Due to the great consumers’ demand for organic eggs as a safe alternative, this study was conducted to probe the chemical safety of Egyptian organic eggs and other regularly produced types, in term of toxic metals containment. Cadmium (Cd), Lead (Pb) and Aluminum (Al) were determined by atomic absorption spectroscopy in 150 eggs samples of organic, cagefree home and caged-commercially produced types. Obtained results seemed alarming for all types of tested eggs. 34% and 40% of organic eggs samples exceeded the maximum permissible limit of Cd and Pb, respectively. As a risk assessment model, Target Hazard Quotients (THQ) of examined eggs types presumed low health risk potential. However, Egyptian organic eggs did not seem to be more safer as had been promoted. This study urges reviewing of the regulatory legislations regarding organic food chemical safety.
