In 2008, after the crisis of buffalo dairy fields in Campania, Italy, an assessment of the contamination of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (dl-PCBs) was also necessary for other animal species bred in the region. The contents of PCDDs, polychlorinated dibenzofurans (PCDFs), and dl-PCBs were determined by high-resolution gas chromatography/mass spectrometry (HR-GC/MS) (according to USEPA method 1613) in 69 sheep and goat milk samples from 63 farms. In eleven samples from six sheep farms, the PCDD/Fs levels exceeded the maximum limit of 3.0 pg g(-1) fat established by the European Commission, in particular the concentrations ranged between 3.89 and 12.90 pg g(-1) fat. Statistical treatment of the results for the congener profiles of the non-compliant and compliant samples has been used to identify the sources of contamination.
