how is the introduction of the cane toad to Queensland, Australia an example of the unitended consequences of using non native species to control pest?

According to reports, a representative from a meat processing plant will travel to China shortly to negotiate a deal to export cane toads for human consumption.

The company claims that the venom of the vilified animal is highly valued in the Asian country for its qualities as a medicinal treatment.

But in Australia, where there are an estimated 200 million specimens of the animal, it has become a major threat to native wildlife.

The poison of the cane toad, Rhinella marina, also known as the marine toad, contains toxins that in traditional Chinese medicine are used as a cardiac stimulant and as a diuretic, and is used for remedies against sinusitis and toothache.

The skin and organs of the animal are also believed to possess powerful therapeutic qualities.

As John Burey, a businessman from the northern Australian state of Queensland told the BBC, although in the country these animals are decimating wild populations, in China there is a great demand for exports of live toads, both for the amphibian meat as well as the healing properties of its venom.
