South Australia (SA) informed the Department of Agriculture and Food, Western Australia (DAFWA) of changes to entry requirements for Green snail (Cantareus apertus) host material from Western Australia which came into effect from 14 March 2017.
Biosecurity SA has designated the entire state of Western Australia (WA) a risk zone for Green snail.
New definition of Green snail host material
The new SA plant quarantine standard defines Green snail host material as:
- soil, plants and plant material (including cuttings and bare rooted plants but not bare-rooted trees provided they have no leaves and fruit)
- leafy vegetables, all peas, all beans, asparagus, strawberries and strawberry plants
- cut flowers
- turf
- hay, straw and other baled fodder
and provides guidelines on relevant entry requirements for WA produce.
Please note, “Topped” root vegetables free of soil are exempt from this condition.
Leafy vegetables listed as green snail host material are listed in table attached.
Entry requirement guidelines for WA produce to SA
As a result of the SA changes, all WA growers will now be required to bait their properties, and be inspected by DAFWA to enable certification for export to SA.
Any baiting that might be required can only commence on April 1st at the commencement of the green snail activity period (April to November inclusive), and while SA have indicated that there may be some departures from the standard Green Snail baiting protocols, DAFWA are currently in discussions with SA and will provide appropriate guidelines to growers as soon as possible.
Growers exporting produce to states other than SA, and whose produce transits through SA to the final destination are not required to comply with the recent changes imposed by SA, and can export in accordance with the requirements in the national Green snail protocol for these states and territories.
Contact the department
As requested in the previous information, to help ensure inspectors are available to meet industry demand for certification for produce to SA, please contact the department if you grow green snail host produce as listed above.
DAFWA is urgently seeking information from growers of green snail host products currently exporting to, or considering exporting to, South Australia including:
- the size of your property, and
- if a mixed-use property, the proportion of your property on which you grow host products.
