Forty-seven corn samples were collected in 1989 from Linxian and Shangqiu Counties in Henan Province, the high- and low-risk areas, respectively, for human esophageal cancer in the People's Republic of China. The samples were analyzed for fumonisin (fumonisin B1 [FB1] and FB2) contamination. Of the fumonisin-positive samples, the mean levels in Linxian corn were found to be 872 ng/g for FB1 and 448 ng/g for FB2, while the Shangqiu corns had 890 ng of FB1 and 330 ng of FB2 per g. The incidence of fumonisin contamination of Linxian corn (48%) was about two times higher than that of Shangqiu corn (25%), and the former corn samples were frequently cocontaminated with trichothecenes. Fusarium species isolated from corn from Linxian County produced FB1 at levels ranging from 1,280 to 11,300 micrograms/g.
1989年,分别从河南省林县和商丘县采集了47份玉米样本,这两个县分别是中华人民共和国食管癌的高风险和低风险地区。对样本进行了伏马毒素(伏马毒素B1 [FB1]和FB2)污染分析。在伏马毒素呈阳性的样本中,发现林县玉米中FB1的平均含量为872纳克/克,FB2为448纳克/克,而商丘玉米中FB1为890纳克/克,FB2为330纳克/克。林县玉米伏马毒素污染发生率(48%)约为商丘玉米(25%)的两倍,且前者玉米样本常被单端孢霉烯族毒素共同污染。从林县玉米中分离出的镰刀菌属产生的FB1含量范围为1280至11300微克/克。
