The mycotoxins, $Aflatoxin\;B_1(B)$ and Ochratoxin A(A), were measured from the various mejus manufactured under the artificial or natural conditions by the indirect competitive ELISA; The various fungi isolated from the Korean traditional home (KTH) made meju collected were observed to produce each mycotoxin mentioned above in the toxin producing broth, but only few in the sterilized cereals of soybean under the artificial conditions. Thus, the isolated fungi were not found to produce both A and B toxins in the artificial conditions. Particularly, the any mycotoxin was not determined at the range of 0.01 to 100 ng per gm of the mejus made under the conditions of KTH widely collected in Korea. The mycotoxins produced by the meju-fermenting fungi were seemed or speculated to be degraded in KTH's mejus under the natural conditions. The species of Mucor involved in the initial stage of fermentation were discussed to be important in the fermentations of KTH mejus.
