You'd be amazed what some people try to bring into the country.

A barbequed rat, goat foetuses, duck tongues and lizard's feet were among 340,000 items confiscated at the border last year, according to the latest data from the Department of Agriculture and Water Resources.

Nearly a third of the items were seized at Sydney Airport.

They included 20,000 kilograms of meat, about 7,000kg of seafood, 3,000kg of seeds and 2,000kg of bananas.

Minister for Agriculture and Water Resources David Littleproud said biosecurity officers shouldered a big responsibility.

"Any one of the items could cause devastation to the agriculture industry, the environment or humans, through disease," he said.

"Agriculture, fisheries and forestry employ more than 300,000 Australians, put $63 billion into the economy and supply 93 per cent of domestic food, according to the National Farmers' Federation," he said.

Among the other unusual items intercepted at Sydney Airport, were cooked eggs, chickens' feet and skinned frogs.

Mr Littleproud thanked the biosecurity team at Sydney Airport for working to keep Australia safe from bio threats.
