Abstract
Methods to assess the exposures of farmers to the mycotoxin aflatoxin-B1 (1162658), in airborne grain dust were investigated. Aflatoxin-B1 was extracted from dust samples using chloroform or methylene-chloride, followed by several concentration and purification steps. Four local farms in the Midwest were selected for inclusion in the collection of airborne samples during the harvest. Personal air sampling pumps were used to collect dust samples on fiberglass filters at two locations, inside and outside the cab of the harvesting combine. Bulk corn samples were also collected for comparison of their aflatoxin-B1 levels with the airborne concentrations. The highest concentrations of aflatoxin-B1 found in dust collected during harvest and grain unloading were 67 and 92 nanograms/cubic meter (ng/m3), respectively. Higher levels of aflatoxin-B1 were found in the airborne dust samples collected from enclosed animal feeding buildings (421ng/m3) and during grain bin clean out (4,849ng/m3). Aflatoxin-B1 concentrations of up to 5,100 parts per billion (ppb) were measured in settled dust taken from enclosed animal feeding buildings. The authors conclude that farmers and farm workers may be exposed to potentially hazardous concentrations of aflatoxin-B1, particularly during grain bin clean out and feeding animals in enclosed buildings.
