In this study, a total of 40 lactating Honamlı goats aged 2-4 years in two different herds grazing on grasslands close to the district waste disposal center (Group 1; n=20) and far from the district waste disposal center (Group 2; n=20) were evaluated. Aflatoxin M1 (AFM1) levels were determined from milk serum samples of the goats. Total oxidant levels (TOS), total antioxidant levels (TAS), oxidative stress indices (OSI), and serum haptoglobin (Hp) levels were determined from blood serum samples of the goats. According to the findings, statistically significant differences (P<0.001) were determined in the comparison of AFM1, TAS, TOS, OSI and Hp values between groups. In correlation findings, a moderately significant positive correlation was found between AFM1, TAS and Hp values. In addition, a moderately significant negative correlation was found between AFM1, TOS and OSI values. As a result, it has been observed that the proximity of pastures to waste disposal centers has an effect on AFM1 levels, and AFM1 levels also affect serum TAS, TOS, OSI and Hp levels. For this reason, the edges of waste disposal centers that contain toxic and moldy products and are the source of AFM1 should be closed with wire mesh to prevent animals from grazing in such areas.
