In the present work, microbiological profile of thirty-seven samples of labeled honey were collected in a Protected Geographical Indication “PGI” area of Tadla-Azilal region, which is an endemic zone of Euphorbia resinifera plant. A profile was assessed using conventional microbial methods, like enumeration, detection and/or germs identification, in accordance with ISO norms. This is the first study in which a honey with Moroccan “PGI” was tested, in order to assess its compliance with bacteriological recommendations. Coliforms (Total and fecal Coliforms), Salmonella spp., Shigella spp., Sporus of Bacillus cereus and Clostridium perfringens were not detected. The numbers of Standard Plate Count “SPC” were less than 102 CFU.g-1 for all samples. The molds and yeasts were found among samples and 32% and 40% of samples were positive, respectively. However, no samples showed a higher value than recommended limit [102 CFU.g-1]. We conclude that samples of labeled euphorbia honey of Tadla-Azilal analyzed present good commercial quality parameters (SPC, molds and yeasts “absence of unwanted fermentations”), a good sanitary quality (absence of coliforms and S. aureus) and are safe (Slam., Shig., Sporus of B. cereus and C. perf.). Standardization (regulation and specifications) and a rationalization of beekeeping techniques throughout Euphorbia “PGI” area studied may further sustainably improve the quality of this unique honey, and ensure it over the years.
