dc.description.abstractAflatoxin contamination of milk in the Greater Addis Ababa milk shed Ethiopia was reported in 2016, indicating a that high probability of contamination of milk corning from the surrounding areas of Addis Ababa. Therefore, the objective of this study was to investigate the occurrence of aflatoxin M1 (AFM1) in milk and dairy products (cheese butter and yogurt) in Bishoftu (Ethiopia). The effect of different dairy production processes to the concentration of AFM1 was also investigated. In addition, KAP (Knowledge attitude and practice) study was conducted on local producer and on employees from dairy industries. Milk (n=108), cheese (82), yogurt (93) and butter (82) samples were taken from both industrial and local producers by purchasing from their shops and the level of AFM1 was determined using ELISA (Enzyme Linked Irnmuno Sorbate Assay) method. From 366 samples analysed 361 samples were found positive and the maximum value of aflatoxin among all the analyzed samples was found in cheese which is 5.580+0.08I-'g/kg and the minimum (Not detected) in butter. Under comparing the mean values of each dairy product type of local products with the industrial products all the industrial products have a higher mean value r~lative to the local one. In addition to this the KAP study shows though the local producers had knowledge on mycotoxin related questions their knowledge specific to AFM1 practice towards reducing the contamination level of AFM1 is not enough. But they have a positive attitude towards reduction of AFM1 level. Unlike the local producers employees in dairy industry had a better practice towards reducing the level of AFM1 contamination. Even though researches have been done about level of AFM1 in milk so far, this shldy shows that the problem on the occurrence of the toxin s till persists. Therefore, the government should establish a program to regularly cheek AFM1 levels and take corrective mitigation measures. Key words: Aflatoxin Ml, Milk, Cheese, Yogurt, ELISA, KAP assessmenten_US
