Residues in food in commerce or at consumption

National monitoring data were supplied by Australia, The Netherlands, Poland, and the UK.

The results of monitoring analyses of samples taken randomly from export and domestic sources undertaken by Australia from 1 July 1993 to 31 December 1995 are shown in Table 43 (Anon, 1996b).

¹ Determined residue was described as being in the range "Reporting limit - <0.2 x Reporting limit"
Samples described as fat are portions of adhering fat taken from animal carcases

The results of monitoring in The Netherlands in 1991-1994 are shown in Tables 44 and 45 (Olthof, 1996).

Residues <LOD are assumed to be at half the LOD for the calculation of the mean.

In 1994, 120 samples of glasshouse and 20 samples of field-grown cucumbers were analysed for chlorfenvinphos residues in Poland (Anon 1996a). No measurable residues were found although the LOD was not reported.

Monitoring in the UK gave the results shown in Table 46 (Anon, 1989-92).
