Panama disease

Biosecurity Queensland has confirmed that Panama disease tropical race 4 is present in north Queensland.

If you believe you have plants infected with Panama disease tropical race 4, call Biosecurity Queensland immediately on 13 25 23.

Current situation

Panama disease tropical race 4 was initially detected on Cavendish banana plants on a farm in the Tully Valley, North Queensland, on 3 March 2015

Panama disease suspected on another property in the region

Samples taken from banana plants on another property in the Tully Valley have returned a positive initial molecular (PCR) test for Panama disease tropical race 4.

A range of diagnostic tests is yet to be completed by the Plant Biosecurity Laboratory in Brisbane and until all tests are complete a final conclusive result cannot be confirmed.

The suite of tests will take up to 4-6 weeks to complete.

The property owners are working with Biosecurity Queensland to control and contain any disease to mitigate the risk of further spread. The property owners are exceptionally proactive and already have strict on-farm biosecurity measures in place on their property.

Biosecurity Queensland will be working with the owners and the peak industry body, the Australian Banana Growers’ Council (ABGC), to provide support and advice as required.

Prompt reporting of plants with suspected symptoms of Panama disease is a legal requirement, and critical to successful containment of the disease. Early detection and destruction of infected plants helps to slow any spread.

Growers are urged to maintain their on-farm biosecurity to protect their properties from Panama disease tropical race 4.

As the disease is spread through soil, mud and infected plant material, it is essential that people, vehicles and machinery and equipment are appropriately decontaminated on property entry and exit.

If you suspect Panama disease in your plants, report it immediately to Biosecurity Queensland on 13 25 23.

Managing the affected farm

The only known Panama disease tropical race 4 affected property in Queensland was purchased under an industry levy with additional Commonwealth funding by the ABGC. The sale of the property was settled in October 2016; the ABGC took ownership of the affected property and immediately ceased all farming operations.

The Queensland Government has provided almost $400,000 to the ABGC to assist with the closure of the affected farm. This latest funding is being invested in strengthening the current perimeter fence, destruction of the remaining banana plants on the affected property and establishing a ground cover to prevent run-off.

Biosecurity Queensland confirmed detections of Panama disease tropical race 4 on nine (9) separate areas of the affected property prior to its closure. All plants that return positive test results for the disease, as well as a buffer of plants around the infected plants are destroyed using a technically appropriate strategy. ABGC field officers completed destruction to remove all the remaining banana plants on the 350 acre property.

Although Biosecurity Queensland has ceased surveillance on the affected property, the program is still heavily involved with the ongoing management of the property in line with the requirements of the Queensland Biosecurity Manual.

Biosecurity Queensland are now visiting all commercial banana farms in the region to further safeguard the industry against Panama disease tropical race 4. Previously, surveillance teams only visited farms with traced links to the affected property. The disease has not been detected on any other property.

Growers should not become complacent with the recent closure of the affected farm. Panama disease tropical race 4 is still viable after 40 years in the soil without a host plant, so there is a possibility the disease is lying dormant as yet undetected.

Since March 2015, over 1,537 suspect plant samples for Panama disease tropical race 4 have been processed by the Biosecurity Queensland laboratory.

Biosecurity Queensland's overall program of surveillance and containment, in partnership with industry is continuing. Growers should continue to focus on strengthening their on-farm biosecurity practices to protect their businesses.

The Biosecurity Act 2014 (the Act) came into effect from 1 July 2016. Under the new legislation, restrictions continue to apply to affected properties and properties suspected of having Panama disease tropical race 4.

In Queensland, under the Act, Panama disease tropical race 4 is category 1 restricted matter. This means that, by law, plants showing signs of disease must be reported to Biosecurity Queensland on 13 25 23.

On 10 February 2016, the Queensland Government released an independent report undertaken by Deloitte Touche Tohmatsu (PDF, 2.6MB) into testing procedures for Panama disease tropical race 4 after test results from a Mareeba banana farm in 2015 were found to be a ‘false positive’. The Deloitte review assessed the adequacy of testing processes from end to end including sampling and diagnostic assessment processes, associated reporting and response activities.

The review determined one of the key diagnostic tests was unreliable and confirmed that no human error occurred, all policies and procedures in relation to Panama disease testing were followed by staff and all reasonable steps were taken to verify this test result.

While the review found all procedures were followed, the report made a number of recommendations to further enhance laboratory practices and quality assurance, which included changes to organisational structure, management information systems and documentation. This feedback is valuable as part of DAF's commitment to continuous improvement and the Department is considering what measures can be implemented.

Queensland's current Panama disease testing procedures have been confirmed as being accurate and reliable with two independent laboratories verifying the Panama TR4 Program's results and findings. The Royal Botanic Gardens laboratory in Sydney and Stellenbosch University in South Africa, have conducted their own tests of suspect samples taken from the known infested banana farm near Tully and arrived at the same uniformly positive results. Both laboratories are internationally recognised for their research into Fusarium; the group of fungi which can cause Panama disease.
