen analogue are
    present at much lower levels. In contrast to plant samples, the
    sulphoxide of the oxygen analogue is the major metabolite (ca. 97
    percent) in milk. No information was available on the proportion of
    different metabolites in meat and many of the plant commodities.
    Consequently, the definition of the residue cannot be charged.
