Biosecurity Advisory 15/2021 – Fall Armyworm detected in Tasmania

A single, adult fall armyworm (FAW, Spodoptera frugiperda) was recently detected (April 2021) in a surveillance trap near Wynyard in north-western Tasmania.

FAW is an invasive tropical and subtropical pest native to the American tropics. It has rapidly spread across Australia following initial detections and establishment in the north of the country. It was first detected in far north Queensland in January 2020 and was subsequently detected in northern Western Australia and the Northern Territory before making its way south into New South Wales later in 2020 before being detected in Victoria during December 2020.

It would be possible for FAW to migrate to Tasmania from warmer areas during the warmer months due to its ability to disperse long distances on wind currents. However, due to its preference for warmer climates it is unlikely to thrive or establish permanent populations in the cool temperate Tasmanian climate.

Biosecurity Tasmania (BT) are encouraging growers and members of the public to help detect FAW by submitting suspect specimens to Plant Diagnostic Services. BT will identify suspected FAW specimens at no cost.

Visit the FAW webpage for further information including instructions on how to submit a sample.

Biosecurity Advisory 14/2021 - Revocation of Import Requirement 31(IR31) Hosts and Vectors - Citrus Canker (Xanthomonas citri subsp. citri Gabriel et al.)

Revocation of Import Requirement 31(IR31) Hosts and Vectors - Citrus Canker (Xanthomonas citri subsp. citri Gabriel et al.)

Citrus canker is a contagious plant disease that affects citrus plants including lemon, lime, mandarin, grapefruit as well as some native plant species.

In April 2018, citrus canker was detected in the Northern Territory (NT) and subsequently Western Australia (WA) in May 2018. Citrus canker had previously been declared eradicated from Australia in 2009 following an outbreak in Queensland.

Australia has once again been declared officially free from citrus canker with the lifting of remaining restricted areas in the NT from 12 April 2021, with restricted areas in WA lifted earlier.

As a result of this declaration, Tasmania has now revoked Import Requirement 31 (IR31) Hosts and Vectors - Citrus Canker (Xanthomonas citri subsp. citri Gabriel et al.) with effect from 19 April 2021.

The disease declaration has also been revoked from List A Diseases – Bacteria

Biosecurity Advisory 13/2021 - Check, Clean, and Dry your recreational equipment

Whether you are travelling to Tasmania from interstate, entering the state from overseas (such as New Zealand travellers), or moving from one area of Tasmania to another – making sure that you CHECK, CLEAN and DRY your recreational equipment is incredibly important in helping to protect the Tasmanian environment, economy, and primary industries from the harmful impacts of pests, weeds, and diseases.

Aquatic and terrestrial pests and diseases, and weed seeds can be easily spread by wet, unclean, and contaminated equipment. However, if you CHECK, CLEAN and DRY your equipment the risk of transporting these biosecurity threats can be minimised. You will also have helped to meet your General Biosecurity Duty obligations.

Examples of equipment that might be carrying biosecurity threats include (but are not limited to):

Vehicles including 4x4s, motorbikes or quad bikes, and boats/jet skis
Water sport equipment – surfboards, water skis, kayaks, diving gear
4x4 driving equipment and accessories
Fishing gear and equipment including fishing reels and waders (especially felt-soled waders – avoid using these if possible!)
Sporting equipment such as golf clubs and carts/caddies, and shoes with studs on the sole
Hiking gear including boots, backpacks, ropes, and clothing

Tasmania has world-class wilderness and recreational areas that offer amazing adventure and sporting opportunities. So before embarking on your next Tasmanian adventure or before returning home, remember to CHECK, CLEAN and DRY your recreational equipment and be ready to present your equipment to one of our Biosecurity officers for inspection on arrival into Tasmania.

Biosecurity Advisory 12/2021 – Avian influenza in poultry

Avian influenza (AI) is a highly contagious, viral disease of birds that can cause high levels of mortalities in chickens and other poultry such as turkeys and emus.

Following a response and eradication effort, Victoria’s commercial poultry flock is now free of (AI). As a result, in accordance with the World Organisation for Animal Health (OIE), Australia’s commercial poultry flock officially regained freedom from AI on 26 February 2021,

AI however remains an ongoing biosecurity threat to Australia. Tasmanian poultry producers, and bird owners are encouraged to remain vigilant for any signs of the disease.

All commercial, domestic and wild bird species are susceptible to infection, but disease outbreaks occur more frequently in chickens and turkeys. Many species of wild birds, including waterfowl (geese, ducks and swans) and seabirds, can carry the AI virus but generally show no signs of the disease. There are no treatments available for AI.

The clinical signs of AI can look similar to other poultry diseases. In general, the signs include breathing difficulties, watery eyes, bluish colouring in the comb, wattle or legs, swelling of the head, diarrhoea, nervous signs and rapid drop in water/feed intake and egg production. Bird deaths typically occur within 48 hours of infection, and sometimes less than 24 hours.

As a precautionary measure Biosecurity Tasmania encourages all bird owners to adopt simple biosecurity measures to prevent wild birds from gaining access and contaminating the food and water of poultry. AI viruses can be difficult to detect in wild birds, as they may not show signs, but can cause infections in domestic bird populations.

Feeding and watering stations should be kept in enclosed areas to limit access by wild birds. It is also strongly recommended that drinking water supplied to birds should be:

treated (chlorinated) mains water, or;
high quality bore water, or;
water treated with chlorine from other sources.

See it. Secure it. Report It.

Suspected cases of AI should be reported by calling the national Emergency Animal Disease Watch hotline on 1800 675 888. This can also be done by your veterinarian who must report any suspicion or confirmed test results.

Further information

Further information on AI, including a biosecurity checklist for bird keepers, can be found on the Biosecurity Tasmania website.

Further information on the AI response in Victoria can be found on the Outbreak website.

Biosecurity Advisory 11/2021 – Hydatids reminder: raw, untreated offal must not be fed to dogs in Tasmania.

The feeding of raw, untreated offal to dogs is prohibited in Tasmania under the Animal Health Regulations 2016 and the June 2016 Tasmanian Gazette order.

Pet food products containing raw, untreated offal need to be appropriately labelled to advise purchasers that the product is not to be fed to dogs in its current state.

Raw, untreated offal must be subjected to an approved treatment process as described in the Biosecurity Tasmania Hydatids webpage, before being fed to dogs.

If raw, untreated offal is fed to dogs, it creates a risk for hydatid infection, posing a risk for the transmission of hydatids from infected dogs to humans. Hydatid infections in people have the potential to cause serious disease and can be fatal.

It is not practical nor feasible to test for hydatids in imported or locally produced livestock animals such as sheep, cattle and goats. Though livestock infected with hydatids might occasionally enter Tasmania, Biosecurity Tasmania implements a number of measures to minimise this risk to the State including:

regular public messaging about appropriate livestock carcass disposal
border entry worming requirements for incoming dogs
information on safe dog food preparation and worming of resident dogs
reminders to practice good hygiene when handling animals or carcases
reminders to control stray dogs
a free diagnostic service for lesions in offal to facilitate any local disease control measures.

Tasmania was officially declared provisionally free of Echinococcus granulosus (the hydatid tapeworm in Australia) in dogs and sheep in 1996 and we are very fortunate to be in this situation.

There are many ways to help keep Tasmania provisionally free of this disease, and to help protect you and your family. Your cooperation and vigilance will ensure this positive situation remains.

To help raise awareness of this disease, our hydatids poster is available for download and display.

Biosecurity Advisory 10/2021 – The General Biosecurity Duty comes into effect today (31 March 2021)

From today (31 March 2021) the General Biosecurity Duty, also referred to as the GBD, will come into effect.

Tasmania’s Biosecurity Act 2019 (the Act) places an emphasis on the importance of shared responsibilities and the need for Government, industry and the community to work together, in partnership, to maintain a strong biosecurity system. The GBD, which is described within the Act, simply means that everyone has a role to play in protecting primary industries and our unique environment from biosecurity risks.

This doesn’t mean that everyone has to be a biosecurity expert, however it is important to understand and manage, or minimise, to the best of our ability, the biosecurity risks that apply to industries, businesses, workplaces, our natural environment - and in our outdoor leisure and recreational activities.

For many industries, organisations, groups and individuals, their knowledge and understanding of biosecurity risks, and their preparedness to manage and respond to those risks, is already an integral and important part of their routine activities.

The GBD now formalises related practices and actions that we can all take to help protect Tasmania’s primary industries, economy, environment and our way of life from the harmful impacts of pests, weeds and diseases.

Biosecurity Tasmania has developed a range of online resources, including stakeholder profiles and hypothetical examples, to assist everyone in gaining a greater understanding of the GBD, how simple and practical everyday actions can help everyone meet their GBD and to raise awareness of the importance for us all to work together to help protect Tasmania from pests, weeds and diseases.

Biosecurity Advisory 9/2021 – Important information regarding the 2021 release of calicivirus in Tasmania

Rabbit management requires an integrated and strategic plan of action using a range of tools and techniques.

The most effective outcomes occur when management efforts look beyond property boundaries and involve a high degree of cooperation between affected landowners, community groups and other stakeholders. Landowners have primary responsibility for managing rabbits on their land.

Calicivirus is used as one option in a suite of available management options to avoid very high rabbit population numbers.

Biosecurity Tasmania provides advice on rabbit control and regulates the annual release of calicivirus. This is because calicivirus is a biological control agent, and its effective use can be more complex than other control options.

Biosecurity Tasmania officers assess properties in response to enquiries from landowners and determine the suitability for release of calicivirus or whether other control options may be more appropriate.

What is happening in 2021?

As a consequence of the good growing conditions, this year will be a challenging year for rabbit control.

With this summer’s high rainfall, there is currently an abundance of food available, especially grass, so conditions are good for rabbits to breed and they may be less likely to take calicivirus treated bait.

Biosecurity Tasmania will continue to undertake property assessments across the state, however calicivirus release may be very limited this year given the amount of alternative feed available.

No release sites for 2021 have been published at this stage.

The release sites from last year (2020) are still available on the Department website.

If properties are assessed as suitable for calicivirus release, the areas will be listed on the Department website. Individual properties are not publicly identified.

Calicivirus is typically released during the March to July period in areas where identified rabbit numbers are problematic.

What strain of calicivirus is used in Tasmania for rabbit control?

RHDV1-K5 is the only strain released by Biosecurity Tasmania. RHDV1-K5 is a strain of the original RHDV1 virus, which was first released in Tasmania in 1997.

In 2016, a new variant of calicivirus, RHDV2, was detected in Tasmania. Previously detected on the mainland, it is not known how RHDV2 arrived in Australia or Tasmania. RHDV2 is not registered for use as a biological control agent and is NOT released by the Tasmanian Government.

How best to protect domestic rabbits?

Rabbit owners are encouraged to talk with their veterinarian regarding protection against caliciviruses. There is currently no approved vaccine available in Australia against RHDV2.

Strategies for protecting pet and farmed rabbits from caliciviruses, including important biosecurity measures, can be found on the Department website.

Where to go for more information?

Rabbit owners and landholders are encouraged to visit the Department website for more information on calicivirus and rabbit management: https://dpipwe.tas.gov.au/invasive-species/invasive-animals/invasive-mammals/european-rabbits

Biosecurity Advisory 8/2021 - Commencement of Amendments to the Cat Management Act 2009

The Tasmanian Government is strengthening Tasmania’s cat management with important changes to the Cat Management Act 2009 coming into effect from today.

Key amendments commencing today:

• A cat that is being cared for at a cat management facility must be microchipped and desexed before being reclaimed from the facility. Exemptions to microchipping will apply where a vet certifies microchipping will affect the health and welfare of the cat; exemptions to desexing will apply to cats owned by registered breeders for the purpose of breeding or where a vet certifies desexing will affect the health and welfare of the cat. The costs of microchipping, desexing and care of the cat at the facility are the responsibility of the owner of the cat.

• A person will be permitted to trap a cat on their private property, provided the trap is checked at least once within every 24-hour period after the trap is first set; and a trapped cat is either returned to its owner; or taken to a cat management facility or a nominee of a cat management facility, within 24 hours of being trapped. Arrangements should be made with cat management facilities before setting a trap.

• A person managing ‘primary production land’ or occupier of ‘production premises’ is permitted to humanely destroy a cat on ‘primary production land’ or at ‘production premises’. Persons undertaking lethal cat management action would need to comply with other relevant legislation, such as the Animal Welfare Act 1993 and the Firearms Act 1996.

The amendments deliver on recommendations for legislative change identified in the Tasmanian Cat Management Plan 2017-2022 which is Tasmania’s first comprehensive plan addressing management of domestic, stray and feral cats.

The amendments are the result of extensive consultation with industry, local government, animal welfare groups, environmental and agriculture stakeholders through the Tasmanian Cat Management Reference Group, and public feedback directly on the amendments and other processes.

Further changes will be rolled out over the next 12 months to give people time to adjust to the new requirements.

Key amendments commencing in March 2022:

• Cats over the age of four months must be microchipped and desexed.
• A person must not keep more than four cats, over the age of four months, on their property without a multiple cat permit.
• The State Government will no longer be registering cat breeders. Anyone wishing to breed a cat in Tasmania will be required to be a member of a cat organisation or will have the option of applying for a conditional permit to breed a cat.
• The option of a Care Agreement on the sale of a cat will be removed.

Biosecurity Advisory 7/2021 - Introducing the General Biosecurity Duty from 31 March 2021

Following extensive industry and community consultation, the Biosecurity Act 2019 (the Act) introduces a new legal obligation in Tasmania known as the General Biosecurity Duty, or GBD.

The General Biosecurity Duty is expected to come into effect on 31 March 2021.

The Act emphasises the importance of shared responsibilities and the need for government, industry and the community to work together to maintain a strong biosecurity system.

The GBD will operate as a statutory “duty of care” for everyone (government, industry and the community) in respect to biosecurity.

This will mean that all Tasmanians will have a duty to take all reasonable and practicable measures to prevent, eliminate, or minimise biosecurity risks when dealing with any biological matter or carrier, if they ought to know that there may be a biosecurity risk. The GBD also applies to visitors to Tasmania and to individuals and businesses who import biological material or equipment into Tasmania.

This does not mean that you need to be a biosecurity expert, however you do need to know about the biosecurity risks that apply to your specific industry, business, work environment or pastimes - and how to manage and minimise those risks to the best of your ability. For many biosecurity stakeholders, the introduction of the GBD will not change the way they go about their daily business or recreational activities.

The GBD reinforces that everyone has a role to play in protecting our unique environment and primary industries against biosecurity risks.

Understanding and meeting your GBD responsibilities will help protect your business, our primary industries, the environment and our way of life here in Tasmania.

Biosecurity Tasmania has developed a range of helpful resources to assist you to understand the GBD, to identify your GBD responsibilities to help keep Tasmania biosecurity safe.

You can find more information on the website: www.dpipwe.tas.gov.au/GBD

We all have a General Biosecurity Duty to help protect Tasmania from pests, weeds and diseases.
