Tasmanian Biosecurity Advisories
Department of Primary Industries, Parks, Water and Environment
Subscribing to get DPIPWE’s Biosecurity Advisories is the best way you can keep yourself up-to-date and fully informed about Tasmanian biosecurity issues. Our Advisories cover topics such as changes or proposed changes to Tasmania’s import regulations, animal health and welfare, plant health, forthcoming regulation reviews and opportunities for public comment, new or emerging pest/disease risks and a range of other matters related to Tasmania’s biosecurity.
Fruit fly was detected in northern Tasmania in January 2018. Part of the control and eradication actions in response to the fruit fly detection included the declaration of temporary Control Areas and Infected Areas, enforcing restrictions on host produce moving in and out of these areas.

Following the recent detection of soft-shell clams in Orford, Tasmania and in accordance with Section 270 of the Living Marine Resources Management Act 1995, Fisheries (Biosecurity) Order 2018 No.2 was gazetted today, Wednesday 11 July 2018.
This order may be cited as the Fisheries (Biosecurity) Order 2018 No. 2.
This order is made – (a) in respect of the harmful pest the soft-shell clam Mya japonica; and (b) to place restrictions on the take and possession of that harmful pest to control and prevent the spread and introduction or re-introduction of Maya japonica into areas of State waters.
(1) That, unless otherwise authorised, a person must not take Mya japonica in State waters.(2) That, unless otherwise authorised, an unauthorised person must not possess Mya japonica.
"unauthorised person" means any person who is not an employee of the Department of Primary Industries, Parks, Water and Environment or the Tasmanian Museum and Art Gallery undertaking research or biosecurity activities on the soft shell clam Mya japonica.

Biosecurity Tasmania wish to advise that Import Requirement 46 relating to hosts and vectors of tomato potato psyllid (Bactericera cockerelli (Šulc) (syn. Trioza cockerelli Šulc)) has been formally declared on 8 June 2018. This import requirement is in response to the detection and establishment of tomato potato psyllid (TPP) in the Perth metropolitan area, Western Australia, and as a precautionary measure in the event the psyllid is detected in other parts of Australia.

Biosecurity Tasmania urges owners of sheep to be vigilant for any signs in their flock of cold stress brought about by forecast cold conditions and heavy rains. Sheep recently shorn and new lambs could be suffering due to the weather conditions and all reasonable precautions should be taken to minimise the effects of cold stress.
Sheep have a natural insulation to extreme weather with their fleece. In cold, wet and windy conditions, sheep shiver, huddle together in the mob and seek shelter behind windbreaks to produce and conserve heat. However, these mechanisms have limits. If weather stress is excessive or prolonged, the sheep's capacity to maintain a stable body temperature may be exceeded and cold stress will result. Hypothermia most commonly occurs in freshly shorn, light condition sheep during wet and windy conditions at any time of the year
Hypothermia literally means 'temperature below normal', occurs when too much body heat is lost or too little body heat is produced, and the result is a drop in body temperature. If weather stress is excessive or prolonged, a sheep's capacity to maintain a stable body temperature may be exceeded, and heat or cold stress will result.
High rainfall and high winds combined with temperatures below normal will cause mortalities in young animals, especially newly shorn sheep without shelter. The impact of the cold weather will depend on its duration, rainfall, wind speed and temperature—the 'wind chill' factor can double heat loss.
Sheep suffering from hypothermia often die as a result of their own behaviour and their attempts to cope. Sheep move in the direction of the wind until they are stopped by a barrier such as a fence, gully or creek. At this point they may pile on top of each other leading to suffocation or drowning. Sheep may be reluctant or unable to move when wet and cold.
Initially sheep will try to maintain their body temperature by:
If dealing with a small flock, consider applying garbage bags as coats for the sheep. Trials have shown that properly fitted plastic bags can decrease the loss of body heat even in severely hypothermic sheep.
Be prepared to relocate animals to a shed or land on higher ground, or move stock to paddocks with adequate windbreaks with tree or bush shelter in the event of very heavy rainfall or likely flooding.
Prioritise your animals, giving shelter to the most vulnerable such as the ewes and lambs and those newly shorn.
The Bureau of Meteorology have issued a flood watch for low lying / flood susceptible areas on Tasmania's east coast, advising graziers that they should prepare to move stock in expectation of heavy rainfall.

A major effort is being undertaken to eradicate fruit fly from Tasmania.

Citrus canker (Xanthomonas citri susbp citri) has recently been detected in the Northern Territory. Citrus canker is a serious disease of citrus and can have severe impacts on fruit quality and yield. Citrus canker is not harmful to people or animals.
Biosecurity Tasmania has declared citrus canker to be a List A disease under the Plant Quarantine Act 1997 and has re-instated the Import Requirement on the import of Citrus plants and plant products (including leaf material and fruit) as well as agricultural equipment and machinery that may have been in contact with the disease.
Find the re-instated Import Requirement 31 on the Biosecurity Tasmania website at: www.dpipwe.tas.gov.au/biosecurity-tasmania/plant-biosecurity/plant-import-restrictions
Citrus canker has been detected in Australia previously and been successfully eradicated.
For more information on citrus canker, signs and symptoms, visit the NSW Department of Primary Industries website at: www.dpi.nsw.gov.au/biosecurity/plant/insect-pests-and-plant-diseases/citrus-canker
Furher information can also be obtained at the Outbreak website: www.outbreak.gov.au/current-responses-to-outbreaks/citrus-canker
If you think you have seen symptoms that look like citrus canker, call the Plant Pest Hotline on 1800 084 881
