"Pig meat ploy to sabotage sheep trade

Animal liberationists say they have added pig meat to the feed of sheep due to be exported to the Middle East in an attempt to stop the shipment.

The activists are trying to prevent the shipment from leaving Portland in western Victoria.

Animal Liberation's Ralph Hahnheuser says liberationists secretly added rendered pig meat to the Portland feedlot food and water delivery system overnight.

The movement is hoping its actions will taint the shipment because Muslims do not eat pigs or related products.

Mr Hahnheuser says the pig meat will not harm the animals but will stay in their system for up to 21 days, making them unfit for export to Muslim countries in the Middle East.

The port's harbour master, Captain Vejay, says a shipment of cattle already left the port this morning and a shipment of sheep is due to leave some time this weekend.

Mr Hahnheuser says liberationists are trying to contact government authorities to have them stop the shipment.

"It is our view that it would be very, very irresponsible for the
Australian Government and the export company to proceed with this shipment tomorrow morning, with the knowledge that these animals could well be rejected in the Middle East if they proceed," he said.

The owners of the Portland feedlots have denied the liberationists' claims.

They say there is no evidence to suggest the animals' feed has been tampered with and it is unlikely the sheep would eat meat products.

They say the feedlots are being guarded by security."
