Fungal contamination and mycotoxin natural occurrence in oats for race horses feeding in Argentina

A mycological survey was carried out for the first time, on oat samples with hull collected in the Argentinean province of Entre Ríos in 2006. Twenty-three oat samples were evaluated. Aflatoxins, zearalenone, deoxynivalenol and fumonisins were also analysed. Species of the genus Alternaria were the...

Twenty-three oat samples were evaluated. Aflatoxins, zearalenone, deoxynivalenol and fumonisins were also analysed. Species of the genus Alternaria were the most prevalent component of the oats mycoflora. Species belonging to Aspergillus, Fusarium, Arthrinium, Acremonium and Curvularia genera were also recorded. The predominant species of these isolated genera were Alternaria alternata (0.59 of specific relative density) and Aspergillus flavus (0.34).

Based on the observed prevalence of Alternaria alternata, the potential presence of toxins such as tenuazonic acid, alternariol and alternariol monomethyl ether may pose a contamination risk for oats produced in Entre Ríos Province.
