The kernels, cobs, husks, leaves and stalks of 50 corn plants from a field heavily infested with Aspergillus flavus were analyzed for aflatoxin. The toxin was not detected in any of the analyzed parts of 7 plants. Aflatoxin was detected in the kernels of 42 plants at levels of 2-18,300 .mu.g/kg. The cobs of 24 plants, all of which had contaminated kernels, contained aflatoxin (range: 1-260 .mu.g/kg). The toxin was detected at lower levels in husks (range: 1-91 .mu.g/kg) of 29 plants, leaves (range: 2-70 .mu.g/kg) of 19 plants, and stalks (range: 1-146 .mu.g/kg) of 20 plants; all of these plants but one contained aflatoxin in the kernels. One plant had aflatoxin (5 .mu.g/kg) only in the husks.
