No Aspergillus flavus infection was detected in 156 samples of preharvest sound corn from Indiana in 1971 and only 0.08% (all from southern Indiana) from 369 samples in 1972. Samples were routinely treated with 5% NaClO. Incidence of A. flavus infection increased slightly in selected samples surface disinfected with 1% NaClO for 30 sec. and cultured at 35 C., but no aflatoxin was detected in these infected samples. A. flavus averaged 0.6 and 1.6% in physically damaged corn in 1971 and 1972, respectively. A. flavus and aflatoxin detected in 8 of 163 combine-harvested corn samples may have developed after harvest. A bright greenish-yellow fluorescence (BGYF), similar in appearance to the BGYF reported in A. flavus-infected corn, was noted on uninfected kernels and cobs free of aflatoxin.
