Abstract: This research was developed in two swine housings in the phases of nursery and finishing: in two pens each, in two farms located at Salto County, SP, with the objective to evaluate ammonia and concentrations, and fungi presence besides estimating the occupational risk of exposure to these environmental agents. The evaluations were done according to recommended by the norms NR-15, NIOSH e ACGIH. Results indicated significant difference in ammonia concentration in relation to the hour, the housing and to the day period. They also indicate negligence to sanitary ventilation matter in nursery housing with consequent higher level of ammonia; which are linked to the air circulation inside housing, the manure and curtain management, housing typology, and to local climate conditions; besides swine crowd and density. Total dust concentration was higher in nursery buildings (0.84-9.16mg.m -3) than in finishing (0.84-3.34mg m -3), while inhale dust was higher in the nursery, however lower than 3.67mg m -3, and within the labor welfare limits. There were found fungi from genus Aspergillus, Penicillium and Neurospora in suspension in the internal environmental of the studied housings.
