Aflatoxin contamination of grain dust was evaluated. Various grain dust samples from Superior, Duluth, and Georgia were analyzed for aflatoxins by thin layer chromatography. Particle size distributions of Georgia corn dust samples also were determined. No aflatoxins were recovered from any of the Superior or Duluth samples. The Georgia corn dust sample contained 130 parts per billion of aflatoxin-B1 (1162658). The heaviest aflatoxin-B1 contamination was associated with the fraction of particles less than 7 micrometers. The authors conclude that grain workers in dust laden areas could be exposed to aflatoxins by inhalation.
