'Toad juice' buyers warned of explosion risk

The makers of a liquid fertiliser made from pulverised cane toads have issued a warning that the "toad juice" bottles could explode.

Northern Territory FrogWatch sold 300 bottles at Darwin's recent Garden Spectacular but says the liquid in the batch is still fermenting.

It has asked customers who have not used their bottle to move the cap half a turn to ease the pressure or risk getting showered by an evil-smelling sticky liquid.

Graeme Sawyer, from FrogWatch, says the liquid is no longer poisonous.

"There's no toxin left in it by the time it's been through the fertiliser process," he said.

"It's an inert substance in that sense, so there's no problem there.

"The issue just is that because it was such a fresh batch, it's still producing gas.

"If you've got it in the bottle and the lid's sealed tightly, it builds up pressure in the bottle."
