"Opened for inspection"

I just received a brilliant care package from my sister AC that contains Japanese savoury snacks, lollies, choccies* and - for the "Naruto" fans among you - a figurine of Kakashi Hatake. Although the contents were clearly labelled, it was opened by the Australian Quarantine and Inspection Service. They didn't nick anything, and repacked and resealed the box neatly. Can't grumble about that. But I'm curious to know why they searched it in the first place. The foodstuffs are all manufactured and individually wrapped. There shouldn't have been any fishy odours to attract the sniffer beagles, which suggests the X-ray machines flagged something. Maybe they suspected the toy - which came unassembled in a "gashapon" capsule - was a ball of drugs. I guess figure collecting can be addictive...
