Dioxins, which can also be formed by natural processes, were found in all sediment testing sites at levels that have not raised officials’ concerns to date.
The report said Queensland Health believed eating fish from the Noosa area “is unlikely to result in an unacceptable risk to public health” for recreational fishers and advises against issuing public advice on the safe levels of local seafood consumption.
However further studies are planned for the local commercial fisheries with the report saying these dioxin levels were also not expected to be of concern.
Mr Alexander, 47, who is based at Tin Can Bay but chases the mullet run usually around the mouth of the Noosa River and north shore, was unaware of the ongoing investigation.
