Australia worried Katy Perry's CD is a biohazard

Katy Perry Topless in Rolling Stone

The outrageous songstress likes getting sexy, doesn't like casual sex.

Biosecurity officers have been directed to inspect Katy Perry CDs purchased overseas due to fears they may pose a risk to Australia.

The deluxe version of the U.S. singer's new album PRISM contains a small packet of seeds.

While the production company has assured the Department of Agriculture that the Australian release contains locally sourced seeds, international versions of the album still pose a risk.

"Seeds or plant material of international origin may be a weed not present in Australia or the host of a plant pathogen of biosecurity concern," a department spokesperson said.

It is understood the Australian release contains harmless local Swan River daisy seeds.

But a spokesperson said further inquiries were being made regarding international versions.

"The Australian Government has a strong system in place to detect and respond to material of biosecurity concern. This includes the inspection of mail, cargo and baggage."
