Abstract
Species of theAspergillus ochraceus group were most abundant in the air of a coffee curing works of the seventeen environments studied at Mysore. They also occurred in large numbers in coffee dust, husk samples, sorghum and paddy. Incubating at room temperature (20–25°C) was found most suitable for enumeration of these species. Only 6.6% of the air-borne isolates of the group produced ochratoxin-A. A. ochraceus was the most common species of the group isolated from air and also yielded a greater proportion of toxic isolates.
