Natural occurrence of mycotoxins and mycoflora of Argentinien popcorn

Argentina is the first popcorn exporting country worldwide. In 1997-1998 harvest season, 40,000 ha were sown with a production of 125,000 tons; 120,000 tons of this production were exported to more than 40 countries. The objectives of this study were to isolate and to identify the fungi present in t...

Broccoli, A.M. De Souza, J.C. Argentina is the first popcorn exporting country worldwide.

The objectives of this study were to isolate and to identify the fungi present in this cereal and to assess the occurrence of mycotoxins in freshly harvested popcorn in Buenos Aires province, Argentina, in 1999. All popcorn samples showed fungal contamination. A total of 4,211 isolates were recovered from popcorn kernel samples. The prevalent species isolated was Fusarium verti-cillioides followed by Pénicillium funiculosum, F. graminea-rum and Alternaría alternata. No aflatoxins, zearalenone, de oxynivalenol or ochratoxin A were detected in the 42 popcorn simples. All samples but one were contaminated with fu-monisins (FB) in a range in μg/kg of (not detected-529) for FB 1 (not detected-216) for FB 2 and (not detected-103) for FB 3 . Fumonisin contamination levels in Argentinean popcorn were lower than observed in flint corn. No significant differences in fungal and fumonisins contamination levels were observed in the different tested hybrids. Fil:González, H.H.L. Universidad de Buenos Aires.
