Abstract
A total of 75 random egg samples were collected from different areas in Sharkia Governoate (25 each of baladi, farm and organic) during the period from june 2016 to September 2017. Samples were packed in polyethelene bags, labelled by the kind, number, site and date of collection then send to the Central Laboratory, Faculty of Veterinary Medicine, Zagazig University, to be examined for heavy metal residues.
1. Lead (Pb) residues in baladi, organic farm and non organic farm egg samples:
Lead (Pb) residues were detected in 25 (100%); 20(80%) and 25(100%) of the examined baladi, organic farm and non organic farm egg samples, respectively, with mean values of 1.64±0.22; 1.23±0.18 and 0.67±0.07 in examined baladi, organic farm and non organic farm egg samples, respectively. Egg yolk samples were more contaminated by lead residues than albumin samples, the mean values of Pb residues were 0.79±0.03; 0.57±0.09 and 0.52±0.05 ppm in the albumin of baladi, organic farm and non organic farm egg samples, respectively. While, Pb residues were with mean values of 2.5±0.43, 1.90±0.27 and 0.83±0.09 ppm in the yolk of baladi, organic farm non organic farm egg samples, respectively. The daily intake from consumption of 100 gm eggs per day (mg/day/person) was 0.164(32.8%); 0.123(24.6%) and 0.067 (13.4%) from baladi, organic farm and non organic farm egg, respectively.
