SOME HEAVY METALS RESIDUES IN FRESH HEN EGGS MARKETED IN ZAGAZIG CITY, EGYPT

Two hundred fresh hen eggs were collected randomly from supermarkets in Zagazig city, Egypt to analyze the contents of lead and cadmium in yolk and albumin. Results revealed that the mean concentrations (range) of lead and cadmium in yolk were 0.350 ppm (0.051 to 0.700) and 0.015 ppm (0.005 to 0.025) respectively. While, the mean concentration (range) of lead in albumin was 0.110 ppm (0.030 to 0.260). Grading of examined whole egg samples according to permissible limits, it was clear that all whole egg samples were within the permissible limit of cadmium, while only one sample (5%) exceeded the permissible limit of lead. The public health hazard of heavy metals was discussed and the preventive measures to produce high quality and safety eggs and also protect the consumers were suggested.
