FENAMIPHOS JMPR 1978
Explanation
Fenamiphos was evaluated by the 1974 and 1977 Joint Meetings
(FAO/WHO, 1975a, 1978a).
At the 10th Session of the Codex Committee on Pesticide
Residues (Alinorm 79/24: para. 163) the delegation of Australia
indicated that they had data which supported a higher MRL for
carrots than that proposed (namely 0.05 mg/kg at limit of
determination). The evaluation of these data is covered by this
monograph addendum.
RESIDUES IN FOOD AND THEIR EVALUATION
RESIDUES RESULTING FROM SUPERVISED TRIALS
Data were obtained on residues arising from the use of
fenamiphos on carrots in Australia where the present authorised
rate of application is 9.6 kg/ha. These data are shown in the
table.

RECOMMENDATIONS
On the basis of the new residue data obtained from Australia,
together with the data evaluated at earlier sessions of the Joint
Meeting the following amended MRL for carrots is recommended. The
limit is for the sum of fenamiphos, its sulphoxide and its
sulphone. This definition of the residue now also applies to
previous recommendations, which were formerly for "the sum of
fenamiphos, its sulphoxide, and its sulphone, expressed as
fenamiphos".
