Aspergillus are fungal species like a A flavus and A parasiticus and they are able to develop secondary metabolites called mycotoxins. They grow quickly under ideal conditions. From the moment one discovered its danger for health resulted from the presence of aflatoxins in foods, an achievement was carried out to evaluate the presence of a mycotoxins lifiting in benefited polished rice type 1, used by Brazilian army. The samples were collected at " 5º Batalhão de Suprimento" (army departament) from November 2003 to febuary 2004 when the incidence of aflatoxins B1, B2, G1 and G2 was measured by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC) methods. This work had the aim of comparing the thin layer chromatography and high performance liquid chromatography techniques and contributed for the quality control of the foods to be consumed by militaries of the Brazilian army, concerning the control of the aflatoxins levels. From a total of 30 samples were tested performed by tlc, no aflatoxin was detected. From 26 samples, analysed trough high performance liquid chromatography, 6 (23, 07%) presented positive results for aflatoxin B1 with 0, 54 2, 04 µg/kg and, 1 (3, 84%) presented a positive result for aflatoxins B2 with 1, 84 µg/kg.
