Aspergillus flavus and aflatoxin contamination of leguminous trees of the Sonoran Desert in Arizona.

Aspergillus species in section Flavi were frequently associated with desert tree legunes in uncultivated areas of the Sonoran Desert in Arizona. Of 270 samples of debris and fruits of mesquite (Prosopis species), ironwood (Oneya tesota), acacial (Acacia species) and palo verde (Cercidium and Parkinsonia species), 87% were positive for A. flavus (S and L strains) and I tamarii. Mesquite pods were both the substrate from which A.flavus was recovered most frequently and the substrate from native habitats with the greatest aflatoxin content. Twenty percent of legume pods collected in the desert contained measurable quntities of aflatoxin, ranging from 1 to more than 2,500mg/kg.
