Descrição: Twenty samples of rough rice (Oryza sativa) (unpolished kernels) collected during the 1995 harvest season from Arkansas (seven samples) and Texas (13 samples) were obtained from rice fields known to include plants with symptoms of Fusarium sheath rot putatively caused by Fusarium proliferatum. Samples were analyzed for fumonisin B1 (FB1) at three laboratories using three different extracting solvents by high-performance liquid chromatography (HPLC) or enzyme-linked immunosorbent assay (ELISA) methods. Forty percent of the samples were positive for FB1 at levels less than or equal to 4.3 micrograms/g by HPLC. The same samples contained FB1 at less than or equal to 3.6 micrograms/g when measured by an ELISA method. Most samples that were positive for FB1 were positive for fumonisin B2 (FB2) and fumonisin B3 (FB3) by HPLC at levels less than or equal to l.2 micrograms/g. Very good agreement was obtained among the two laboratories using HPLC methods and the third using ELISA. Shelling of the unpolished rice results in hull and brown rice fractions. In a sample that contained 4.3 micrograms/g in whole kernels, the fumonisin level was very high in hulls (less than or equal to 16.8 micrograms/g) and low in brown rice (less than or equal to 0.9 micrograms/g). Milling of brown rice results in bran and white rice fractions. Fumonisins were found in bran at a level of less than or equal to 3.7 micrograms/g but were below the level of detection by HPLC in white rice. The presence of fumonisins (FB1, FB2, and FB3) was confirmed by fast atom bombardment/mass spectrometry. This is the first report of fumonisins in naturally contaminated rice in the United States
