Abstract:To assess public health hazards associated with the occurrence of AFM1 residues in pasteurized milk and UHT milk a survey was carried out, in Prishtina, capital city of Kosovo. In the present study, a total of 178 samples, 84 pasteurized milk and 94 UHT milk were collected during 6 months (July to December 2013). They were obtained from retail outlets in Prishtina city (Kosovo). The occurrence and concentration range of AFM1 in the samples were investigated by competitive enzyme-linked immunosorbent assay (ELISA) method. There was a high incidence of AFM1 (81.0%) in both pasteurized and UHT milk samples. Eighty three percent (83.3%) of the pasteurized milk samples and seventy eight percent (78.7%) of the UHT milk samples contained AFM1. The positive incidence of AFM1 in the pasteurized milk and the UHT milk samples ranged from 5.16 to 110 ng/L and from 5.02 to 62 ng/L, respectively. AFM1 levels in 18 (21.4%) pasteurized milk samples and 4 (4.2%) UHT milk samples exceeded the maximum tolerable limit of the EC according to the European Union regulation limits of 50 ng/L. AFM1 levels in the samples show that there is a presence of high AFM1 level that constitutes a human health risk in Kosovo. The results of this study imply that more emphasis should be given to the routine AFM1 inspection of milk and dairy products in the Prishtina region.
