Exposure assessment to ochratoxin A from the consumption of Italian and Hungarian wines
Abstract A total of 267 wine samples including 19 dessert, 186 red, 11 rose and 51 white produced mostly in the years 1997–2002 in Italian and Hungarian regions were analyzed for ochratoxin A (OTA) using inmunoaffinity column (IAC) clean-up and HPLC with fluorimetric detection. None of Hungarian wine samples were contaminated with this mycotoxin. For Italian red wines, 84% of the samples were positive for OTA ranged from 0.01 to 4.00 ng/mL. Furthermore, OTA was detected in 63% of dessert, in 56% of rose and in 19% of white wine samples ranged from 0.01 to 1.64, from 0.01 to 1.04 and from 0.01 to 0.21 ng/mL, respectively. A study of OTA daily exposure assessment in Italian wines was also car…
Mycotoxin mixtures in food and feed: a holistic, innovative, flexible modelling approach for risk assessment MYCHIF
Mycotoxin contamination can occur in many agricultural products both destined to food and feed. Mycotoxins are produced as the result of fungal metabolism and plant-pathogen interaction. Therefore, many structurally-related congeners, defined as modified mycotoxins are generated by plant &/or fungi metabolism, or food processing, and coexist with their native forms. Studies investigating the co-occurrence of multiple-mycotoxins reported 75%100% of samples containing more than one mycotoxin, referring to native compounds and 100% reported multiple modified forms. A major challenge in a risk assessment is to depict the biosynthesis of mycotoxin mixtures and their realistic occurrence. Over th…
