COMMERCIAL fishing will be banned in Sydney Harbour from this morning and anglers told not to eat their catch after tests found dangerous levels of poisons in marine life.
The tests on bream and other fish species in the Harbour found high levels of dioxins - which can cause cancer and birth defects - coming from contaminated sites at Homebush Bay.
The ban applies to the entire Harbour - from Parramatta to the Heads - and is the first ban of its kind in Sydney's history.
Recreational anglers will be told to "catch and release" all fish and signs will be posted across the Harbour.
Swimming will still be allowed as the poisons are not carried in dangerous quantities in water but concentrated in fish, making consumption potentially deadly.
Primary Industries Minister Ian Macdonald ordered the tests on fish after elevated levels of dioxins were found in prawns caught in the Harbour in December.
Commercial prawn fishing was banned at the time and an independent panel was set up to examine the situation.
That panel was meeting last night to consider the results of the latest tests before the NSW Food Authority makes a recommendation to Mr Macdonald.
Sources told The Daily Telegraph late yesterday that dioxin levels in fin fish caught in the Harbour were so high they were unsafe to eat.
Mr Macdonald was last night waiting for expert recommendations, expected early this morning, but the sources said the minister would have little choice but to stop the consumption of fish caught in the Harbour.
Another source said experts were considering telling anglers to limit consumption of Harbour fish to once a month.
"I expect that advice to include a range of options for the Government's consideration, including a possible ban on commercial fin fishing in the Harbour," Mr Macdonald said last night.
"It's important to remember that fin fish from Sydney Harbour make up less than 2 per cent of the total catch sold in Sydney."
Dioxins are passed along the food chain through a process called bioaccumulation. Because bream eat a lot of prawns, they require urgent testing.
When people eat fish contaminated with dioxins - which come from fertilizer and pesticides - the contaminants accumulate in their body tissue.
Thiess Services is cleaning up two sites at Rhodes Peninsula in Homebush Bay - including the Union Carbide site that produced Agent Orange - and that is where the dioxins have come from.
Upper House MP and medical practitioner Dr Peter Wong, who has been investigating the dioxins situation, said he was concerned for women who may have consumed Harbour fish.
"Sadly it is pregnant women and their unborn babies who are at the greatest risk from these mutagens and cancer causing chemicals," Dr Wong said.
