Determination Of A Pyrethroid Insecticide Deltamethrin Residues In Cattle Meat In Baghdad Province/Al-Rusafa

Deltamethrin (DMT) is one of the synthetic pyrethroid compounds having wide insecticidal activity against a large number of ectoparasites and has important uses in veterinary and human health protection.In Iraq DMT has been widely used now in Baghdad and other provinces for sheep, goats and cattle dipping or spraying by the veterinarians and farmers for controlling of ectoparasites in animals and as insecticide in crop production in agricultures.The aims of this study were to determine the levels (ppm) of DMT residues in locally slaughtered cattle's meat consumed in Baghdad province /Al-Rusafa.A total of 50 cattle's meat samples were collected from 10 different regions of Baghdad province Al-Rusafa (Al-Kurrada Int., Al-Arassat, Al-Aadhamiya, New Baghdad, Al-Ghadeer, Al-Baladiyat, Al-Orffaly, Al-Habibiya, Al-Ameen 1 st , and Al-Ameen 2 nd markets) from October 2015 to March 2016.Five cattle's meat samples were purchased from different butchers per region.These samples were analyzed by using High Performance Liquid Chromatography techniques (HPLC).The residues analysis showed that all cattle's meat samples were positive for DMT residues.The data showed that there were significant (P≤ 0.05) differences in the concentrations (ppm) of DMT residues among the 10 regions of Baghdad province/Al-Rusafa.According to the locations the obtained data were compared with the Maximum residual limits (MRLs) permissible by the WHO and FAO and it was found that there was 2253% violation of the MRLs (above 0.026) in cattle's meat.The results of this study revealed that there were significant differences (P≤ 0.05) in the mean levels of DMT residues (ppm) in cattle's meat, between October and other months during the study period.These data were compared with the Maximum residual limits (MRLs) permissible by the WHO and FAO and it was found that there was 796% violation of the MRLs (above 0.026) in cattle's meat.
