Ochratoxin A and ochratoxigenic black Aspergillus species in Tunisian grapes cultivated in different geographic areas

Biodiversity and ITS-RFLP Characterisation of Aspergillus Section Nigri Isolates in Grapes from Four Traditional Grape-Producing Areas in Greece

“…Incidence of isolation and distribution of Aspergillus section Nigri group among the fungal genera were in accordance with previous reports from Greece [20], [51] and other Mediterranean countries [52], [53], [54]. A very high incidence was observed in our samples since 23 out of 33 vineyards sampled presented 100% presence for black aspergilli, although some studies have reported lower indices for vineyards from some European and South American countries [19], [55], [56], [57].…”

Fungal diversity, incidence and mycotoxin contamination in grapes from two agro‐climatic Spanish regions with emphasis on Aspergillus species

“…Undoubtedly, Aspergillus section Nigri are the most important mycotoxigenic (ochratoxigenic) fungi present on grapes (5–83% infected berries) (Table ) . The main black aspergilli species occurring on grapes are biseriates, in particular A. niger aggregate.…”

Occurrence of ochratoxin A in grapes, juices and wines and risk assessment related to this mycotoxin exposure

“…The contamination of grapes with Aspergillus may be minimized by cultivating grapes more resistant to pests and utilization of practices of harvesting and transportation that preserve the integrity of the grapes. The presence of OTA-producing fungi has been occurred in different countries with wine tradition in wine production, incuding Argentina (PONSONE et al, 2007;CHIOTTA et al, 2009), France (CLOUVEL et al, 2008, Italy (LUCCHETTA et al, 2010) and Tunisia (LASRAM et al, 2012).…”

“…In the southern region of Italy, for example, the climate is more humid and warm and in these conditions, the concentration of OTA in grapes can reach high levels. LASRAM et al (2012) evaluated the occurrence of toxigenic fungi and OTA in grapes grown in different regions of Tunisia. A. niger was the predominant specie isolated from grapes (75%), followed by A. carbonarius (22%).…”
