在2004年至2007年期间，我们检查了日本零售商店的食品中赭曲霉毒素A（OTA）和伏马菌素B-1、B-2和B-3的污染情况。共检测了27种不同产品的1，358个样本的OTA，检测了16种不同产品的931个样本的伏马菌素。OTA的定量限为0.01至0.5 μ g/kg，伏马菌素的定量限为2至10 μ g/kg。在小麦粉、意大利面中检测到的OTA含量高于定量限。燕麦片、黑麦、荞麦粉和荞麦干面条、葡萄干、葡萄酒、啤酒、咖啡豆和咖啡制品、巧克力、可可和香菜。在90%以上的速溶咖啡和可可样品中发现了OTA，并且OTA的浓度最高。12.5在葡萄干中检测到了2.5mg/kg的苯甲酸。燕麦片、黑麦、葡萄干、葡萄酒和烘焙咖啡豆中OTA的浓度每年都有显著变化。在冷冻和罐装玉米、爆米花中检出伏马菌素。玉米粉玉米片，玉米汤，玉米点心，啤酒菜豆，小米，芦笋。伏马菌素B-1、B-2和B-3的最高浓度在玉米粉中检出（分别为1，670、597和281 μ g/kg）。所有的玉米粉样品都被伏马菌素污染。爆米花和玉米零食的样品中超过80%含有伏马菌素。在日本的几种食品中检测到OTA和伏马菌素，尽管日本没有对这些真菌毒素设定监管水平，但它们的浓度相对较低。
Between 2004 and 2007 we examined foods from Japanese retail shops for contamination with ochratoxin A (OTA) and fumonisins B-1, B-2, and B-3. A total of 1,358 samples of 27 different products were examined for OTA, and 931 samples of 16 different products were examined for fumonisins. The limits of quantification ranged from 0.01 to 0.5 mu g/kg for OTA and 2 to 10 mu g/kg for the fumonisins. OTA was detected in amounts higher than limits of quantification in wheat flour, pasta. oatmeal, rye, buckwheat flour and dried buckwheat noodles, raisins, wine, beer, coffee beans and coffee products, chocolate, cocoa, and coriander. OTA was found in more than 90% of the samples of instant coffee and cocoa, and the highest concentration of OTA. 12.5 mu g/kg, was detected in raisins. The concentration of OTA in oatmeal, rye, raisins, wine, and roasted coffee beans varied remarkably from year to year. Fumonisins were detected in frozen and canned corn, popcorn grain. corn grits. cornflakes, corn Soups, corn snacks, beer. Soybeans, millet, and asparagus. The highest concentrations of fumonisins B-1, B-2, and B-3 were detected in corn grits (1,670, 597, and 281 mu g/kg, respectively). All of the samples of corn grits were contaminated with fumonisins. and more than 80% of the samples of popcorn grain and corn snacks contained fumonisins. OTA and fumonisins were detected in several food products in Japan however, although Japan has not set regulatory levels for these mycotoxins, their concentrations were relatively tow.
