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