Thenature of organochlorine pesticides OCP and their physical-chemicalproperties exert immediate action of control on live systems, which hasjustified their use in agricultural practices. Their long life makes them apersistent ecological aggressor and biomagnifier. They reach foods by bioticand abiotic means, and are absorbed and accumulate in adipose tissue. Inlactation processes, they are excreted in milk through the mobilization offats. Diverse studies have identified them as neurotoxic, affectingreproductive processes, altering the immunological response and act asendocrine disruptors. An analysis was made of the content of organochlorinepesticides in twenty-one samples of infant milk formulas marketed in the southof Mexico City in 2010. The determinations were made following the protocols ofthe International Dairy Federation, by means of gas chromatography withelectron capture detector, and the majority presence was found of α-HCH 100%, β-HCH95.2%, γ-HCH 90.5%, aldrin 85.7%,heptachlor 80.9% and heptachlor epoxide 80.9% with mean values of0.24, 0.13, 0.32, 0.62, 0.92 and 0.18 μg-kg of fat, respectively;all below the limits permitted by the CodexAlimentarius. With null or lower recurrence and in lowerquantities, thefamily of DDT, endrin, endrin aldehyde and the endosulphanes were quantified.
