AFB1 in corn and corn dust was determined in 24 samples of airborne dust collected from 8 farms during harvest, 22 samples from 9 farms during animal feeding and 14 sets of Andersen samples from 11 farms during bin clearing. A total of 14 samples of settled dust and 18 samples of bulk corn were also collected and analysed. The airborne concentration of AFB1 bound in dust collected during harvest and grain unloading ranged from 0.04 to 92 ng/m3. Higher levels of AFB1 were found in the airborne dust samples collected from enclosed animal fedding buidings (5 –421 ng/m3) and during bin cleaning (124 – 4849 ng/m3). AFB1 up to 5100mg/kg were detected in settled dust collected from an enclosed animal feeding building,; however, no apparent correlation was found between the airborne concentration of AFB1 and its concentration in settled dust or bulk corn.
