During 2012, a total of 176 samples of raw milk obtained from dairy plants of Adana province of Turkey
were analysed for the presence of aflatoxin M1 (AFM1). Aflatoxin M1 analysis was carried out by
centrifugation, liquideliquid extraction, immunoaffinity column 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 0.021 mg kg1 and 0.025 mg kg1. Accuracy of the method obtained
from bias ranged from 2.94 to 8.70. Aflatoxin M1 was detected in 53 out of 176 samples analysed (30.1%).
The ranges for positive samples were 0.042e0.552, 0.033e1.01, 0.047e0.150 and 0.025e0.102 mg kg1 in
autumn, winter, spring and summer seasons, respectively. Thirty samples of raw milk (17%) were above
the legal limits of Turkey and EU regulations.
