A total of 52 corn samples collected in 2000 from four main corn production provinces of Iran (Fars,Kermanshah, Khuzestan, and Mazandaran) were analyzed for contamination with
Fusarium verticillioides and fumonisins (FB
1, FB
2, FB
3, and 3-
epi-FB
3). The mean incidence of
F. verticillioides(percent of kernels infected) for these four areas was 26.7, 21.4, 24.9, and 59.0%, respectively. Theincidence in Mazandaran was significantly (
p < 0.05) above that of the other areas. All samples fromMazandaran were contaminated with fumonisins with a mean level of total fumonisins of 10674

g/kg was 53 (8/15), 42 (5/12),and 57% (8/14) in the samples from Fars, Kermanshah, and Khuzestan, respectively, and thecorresponding mean total fumonisin levels were 215, 71, and 174

g/kg, respectively. No statisticaldifferences (
p > 0.05) were observed in the fumonisin levels of the corn samples from these threeprovinces, which were significantly (
p < 0.05) lower than the fumonisin contamination in samplesfrom Mazandaran.
