of exposure. This study aimed to messure the level of contamination of heavy metal especially Lead (Pb) and Cadmium (Cd) and the efforts to reduce contamination Pb and Cd in Anas moscha and Ciarina moschata Tissue. The concentration of Pb and Cd in Anas moscha and Ciarina moschata tissues were lower than the maximum acceptable level for Pb and Cd respectively. (1 mg/ Kg for Pb; 0.5 mg/Kg for Cd, SNI 2009). The result indicated that after soaking and boiling in citric acid solution form pineapple extract at concentration 100 % for 60 min at 100 0C reducing heavy metals Pb in Anas moscha from 0.03 mg.Kg-1 to 0.003 mg.Kg-1 and Cd in Anas moschataand and Cairina moschata from 0.027 mg.Kg-1 to 0.003 mg.Kg-1 and 0.022 mg.Kg-1 to 0.001 mg.Kg-1. The highest reduction of Pb and Cd level up to 80 % when samples were boiled in pineapple extract for 1 hour at 1000C. The study concludes that boiled samples in pineapple extract has a potential to reduce the contamination of Pb and Cd.
