Anthrax was not the cause of cattle deaths on a property in the Stanthorpe district this week, testing has revealed.
A Biosecurity Queensland spokesman said initial testing has ruled out the possibility of anthrax.
"Further testing is underway to identify the exact cause with results not expected until next week," he said.
"Graziers should have a biosecurity plan in place and consult with their local veterinary practitioner to decide what specific measures they can take to protect their livestock and property against diseases or biosecurity risks.
"Graziers should always monitor the health of their stock and immediately seek veterinary advice in the event of sudden deaths."
In a statement, the Southern Downs Regional Council urged residents to avoid speculating on the deaths until all tests had concluded, because of the potential impact on people in the region.
Unexplained deaths of animals should be reported to Biosecurity Queensland on 13 25 23.
