4. Conclusions
AFM1 levels exceeding the EU MRL values were determined in a total of 27.8% of raw and 9.64% of UHT samples. In samples collected during February, March, May and June, statistical differences in mean AFM1 concentrations were observed between raw and UHT milk samples. In both raw and UHT milk samples, AFM1 concentrations gradually decreased in the period from May to July. The incidence of lower AFM1 concentrations in the summer period in this study confirmed the use of fresh raw feed such as pasture and grass instead of concentrated feed. Regarding the present results, the most effective control of raw materials and supplementary feedstuffs for dairy cattle is required, especially in accordance to the climatic conditions of the current year.
