'Prism'
Katy Perry's 'Prism' is a biohazard in Australia.
A deluxe version of the singer's third album contains seed paper - which, when planted and watered will grow into a flower - but they coudl pose a risk to vegetation in the country, and so officials will have to inspect every case bought from online retailers in other countries and shipped over.
A spokesman for the Department of Agriculture in Australia said in a statement: "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.
"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."
Deluxe editions of 'Prism' containing the seed paper are available cheaper online from the US and other countries, but could now be seized by customs before delivery.
The company who have produced the Australian deluxe version of the album have assured officials they only contain Swan River daisy seeds from west Australia, which do not pose a threat to the country's ecosystem.
