A total of 315 marketable and 57 obviously damaged corn samples were collected at 116 different farms and country elevators located in the United States in countries selected from among those producing more than 1 million bushels of corn in 1972. The samples were analyzed for aflatoxins and zearalenone. The most striking correlations observed were between geographical area and mycotoxin contamination. Aflatoxin contamination was most frequently encountered in the Southeast-Appalachia areas with a 44% incidence of marketable corn with detectable aflatoxins. Zearalenone was most frequently encountered in the Corn Belt with 10% incidence in marketable corn from that region. When mycotoxin contamination was found in an establishment, most of the samples from that establishment were contaminated. There was no correlation between mycotoxin contamination and storage practices nor could the observed contamination of marketable corn be related to the contamination of the obviously damaged grain. These observations plus correlations with the geographic incidence and aflatoxin level distribution of published field contamination data suggest the possibility of a common contamination mode.
1972年，在美国116个不同的农场和乡村粮库收集了共计315份可销售的玉米样本以及57份明显受损的玉米样本，这些农场和粮库位于玉米产量超过100万蒲式耳的国家中挑选出的美国境内。对这些样本进行了黄曲霉毒素和玉米赤霉烯酮分析。观察到的最显著的相关性存在于地理区域和霉菌毒素污染之间。黄曲霉毒素污染在东南部-阿巴拉契亚地区最为常见，可检测到黄曲霉毒素的可销售玉米的发生率为44%。玉米赤霉烯酮在玉米带最为常见，该地区可销售玉米中的发生率为10%。当在某个机构中发现霉菌毒素污染时，该机构的大多数样本都受到了污染。霉菌毒素污染与储存方式之间没有相关性，可销售玉米中观察到的污染也与明显受损谷物的污染无关。这些观察结果加上与已发表的田间污染数据的地理发生率和黄曲霉毒素水平分布的相关性，表明存在共同污染模式的可能性。
