Abstract
Thirty raw milk samples including buffalo farm, bulk tank milk and  cow's farm,10 of each were randomly collected. Samples were collected from different dairy milk places in Mansoura city, Dakahlia governorate during summer and winter of 2006&2007. All samples were used for microbiological examination and to determine the residual of some pesticides. Obtained results represented the mean values of microbiological quality of raw milk on either general or specific cultivation media. Results exhibited high values of the microbial count in the tested raw milk samples appeared on tryptone glucose extract agar (TGEA), they were 82.03 ±79.19 x 103 , 119.40±62.58 x 103 and 129.03 ± 113.60 x103 cfu/ml in examined buffalo, bulk tank, and cow's milk samples, respectively. Obtained results indicated that the pesticide residues concentrations in all samples collected during summer season were lower than that samples collected during winter season. Results showed that the mean values of aldicarb residue was the highst values in examined buffalo, bulk tank, and cow's milk samples, they were 0.0344, 0.0391 and 0.0129mg/kg, respectively.  The residues levels of pesticides in different milk types were lower than the acceptable daily intake (ADI), in summer and winter seasons on contrast the residue concentration of aldicarb and carbofuran were higher than the ADI in winter season. Profenfos insecticide was found in all samples either times in summer or winter season.
