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.

Explanation
This pesticide was evaluated in 1966 (FAO/WHO, 1967b)* and new
information and/or specific aspects of its use have been considered at
each subsequent meeting, and the appropriate monograph addenda issued
(FAO/WHO 1968b and 1969b).*
The Fourth Session of the Codex Committee on Pesticide Residues asked
for clarification concerning the kinds of "fruit and vegetables"
covered by the tolerance recommendations (FAO/WHO, 1968b and 1969b);*
also for information on the periods after application of the pesticide
and/or harvesting at which the tolerances were to apply. Certain
member countries had expressed the view that the tolerances could be
lower if a few days were to pass before the tolerance were to be
applied, as would usually be the case in commerce. The Joint Meeting
was therefore asked to reconsider this aspect.
EVALUATION OF RESIDUES IN FRUIT AND VEGETABLES
The data on which the previous recommendations had been based were
reviewed at the Meeting. These data included some evidence to suggest
that it might be possible to set tolerances lower than 8 ppm for
certain kinds of fruit. An no new data had been received, since the
Fourth Session of the Codex Committee and as the Meeting was aware
that further work on the subject had been carried out since the
previous review was undertaken, it was decided to postpone the full
consideration of the matter until 1970, by which time the additional
data could be made available.
FURTHER WORK OR INFORMATION
REQUIRED (for 1970 Meeting)
1. Information on the residues in fruit and vegetables following uses
in accordance with good agricultural practice in different
countries.
2. Information on the minimum periods likely to pass between
application and/or harvesting and the time the tolerance is to be
applied in different countries.
