Abstract
Sixty-eight samples of cereals products, including breakfast cereals ( n = 48) and infant cereals ( n = 20), purchased from supermarkets and pharmacies in Rabat-Salé area from Morocco were analysed for the determination of six emerging mycotoxins: four enniatins ENs (ENA, ENA1, ENB and ENB1), beauvericin (BEA) and fusaproliferin (FUS). Samples were extracted with a mixture of acetonitrile:water (85:15, v/v), using an Ultra-Turrax® homogeniser. Mycotoxins were then identified and quantified by liquid chromatography (LC) with diode array detection (DAD). Positive samples were confirmed by LC–MS/MS. Analytical results showed that the percentages of analysed samples contaminated with total ENs, FUS and BEA were 30.8%, 10.3% and 5.8%, respectively. ENA1 was the mycotoxin most often found: ENA1 levels ranged between 37.5 and 688 mg/kg. FUS and BEA were present in levels lower than 7.4 and 10.6 mg/kg, respectively. This is the first international report on the presence of emerging Fusarium mycotoxins in breakfast cereals and infant cereals.
