We conducted a survey of fumonisin B1, B2 and B3 contaminations in feed ingredients and formula feeds (109 samples) distributed in Japan in 2004-2005. Fumonisins were determined with LC/MS after purification with ion-exchange cartridge column. Fumonisins were detected in all samples of corn and its by-product, milo (grain sorghum), rye and formula feed. No contamination was observed in dehulled rice, cotton seed and alfalfa. The mean values of fumonisin B1 concentration in corn and formula feed were 350 and 340 micro g/kg, respectively, the highest value was 1,900 micro g/kg in corn.
