Sažetak
In this study, the concentrations of metals (arsenic (As), cadmium (Cd), copper (Cu), mercury (Hg) and lead (Pb)), and aflatoxin M1 were analysed in mare's milk samples taken from eight mares over a period of six months during lactation. The results showed that the concentrations of metals in milk occurred in the following order: Cu > Pb > Hg > Cd > As. Key findings of the study included the determined content of metals, depending on lactation stages and animal husbandry practices. Copper had the highest concentration among the metals analysed, while Cd and As were not detected. No statistically significant differences were found in the levels of heavy metals or aflatoxin M1 across different lactation stages. However, statistically significant differences in aflatoxin M1 concentrations were observed depending on the type of animal husbandry, illustrating the influence of environmental and husbandry conditions on milk contamination. The study concludes that there is no toxicological risk for consumers of Croatian Cold-Blooded mare's milk, which is an important finding for food safety and public health. The significance of this study lies in the provision of valuable data on the safety of mare’s milk, especially with regard to its possible contamination with toxic heavy metals and aflatoxin M1. The main objective was to determine the presence and concentrations of the listed contaminants, to evaluate the influence of lactation stage and husbandry, and to assess compliance with established safety standards.
