Residues in the edible portion of food commodities
All the residues from supervised trials were in edible items.
RESIDUES IN FOOD IN COMMERCE OR AT CONSUMPTION
Information was provided on residues of flumethrin in the perirenal fat of animals from an Australian random survey from July 1993 to December 1995. No residues (<0.02 mg/kg) were found in the fat of 2545 pigs, 801 horses, 642 goats, 158 deer, 154 buffalo 94 game pigs, 93 kangaroos, or 27 game goats. Flumethrin is not registered in Australia for use on these animals, but data were available because multi-residue methods were used. Although flumethrin is not registered for use on sheep in Australia, one of 4675 samples of sheep fat contained a residue in the range >0.1-0.2 mg/kg. Residues were also detected in perirenal beef fat in 59,6657 samples (0.9%), distributed as shown below.

As a follow-up, treatment histories were obtained in 26 cases. Although details of the treatments were not recorded (except that they were pour-on treatments) they were reported to have complied with GAP. Residues were detected up to 1.1 mg/kg (Table 15).

1 The nature of the samples was not specified but they were presumably perirenal fat because the study was to follow up positive results in random monitoring of perirenal fat and because it is Australian regulatory practice to analyse perirenal fat (Webster et al., 1996).2 This sample was from a cow which was not known to have been treated.
