Treść
Dried feed materials, such as sugar beet pellets, may be a source of high levels of PCDD/Fs. Thestudies followed up dioxin congener elimination from contaminated milk (5.02 ± 1.39 pg WHOPCDD/F-PCBs-TEQ g−1 fat) up to 338 days after withdrawal of polluted feed ingredient(4.37 ± 0.25 ng PCDD/F/DL-PCBs-TEQ kg−1 feed). The main objectives of the study were toestimate the length of the time needed to achieve an acceptable PCDD/F milk level as set byEuropean Union law, to track the fate of the PCDD/F congeners, and to assess the potential riskfor consumers associated with long-term consumption of contaminated milk. After approximately200 days, the PCDD/F levels reached ML (2.5 pg WHO-TEQ g−1 fat), then decreased to the actionlevel after more than 300 days (1.75 pg WHO-TEQ g−1 fat) for most of cows. The potential risk ofPCDD/F/DL-PCBs intake was characterised by comparing the theoretically calculated weekly andmonthly intakes with the toxicological reference values (TRVs). The dioxin intake for the averageadult and high-milk consumers did not exceed half of any of the TRVs applied (TWI, PTMI). Theconsumption of milk by children in the amount recommended by nutritionists (500 ml day–1)resulted in an exposure equal to 317% TWI and 275% PTMI.
