Fungi and mycotoxin contamination of agricultural commodities is a major problem in Indonesia as well as in other tropical countries. This is due to the high temperature and humidity, which favor the growth of fungi, followed by producing their toxin. Among mycotoxin, aflatoxin is the most concern problem to be discussed in this paper. Aflatoxin is the highest priority mycotoxin problem in Indonesian agricultural commodities, particularly corn and peanut.
Current data showed that approximately 51 % of corn samples obtained from East Java region were found to contain AFB1 at levels of 20 ppb or higher, and 18% of them had contamination level of higher than 100 ppb. In the case of peanut, data showed that peanut from farmers at Central Java region generally contained low level of AFB1 (< 20 ppb), however, 50% peanut samples obtained from traders contaminated by more than 20 ppb of AFB1. Peanut and corn based products were found to have AFB1 residues which some of them more than 20 ppb.
Based on the current data on aflatoxin level at agricultural products, Department of Food and Agricultural Product Technology, Gadjah Mada University has developed several strategies in prevention and control of this mycotoxin, particularly in corn and peanut, in collaboration with other universities, research institutes, government, farmer, traders, and industries. Several performance indicators are targeted such as increasing the productivity, quality, safety (low aflatoxin level) as well as market share of these commodities, increasing awareness of aflatoxin problem and income of farmers.
