Considering the qualitative and quantitative losses in post-harvest of grain, in this research was evaluated fungi and mycotoxins contamination in whole rice (Oryza sativa L.) during the stationary drying and storage system. Samples were collected in a period of sixty days in two heights of the warehouse during storage. The initial sample presented 5.4x10(4)CFU g-1; the contamination increased significantly during drying and storage, up to 10(5)CFU g-1. Fungi contamination was different inside the warehouse with higher contamination in the upper portion. The more abundant fungi genera were Aspergillus and Penicillium, A. flavus (26.3%) and P. commune (19.1%) which presented higher incidence. Aflatoxin B1 was produced by four A. flavus isolates, but mycotoxins were not detected in the samples.
