- Abstract
Twenty two mycotoxins in 136 durum wheat collected from Tunisia in 2020 and 2021 were investigated. Mycotoxins were analyzed by UHPLCMS/MS. In 2020, 60.9% of the samples were contaminated with Aflatoxin B1 (AFB1) and/or enniatin. Whereas, in 2021, 34.4% were contaminated by enniatins. AFB1 was detected only in 2020, in the continental region (6/46) and all samples exceeded limits. AFB1 was detected in stored wheat (24-37.8 µg/kg) but also in pre-stored wheat (17-28.4 µg/kg) and in one sample collected in the field (21 µg/kg). Enniatin A1, enniatin B and enniatin B1 were detected in wheat collected in the field (30-7684 µg/kg), pre-storage (42-1266 µg/kg) and storage (65.8-498.2 µg/kg) from the continental region also, in sample collected in pre-storage (31.3-1410 µg/kg) and at harvest (48- 1060 µg/kg). Samples had a water activity less than 0.7 and moisture content ranged between 09-14%. AFB1 level represent a health risk to the Tunisian consumers.
