DIETARY EXPOSURE ASSESSMENT FOR AFLATOXIN B FROM PROCESSED PEANUT PRODUCTS IN MUNICIPALITY OF BOGOR 1

A research on dietary exposure assessment for aflatoxin B (AFB1) from processed peanut products in Municipality of Bogor was carried out. The objectives of this study were to determine the contents of AFB1 in processed peanut products at retail levels, and to obtain information whether there is a risk to public health caused by the consumption of processed peanut products contaminated by AFB1. Survey of processed peanut product consumption was carried out by interviewing each respondent using a questionnaire of weekly processed peanut product consumption. Sampling of processed peanut products was conducted at the locations where the respondents obtained processed peanut products. The number of roasted peanuts with skin pods, flour-coated peanuts and or sauces samples was 33, respectively, while the number of and sauces samples was 18 and 12, respectively. The total number of processed peanut product sampleswas 129. AFB1contentwas determined usingThin LayerChromatographymethod. Estimation of the dietary exposure assessmentwas determined using the actual survey data consisting of AFB1 content, consumption data and body weight. The highest contaminated sample percentage and mean of AFB1 content was found in roasted peanuts with skin pods i.e. 42 % of 33 samples and 43.2 μg/kg, respectively, followed by flour-coated peanuts (30 % of 33 samples and 34.3 μg/kg), and or (21 % of 33 samples and 17.1 μg/kg). Mean of estimated dietary exposure for AFB1 found in children was 15.2 ng kg bw day and 95 percentile exposure was 38.9 ng kg bw day, while in adults 9.0 ng kg bw day and 95 percentile exposure was 27.0 ng kg bw day. The excess cancer risk of AFB1 exposure in Bogor from this study on children and adults was calculated as 193 and 115 cancers/year, respectively dietary exposure assessment, aflatoxinB, processed peanut product
