In the present study, a preliminary investigation was conducted on the occurrence of mycotoxin-producing fungi in respirable air and surface dust from farms (N = 4) and feed factories (N = 3) located in the state of São Paulo, Brazil. The main genera detected were Aspergillus sp., Fusarium sp., Penicillium sp., and Cladosporium sp. Aspergillus sp. was identified in more than 50% of samples analyzed. The values of colony forming units (CFU) were higher in feed factories than in farms, with a maximum of 7.10 Log CFU/m2. In samples of respirable dust, average values were 3.12 Log CFU/m3 in animal feed factories and 2.95 Log CFU/m3 in farms. The study demonstrated that the levels of mycotoxin-producing fungi found in the work environments studied may be of concern to the health of the workers.
