Performance of sampling plans to determine aflatoxin in farmers’ stock peanut lots by measuring aflatoxin in high-risk-grade components.

Five 2 kg test samples were taken from each of 120 farmers’ stock peanut lots contaminated with aflatoxin.  Kernels from each 2 kg sample were divided into the following USDA grade components: sound mature kernels plus sound splits, other kernels, loose shelled kernels and damaged kernels.  The kernel mass, aflatoxin mass and aflatoxin concentration were measured for each of the 2400 component samples.  The variance associated with measuring aflatoxin in each of the 4 combinations of components increased with aflatoxin, and functional relationships were developed from regression analysis.  The variability associated with estimating the lot concentration from each of the 4 combinations of components was also determined.
