Abstract
In this study, 64 samples of raw cereals (wheat, maize and barley) purchased from local markets in Rabat-Salé area from Morocco were analyzed for the occurrence of six emerging mycotoxins: four enniatins ENs (ENA, ENA1, ENB and ENB1), beauvericin (BEA) and fusaproliferin (FUS). Samples were extracted with a mixture of water/acetonitrile (85/15, v/v) by using an Ultra-turrax homogenizer. Mycotoxins were then identified and quantified with a liquid chromatography (LC) with diode array detector (DAD). Positive samples were confirmed with an LC-MS/MS. Analytical results showed that the frequencies of contamination of total samples with ENs, BEA and FUS were 50, 26.5 and 7.8%, respectively. ENA1 was the most common EN found with a percentage of contamination of 39%, levels ranged between 14 and 445Â mg/kg. ENB contaminated 14 samples (21.8%) and levels ranged from 5 to 100Â mg/kg. ENB1 was present in four samples (6.2%) and levels varied from 8 to 32Â mg/kg. ENA was detected in only one sample with 34Â mg/kg. BEA levels ranged from 1 to 59Â mg/kg and FUS levels varied from 0.6 to 2Â mg/kg. The present report is the first one ever drafted on the presence of emerging Fusarium mycotoxins in raw cereals available in Morocco.
