Abstract
The exposure of farm workers to aflatoxin (1402682) was investigated. The amount of airborne aflatoxin generation by the operation of combines was examined. Sampling indicated that use of an air conditioning system in the cabs of the combines was an effective control measure. During unloading, using an cab without an air conditioning system, the levels of airborne dust reached as high as 231.1mg/m3. Aflatoxin levels varied greatly but levels as high as 195 parts per billion (ppb) were recorded. Much of the higher concentrations of aflatoxins may be in Aspergillus-flavus spores, which can remain airborne for some period of time. Grain elevators located near towns may be a source of hazardous emissions for the population. During harvesting the grain handlers, truckers and farmers may be exposed to highly varying amounts of aflatoxin, particularly in the southern parts of the United States. Attempts were made to develop a mathematical relationship between the level of aflatoxin in airborne dust and the concentration of aflatoxin in bulk corn. The aflatoxin entering the air appeared to be related to the method of handling and the history of the corn being processed. Significant levels of aflatoxins were found in and around large commercial grain elevators.
