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

Abstract

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.

Toxic effects of Lambda-cyhalothrin, on the rat thyroid: Involvement of oxidative stress and ameliorative effect of ginger extract

“…Lambda-cyhalothrin (LCT) is a manufactured pyrethroid insecticide that is being used in home pest control, agriculture, protection of food production and disease vector control [ 33 , 88 ]. LCT has been widely used to control pests, including aphids, Colorado beetles and lepidopteran larvae, [81] and was detected in milk, the blood of dairy cows [ 17 ] and cattle meat [ 43 ]. It has been reported that exposing rats to LCT leads to hepatotoxicity and severe renal structure injury due to its toxicity in rats [ 83 ].…”

Pesticides residues in retail meat and offal

“…EL-Shemi and Abou EL-Ella (2015) found that mean residual levels of cypermethrin in tissues of male sheep were 64.2 ±3.05, 12.2 ±0.20 and 62.4 ±3.03 for kidney, liver and muscle, respectively. Moreover Khashan(2016) reported that the levels of deltamethrine pesticide residues in cattle meat samples during October and March were (0.66±0.16µg/kg), and (0.28±0.08µg/kg), respectively. And also Abdu-rrahman (2016) mentioned that mean of DMT (deltamethrin) residues in sheep meat collected from different locations of Sulaimaniya province during June and July was (0.50±0.08µg/kg), (0.99±0.18µg/kg), respectively.…”
