description

The multi-mycotoxin contamination of ninety-eight (98) couscous semolina samples collected from various areas in Morocco was investigated in this study. Samples were surveyed for the presence of 22 mycotoxins (four aflatoxins, ochratoxin A, diacetoxiscyrpenol (DAS), three fumonisins, beauvericin (BEA), deoxynivalenol (DON), 15-acetyl-deoxynivalenol (15-ADON), 3-acetyl-deoxynivalenol (3-ADON), nivalenol (NIV), sterigmatocystin (STG), zearalenone (ZEA), four enniatins, T-2 and HT-2 toxins). Results showed that 96 out of 98 total couscous samples (98%) were contaminated by at least one mycotoxin. Enniatin B (ENB), Enniatin B1 (ENB1), Enniatin A1 (ENA1) and zearalenone (ZEA) have shown the highest incidences in contaminated samples. The dietary exposure was estimated to be 1.02, 0.57, 0.06, 0.57 and 0.3μg/kgbw/day for the sum of (DON+3-ADON+15-ADON), fumonisins (FB1+FB2+FB3), the sum of (T2+HT-2), NIV and ZEA, respectively.
