Corn and mixed feed samples harvested in 1994 and 1995 from the northern part of Italy (Province of Varese) have been analysed regarding the contamination with fumonisin B(1), B(2), B(3). Analysis was performed by high performance liquid chromatography (HPLC) with fluorescence detection after derivatisation with o-phtaldialdehyde (OPA). All feed samples consisting of only maize were found to be positive in fumonisin contamination (FB(1): between 0.4 ppm and 19 ppm, FB(2): between 0.6 ppm and 8 pp, FB(3): between 0 ppm and 5 ppm). FB(3) could be detected in samples containing high concentrations of FB(1) and FB(2). The fumonisin concentrations in feed samples investigated did not vary considerably from the harvest of 1994 to 1995.
