A limited survey was conducted over a 2-year period to determine the incidence and levels of deoxynivalenol (DON) in corn and wheat grown in selected areas of the United States. Samples of corn (198) and wheat (247) were collected and analyzed by a gas chromatographic method. Sixty-six percent of the corn samples collected in 1984 and 30% of the corn samples collected in 1985 contained DON. The average concentration of DON in corn, by state, ranged from 0.11 to 1.20 micrograms/g; the maximum concentration was 2.47 micrograms/g. Only 2 of the 247 samples of wheat contained DON at a concentration greater than 2 micrograms/g, which is the level of concern suggested by the Food and Drug Administration for wheat entering the milling process for human consumption.
在两年时间内进行了一项有限的调查，以确定美国特定地区种植的玉米和小麦中脱氧雪腐镰刀菌烯醇（DON）的发生率和含量水平。收集了198份玉米样本和247份小麦样本，并采用气相色谱法进行分析。1984年收集的玉米样本中有66%以及1985年收集的玉米样本中有30%含有DON。按州统计，玉米中DON的平均浓度范围为0.11至1.20微克/克；最大浓度为2.47微克/克。247份小麦样本中只有2份所含DON的浓度大于2微克/克，这是美国食品药品监督管理局针对进入供人类消费的制粉流程的小麦所建议的关注水平。
