During 2016, following the implementation of a
dioxin contamination monitoring in poultry meat (ducks) in a slaughterhouse, a
positive sample was found. The investigation identified the wood shavings used
as bedding material in the duck farm as the possible source of contamination of
these animals. In this episode, contamination profiles of higher and lower
concentrations, seem to be very similar, being OCDD, OCDF and
1,2,3,4,6,7,8-HpCDD responsible for 74.4% of the total contamination of those
animals. The study revealed a reduction of poultry contamination after the
removal of the source of contamination, with an average daily depletion
percentage level ranging between 1.43% and 4.35%.
