Abstract
Detection of pesticides residues in milk of ruminants represents a human public health hazardous. In this study, milk was monitored using Gas chromatography (GC), for one organochlorine pesticide residue dielderin and high performance liquid chromatography( HPLC) for deltamethrin as pyrothroid pesticide residues to determine the degree of environmental pollution with both of them .The study included examination of 60 milk samples (30 fresh dairy milk which were collected from some farms at Assiut Governorate and 30 ultra- heated milk (UHT), which collected from different shops and supermarkets at Assiut Governorate.
The results of the study revealed that 30% of raw milk samples were polluted with dieldrin pesticide residue and 20% were polluted with deltamethrin pesticide residue while (13.33%) of UHT milk samples were polluted with dieldrin pesticide residue and 6.66% were polluted with deltamethrin pesticide residue. The mean concentration of dieldrin and deltamethrin pesticide residues in raw milk were 210.1 ± 126.7ppb and 100.0 ± 83.8 ppb respectively, while in the ultra-heated milk samples, the mean concentration of dieldrin and deltamethrin pesticide residues were 98.0.25±63.0 ppb and 18.0 ±8.55 ppb respectively.
On comparison of the data recommended by the Food and Agricultural organization/ World Health Organization (FAO/WHO 2008), it was found that none of obtained values exceeded the recommended values. The results of this work indicated that in spite of the banning much of organochlorine and pyrothroid pesticides still contaminating the environment resulting in contamination of food stuffs, particularly milk. There is a potential risk of the consumption of such contaminated milk on human’s health particularly infants and children.
