Samples of corn from commercial markets, previously shown to contain aflatoxin, were examined to determine the distribution of toxin within the bulk of the corn. A greenish-gold fluorescence under ultraviolet light (365 nm.) was associated with the presence of aflatoxin. Damaged kernels with the characteristic fluorescence contained as high as 88,500 to 101,000 p.p.b. aflatoxin B1, indicating that the toxin contamination could be concentrated within a few kernels in a corn sample. In two of thirteen contaminated corns examined, aflatoxin B1 was found in high concentrations in the broken corn-foreign material, accounting for most of the toxin in the total sample of corn.
