After a foreign horse tested positive for the horse flu on Wednesday night, ABC News reports that horse racing authorities tested 74 horses at Sydney’s Eastern Creek Quarantine Station and found no trace of the virus.
Additional testing showed that the foreign horse had tested a false positive, according to Peter Vlandys, the chief executive of Racing New South Wales.
"All 74 horses have been tested and have all come back negative, so it's a sigh of relief for all those in the quarantine centre and the racing industry in particular," Mr. Vlandys told the news outlet.
In August 2007, an equine influenza outbreak drove the Australian government to put the multi-billion dollar industry on lockdown.
