Ochratoxine A (OTA) is a toxic substance contaminating several foodstuffs. Recently, it has been found in grapevine products. The aim of this work was to monitor toxigenic fungi in several commercial vineyards, representative of vine growing in Southern Italy and of Apulia. The results showed a higher contamination of musts by these fungi compared with the past. They belong mainly to the genera Aspergillus and Penicillium. These fungi are responsible for secondary rots of the grapevine. The Aspergillus population was predominant on Penicillium, whilst A. niger prevailed on A. carbonarius. The presence of OTA in the musts was more widespread and significant than in the past years. The OTA must contamination was assessed by HPLC, showing values which frequently exceeded the provisional maximum admissible limit.
