Risk characterization of consumption of peanuts and peanut sauce (gado-gado, pecel and ketoprak)*

For Hepatitis B population 0.3 x 3.2 = 0.96 cancers per year per 100,000 population per ng aflatoxin per kg bw per day.

For non-Hepatitis B population:0.01 x 3.2 = 0.032 cancers per year per 100,000 population per ng aflatoxin per kg bw per day.

* Sparringa (2008) based on food consumption data 2007; average body weight 60kg; 50 g peanuts in each portion of pecel/gado-gado/ketoprak and aflatoxin concentration as reported by Ambarwati (2007).
