    1969 EVALUATIONS OF SOME PESTICIDE RESIDUES IN FOOD

    THE MONOGRAPHS

    Issued jointly by FAO and WHO

    The content of this document is the result of the deliberations of the
    Joint Meeting of the FAO Working Party of Experts and the WHO Expert
    Group on Pesticide Residues, which met in Rome, 8 - 15 December 1969.

    DICHLORVOS

    Explanation

    The monograph on this pesticide was issued after the meeting in 1966
    (FAO/WHO 1967b)* and an addendum, based upon further data, was issued
    after the 1967 meeting (FAO/WHO 1968b).*

    The Fourth Session of the Codex Committee on Pesticide Residues when
    considering the recommendations put forward by the 1967 Joint Meeting
    (FAO/WHO (1968b),* questioned certain points. These were discussed at
    the 1969 Joint Meeting, as indicated in the following monograph
    addendum:

    RECOMMENDATIONS CONCERNING RESIDUES IN FOOD

    Canned and frozen vegetables

    The need to specify tolerances for products other than raw
    agricultural products was discussed in a general way. It was agreed
    that it would be necessary in some cases to specify tolerances for
    partly processed products; flour was an example. So far as dichlorvos
    was concerned, however, the position would seem to be covered
    adequately if it were to be accepted that residues in processed
    products, resulting from postharvest applications or otherwise, should
    not be higher than the tolerances for the corresponding raw
    commodities. Any departure from this position would need to be
    specifically considered with appropriate residue data.

    It was therefore decided that the expression "canned and frozen"
    that appeared before "vegetables" in the previous recommendation
    should be deleted.

    Tolerance on meat

    The information before the 1967 Joint Meeting did not suggest that
    there was a need for a tolerance. As no further data were available
    for review, the meeting was not able to act on the suggestion made at
    the Fourth Session of the Codex: Committee that a tolerance should be
    recommended for dichlorvos in meat.

    Tolerances on cereal products

    In reply to the question from the Codex Committee on Pesticide
    Residues, it was agreed that the tolerance should apply to the milled
    products of cereals to be consumed by man - i.e. flour, cornmeal,
    oatmeal, etc.
