Australia will not allow importers to irradiate imported cat food to reduce microbial hazards, according to a news  report . The decision follows reports of possible links between irradiated food and neurological damage.

Though studies have found food irradiation safe, it can reduce vitamin content. In November 2008,  University of Sydney 's Dr. Georgina Child reportedly found an association between irradiated cat food and neurological damage in cats, according to Sydney Morning Herald .

In June,  Australian Quarantine and Inspection Service  stated it would withdraw the irradiation option for imported cat food but not imported dog food.

The US  Food and Drug Administration  has approved irradiation for several types of food, including petfood, but the process is not widespread in the US.
