Resumo: | The production of organic milk has been gaining attention due to global market demand for ecological products. However, data about this product are still very limited in Brazil. The aim of this study was to investigate the chemical residue contamination of organic and conventional pasteurized milk sold in three brazilian states. Five certified brands of pasteurized organic milk and five conventional milk brands were analyzed. The samples were subjected to the determination of 88 compounds (79 pesticides and 9 veterinary drugs). For the extraction of the analytes we applied the modified QuEChERS method and for the identification and quantification of the residue we used Liquid Chromatography Coupled to Mass Spectrometry in Series (LC-MS/MS). Results showed that both organic and conventional milk presented only pesticides contamination. Of the 56 samples, five (8.9%) contained pesticides residues. Three of them being samples of organic milk; two of which, were positive for clomazone and one for chlorpyrifos. In the conventional milk positive samples, one showed monocrotophos the other presented chlorpyrifos. Although there was a low frequency of positive samples and three of the pesticides detected were below the limit of quantification, there is concern regarding these results since the use of monocrotophos has been prohibited in Brazil, and chlorpyrifos showed concentrations above the maximum limit residue, indicating irregularities. Our results reaffirm the importance of monitoring pesticide programs and chemical contaminants in milk, since milk is one of the most consumed animal food in the country. Moreover, our findings showed that the organic milk production is not in compliance with current legislation. |

A produção de leite orgânico vem ganhando destaque como resposta à demanda global do mercado por produtos ecológicos. São escassos os dados sobre este produto no Brasil. O objetivo do estudo foi verificar a contaminação por resíduos químicos de leites pasteurizados orgânicos e convencionais comercializados em três Estados brasileiros. Foram analisadas cinco marcas de leite pasteurizado orgânico certificadas e cinco marcas de leite pasteurizado convencional. As amostras foram submetidas à determinação de 88 compostos (79 agrotóxicos e 9 medicamentos veterinários). Para a extração dos analitos aplicou-se o método QuEChERS modificado. Para identificação e quantificação dos resíduos utilizou-se Cromatografia Líquida Acoplada à Espectrometria de Massas em Série (LC-MS/ MS). Os resultados mostraram que tanto o leite orgânico quanto o convencional apresentaram apenas contaminação por agrotóxicos. Das 56 amostras obtidas, cinco (8,9%) continham resíduos de agrotóxicos, sendo que destas, três eram amostras de leite orgânico (duas foram positivas para clomazone e uma para clorpirifós). Nas duas amostras positivas do leite convencional, em uma detectou-se monocrotofós e em outra clorpirifós. Embora tenha havido baixa frequência de amostras positivas e três dos agrotóxicos detectados estavam abaixo dos limites de quantificação, os dados encontrados preocupam, pois o monocrotofós teve seu uso proibido no Brasil e o clorpirifós apresentou concentrações acima do limite estabelecido pela legislação vigente, indicando irregularidades. Esses resultados reafirmam a importância dos programas de monitoramento de agrotóxicos e contaminantes químicos no leite, visto que o leite é um dos alimentos de origem animal mais consumidos no país. Também demonstram que a produção orgânica de leite não está em conformidade com a legislação vigente.UEL2013-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1349110.5433/1679-0359.2013v34n4p1731Semina: Ciências Agrárias; Vol. 34 No. 4 (2013); 1731-1740Semina: Ciências Agrárias; v. 34 n. 4 (2013); 1731-17401679-03591676-546Xreponame:Semina.
