Laboratory shelling and pilot handling operations were conducted to determine if peanut dust generated by such operations contained significant amounts of aflatoxin. Air samples were collected from points of highest dust concentration. No aflatoxin B1 was detected in dust from uncontaminated lots. Aflatoxin B1 levels of 700 ppb and 7.6 ng/m3 were detected from highly contaminated lots. The contamination of the dust was directly proportional to the contamination of the lots handled or shelled. In the shelling tests, the level of contamination of the dust samples was about one-ninth of the level of contamination of the peanuts. In the handling tests, the level of contamination of the dust samples was about half the contamination level of the peanuts. These results indicate that most of the contaminated dust was probably removed by handling operations prior to shelling. Although workers are not routinely exposed to such levels of contaminated dust, these findings suggest the need for a more thorough study of peanut dust during handling or processing of contaminated peanuts.
进行了实验室脱壳和试点处理操作，以确定此类操作产生的花生粉尘中是否含有大量黄曲霉毒素。从粉尘浓度最高的点采集空气样本。未受污染批次的粉尘中未检测到黄曲霉毒素B1。在高度污染的批次中检测到黄曲霉毒素B1水平为700 ppb和7.6 ng/m3。粉尘的污染程度与所处理或脱壳批次的污染程度成正比。在脱壳试验中，粉尘样本的污染水平约为花生污染水平的九分之一。在处理试验中，粉尘样本的污染水平约为花生污染水平的一半。这些结果表明，大部分受污染的粉尘可能在脱壳前的处理操作中被去除。尽管工人通常不会接触到如此高水平的受污染粉尘，但这些发现表明需要在处理或加工受污染花生期间对花生粉尘进行更全面的研究。
