RESUMO
A total of thirteen genera of bacteria and two genera of yeasts were detected in surface sterilized and unsterilized Brazilian commodities and spices such as cashew kernels, Brazil nut kernels, black and white pepper. The genus Bacillus with eight species was by far the most common. The yeasts isolated were Pichia sp., P. guillermondii and Rhodotorula sp. Bacillus cereus, Salmonella typhimurium and Staphylococcus aureus were detected in cashew and Brazil nut kernels.

A total of thirteen genera of bacteria and two genera of yeasts were detected in surface sterilized and unsterilized Brazilian commodities and spices such as cashew kernels, Brazil nut kernels, black and white pepper. The genus Bacillus with eight species was by far the most common. The yeasts isolated were Pichia sp., P. guillermondii and Rhodotorula sp. Bacillus cereus, Salmonella typhimurium and Staphylococcus aureus were detected in cashew and Brazil nut kernels.
Um total de 13 gêneros de bactérias e 2 de leveduras foi detectado a partir de amêndoas de castanha de cajueiro, de amêndoas de castanha-do-Brasil e de pimenta-do-reino preta e branca produzidas no Brasil. O gênero bacteriano mais freqüentemente encontrado foi o Bacillus, com 8 espécies. As leveduras Pichia sp., P. guillermondii e Rhodotorula sp., isoladas somente a partir de amêndoas de cajueiro, apresentaram populações mais elevadas que as de bactérias. Bacillus cereus, Salmonella typhimurium e Staphylococcus aureus foram também detectadas em amêndoas de cajueiro e de castanha-do-Brasil.
