Abstract: Introduction. Contamination due to organochlorine pesticides on food is considered as a serious threat for\nhuman health, given their high toxicity, bioaccumulation and persistence. Cow milk is used as an indicator of the\npersistence of these pesticides in the environment, because of the milk Ls importance and, in general, of the role\nof dairy products, especially for children. This has been a reason to study pasteurized milk from Colombia and\ncompare the results with previous research works in other countries. Objective. To determine the remains of\norganochlorine pesticides contained in liquid pasteurized milk sold by stores located near to pasteurization plants\nin Cartagena. Materials and methods. 24 bags of milk, from randomly chosen commercial brands and daily\nprovided, were analyzed. The analytic technique of gas chromatography with detector of micro electrons capture\nwas used to determine the content of organochlorine insecticides. Results. For this research work the remains\nof ¿-chlordane (0,90 mg/kg), À-chlordane (0,12 mg/kg), endosulfan I (0,04 mg/kg), endosulfan II (0,001 mg/kg), endosulfansulphate\n(0,002 mg/kg), p,pf-DDT (not detected) p,pf-DDE (0,01 mg/kg), p,pf-DDD (0,01 mg/kg), endrin\n(0,027 mg/kg), endrinketone (0,042 mg/kg) and endrin aldehyde (0,009 mg/kg) were determined. Conclusion. The\nresearch work concluded that some concentrations of the pesticides analyzed were high when their values were\ncompared to those recommended by FAO/WHO in their maximum residual levels (MRL).
