Chlorinated dibenzo-p-dioxins, chlorinated dibenzofurans, and pentachlorophenol in Canadian chicken and pork samples
Analysis of 144 chickens and pork tissue samples for pentachlorophenol (PCP) showed more than 60% of fat samples contained greater than 10 parts per billion (ppb; ng/g) PCP while chicken liver had a lower (27%) incidence of positives, and all pork livers contained values over 50 ppb. With the use of new methodology capable of determining all tetra- to octachlorinated dibenzo-p-dioxins (CDDs) and chlorinated dibenzofurans (CDFs), the incidence of positives in selected samples of chicken fats for hexa-, hepta-, and octachlorinated CDDs was 50, 62, and 46% with averages of 27, 52, and 90 parts per trillion (ppt; pg/g), respectively. Similar levels of hexa- and heptachlorinated CDFs were also found in some of these samples but tetra- and pentachlorinated CDDs and tetra-, penta-, and octachlorinated CDFs were not detected. A comparison between the chicken tissues and PCP-treated wood with regard to specific isomers and congeners of CDDs and CDFs and their relative proportions showed a marked similarity, indicating that PCP was the source of contamination of the food samples.
