Abstract This study was undertaken to evaluate workers' exposure to mycoflora in rice mills in an Indian region. The airborne fungal communities were isolated and identified quantitatively. Of all the isolates, genus Aspergillus was predominant and among the Aspergillus species, A. flavus was the common isolate, irrespective of the method applied for sample collection. The number of isolates recovered from exposed workplaces was significantly greater than in control areas. The percentage of aflatoxin positive strains of A. flavus was 8%. Surface morphology of aflatoxin positive strains was studied by scanning electron microscopy. High concentrations of total and respirable dust concentrations were found in the exposed workplaces, whereas in the stores only the total dust concentration was significantly higher than in control areas. The study indicates that rice mill workers are occupationally exposed to airborne aflatoxin producing strains of A. flavus and should be equipped with protective masks.
