dc.description.abstractIn this study, a total of 110 retail cereal products from Turkey were analysed for aflatoxins (AFB1, AFB2, AFG1 and AFG2) and ochratoxin A (OTA). The mycotoxins were determined by liquid–solid extraction, immunoaffinity column clean-up and high performance liquid chromatography with fluorescence detection (HPLC-FD). Recoveries (83.9–92%) and both intra-day and inter-day repeatability (RSD < 12) of the method, meet the performance criteria set by EC regulation No. 401/2006 for the determination of the levels of mycotoxins in foodstuffs. OTA was the most prevalent toxin, with an incidence of 43.6% (range = 0.066–1.125 ?g kg?1), but at levels below the European legislation limit of 3 ?g kg?1. Aflatoxins were found in 27 of 110 analysed samples: twenty-seven samples with AFB1, fourteen samples with AFB2, seven samples with AFG1 and two samples with AFG2. The ranges for positive samples were 0.052–0.233 ?g AFB1 kg?1, 0.022–0.044 ?g AFB2 kg?1, 0.053–0.149 ?g AFG1 kg?1 and 0.033–0.037 ?g AFG2 kg?1. The co-occurrence of AFB1 and OTA was observed in 14.6% of the samples. This is the first study concerning the simultaneous occurrence of aflatoxins and OTA in retail cereal products from Turkey.
