FONSECA, Homero. Sampling plan for the analysis of aflatoxin in peanuts and corn: an update. Braz. J. Microbiol. [online]. 2002, vol.33, n.2, pp.97-105. ISSN 1517-8382.

The aim of this paper was to update the sampling plan for analysis of mycotoxins in grains, formerly published by the author. The proposed alterations were based on the acquired experience on its application and on FAO recommendations. This update restricts the scope of the former plan and establishes a sampling plan for analysis of aflatoxin in peanuts and corn, by means of modified formulas, the minimum number of sacks or points (when in bulk) from which incremental samples should be drawn to make a bulk sample. Fractional exponents (square roots) of the formulas proportionally decrease the number of sacks/points to be sampled as the lot size increases. Operating Characteristic (OC) curves developed for in-shell and shelled peanuts and corn as well as trend curves of the coefficient variation for different sample sizes (weights) are presented.

Palavras-chave : Sampling; peanuts; corn; aflatoxin; analysis.
