The distribution of aflatoxin concentration in pistachios has been measured by sampling 19 process streams ranging from 1 to 1000 multisample. The fraction of total aflatoxin accounted for by each prpcess stream was computed. It was concluded that 90% of aflatoxin is contained in 4.6% of (low quality) product. Removal of this product would reduce average aflatoxin from 1.2 to 0.12mg/kg for all product sold for human consumption. It is estimated that the necessary sample size (in terms of the sample mean and desired variance of the mean) for aflatoxin measurement in pistachios is given by number of nuts = (8x105mg/kg) x mean/variance.
