Two horses on the Rockhampton, Queensland, Australia, property where a horse died of hendra virus last week returned positive test results today (June 5).

Biosecurity Queensland Chief Veterinary Officer Rick Symons, BVSc, MBA, PhD, said the two horses would be retested to confirm the results before a decision was made about future action. There are eight horses in total on the property.

"It is likely that the animals in Rockhampton contracted the disease from the originally infected horse which died last week," Symons said.

In addition, Biosecurity Queensland officers will be retesting a dog on an Ingham, Queensland, property on which a horse was confirmed hendra-positive last week after the dog returned a weak positive test result
