Aspergillus flavus is a species of fungus that is often found in corn that can produce mycotoxins, such as aflatoxin B1 (AFB1). Sekelan is a staple food that has potential as a substitute for rice. Sekelan raw material is corn. Corn has the potential contaminated by AFB1 when handling during harvest and post-harvest is not appropriate and when consumed by humans and animals can cause health problems. Sekelan are consume daily by the community in the Tretep Sub District. The samples consist of corn, sekelan and ready to eat sekelan, obtained from five villages in the Tretep Sub District. Fungal contamination testing, measurement of water activity (aw), AFB1 concentration analysis and risk assessment carried out on samples of corn and sekelan. Fungal contamination in corn dominated by white mycelia fungi followed by the genera Aspergillus, Penicillium, Eurotium and Trichoderma. Fungal contamination on sekelan dominated by white mycelia fungi followed by genera Aspergillus, Penicillium and Eurotium. Aflatoxigenic fungi (A. flavus) contaminate 1 of 16 samples of corn while sekelan not found aflatoxigenic fungi contamination. Aw value in corn samples ranged between 0576-0933, sekelan ranged between 0483- 0883 and ready to eat sekelan ranged between 0.96-0.98. AFB1 concentrations of all samples were below the LOD (LOD = 1.75 ppb). Half LOQ value (2.916 ppb) was used as the concentration of AFB1 in calculating exposure. AFB1 exposure amount is 0.079 μg/kg bw/day or 3.8 μg/person /day. Sekelan consumption by the community of Tretep Sub District range from 117.1-358.7 g/person/day. Sekelan in Tretep Sub District is still within safe limits for consumption.
