Performance of three pnematic probe samples and four analytical methods used to estimate aflatoxins in bulk cottonseed.

In Arizona, USA, cottonseed samples for aflatoxin analysis are collected from 100 ton piles by an accumulation of three or more probing with a pheumatic probe. When sampling compacted cottonseed piles, the large official pneumatic probe (7.6 U 127 cm) decrease in efficiency. Two smaller probes (1.9 U 127 cm and 1.9  U 254 cm) were therefore developed and tested for their suitability for sampling cottonseed piles. Three rapid analytical methods (one TLC and two immunochemical) were tested for suitability as on-site assay systems. An analysis of variance of the analytical test results showed no differences between the various probes tested. Of the rapid methods, only the AflaTest-P immunoaffinity column gave results similar to those of the official AOAC TLC method.
