Blood cockle has been recognized as an alternative protein and mineral source which is potential to be diversified as a new food product. Kerupuk kerang darah (traditional Blood cockle cracker) is one of food products made from blood cockle. Nevertheless, blood cockle is known for its capability of accumulating heavy metal such as lead (Pb) and mercury (Hg) and other heavy metals, depends on its habitat. The purpose of research was to investigate levels of the heavy metal lead and mercury content in Kerupuk kerang darah (traditional blood cockle cracker). This study used a completely randomized design with 5 different blood cockle powder supplemented crackers (K = 0%, P1 = 5%, P2 = 10%,P3= 15%, P4 = 20%). Onion Cracker was used as control (K). Measurement of lead and mercury level was done with AAS method. Data analysis was performed with one-way ANOVA and LSD. Result showed that the average lead level on control group (K) and blood cockle supplemented groups (P1-P4) were 0.1593 ppm; 0.1581 ppm; 0.1672 ppm; 0.1693 ppm; and 0.1740 ppm respectively. The average mercury level on control group (K) and blood cockle supplemented groups (P1-P4) were 0.0037 ppm; 0.0033 ppm; 0.0040 ppm; 0.0057 ppm; and 0.0067 ppm respectively. It was concluded that blood cockle powder supplementation increased the lead level in cracker (p=0.003) but did not increase the mercury level (p=0.091). Both levels of lead and mercury in Gorontalo blood cockle cracker were below the National Standard for heavy metals in food (SNI 2009), made it safe for consumption.
