Abstract :In the study, AFB 1 and total aflatoxin levels of roughages and concentrates from twenty dairy farms in Hatay, AFB 1 carry over rate (CO) from feed to milk as AFM 1 and correlation between total aflatoxin intake and blood parameters were investigated. In none of the roughage samples, AFB 1 levels was over 5 ppb while the concentrates of 9 farms were found to be above 5 ppb legal limit. The average AFB 1 levels of concentrates and roughages, and the average AFB 1 intake were 4.496 ppb, 1.282 ppb and, 15.987 μg/day, respectively. A total of one hundred milk samples were collected by taking five dairy cows from each farm. The two of milk samples were found to be exceeded the level of 0.05 ppb of the AFM 1 level that is the statutory limit in Turkey. The average AFM 1 level of the farms was 0.0214 ppb and none exceeded the legal limit. The average CO rate of farms was found to be 2.66%. The correlation coefficients were not significant between total aflatoxins intake and blood parameters. As a result, the AFM 1 excretion in milk was related to AFB 1 intake and milk yield. In dairy cows, a daily intake of AFB 1 37.3 μg at maximum level should not be exceeded to stay in the statutory limit for AFM 1 in milk.
