Biosecurity Advisory 28/2018 – Revocation of IR 25: Green Snail – Vector Import Controls

​An Import Risk Analysis (IRA) was conducted in 2018 on the potential threats posed to Tasmania by the green snail (Cantareus apertus). This is part of Biosecurity Tasmania’s plant biosecurity risk analysis program, which identifies and reviews pest risks that may present a threat to the State in association with the daily trade of goods, services and movement of people. The Green Snail Import Risk Analysis is now available on the Biosecurity Tasmania website

The risk analysis has resulted in the risk rating of green snail being amended from the status of a List A ‘Regulated Quarantine Pest (RQP)’ (as declared under Section 12 of the Plant Quarantine Act 1997), to that of an ‘Unwanted Quarantine Pest (UQP)’ which better aligns with the biosecurity risk the snail poses to Tasmania. Regulatory action will be taken if green snail is detected in imported goods at the Tasmanian biosecurity border.

Biosecurity Advisory 27/2018 – Amendments to Import Requirement 33 – Hosts of Silverleaf Whitefly and (Bemisia tabaci Gennadius) and Tomato Yellow Leaf Curl Virus

​Amendments to Import Requirement (IR) 33 will come into effect from Wednesday 19 December 2018. The regulatory changes to IR33 were declared in a public notice published on 14 November 2018, following a 30 day public consultation on the draft Import Risk Analysis (IRA) in August 2018.

As a result of a number of incursions of the pest Silverleaf Whitefly (Bemisia tabaci) in recent years, in association with imported poinsettia’s for retail commercial sale over the festive season, it was determined special attention needed to be given to reviewing whether or not IR33 remained fit-for-purpose (as per Biosecurity Advisory 22/2018 which is published on the Tasmanian Biosecurity Advisory website). The final version of the IRA for Silverleaf Whitefly (Bemisia tabaci) is available on the Biosecurity Tasmania website

The IRA found that the risk in trade presented by the pest Silverleaf Whitefly (SLW) remains significant and to retain it as a List A Regulated Quarantine Pest of concern to the State. The report also found that another viral pathogen, Tomato Yellow Leaf Curl Virus (TYLCV) which is one of the most significant viral pathogens of tomato in the world today, also remain a List A Regulated Quarantine Pest of concern to the State. Both these pests are not present in Tasmania, as officially supported by Area Freedom Certificate.

This IRA also identified a further viral pathogen that Silverleaf Whitefly can vector called Cowpea Mild Mottle Virus (CPMMV), which is not currently present in Tasmania, and may present some background risk to the State. Though CPMMV is not as serious a threat as that presented by either SLW or TYLCV, it was recommended that the pathogen be declared an ‘Unwanted Quarantine Pest’, under Biosecurity Tasmania’s three tier pest categorisation system.

Biosecurity Advisory 18/2018 - Import Requirement 46 – Tomato Potato Psyllid Hosts and Vectors

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.

TPP is recognised internationally as a very serious pest of solanaceous hosts like potato, tomato, capsicum and eggplant. The potato processing industry in Tasmania is considered to be a very important agricultural industry sector in the State generating $100 -150 million per annum.

The Import Requirement 46 – Tomato Potato Psyllid Hosts and Vectors is effective from 22 June 2018.

Biosecurity Advisory 17/2018 - Soft-shell clam detected in south east Tasmania

The Department of Primary Industries, Parks, Water and Environment (DPIPWE) is investigating the detection of the introduced soft-shell clam on a beach on the Prosser River at Orford in south east Tasmania. 

The clam is a large bivalve marine mollusc and genetic sequencing has confirmed it is Mya japonica. Soft-shell clams are native to the Northern Hemisphere, and this is the first detection of soft-shell clam in the Southern Hemisphere.  The response to this detection is being managed in accordance with the National System for the Prevention and Management of Marine Pest Incursions within nationally agreed protocols.

Soft-shell clams can grow up to 150 mm and typically live in sand, mud and gravel in shallow sub-tidal and intertidal zones. The clam exists beneath the sediment surface burying itself up to 50 cm deep. It uses long siphons, which pump water for respiration, feeding and spawning.

Considered an invasive species for their potential to outcompete native species for habitat, Mya japonica represents a potential marine pest risk to other areas of Tasmania and Australia through the spread of larvae on water currents.

Biosecurity Tasmania is currently investigating appropriate surveillance methods to understand the extent of the soft-shell clam incursion and possible response options, including if eradication is feasible or if control methods should be adopted. DPIPWE will pro-actively engage with all biosecurity and scientific groups, the seafood industry, the local councils and communities on this issue to determine the best future strategy.

It is very important that the clams are not collected or moved to other locations.​

Anyone finding what they suspect to be a soft-shell clam are encouraged to contact DPIPWE on telephone at 03 6165 3777 or email: invasivespecies@dpipwe.tas.gov.au

Images of the soft-shell clam can be found on the DPIPWE website at www.dpipwe.tas.gov.au/softshellclam

Supplying a photograph of the suspected soft-shell clam would assist in identification.

Biosecurity Advisory 16/2018 – Caring for sheep and livestock in extreme weather - Animal welfare alert

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:

  • shallow breathing in order to reduce the rate of respiration (that is, rapid respiration or panting causes heat loss)
  • shivering
  • seeking shelter
  • huddling together

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. Visit the BOM website for more information: http://www.bom.gov.au/jsp/watl/rainfall/pme.jsp
