An official monitoring programme was started in 2006 with the aim of estimating the concentrations of PCDD/Fs, dl-PCBs, and ndl-PCBs in raw cow's and goat's milk. A random sampling scheme was applied to selected voivodeships. The average concentration of dioxins and furans in cow's milk was 0.88 and 1.46 pg WHO-TEQ/g fat in goat's milk. The mean dioxin-like PCBs concentrations were 0.58 and 0.76 pg WHO-TEQ/g fat; subsequently the WHO-PCDD/F-PCB-TEQ were 1.47 and 2.22 pg/g fat for cow's and goat's milk, respectively. The mean concentrations of PCDD/Fs and dl-PCBs in cow's milk samples were in the range of ¼ of the maximum levels established in European Union. The mean ndl-PCBs concentrations were 1.27 and 1.59 ng/kg fat for cow's and goat's milk, respectively, well below recently-discussed maximum levels.
