在花生收获后的首次堆放时,由于温度和湿度相宜,在那些外荚裂开或被虫咬穿的花生仁里很容易招致黄曲霉菌的生长,导致花生中黄曲霉毒素含量的增加。由于黄曲霉毒素是非脂溶性的,在用花生仁榨油时,这种严重致癌的毒素就全部留在料饼内。提取脂肪后的料饼一般都是作为饲料喂着牲畜,污染严重的料饼会引起牲畜死亡。即使因程度不十分严重,牲畜没有死亡,这种黄曲霉毒素也会通过牲畜的肉和奶威胁人类的健康。

During the first pile-up after peanut harvest, due to temperature and humidity, the growth of Aspergillus flavus is easily induced in peanuts with outer pods or biting through, resulting in an increase in aflatoxin content in the peanut. Because aflatoxins are non-fat-soluble, these severely carcinogenic toxins remain in the cake when they are pressed with peanut oil. The fat cake is usually fed as feed, and the heavily contaminated cake can cause death of livestock. This aflatoxin can threaten human health through the meat and milk of livestock, even if livestock are not killed to a very low degree.
