A total of hundred random samples of raw milk were collected from the markets and from dairy farms in Dakahlia Governorate, fifty samples each. All milk samples were analysed for chemical contaminants to determine some heavy metals (lead, cadmium and copper), also to determine some pesticides and carbamate residues (chlorpyrifosmethyl, profenfos, carbofuran, aldicarb and methomyl). The obtained results showed the means concentration of heavy metals (lead, cadmium and copper) in milk samples collected from the markets were 0.08, 0.06 and 1.35 ppm respectively. While the means concentration of lead, cadium and copper in samples collected from dairy farms were 0.04, 0.02 and 1.07 ppm respectively. Regarding to pesticides and carbamate residues (chlorpyrifosmethyl, profenfos, carbofuran, aldicarb and methomyl) their mean concentrations were 0.0018, 0.0021, 0.0014, not detected and 0.0007 mg/kg weight, respectively in milk samples collected from the markets, while the mean values for the samples collected from dairy farms were 0.0006, 0.0012, not detected, 0.0028 and not detected, respectively. So we advice to follow major principles that underlie strategies for improving the efficiency and effectiveness of food control: The efforts are focused on issues that pose the greatest risk. The government must establish food safety requirements, facilitate industry's compliance with these and then ensure that the requirements are through a range of regulatory measures and frequent examination of marketed milk.
