Mycoflora and Potential Mycotoxin Production of Freshly Harvested Blueberry in Concordia, Entre Ríos Province, Argentina

Abstract

Blueberries cv. Misty (2009) and cvs. Emerald, Jewel, and Misty (2010) were analyzed for mycoflora occurrence in the main production area of Argentina. Isolation frequencies and relative densities of the fungal species were statistically compared. Alternaria tenuissima was predominant and the potential presence of Alternaria toxins may pose a risk for blueberries consumption. This is the first report of Aspergillus flavus, Alternaria alternata, Alternaria vaccinii, Arthrinium phaeospermum, Cladosporium cladosporioides, Curvularia lunata, Epicoccum nigrum, Eurotium chevalieri, Fusarium graminearum, Fusarium semitectum, Fusarium verticillioides, Geotrichum candidum, Mucor racemosus, Penicillium citrinum, Trichoderma harzianum and Trichocladium spp. isolated from blueberries in Argentina.
