The tanning process has preservation of the hide of the animal. The industrialization of animal skins corresponds in its great majority to the skin of bovines. Indoor the tanneries the presence of 11 contamination indicator species in the tanning work environment with pathogenic potential are the following: Bacterium pumilus; Bacterium subtilis; Bacterium cereus; Cladosporium lubricantis, Cladosporium cladosporioides; Penicillium commune; Penicillium echinulatum; Penicillium chrysogenum; Penicillium crustosum; Candida parapsilosis, and Candida albidus. The microorganisms could compromise the state of health of tanning workers due to their incidence, propagation and concentration. This work showed that samples of nasal and oropharyngeal mucosa taken from the tanners (the sentinel group) demonstrated a high burden of bacteria and yeasts, with values up to 76 × 107 CFU/ml for bacteria and 80 × 107 CFU/ml for yeasts, observing bacterial and fungal growth in all of the participants. The nasal-mucosa results of the second group of tanners and of the control group, in which the sample was taken at the clinical laboratory, confirmed the presence of bacteria and fungi previously observed in the first tanners group; however, the concentration was less with respect to the sentinel group of tanners, with values of 1.5 × 103 CFU/ml and 1.9 × 103 CFU/ml for bacteria and yeasts, respectively. In that prior work, the identification was carried out of bacteria, fungi, and yeasts. The bacterial families identified were Bacillaceae, Corynebacteriaceae, Enterobacteriaceae, Moraxellaceae, Nocardiopsaceae, Pseudomonadaceae, and Staphylococcaceae. The genera of fungi identified were mainly Aspergillus and Penicillium, which are considered the most significant allergenic fungi in air, and these have been associated with adverse effects on human and animal health. The yeasts identified were Candida krusei and Candida glabrata, which have been associated with adverse effects on the health of immunosuppressed individuals
