Evidence for Mycotoxin Contamination of Maize in Southern Ethiopia: The Need for Further Multidisciplinary Research
In 130 pre-harvest maize samples from Southern Ethiopia, Aflatoxin B1 (AFB1), Fumonisin B1 (FUMB1) and Ochractoxin A (OTA) were detected with mean concentration of 22.72, 1679.3 and 147.32μg/kg respectively. FUM B1, OTA and AFB1 were also detected with mean concentrations of 984.97, 694.54 and 32.56 μg/kg respectively in storage samples. FUMB1 was predominant both in pre-harvest and stored maize samples. The high incidence of kernel infection with the Fusarium spp (result not shown) was well correlated with the dominance of FUM B1 in the samples. Due to the inherent risk to human and animal health through the consumption of contaminated grains, guidelines for content of different mycotoxins in maize product intended for food and animal feed have to be established. In order to develop such guidelines and to combat mycotoxin problems, there is a possibility to initiate a multidisciplinary research program for maize or other important crops.
