One of the most serious problems facing the quality of rice is the presence of mycotoxin-producing fungi, especially the species belonging to the genera Aspergillus, Penicillium and Fusarium. The objective of this study was to check the levels of aflatoxins and identify the fungal population associated with grains of rice received and sold in Belo Horizonte and some cities in the southern state. We analyzed a total of 60 samples of rice: organic, parboiled, full, polished, and the incidence of aflatoxins found in a sample. The results showed that the aflatoxigenic species identified were A. parasiticus and G2 and A. flavus. Using high performance liquid chromatography to assess the incidence of aflatoxin in rice, only one showed a contamination of 1.2 ìg kg-1. Despite the presence of aflatoxigenic fungi, the samples showed no worrying levels of aflatoxin that could endanger the safety of the product and consumer health.
