A survey of 150 sunflower-seed samples was carried out to evaluate the contamination from infection with Alternaría alternata with alternariol (AOH), alternariol monomethyl ether (AME) and tenuazonic acid (TA). A high percentage of the samples was contaminated with AOH (85%), AME, (47%), and TA (65%). The average levels detected were 187 µg/kg for AOH, 194 µg/kg for AME, and 6,692, µg/kg for TA. When sunflower seeds fermented by Alternaría alternata were processed under laboratory conditions to obtain the oil and meal, different distributions of Alternaría toxins between the oil and the meal were observed: whereas AOH, AME, and TA were detected in the meal, only AME and TA were detected in the oil, and the latter in a low percentage
