Poisonous sausages containing toad meat are being trialled in the Kimberley to try and protect native animals from cane toads' deadly impact.

The Western Australian Department of Environment and Conservation has been working with the University of Sydney to develop baits to train native animals not to eat the toads.

By blending bits of toad with a nausea-inducing chemical, the baits train the animals to stay away from the amphibians.

Researcher David Pearson says trials run in laboratories and in remote parts of the Kimberley region of WA are looking promising, although the baits will not solve the cane toad problem altogether.

"It would be impossible to put baits out right across the country," he said.

"I can tell from blending up dead toads in a sausage maker, it's a lot of work, so it's not something we could readily do right across the landscape.

"But it does allow us to lay baits in those areas which are of particular importance and train the animals not to eat the toads."

Cane toads have crossed the border into the Kimberley from the Northern Territory.

They were introduced to Queensland in 1935 to control sugarcane beetles.
