Tale of a bad hare day Jay Maeder US News & World Report September 15, 1997 It's a staple of countless cheesy science-fiction flicks: Scientists experiment with lethal toxic Thing, shudder, decide Thing is too dangerous to muck with, throw it back in test tube, seal it up in vault. Thing stirs. Thing escapes from laboratory, runs wild, dooms millions. This is exactly what happened in Australia two years ago, when rabbit calcivirus disease got free of its keepers and started loosing death all along the bunny trail. Re-released last fall under governmental controls, RCD is expected to wipe out 200 million Australian rabbits, to the very great satisfaction of rabbit-plagued farmers. But RCD remains banned in New Zealand, where there is also a large rabbit overrun. Three weeks ago the virus was discovered on several South Island farms, smuggled in across the Tasman Sea in violation of national biosecurity laws. As local farmers cheerfully covered their fields with the stuff--and as a Ministry of Agriculture man was accused of collaboration--horrifed officials raced to impose quarantines. Last week they admitted that eradication of the virus is impossible and began discussing possible containment. Meanwhile, little is known about RCD, and a Ministry of Health spokesman quaked that humans could be at risk as well: "You can't say anything is safe."
