Aflatoxin M-1 and ochratoxin A in baby formulae in Turkey: Occurrence and safety evaluation

During 2011, 62 samples of baby formulae were checked for aflatoxin M-1 (AFM(1)) and ochratoxin A (OTA) by immunoaffinity column (IAC) clean-up and high performance liquid chromatography with fluorescence detection (HPLC-FD). The limits of detection (LOD) and quantification (LOQ) of the analytical method were 0.005 mu g kg(-1) and 0.018 mu g kg(-1) for AFM(1) and 0.006 mu g kg(-1) and 0.021 mu g kg(-1) for OTA, respectively. The recovery of AFM(1) from formulae ranged between 84.27% and 88.21% (RSD = 3.54-6.18%), while the mean recoveries of OTA varied from 79.21% to 86.38% (RSD = 4.47-7.11%).
