Summary: In 2001 we reported a study of polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDF) in eggs from poultry reared on allotments in Newcastle upon Tyne. This followed the discovery that incinerator ash (in this case a mixture of slag, bottom ash and fly ash) had been used on footpaths and in some cases within poultry pens at the allotments. Results showed PCDD/F levels well in excess of levels from barn held supermarket eggs. The congener pattern in eggs was similar to that in ash indicating a link between the use of the incinerator ash, with 17 out of 19 egg samples showing the congener pattern of ash. This follow-up investigation 20 months after the removal of ash sought to a) establish whether levels of contamination in eggs from original poultry have declined and b) ascertain that the levels of contamination in eggs from new poultry are within the expected levels for free range eggs
