Resumen:
During the 1993 harvest period there was a high
incidence of Fusarium head blight in wheat in
Argentina. Fusarium species that produce trichothecenes
in wheat have been reported in several countries
including Argentina. Several studies have shown that F.
graminearum and deoxynivalenol (DON) were the
main contaminants detected in wheat and by-products
in Argentina. The objective of this study was to evaluate
the occurrence o/Fusarium spp. and DON contamination
in wheat from Cordoba, Argentina during the
1993/94 harvest season. F. graminearum was the main
Fusarium species isolated. From 40 samples analysed,
80% showed DON contamination. The levels of DON
found ranged between 300 and 4500 \ig\kg. There was
good correlation between F. graminearum and DON
contamination. Only five samples showed levels of
DON higher than those established in the guidelines
in Canada and the USA for food and feedstuff s.
