ABSTRACT:

The aim of this study was to evaluate the presence of microorganisms in honey produced by the stingless bee (SB) jandaíra (Melipona subnitida) from the semiarid region of Brazil. Thirty-five samples were analyzed and all of them were positive for mesophilic bacteria, coliforms at 45°C, fungi, and yeast. Staphylococcus spp. were identified in 85.7%, while Bacillus spp. were detected in 34.3% of honey samples. DNAs of Clostridium perfringens and C. botulinum were detected in 40% and 2.8% of the samples, respectively. Salmonella spp. and C. difficile were not detected. The present research revealed a great diversity of microorganisms in honey produced by jandaíra.

Key words:
Clostridium botulinum; Clostridium perfringens; stingless bee
