Growth Media
Found in grains, soil, and salted food (1, 5). It is not usually associated with decaying vegetation (5).

Potential Toxin Production
Can produce a kidney toxin ochratoxin A which may produce ochratoxicosis in humans (1, 5). This is also known as Balkan nephropathy (1). The toxin is produced at optimum growth conditions at 25 C and high moisture conditions. The ochratoxin may also be produced by other Aspergillus sp. and Penicillium sp (1). Other toxins which can be produced by this fungus include penicillic acid, xanthomegnin, and viomellein (5). These are all reported to be kidney and liver toxins (5).

Spore Size
Conidia dimensions 25-3 microns (5).

Water Activity
0.77 (5).
