| Abstract: | The occurrence ofAlternaria mycotoxins was investigated in 80 samples of tomato puree processed and sold in Argentina. Alternariol (AOH), alternariol monomethyl ether (AME) and tenuazonic acid (TA) were searched for by liquid chromatography. Thirty-nine of the 80 samples showed mycotoxin contamination. TA was found in 23 samples (39-4021 μg/kg), AOH in 5 samples (187-8756 μg/kg), and AME in 21 samples (84-1734 μg/kg). Co-occurrence of two of these toxins was detected in 10 samples. This is the first report of natural occurrence of AOH, AME and TA in tomato products in Argentina. |
