Hippy chic Katy Perry’s bid to “spread the light” by giving away seed paper with her new album Prism has run into a small problem with agricultural officials Down Under.

It seems her kind gesture risks damaging Oz’s delicate ecology and is causing a genuine "bio-security concern".

Australia’s Department of Agriculture believes that the seed paper which grows when planted that Perry has given away with a deluxe version of Prism could pose a risk to the country.

Now security officers have been ordered to inspect new copies of the album arriving from abroad.

Perry encouraged fans to plant the seeds and "spread the light" via her Twitter page but strict custom laws mean that copies of Prism arriving in Australia could be confiscated by border control, as plant materials from outside the country must be thoroughly assessed before entry.

"Seeds or plant material of international origin may be a weed not present in Australia or the host of a plant pathogen of bio-security concern,” a Department of Agriculture spokesperson told news.com.au.

"Our bio-security officers at international airports, seaports and mail centres assess the risks associated with various items every day and are well-trained in making informed decisions about whether items could be of bio-security concern."
