Organochlorine pesticides are widely used in both public health campaigns and agricultural practices since the'70s. The confirmation of organochlorine residues in human and animal fat tissues as well as its great stability in the environment and its mobilization throughout the planet made its use restricted and even banned. However, organochlorine residues are still detected in different strata; and currently, highly toxic products are still commercialized. The main objective of this work was the qualitative and quantitative determination of organochlorine pesticides in raw milk that is produced for human consumption in the Dr. M. Belgrano Department in San Salvador de Jujuy (Jujuy-Argentina). Raw milk samples from local dairy farms were analyzed. Gas chromatography was used to identify and quantify pesticide residues. Among the detected residues were: endosulfan (30% samples), lindane (5%), exogen heptachlor epoxide, endrine, trans-chlordane, hexachlorocyclohexane (55%), and dichlorodiphenyltrichloroethane (DDT) residues. Some of these residue levels were higher than the maximum allowed by the current (trans-clordane) local legislation while others were below the limits. It was also detected residues of pesticides used in agricultural practices of neighboring tobacco plantations. The bromatological quality of the samples from all the dairy farms met the Código Alimentario Argentino requirements. Even tough direct producer-consumer commercialization is illegal in Argentina; this ban is not strictly enforced. All the samples analyzed contained residues of at least one organochlorine pesticide, and although they were in small concentrations they represent a health hazard since this type of food is for the elderly, children and the sick.
