Horse meat is characterized by high nutritional value, but due to the specific physiology and long lifespan of horses, it represents a significant pathway for the bioaccumulation of toxic elements. The aim of this study was to examine the presence of cadmium (Cd) and lead (Pb) in muscle, liver and kidney samples of horses slaughtered in Serbia during 2023 and 2024. The toxic elements were determined by flame atomic absorption spectrometry (FAAS). The mean concentrations of cadmium and lead were 0.19 and 0.51 mg/kg in horse muscle; 2.31 and 0.74 mg/kg in horse liver; and 7.70 and 0.68 mg/kg in horse kidneys. Statistically significant differences in mean concentrations were observed between horse tissues, seasons and different age categories (p 0.05). Cadmium levels were above the maximum permitted limits in 93.2% of liver samples, 97.7% of kidney samples, and 31.1% of muscle samples tested. The data obtained indicate the need for continuous monitoring and strict control of animal traceability, especially those raised near ecological hotspots.
