Fumonisins were monitored in corn grain collected from Bt hybrids grown in 107 locations across the United States in 2000-2002. Bt corn hybrids contain the Cry1Ab protein from Bacillus thuringiensis that controls European corn borers and other stalk-boring pests. Fumonisin levels were frequently lower in grain from Bt hybrids grown in field trials under conditions of natural (FACT trials) or manual insect infestation (university trials). Over three years of FACT trials, there were 126/210 comparisons when fumonisin levels in grain from control hybrids were >2 ppm, exceeding U.S. FDA guidance levels of 2 ppm for human food. Grain from Bt hybrids was at or below 2 ppm of fumonisins for 58 of the 126 comparisons. The use of Bt hybrids can increase the percentage of corn grain that would be suitable for use in food and feed.
2000年至2002年期间，对从美国107个地点种植的Bt杂交玉米中收集的玉米粒中的伏马菌素进行了监测。Bt玉米杂交种含有来自苏云金芽孢杆菌的Cry1Ab蛋白，可控制欧洲玉米螟和其他蛀茎害虫。在自然条件下（FACT试验）或人工虫害条件下（大学试验）进行的田间试验中，Bt杂交种种植的谷物中伏马菌素水平通常较低。在为期三年的FACT试验中，当对照杂交种谷物中的伏马菌素水平>2 ppm，超过美国食品药品监督管理局（FDA）规定的人类食品2 ppm指导水平时，有126/210次比较。在126次比较中的58次中，Bt杂交种的谷物中伏马菌素含量处于或低于2 ppm。使用Bt杂交种可以提高适合用于食品和饲料的玉米粒百分比。
