This work was accomplished with the aim of evaluating the microbiological characteristic in cassava flours (Manihot esculenta Crantz) simple and temperate, stored during 180 days. The materials consisted of five samples, being one of cassava flour without mixture (simple) and the others of temperate cassava flours. The simple flour was packed in polyethylen bags of low density with capacity of 1,0kg and the temperate flours were packed in colored polipropilen bags, with capacity of 0.5kg. In all the samples fecal coliformes, Staphylococcus aureus, mesophile bacterias, yeasts counting and Salmonella sp research were accomplished. The analyses were accomplished in intervals of 30 days. Differences were not detected among the microbiological characteristic of the simple samples and the temperate ones. The storage didn’t affect the microbiological standard of the samples. The samples presented sterility for fecal coliformes, Salmonella sp. and Staphylococcus aureus. The values found for fecal coliformes, Salmonella sp., Staphylococcus aureus, mesophile bacterias and yeasts were inside the patterns fastened by the Brazilian legislation.
