Vigilance Urged: Protecting Victoria from Red Imported Fire Ants

Importance of Biosecurity for Farmers

Agriculture Victoria has issued a crucial reminder for farmers to remain vigilant regarding import requirements and to monitor for the presence of Red Imported Fire Ants (RIFA) when sourcing fodder from other states. Stephen Dibley, Acting Chief Plant Health Officer for Agriculture Victoria, emphasizes that RIFA, scientifically known as Solenopsis invicta, ranks among the most invasive ant species in Australia.

Background on Red Imported Fire Ants

Initially identified in Brisbane in 2001, RIFA is native to South America and remains primarily localized within the Greater Brisbane area. However, recent findings have confirmed its presence in two additional zones in New South Wales.

“RIFA is not present in Victoria, and our goal is to maintain this status,” stated Dr. Dibley. “The introduction of RIFA into Victoria could have devastating impacts on the economy, agriculture, environmental stability, and the health of both people and livestock.”

The Risk of Inadvertent Importation

As drought conditions compel farmers to source hay and fodder from interstate suppliers, the risk of unknowingly importing RIFA increases significantly. Dr. Dibley underscores the importance of caution, stating that RIFA often travels on materials moved out of infested areas.

“With current circumstances, farmers are likely dealing with unfamiliar fodder suppliers, creating a need for heightened biosecurity awareness,” he added.

Guidelines for Purchasing Fodder

Farmers must recognize that any hay or straw acquired from outside Victoria requires documentation proving it originates from a RIFA-free area. Specifically, materials sourced from infested zones must adhere to inspection and treatment standards, certified by the respective agricultural authority of the issuing state or territory.

Certificates required for such purchases include:

• Plant Health Certificate (PHC)
• Plant Health Assurance Certificate (PHAC)
• Biosecure HACCP Biosecurity Certificate (BHBC)
• Plant Health Declaration (PHD)

Reporting Suspected Findings

If you suspect RIFA presence, it is imperative to report your findings without delay. This can be done via the Agriculture Victoria Public Online Reporting Form at agriculture.vic.gov.au/biosecurity/pest or by contacting the Exotic Plant Pest Hotline at 1800 084 881.
