During 1996-1998, 158 smples of poul try feeds were collected from a factory located in Rio Cuarto Cordoba province, Argentina, and assayed for Fusarium species and fumonisin production by these isolates. Among the 43 isolates of F. moniliforme, F. nygamai and F. proliferatum assayed, there was a high degree of variability in the quantities of FB1, FB2 and FB3 produced. The range of concentrations of FB1, FB2 and FB3 produced in corn grain varied from 5.4 to 3,991, 1.01 to 189 and 0.4 to 765 g/kg of corn, respectively. Two strains of F.moniliforme produced exceptionally high concentrations of FB3 and minor concentrations of FB2 and FB1.
