    PESTICIDE RESIDUES IN FOOD - 1983


    Sponsored jointly by FAO and WHO






    EVALUATIONS 1983





    Data and recommendations of the joint meeting
    of the FAO Panel of Experts on Pesticide Residues
    in Food and the Environment and the
    WHO Expert Group on Pesticide Residues
    Geneva, 5 - 14 December 1983

    ETHIOFENCARB

    RESIDUES

    Explanation

           At the request of the Codex Committee on Pesticide Residues the
    Meeting reviewed the limited data on ethiocarb in the 1977
    monographs1 in beans both with and without pod.  The relevant data
    are presented again in the following monograph.

    RESIDUES IN FOOD AND THEIR EVALUATION

    RESIDUES RESULTING FROM SUPERVISED TRIALS

           Data submitted previously to FAO by Bayer (1974-1979) were
    reviewed and the results are given in Table 1.

    APPRAISAL

           The Meeting agreed that for beans with pod the earlier data,
    together with the data in the 1981 evaluations, could be interpreted
    as supporting a maximum residue level of 2 mg/kg but could find no
    basis to change its earlier estimate of 0.2 mg/kg for beans without
    pod.
