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.
