The degree of aflatoxin contamination in groundnut hulls used as cattle feed was determined by analyzing inoculated hand-shelled hulls and hulls from groundnuts known to contain aflatoxin. Hulls adjusted to 20% moisture, inoculated with Aspergillus flavus and incubated for 7 days at 25°C supported growth of the fungus but not aflatoxin production. Groundnuts from 20 selected lots with visible A. flavus contamination contained 13-353 p.p.b. aflatoxin. The machine-shelled hulls from these lots were analyzed and 3 lots contained no detectable aflatoxin, 13 lots contained 4-88 p.p.b. and 4 lots contained > 116 p.p.b. Aflatoxin concn of 53-87 p.p.b. were detected in hulls when groundnuts containing relatively high levels of aflatoxin (up to 26.8 p.p.m. in damaged kernels) were carefully machine-shelled. Hulls from the same samples obtained by hand-shelling contained no detectable aflatoxin. Separating hulls over a 4.76 mm screen appeared to provide a means of removal of most aflatoxin-containing particles in groundnut hulls
