In this work we determined the microbiological quality of honey at different processing points and the environmental quality within honey houses, in order to enlarge and complete a research we started in 2009. Mould and yeast (MY), aerobic mesophilic heterotrophic bacteria (CHMB), spore forming bacteria and spores of clostridia number as well as the presence of Shigella spp., Salmonella spp. and fecal coliforms were determined in 163 samples of honey from eight honey houses of the Pampas Region (Argentina). Results showed that 89 samples had ≤10 cfu of MY g-1 while 69 ranged from 10 to 50 cfu g-1, except two that reached 65.5 cfu g-1. Eighty one percentage of the samples showed ≤30 cfu of CHMB g-1 while only seven samples had between 50 and 54.25 cfu g-1. Thirty six samples of honey were obtained from drums: in 25 samples (69.4%) counts of CHMB were less than ≤30 cfu g-1 of honey; in 20 samples (55.5%) values of MY were between 10 and 50 cfu g-1 of honey and total coliforms were only detected in 20 samples from 2014. Fecal coliforms, spores of clostridia as well as Salmonella spp. and Shigella spp were not detected in honey from drums and less than 50 spores of Bacillus spp. g-1 of honey were observed. We can conclude that the microbiological honey quality at honey houses did not show sanitary risks. The information given to the honey house owners would help them to understand the need of applying proper honey handling and sanitation practices.
