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) fromprocessed 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 fromthis study on children and adults was calculated as
193 and 115 cancers/year, respectively
