Prevalence of pesticide residues in fish, cheese and human milk [electronic resource].

Includes references.

Pesticides constitute the major source of potential environmental hazard to man and animal as they are present and concentrated in the food chain. This investigation was conducted on 78 samples of fish, hard cheese (Ras cheese) and breast milk collected randomly from four governorates of Egypt over a period of 12 months and analyzed to establish their contamination levels with organochlorine pesticides. The results obtained indicated that the mean value of (endrin+dieldrine);Ʃ HCH and ƩDDT were 0.23, 0.177, 0.13, 1.59, 1.62 and 0.73 in fish samples collected from Assiut and El monifiah, respectivaly. P'P'-DDT revealed the highest level and frequency in hard cheese with mean values 1.91, 1.7 and 1.31 ppb for the samples collected from Assiut, Cairo and Domitta governorates respectively. The level of lindane and Aldrin + dieldrin were higher than the MRL in all cheese samples collected. On the other side 6 Breast milk of 10 samples were positive for DDTs (17- 176 ppb) and five samples containing ƩHCH with mean value of 33.6 ppb.
