ABSTRACT: During 2006 and 2011, following the implementation
of dioxin contamination monitoring in poultry meat, levels higher than legally
allowed in meat from poultry slaughtered for human consumption, were found. The
wood shavings used as bedding material in the poultry farm showed considerable
high contaminations, indicating that these materials were the likely source of
contamination of the animals. Wood shavings samples (n = 23), used as poultry
litters in intensive farms of broilers, were analysed. In both episodes,
contamination profiles of higher and lower concentrations, seem to be very
similar, being OCDD, OCDF, 1,2,3,4,6,7,8-HpCDD and 1,2,3,4,6,7,8-HpCDF
responsible for 97.4 % of the total contamination. The present work describes
the analytical adapted, used methodology and the specific clean-up procedures, which revealed that recoveries of 13C12-Labelled
compounds added to the wood shavings samples ranged from 71.3% to 86.3%.
