The microbiological quality of honey obtained from different processing points and the environmental quality within honey houses were assessed in the Pampas Region (Argentina). Mould and yeast (MY), culturable heterotrophic mesophilic bacteria (CHMB), the number of spore-forming bacteria as well as the presence of Shigella spp., Salmonella spp. and fecal coliforms were evaluated in 163 samples. These samples were taken from eight honey houses. Results showed that 89 samples had ≤10 CFU of MY.g-1 honey, 69 ranged from 10 to 50 CFU.g-1 and two reached 65.5 CFU/g-1. Eighty one percent of the samples showed ≤30 CFU of CHMB.g-1 honey and only seven samples had between 50 and 54.25 CFU.g-1. Thirty six honey samples were obtained from drums: in 25 samples (69.4%) CHMB counts were less than ≤30 CFU.g-1 of honey; in 20 samples (55.5%) the values of MY were between 10 and 50 CFU.g-1 honey and total coliforms were only detected in 20 samples. Fecal coliforms, spores of clostridia as well as Salmonella spp. and Shigella spp were not detected and less than 50 spores of Bacillus spp. per g-1 were observed in the honey from drums. Therefore, the microbiological honey quality within the honey houses did not show any sanitary risks. Our results were reported to honey house owners to help them understand the need to reinforce proper honey handling and sanitation practices.
