METHOMYL       JMPR 1978

    Explanation

         Residue and analytical aspects of methomyl ware evaluated by
    the Joint Meeting in 1975, 1976 and 1977 (FAO/WHO, 1976b, 1977b,
    1978b). No evaluation for acceptable daily intake (ADI) was
    possible owing to lack of data.

         Among the items of further information considered desirable
    were the development of residue analytical method suitable for
    regulatory purposes, and additional data on national use patterns
    and residues from countries other than Australia, the Netherlands
    and the USA. The limited information received on these topics is
    briefly discussed below.

    RESIDUES IN FOOD AND THEIR EVALUATION

    APPRAISAL

         Additional information was provided by several countries on
    use patterns, residues and national MRLs. It in considered that the
    guideline levels already recommended are not likely to be exceeded
    when good agricultural practice as approved in these countries is
    followed. Information about residues in flax, rapeseed and broad
    bean forage was reviewed.

         A high-pressure liquid-chromatographic procedure for residue
    analysis was reported but its utility for regulatory purposes,
    especially at levels below 2 mg/kg, still has to be established.

    FURTHER WORK OR INFORMATION

    Desirable

    1.   Modifications or refinements of available methods of analysis to
         make them suitable for regulatory purposes.

    2.   Further data on the disappearance of residues during storage.
