During August 2002, cod liver oil was purchased from a retail outlet in metropolitan Sydney, Australia with the aim of using it as a laboratory control sample as part of the laboratory's internal quality assurance programme. The oil was analysed for polychlorinated dibenzo-p-dioxins (PCDD)/polychlorinated dibenzofurans (PCDF) and dioxin-like polychlorinated biphenyls (PCB) in parallel with spiked quality assurance samples. A mean concentration of 3.52 pg WHO-TEQDF/g fat (toxic equivalence contribution from PCDD/PCDF) was determined which exceeds the maximum limit of 2 pg WHO-TEQ/g fat for "fish oils intended for human consumption" by 75% as detailed in current European legislation (European Commission (EC) 2001).
