Dioxin and PCB residues in meats from Italy: Consumer dietary exposure

In order to investigate PCB and PCDD/F concentrations and potential human health risk a study has been conducted in meat samples (beef, pork, chicken and turkey) purchased from Italian supermarkets. PCBs were dominant (41.8-77.7 ng g(-1) l.w.) with respect to PCDD/Fs (20.1-91.1 pg g(-1 )l.w.). The levels were variable and largely dependent upon the type of meat. Accumulation pattern showed a distribution typically reported for meat. PCBs tended to decrease from lowest to highest congeners, while for PCDD/Fs the concentration profile was dominated by highly chlorinated dioxins and furans. Concentrations of PCDD/Fs plus dl-PCBs and indicator PCBs exceeding the EU maximum permissible levels were found in 23.3% and 53.3% of the samples, respectively. Exposure estimates to PCDD/Fs plus dl-PCBs (0.08-4.16 pg WHO TEQs kg(-1) b.w. w.(-1)) were within the new limit proposed by the EFSA's expert panel, except for pork sausage, showing a twofold higher value. Concerning the exposure derived from indicator PCBs, the maximum level set by different European countries (10 ng kg(-1) b.w. d.(-1)) was surpassed solely via consumption of pork sausage (17.22 ng kg(-1) b.w. d.(-1)), thought also the estimated intake from hamburger consumption (6.88 ng kg(-1) b.w. d.(-1)) merits attention being close to guideline limit.
