Bee-pollen is an apicultural product with potential for medical and nutritional applications; therefore, its microbiology quality should be monitored. In this context, the objective of this study was to diagnose the microbiological quality of 45 dehydrated bee-pollen samples collected from November 2011 to December 2013 in nine Brazilian States. All the samples were negative for sulphite-reducing Clostridium spores, Salmonella, coagulase-positive Staphylococcus and Escherichia coli, which are micro-organisms of public health concern. Total aerobic mesophilic micro-organism counts ranged from <10 to 1.10 x 10(4) CFU g(-1), with psychrotroph counts ranging from <10 to 1.12 x 10(3) CFU g(-1) and total coliforms from <10 to 2.80 x 10(3) CFU g(-1), while the values for yeasts and moulds were between <10 to 7.67 x 10(3) CFU g(-1). According to the literature, the microbiota observed in this study were typical; however, it is important to consider that these microorganisms may cause spoilage and diminish shelf life, reason by which quality control programs should be implemented.
