Pyrethroids residues were detected in 45 samples of raw milk, soft cheese and cream (15 of each) collected randomly from different localities at Gharbia Governorate and investigated using High Performance Liquid Chromatography with diodearrary detector (DAD). Flumethrin residues were found in 20, 26.66 and 40% of the examined raw milk, soft cheese and cream samples with an average concentration of 11.53 ± 3.21, 80.82 ± 23.18 and 107.98 ± 27.57 ppb, respectively. All positive raw milk samples were within the Maximum Residual permissible Limit value (MRL) but those of soft cheese and cream showed levels above the MRL. While, cyhalothrin was detected in 26.66, 33.33 and 33.33% of examined samples and all of them showed levels exceeding the MRL with an average concentration of 258.25 ± 170.31, 364.00 ± 182.00 and 379.60 ± 180.78 ppb, respectively. The public health importance of pyrethroids insecticides and possible sources of contamination as well as some recommendations to control such serious residues in milk and milk products were discussed. |
